Flower reasonable choice and use of herbicides

1 according to the size of Ages medication a biennial woody flowers , whether planting seedlings or cuttings , seedlings are present its tender branches shallow roots , root underdevelopment, poor tolerability , hence should be used when spraying low doses . Commonly used herbicide oxyfluorfen , prometryn and so on. Generally applied before the flower bud marinated pharmaceutical toxic soil , can prevent slips, dicotyledonous weeds, valid for one month , does not affect seedling growth .

(2) According to the degree of precious flowers medication is generally expensive flowers on the environmental conditions and management requirements are relatively high , from a safety point of view , the choice of foliar treatment , such as using the " feeder " and other herbicides formulated as 0.3 to 0.4% concentration liquid, with smearing weed control , avoid using aerosol low pressure sprayer spray drift leading pharmacy has caused injury to seedlings . There is also available indigenous pesticide poisoning .

3 According to the growth characteristics of medication smiling flowers , camellia , magnolia and other flowers as leathery leaves , waxy layer on the leaves , and some conifers with fragrant flowers and leaves of butter, these flowers and strong resistance , it can be directly using the " feeder " and other systemic herbicide to do foliar treatment . Some flowers and leaf quality thin , wax less , such as Tau , France holly, Indus , etc. , and some flower leaves are fluff, such as hibiscus, Mama rust ball etc. These flowers are not appropriate to " feeder " direct spray , garden hand sprayers optional efficient " Gallant " on the stems and leaves do targeted treatment , both to control grassy weeds , but also to ensure the safety of seedlings .

4 Classification according to medication woody flower flowers resistant to herbicides generally stronger than the herb flowers . Flowers on the grass suitably selective herbicides , such as " Gallant ", " grass g ," " Take fishing net ", in doing shoots with flowers growing season . On coniferous woody species such as cypress , larch, cedar , etc., can also use the " feeder " doing foliar treatment . For some broadleaf woody species such as ash , acacia, Bauhinia, hibiscus and other species more sensitive to insecticides , can do oxyfluorfen soil treatment, wash with water after application required seedlings, nursery stock to ensure safety .

Do not let the plant protection Yaoxie become the soft underbelly of landscape development

In recent years , China's fruit trees , forestry and nursery industry is developing very rapidly , and in some places even have developed into leading industries. However , relatively speaking , garden plant protection aspects of development is relatively slow Equipments , so many seedlings of agriculture, farmers in the selection Yaoxie when , but only from the field of plant protection Equipments choose , naturally less than ideal control effect , making a garden plant protection Equipments career development of weakness.

Despite the orchards, nurseries , gardens belong to farming, but after all, Daejeon grain, vegetable crops are different , so they took fruit trees and other landscape trees , the most obvious feature is the large tree topped , use common field sprayer to combat their diseases, pests , certainly not achieve the desired results , and the operator toting garden sprayers , standing on a high stool, ladder spray also dangerous. Therefore, many farmers , growers are hoping spray trees should be in the " high range , automatic target , to prevent drift and electrostatic spray " on an issue , so that the ortable sprayers mist sprayed only achieve the desired elevation , but also evenly attached to the leaf plane surface , reducing the height droplet drift, to achieve good control effect , although currently heard of these products listed, but foresters , farmers still difficult to buy .

In short , the development of Garden Plant Protection Equipments are the majority of farmers , growers and farmers hoping for seedlings , but also the requirements of the city garden workers . Therefore, I hope the relevant departments and enterprises to accelerate the research work in this area , so that has been identified as soon as the market advanced Yaoxie make garden work more modern plant protection concepts and requirements.

Reasonable application of trichlorfon

Trichlorfon (C4H8O4Cl3P) an organic phosphorus esters in fish disease control with high efficiency , low toxicity, residual less residue shorter advantages.

In order to reduce and avoid the generation of resistant parasites on trichlorfon improve trichlorfon concentration range in a safe use of effects , you can take the following measures:

( 1 ) Rotation drug prevention and treatment of parasitic fish diseases , not long-term single-use trichlorfon a drug to cut pathogens resistant populations formation.

( 2 ) combination therapy can not only play rid combination pests, increase efficacy , reduce costs , and there is a clear inhibition of the development of resistance and to overcome the effect. Such as : 90 % of the crystal trichlorfon and ferrous sulfate mixture (0.5:0.2) 0.25ppm control carp Sinergasilus concurrent with Shi ; 90% crystal trichlorfon and surface alkali mixture (1:0.6) 0.25ppm can kill three generations worms, ring worm .

( 3 ) In order to enhance efficiency for trichlorfon for trichlorfon efficacy, reduce their parasite resistance , perfume sprayer in addition to strictly symptomatic medication and serious medication, reasonable compatibility synergist is one of the ways to improve the efficacy .

The rational application of trichlorfon

In the process of fish disease control how the rational use of trichlorfon , fishery production is a common concern . Rational use of trichlorfon main attention to the following points:

( 1 ) Use trichlorfon control parasitic fish diseases , pathogens objects shall different pH values ​​and water quality and proper adjustment application rate , pH of 6.5-7 in the water can be slightly increased application rate , pH value of 8 -9 can reduce the dosage .

( 2 ) In order to improve fish disease control effect, reducing resistance , you should rotate the use of drugs .

( 3 ) when administered trichlorfon , not adding an alkaline substance or alkaline washing , iquid sprayer to prevent the formation of toxic substances methoxy acid chloride , livestock and fish to avoid poisoning.

( 4 ) trichlorfon original drug with acidic , sprinkle medicine is best not metal containers to prevent corrosion ; such as metal sprayer after use , must be promptly wash with water.

Herbicide use of technology to improve

Play herbicide weed herbicide has its own performance characteristics , we must increase the use of technology to maximize the effectiveness of the herbicide weeding , weeding in order to achieve good results, and to reduce or avoid injury from occurring. To correctly handle the following relationships .

1 , application and climate relationships . When the weather is dry or when the wind is spraying, will increase the amount of liquid evaporation and drift , weeds, leaves , soil surface adhesion of the liquid is reduced , resulting in decreased herbicidal effects should be avoided in the dry and windy weather conditions The following spraying.

2 , application and temperature. Many herbicides increased activity in high temperature conditions , at low temperatures decreased activity , slow down dead grass , generally greater than the daily average temperature 8-10 ℃ degrees conducive efficacy of play . However, some herbicides in the day when the average temperature is about 5 ℃ low pressure sprayer spraying , you can still get a good herbicidal effect .

Such as fenoxaprop , alkynyl oxalic acid, tribenuron , azole grass ketone. In the days before winter the average temperature is about 5 ℃ ( no freezing at night as well ) to use , even after the winter to get a good herbicidal effect .

It should be noted with isoproturon head warm in cold tail spraying , cold spraying should be stopped 2-3 days before , or can produce cold injury.

3 , the relationship between pesticide and humidity . Whether soil or foliar treatment enclosed needs to have suitable soil moisture , drought conditions are not conducive to the efficacy of the play , you should avoid spraying too dry conditions .

4 , pesticide and water relations . How much water when spraying is related to the amount of liquid adhesion and uniformity of spraying , thus affecting the herbicidal effect . Asked not to re-spray herbicide , does not leak spray , repeat some easy to produce injury , where leakage spray weeds die. According to practical experience , as a soil closed when weeding , mu liquid volume of 45-60 kg as well ( hand sprayer 3-4 buckets of water ) , foliar treatment agent to 30-45 kg ( 2-3 buckets of water ) as well .

5 , application and preparation Quality. Crushing smooth soil surface is conducive to the formation of liquid membrane closure , weeding effect. Uneven soil surface , and large clods of soil surface is not conducive to closed , and because of freezing and thawing in winter , a large clods broken, resulting in increased spring the grass , reducing the herbicidal effect .

Rice herbicide injury prevention

In the rice growth process, timely weed killer sprayer spraying Brassinolide regulate , enhance plant resistance to diseases, to reduce the incidence of disease . Brassica cable lactone has a strong physiological activity , which can activate the physiological activity of rice to improve rice photosynthesis, enhanced rice stress tolerance, disease resistance , and promote rice growth , and can effectively prevent sheath blight , rice blast and other diseases place.

Rice injury prevention , in addition to the insect pest forecasting based on plant protection departments to choose the appropriate pesticide conditions , and in accordance with the full requirements of the specification suitable period for evenly spraying water outside , backpack weed sprayers spraying can be added while Brassinolide together spraying. The test showed that Brassinolide with some neutral weak acid insecticidal, fungicidal and other drugs used in combination f Queensland , has obvious synergies. In the case of the same dosage , mixed together with spraying Brassinolide more significant control effect , can effectively avoid excessive pesticide phytotoxicity on crops .

Rice pesticide use but also can be to

Dressing method .

Dressing method is the pharmaceutical and seed evenly mixed together , so that the seed surface covered with a layer of powder or emulsion , for the control of soil pests , insects and seed-borne diseases seedling method of application . This method is suitable for dusts, wettable powders, emulsifiable concentrates , liquid dosage forms , with high efficiency, good control effect , no effect on the natural enemies , without water restrictions, etc. . In powder dressing , can be placed on pesticides and seed dressing , or other apparatus within the uniform mixing . With wettable powders, emulsifiable concentrates or aqueous dressing should press with a good proportion of dilution liquid, then spray the liquid spray to the seed , while spraying edge mix . After dressing , preferably 2 to 3 days pile boring , so that agents are sufficiently adsorbed seeds , pesticides due performance in order to play .

Dipping method .

Dipping method is to pesticides diluted with water , put the seeds or seedlings soaked in liquid , that the seed and seedling absorption and adhesion some agents, for the control of pests and diseases , and promote seedling root bud development . This method is suitable for cream, liquid, wettable powder formulations , with flower workers less seedling effect, with less pesticides and other advantages.

Bait method .

Bait method is to use bait ( various grains , bran, sugar , potatoes, cooking oil residue , etc. ) and their counterparts with stomach toxicity pesticide mixing bait , scattered in the fields, for the control of soil pests , rodents application methods .

This method is suitable for dusts, wettable powders, emulsifiable concentrates , liquid dosage forms . When in use, should be selected palatable food prepared fresh bait , and according to the feeding habits of insects and rodents , on a sunny day early in the morning or evening Bait . Adding crop seedling baits usually in the evenings or rain , fruit tree sprayer the effect is better.

Fumigation .

Fumigation method is the use of fumigants or easily volatile agents produced a sterilizing gas to insecticide spraying method . This method is suitable for warehouses, greenhouses , soil or crop lush place , with anti -efficient, fast-acting , etc., but the operation is technically demanding, spraying conditions are more stringent . Fumigation in the warehouse , to ensure a good seal , should be adequately ventilated after fumigation , the gas escapes . Soil fumigation , the effect can be closed with water , i.e. in the treated soil surface layer of water spray , can delay the fumigant to escape. Between the lines in the crop fumigation , should choose dense crops and appropriate temperature conditions , a sunny day .

Fumigation method .

Fumigation method is to smoke or ignite fuming fuming original drug to direct heat application methods of pest control . This method is suitable for use in a closed environment ( such as warehouses ,manual sprayer greenhouses ) or canopy high places, such as the growth of field crops later use . Pharmaceutical form of smoke gas diffusion have better penetration and proper settlement of space to stay longer, but not overly floating drift , so as to achieve good results.

Hot season spraying pesticides security can not be taken lightly

In the spraying period not drinking, smoking , drinking , eating , etc., can not be directly Cazui hands , face, eyes, absolutely not allowed to spray each other frolic . Wash thoroughly with soap after household sprayer spraying hands, face and mouth , pesticide-contaminated work clothes to be washed and replacement bulbs . Pesticide spraying operations staff time per day is generally not more than six hours .

Applying excessive toxicity , pesticide poisoning obvious place to erect signs within a certain time ( harvest interval ) prohibit grazing , harvesting , to prevent livestock poisoning . And pay attention to compliance with the relevant provisions of the safe use of pesticides is prohibited highly toxic pesticides in vegetables, fruit , tea and other use .

After spraying sprayer should be cleaned and kept clean and safe custody ; Guo Cheng Zhongsheng preparation and handling of pesticides packaging materials , centralized processing , nor for holding grain, oil, wine, water and other food and feed.

After water power sprayer spraying fruit and other vegetable crops , must be in a safe interval after harvesting and consumption. To soak and rinse before eating to eliminate pesticide residues in vegetables .

With special chemical properties and performance of pesticides, must be read carefully prior pesticide label on the package , in accordance with label precautions for personal protection and operation.

Suggestions to improve the pesticide market

For the current pesticide market several major problems , make the following recommendations in order to improve domestic pesticide usage.

1 . Pesticide safety training efforts to increase scientific , training dealers and farmers awareness of safe medication . The grassroots agricultural workers , dealers and farmers for safe and rational use of pesticides knowledge and technology information and training , agricultural sprayers the formation of a scientific and rational use of pesticides conscious atmosphere. Meanwhile, for the occurrence and control of pests of different crops during the timely organization of scientific and technological personnel to go to the grassroots and providing technical guidance to carry out pollution prevention technology training to enable farmers not only master the techniques of scientific medicine , but also fully aware of the ecological environment and pesticide contamination harm the health of people .

2 . The establishment of safe use of pesticides demonstration fields, visually guide the farmers medication safety . In the demonstration venue , in strict accordance with technical regulations , timely and rational use of pesticides , with minimal dose for maximum control effect, so not only cost effective , but also protect the ecology.

3 . Introduction of testing new pesticides, and actively promote the new pesticides. Strengthen the new pesticide testing, demonstration and promotion , screening efficiency, low toxicity , low-residue pesticides, bio-pesticides, to replace the highly toxic , high residue pesticides. Expand insecticidal lamps , sex attractant agent physical , biological technology area , and actively carry out ecological controlling pests and biological control techniques popularized .

4 . To promote the introduction of new Equipments , improve the utilization of pesticides . Spraying machine must accelerate the upgrading of application techniques while actively making improvements , changing the traditional high-volume, low -capacity large tree sprayer spray droplets and fine droplet spray . Establishment of specialized defense team , promote motorized sprayer , improve control and reduce pesticide waste and pollution.

5 Strengthening pesticide residue monitoring, production of pollution-free agricultural products. Pesticide residue monitoring job is to protect people's health needs, is to improve the competitiveness of agricultural exports needs, but also the sustainable development of China's agricultural needs . Look perfect as soon as possible pesticide residue testing equipment, staffing , will monitor pesticide residues as a key task .

6 . Strengthen market management of pesticides . Pesticide management departments should strengthen law enforcement efforts to rectify the pesticide market , and resolutely fight against counterfeit pesticides, pesticide labels failed to purify pesticide marketing channels for the safe use of farmland to create a favorable market environment. Punished for violations , improve pesticide production, management, legal awareness of users , crack down on illegal production, management, use of pesticides behavior , to prevent illegal pesticide production, management and use , as to create conditions for the safe and rational use of pesticides .

Lawn Weeds against these can not be ignored

Improved application techniques . Herbicide spraying must be uniform , we can not re-spray , it can not leak spray . If adjacent plots are herbicide sensitive plants , will have to take quarantine measures , remember when the wind is not spraying so as to endanger the adjacent sensitive crops . Sprayed drug use bleach rinse the sprayer after a few times and then further use on other plants . Herbicide farm sprayers is best dedicated to avoid hurting other crops .

Herbicides strictly against the water . Wo to eliminate , for example, the normal amount of 90 ml per acre , requires watered 30 kg , or two spray water , then the concentration of effective weed herbicide concentration . Excessive water , herbicide concentration is low , it will affect the herbicidal effect ; water is too small, the herbicide at high concentrations, inhibit the growth of grass light in weight is likely to cause injury ; therefore , spraying herbicides must be in strict accordance with the instructions against water , you can use the graduated cylinder , beaker assist weighing, try to make it cool and accurate.

In addition, high organic matter content of the soil particle size , herbicide adsorption capacity , and soil microbes and more vigorous activities , drug dose is degraded , may be appropriate to increase the dosage ; while loamy coarse sand , the adsorption amount of pharmaceutical small pharmaceutical molecules in the soil particles are mostly free state , activity, prone to injury , the dosage can be reduced appropriately .

Most herbicides in alkaline soil stability, not degrade , so Vinca longer easy to Succeeding seedlings produce injury ,perfume sprayer  should be sprayed on the type of soil in advance as possible , and use caution.

With respect to chemical weeding operations, generally speaking spraying to do five to see : a look at the size of the lawn recruits , two to see how much weed leaf , three to see if the weather is sunny, dry and four to see the soil moist , sandy soil five to see who is stronger adhesive .

Low volume sprayer Precautions

( 1 ) Preparation before use . In the use of ultra low volume sprayer , you should check the machine parts are complete, installed correctly , the connection part is solid and reliable, the cage rotation is flexible and comfortable ; adding gasoline to the engine and engine oil mixed oil dubbed , should Xianxiang liquid tank and add water spray test and observe the tank and the liquid flows through the pipe without leaking, tumble spray droplets are normal ; before use, but also according to control objects in under the guidance of professional and technical personnel selection type of chemicals and formulations to suit ultra-low volume spraying should prevail. The drugs available household sprayer throttle control .

( 2 ) using the operation. Spraying pesticides , machinery parts subject to normal operation , the operator first walking, then open the infusion switch, while walking to always keep the same speed , stop spraying, first turn off the infusion switch, and then be shut down. When spraying , pay attention to the prevailing wind direction downwind should begin to try the spray direction consistent with the natural wind direction , wind spraying is not allowed . Field spraying application side spray technology, not facing the nozzle orifice crops, but crops have a certain angle , the angle depending on the size of the natural wind speed to be, the principle is the wind speed , the angle should be large , wind -hour angle to small . Spraying time should not be selected in the hot noon , natural wind is greater than 3 , should not be implemented ultra low volume spray. In warehouses , greenhouses , etc. When spraying spray time not too long , in order to prevent occurrence of poisoning people . When the spray liquid into the cage of the bearing part , should bearings removed, cleaned with kerosene or gasoline , according to the instructions in the bearing interior requirements add some molybdenum disulfide solid lubricant or calcium based grease lubricated , and then install the cage ; in tree sprayer spraying, nozzle atomizer tumble do not touch crops, in order to prevent damage to the cage ; join the tank liquid not too full , to prevent overflow , if the overflow , immediately wash clean. After each use , to the tank , the residual liquid infusion tube release , the whole machine wipe clean ; spray after the operation , in custody prior to collection , in addition to the tank , the liquid inside a clean residual oil poured outside , but also a comprehensive cleaning, metal parts to rust oil painting , and then stored in a cool ventilated .

Buy farm machinery to look at the appearance of

In assessing the quality of agricultural machinery products , in general , the product appearance quality to some extent reflects the intrinsic quality of the product . Can also be seen from the external observation of the quality of product is good or bad .garden water sprayer  The general appearance of agricultural machinery requirements are:

1 ) Products should be no bump, damage, and refurbishment of signs , painted some places can not have missing paint , primer for ferrous materials must be rust .

2 ) The seam welds should be smooth and firm.

3 ) with fuel, lubricating oil , liquid , water and other liquid containers, pipes , fittings , etc. tight , there can penetrate , leaky places . Pneumatic device containers , pipes, fittings , etc., can not leak . Sealing surface can not have a drop of oil leakage , various parts of the gap to be consistent.

4 ) castings should be no holes, blisters, burrs, plastic colors, the wall thickness should be uniform , box , etc. garden water sprayer are not allowed cracks , tires, V-belts and other rubber parts without aging and deformation.

5 ) are not adjusting screws or screw application after immersion tighten the screw nut is threaded at one end exposed outside the plane , at least two screw buckle, but can not exceed l0mm. All non-adjusting screws , bolts, nuts should be tightened indeed , according to the provisions of the locking means ( locking nuts, cotter pins , wire , washers, etc. ) locking . All adjustments of agricultural machinery , precise and reliable lubrication part ; all rotate , Transmission and control devices operating flexibility without catching place .

6 ) The whole machine should be no distortion ; throughout parts intact.

Classification of water mist extinguishing system

Mist nozzles, containing one or more orifices, means can be atomized droplets, which is the most critical parts of the system. Produce water mist nozzles principle particles of the following five methods, the liquid with respect to the surrounding air is released at high speed, because the speed difference between the liquid and air and water particles to be shredded; liquid touch to a fixed surface, to produce water particles due to collision; two shares a similar flow components collide particles per water flow are formed; electronic ground vibration or liquid particles into water (ultrasound and electrostatic atomizer); liquid in a pressure vessel is heated to above its boiling point, atmospheric pressure is suddenly released to the state (liquid spray burst).

According to different standards of water mist systems can be divided into the following systems:

Low pressure system, the working pressure is less than 12.1bar (175psi *); medium voltage systems, working pressure 12.1bar (175psi) ~ 34.5 bar (500 psi); pressure systems, working pressure greater than 34.5bar (500psi).

Local Application System (Local Application Systems), such as protection of steam turbine bearings, refinery heat pumps; total flooding systems (Total Flooding Application Systems), to protect the entire protected area, such as gas turbine engine room.

Prefabricated systems (Preengineered Systems), such as compressed gas cylinders driven Shuangliu systems, cylinder and tank has several kinds of specifications, are processed in the factory, the design size of the area under the protection zone to choose; Engineering Systems (Engineered Systems) , its composition and working methods similar to conventional deluge system (Deluge Systems).

Single-stream media system (Single Fluid Media Systems) and dual media garden sprayers  spray system (Twin Fluid Media Systems). Single-stream media system is the only water as the extinguishing agent supply pipe to the nozzle by the way. System consists of a nozzle, water pump deluge valves, detectors and controller. Double medium spray system, water and atomizing medium are supplied by different lines, and in the mixing nozzle, the collision produces water particles, the shape of the liquid sprayer spray nozzle shown in Figure 3. Atomizing medium is divided into two parts, one for pushing water storage tank, and the other way directly supplied to the nozzle. Water storage tank at atmospheric pressure, fire pushed by the high-pressure gas into the protected area. Atomizing medium is mixed with water and can produce a high pressure water mist air or other gases.

Problems in orchard spraying

1 arbitrarily increase concentration, close spraying effect solution uniform coverage spraying some friends of farmers affected by bad habit, difficult to control pests and diseases encountered often only increased the dosage, without increasing the amount of water, causing the liquid concentration increased, and the liquid is less difficult in fruit bottle sprayer sprayed uniformly thoughtful, affecting control effect, and even cause injury. Some growers in the spraying nozzle too close with fruit trees, fruit trees leaves under the impact of high pressure are turned up, so easily damaged fruit surface.

(2) spraying pesticides like some fruit trees that drug wash spray the better, like to spray fruit trees have leaves dripping, thinking that we go. But just the opposite, worms down not by flushing with fresh water, but by the suction, tag, fumigation and to kill, and a large easy to make water plant stomatal closure, but absorb less water and more, this spraying method waste, investment large, poor results. And easy to make fruit calyx dip too much liquid at the plot, the long-term accumulation likely to cause injury, affecting fruit quality.

3 sprayer pressure is too small, motorized  tree sprayer nozzle is too large, poor atomization, resulting in reduced droplet density is taken sprayer hydraulic atomization, spray some domestic enterprises, especially some small production companies due to their technical limitations, mainly the production of pressure sprayer. Farmers spraying pesticides in small, often due to the pressure caused by the crown, not spray within the Church, forming leak spray, motorized sprayer takes the pneumatic atomization, some farmers friends in order to save time, especially some of the staff in order to provide paid services to improve spraying efficiency, often intentionally poke the nozzle orifice gasket big, not knowing that after such a transformation is to improve efficiency, but the atomization effect is reduced, will inevitably affect the control effect.

Spring weed controlling techniques and precautions

According to Weed, for different stubble, grass love grass phase, selecting the right agent, a comprehensive medication. Controlling suitable period to seize the cold tail head warm, the temperature stabilized at about 10 ℃ timely medication.

First, the control methods

Controlling weeds in wheat Tiandan cotyledons, 15% of wheat per acre with pole 40 g or 6.9% Puma 80-100 ml; controlling broadleaf weeds, broad acre with 20% wins 20-30 ml +10% wheat sword 15-20 g; Mixed plots per acre with 15% wheat pole 40 grams (or 6.9% Puma 80-100 ml) Width wins 20-30 ml +20% +10% wheat sword 15-20 grams.

Rapeseed controlling monocotyledonous weeds per acre with 10.8% high cover 40 ml; controlling broadleaf weeds per acre with 30% Benazolin 50-60 ml; Mixed plots per acre with 10.8% high cover 40 ml +30 % Benazolin 50-60 ml.

Second, note

With prospective dose, with enough water, water power sprayer 60-70kg / acre, Mist Sprayer 20-30kg / acre, uniform fine agricultural sprayers spray to ensure the control effect; barley banned Puma, rape fields disable Ethametsulfuron, cabbage type Brassica juncea disabled Benazolin, Catcher completely banned green, A Huang Long as their mixtures, to ensure safety after the crop; application equipment should be cleaned after use.

Note the use of pesticides hot season

Most pesticides and toxic substances for the chemical substances in the control crop pests plays a pivotal role. However, if the use or improper operation can easily cause human, animal or crop phytotoxicity poisoning. Summer hot season, at the peak of a variety of pests and mixed hair, prevention of drug use is more frequent in pesticide use should pay attention to the following points:

1, the preparation of liquid when dispensing personnel should wear rubber gloves, in accordance with a prescribed dose of medicine, said measuring liquid or powder, are not free to increase or decrease the dosage. Preparation of liquid mixing prohibited by hand directly.

2, mixed drug use tool to stir, how much, how much mix, as used with the configuration of the liquid; mix over the drug should be used seed sowing machines. As with the artificial hand or point spread species, should wear rubber gloves. Right mix of seeds over the remaining drug should be destroyed, not as food or feed use.

3, where the sickly, suffering from skin diseases and pesticide poisoning and other diseases has not been restored healthy, lactating, pregnant, menstruating women, skin lesions healed, shall not be suspended spraying or spraying operations.

4, the use of pesticides should be interlaced sprayer spraying spray can spray while swinging left and right sides, to downwind spray. Try to avoid the midday heat period winds and spray. And note that the liquid medicine is not overfilled bins to avoid spray liquid shake out operations outside the barrel, pollution caused by pesticide poisoning symptoms of their bodies.

5, should be carefully examined before spraying Medical Device switches, connectors, etc. screws are tightened to avoid "drip, run, run, drain" caused by pesticide pollution. Clogging the garden hand sprayers process, the application of water rinse after troubleshooting. Absolute prohibition of mouth pipetting nozzle or strainer.

6, in the spraying period of not drinking, smoking, drinking, eating, etc., can not be directly Cazui hands, face, eyes, absolutely not allowed to spray each other frolic. Wash thoroughly with soap after spraying hands, face and mouth, pesticide-contaminated work clothes to be washed and replacement bulbs. Pesticide spraying operations staff time per day is generally not more than six hours.

7, the application of high toxic pesticide poisoning obvious place to erect signs within a certain time (harvest interval) prohibit grazing, harvesting, to prevent livestock poisoning. And pay attention to compliance with the relevant provisions of the safe use of pesticides is prohibited highly toxic pesticides in vegetables, fruit, tea and other use.

8, should be promptly cleaned after spraying water power sprayer and keep it clean safekeeping; Guo Cheng Zhongsheng preparation and handling of pesticides packaging materials, centralized processing, nor for holding grain, oil, wine, water and other food and feed.

9, after spraying fruit and other vegetable crops, must be in a safe interval after harvesting and consumption. To soak and rinse before eating to eliminate pesticide residues in vegetables.

10, with a special chemical properties and performance of pesticides, must be read carefully prior pesticide label on the package, in accordance with label precautions for personal protection and operation.

A Brief History of the hydrocyclone

Hydrocyclone early in the 20th century in the late 1930s in the Netherlands appears. Hydrocyclone is the use of rotary flow grading equipment, and is also used for thickening, dewatering result sorting, its structure is very simple, is dominated by a hollow l and a tapered cylinder 2 is connected from. cyclone diameter of the cylinder represents the specification. its size varies greatly from 50mm to 1000mm, typically 125-500mm. inserted in the center of the cylinder an overflow pipe 5 ,weed sprayer there is tangentially connected to the mine pipe 3, in the lower left Spigot cone 4 slurry under pressure,? along the ore fed into the cyclone tube inside, then limit the cylindrical wall perishable rotary movement of coarse particles due to inertia and centrifugal force wall was thrown and gradually downward flow discharged from the bottom of a grit. fine particle moving speed of the lower wall, is driven by the liquid flowing toward the center from the central overflow pipe outflow become overflow.
Hydrocyclone is a high efficiency rating, off the mud equipment,garden sprayer backpack due to its simple structure, easy to manufacture, processing capacity, has been widely used at home and abroad. Its main drawback is the large power consumption, and in the high-pressure feed Mine is badly worn. adopt new wear-resistant materials, such as cemented carbide, silicon carbide and other production Spigot and wear parts to the mine mouth can partially solve this problem, in addition, when used in closed-circuit grinding of grading, because of its small volume, no buffer against fluctuations in ore ability as mechanical grading machine work stable.

Development of manufacturing processes nozzle

Nozzle consists of many parts composition, its manufacturing process and mechanical equipment as science and technology advances also increased, the article talked nozzles in various industry applications, today introduced the next nozzle manufacturing process of development, agricultural sprayers the main difference is divided into the following:
1, blank refining technology, is replaced with a precision rough forging forging rough rough, raw material cost savings but also saves processing costs
2, precision drilling technology, the original mechanical drilling has been changed to a computer-controlled laser drilling and drilling electrolysis, the smallest aperture of 0.1mm can be processed
3, the welding techniques, conventional resistance welding and TIG welding to the main, is used in order to improve the high-temperature vacuum brazing and high energy density electron beam welding
4, surface grinding technology, using a single disk plane grinding function processing a more smooth, refined products,back sprayers its parallelism can be achieved 0.0003mm

How to extend the life of electric sprayer

Sprayer because easy to use, high efficiency, loved by more and more farmers, has now become a major greenhouse pest tool. However, electric sprayer more "delicate", once in use, improper operation, maintenance is not timely, it is prone to failure. How to maintain,garden water sprayer it can prolong the life of sprayer is recommended farmers should do the following.
First of all, the first official use, check all connections for leaks. When used, install water spray test, then loaded agents. Dosing when the first Canadian Pharmacy, add water, the liquid's surface can not exceed the safe water line. Before spraying, electric sprayer opens in advance, so that the barrel pressure up to a pressure of work, to ensure a smooth spraying.
Secondly, the sprayer after use, to first put the barrel body electric sprayer, hose, spray bar and other parts clean, paying particular attention to clear the pump and liquid grease on the bottom of the barrel recess soil. Because the majority of pesticides on sprayers have some corrosion, therefore disabled, to promptly wash it again with lye, then rinse with water. Especially such as Bordeaux mixture sprayed pesticides after corrosive, preferably with lye soaked 1-2 hours. Pay attention to prevent rust. Those who can disassemble the parts, must be removed to wash clean. Lance, nozzle inner wall to use the oil painting, avoid damp rust.
If you do not use the spray near term, the main components should be clean, dry bottles in a cool dry place. If the long-term need,liquid sprayer  all metal parts have to be buttered, to prevent rust.
