Use of these pesticides

Smog laws. Oil solution of the pesticide dispersion state of a method of application of smoke . Smoke France must take advantage of special equipment to put oily smoke pesticide dispersed state . Smoke generally refers to the diameter of 0.1 to 10 micron particles in the air dispersion. Solid particles are known as smoke, fog liquid called . Droplets of liquid smoke is left after evaporation of the solvent a solid prills . As the smoke particles is small, suspended in the air a long time, deposition distribution, control efficiency higher than the general law and dusting garden pressure sprayers spray method .

Shi Rafah . Throw granular pesticide application methods . Coarse particles of granules , the applicator has little effect by the air , ground and essentially does not occur easily drift , especially for the ground , paddy fields and soil treatment . Withdraw facilities using a variety of methods, such as hand throw ( toxic agents ) , manually operated Caesar granulator throw , throw motorized Sarah machine , soil Shi granulator spraying and so on.

Wipe application methods . This is the use of pesticides in recent years the emergence of new use of technology, in terms herbicides have been large scale applications . The specific method of application , is a group of short , composed of bare nylon rope , the rope end is connected with the herbicide solution , the capillary and gravity flow of liquid into the drug rope , when the spraying machine through the spread of weeds field , the absorption of the drug ropes higher herbicide weed growth can wipe the top , but not to rub the crops grow shorter . Wipe herbicide hand sprayer spraying method used for dosing , significantly lower than normal sprays . Because almost all pharmaceutical facilities on the weeds , had this application methods crops from injury, nor droplet drift , control costs and save .

Vegetable pests spraying techniques

Wide variety of vegetable pests, but can be summarized as suck juices, fresh leafy and boring classes three categories. Each type of pest habits are not the same. According to their character and individuality as well as the growth characteristics of the host, targeted spraying control, make direct contact with the parasite agents, achieve better control effect.

1, spraying techniques and pest infestation habits and living habits are closely related to aphids suck juices and some leaf-eating pests concentrated in the dorsal and twigs parasitic infestation, it should be a "little circle" approach to spraying, namely spray nozzles garden sprayers spray plant leaves bear the first lap, and then spray it buckle in the tender head, thus making contact with all pharmaceutical plants and parasites, to receive better control effect. Spodoptera exigua, beet armyworm larvae daytime hiding old phenomenon, so the growing season spraying control such pests, preferably in the evening. Borer pests cabbage webworm spraying time must be at the peak of hatching.

2, spraying technology but also with the growth characteristics of the host is closely related to the summer cowpea flowering time around in the morning 7:30-10:30, after all this time its petals closed. Cowpea early instar larvae borer infestation dispersed or concentrated, tree sprayer spraying at 9:00 in front as well, so that we can make more fully exposed to the parasite agents, or missed opportunities. Kale leaves covered with a layer of wax, with a biological insecticide Bt Pieris rapae, often adding 0.1% in liquid detergent, the purpose is to reduce the surface tension of the liquid evenly distributed in the leaves, improve control effect.

Potted flowers three common fertilization methods

The growth of potted flowers , in addition to light, temperature , air and moisture necessary conditions , should also have adequate nutrient supply . No matter how good is the soil , after a certain period of time after planting , soil nutrients are exhausted. If you do not replenish fertilizers , flowers, plants will appear emaciated , garden sprayers dead leaves and other phenomena . Thus , fertilization is potted flowers critical conservation process a job. So when fertilization, how fertilization in order to achieve better results?

Generally, fertilization methods commonly used in home gardening has the following three ways:

Basal: Huanpen in the nursery and pre- composting process will be a good fertilizer , mixed according to a certain proportion of the soil, in order to provide long-term growth needs of a method. Fertilizer commonly used to produce their own organic fertilizer , such as the maturity of the cake , bone meal, fried melon seeds , the effect is very good. It should be noted , do not let the roots of flowers to the fertilizer in direct contact , it will easily burn the plants due to hypertrophy .

Dressing: in flowers during the growing season , because the basin is limited, basal lost strength after a long time , can no longer provide adequate nutrition of plants . At this time during the growing season will be based on the needs of different flowers , selective complement a variety of fertilizers. Can also be used with fertilizer organic fertilizer . When the use of fertilizers , plant stems to avoid , sprinkle in the basin ; or watering the fertilizer diluted . Fertilizer use is simple, effective but also fast, but prolonged use causes basin compaction, soil permeability is poor. The homemade organic fertilizer nutrients than the whole, fertilizer long , but also improve the soil , where suggest that you use organic fertilizers , minimize the use of fertilizers. Using homemade organic fertilizer can be diluted with water after watering , you can also shallow around the plant , the same should also avoid the rhizomes.

Foliar fertilization: This method can be managed in time to save for negligence , malnutrition and other phenomena of plants . Convenient and cost-effective . Is diluted to a certain percentage of the fertilizer , the use of flower sprayer spray sprayed directly on the foliage of plants , is absorbed by the leaf .

In addition, the fertilization process but also pay attention to the timing: fertilizer and foliar fertilization , to dry soil in the pot when , when plants absorb best. Even before the first tillage fertilization , so in order to facilitate the rapid infiltration of fertilizer , reducing fertilizer losses.

Sprayers and spraying techniques using point

To ensure trouble-free use and prolong the life of sprayers , and in order to ensure the safety of staff . Sprayer before and after use be sure to make the appropriate checks in the process of spraying pesticides should follow certain precautions.

To check the sprayer before operation of the parts for damage, without leakage, spray is normal , the first trial with agricultural sprayers water spray .

Spraying pesticides , the operator should stand upwind , and pay attention to changes in wind direction , way of walking time to change jobs , try to forward interlaced spraying.

Knapsack sprayer tank can not be overfilled to avoid bending when the liquid from the medicine chest mouth overflow spilled into the spraying people. Select the correct application time should avoid weed sprayer spraying at noon when the sun is strong , because when pesticides , volatile, and the operator sweating, pesticides easily into the body through the pores .

Spraying equipment in the course of the event of failure , should immediately stop work , close the valve , inspect repairs. If it is a pipe or pump sprayer fails, you must first reduce the pressure in the pipeline . Open the pressure in the gas tank , you should first release the compressed air cylinder , to prevent accidents.

After each use , the barrel should be promptly poured the remaining liquid, and washed with water poured dry .

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.

Nozzle arrangement and selection

Arrangement of sprinklers shall cover the surface of hazardous materials to be protected, the number should be based on a single nozzle sprinkler coverage, application height, pitch and protection of objects to determine mist layout should follow the principles of object overwrite protection, while meeting the fruit tree sprayer spray strength requirements.

1, should be based on protection zone height, area, type of fire, the protected object appearance and reasonable choice extinguishing system type nozzle.

2, total flooding system nozzle should be a rectangular, square or diamond-shaped arrangement of the protection zone at the top of a balanced, appropriate for high spatial hierarchical arrangement.

3, the local system should be balanced nozzles arranged around the object to be protected, for higher hierarchical arrangement of objects should be.

Ten, the amount of water required for fire-fighting

Water volume required fire determined as follows:

Single nozzle flow q = k

(Single nozzle flow nozzle Flow coefficient is equal to 10 times by the square root of the nozzle working pressure)

P-nozzle pressure Mpa

K-Nozzle Flow coefficient

System design flow Qj = 1/60

(System design flow rate equal to the system starts the same time open the flow and spray nozzle)

Qj-system design flow (L / s)

N-system starts at the same time the number of manual sprayer spray mist nozzle

Qi-spray nozzle of the actual flow rate (L / min), shall be the actual working pressure spray nozzle

Water system

W = QjXt (L)

W-system water (L)

T-mist injection time (min)

(Equal to the water system by system design flow and water mist injection time)

System storage capacity

Wc = W (L)

Preset storage capacity of water mist fire extinguishing system must be based on the manufacturer's technical criteria.

Ultra low volume sprayer after use guidelines

After each use, to the tank, the residual liquid infusion tube release, the whole machine wipe clean; chemical sprayer 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 kept in the shade.

Faults and troubleshooting ① reduce the amount of spray or not to home garden sprayer spray. Repair, if found to be incorrect throttle valve spool position can be a good re-spool position; infusion switch if they are blocked, the infusion should be cleaned switch; throttle orifice if they are clogged, clean the throttle valve Kong; the case of the liquid-axis head clogging infusion should be cleaned shaft hole; if they are not pressurized tank or leak, refillable pressurized connector with the notch toward the fan; the case of tank lid is not tightened should be re-tighten the tank lid. ② obviously thick fog particles or transfer cage speed is low. If found to be gasoline engine speed is not enough, you should adjust or repair gasoline; cage bearing the case of oil, and add lubricant bearings should be cleaned; if they are bearing wear, should be replaced with new bearings; tumble if they are clogged or broken nylon nets should be cleaned or replaced grille.

How to use spray

As agricultural sprayer production and agricultural machinery fortune good helper, not only will buy, good maintenance and proper operation, maintenance, maintenance of machinery is also very important.

Accordance with the "agricultural machinery repair, replacement, return liability" Article 23 stipulates that any person caused by a mechanical failure, not to implement three. To this end, the majority of machine hand note the following four points:

First, carefully read the instruction manual machinery, master structure and properties, avoid gulping, opinionated and can not act as a "knowledgeable."

Second, farm sprayer operating machinery should follow the rules, pay attention to methods of maintenance and avoid so-so, not fooling.

Third, there is limited functionality agricultural machinery, truck speed limit regulations, avoid "small horse cart", Tanxiaoshida.

Fourth, the firm can not operate sick machinery, if it is found defective machinery, to immediately stop the operation, maintenance and repair promptly.

Cyclone

Cyclone is a rotational movement using fluid pressure generating means. When the slurry to a certain speed into cyclone, cyclone encounters the wall after being forced for rotary motion. Since the centrifugal force suffered different solids slurry of coarse particles suffered large centrifugal force, able to overcome the hydraulic resistance movement to the wall,water power sprayer  and in the joint action of its own gravity, spiral downward movement along the wall, thin and small granules and most of the water due to the centrifugal force suffered a small and less close to the wall that is to do with the slurry rotary motion. In the subsequent feeding, driven by continued downward slurry and rotary motion, then continue to the surrounding coarse particle concentration, while the small particles are stuck in the central area, particle size from the center to the wall increases, the formation of sub- layer arrangement.

As the slurry from the flow of the cylinder portion of the cyclone cone part, getting smaller and smaller flow cross-section,bottle sprayer the outer slurry contraction oppression, the inner layer contains a lot of small particles slurry had to change the table direction, turn upward movement, the formation of the inner cyclone, discharged from the overflow pipe to become overflow, while coarse particles continued to spiral downward movement along the wall, forming the outer cyclone, and ultimately by the underflow discharge port, a grit.

Liquid and dry sandblasting machine blasting machine difference

Function complete the clean liquid blasting stainless steel welded parts, heat treatment parts, stamping parts and machining parts rough surface, go residual salt and glitches for spraying, electroplating pretreatment process;
Liquid spray glass sandblasting machine also acts pills, strengthen polisher parts of the surface;
Liquid blasting machine is suitable for medium and small batch production of parts in a single piece, high quality and efficiency;
Liquid blasting machine is suitable for Table Factory, glasses factory, jewelry factory, electronics factory.
Siphon liquid blasting machine blasting,hand sprayer  the use of high-speed compression blasting produces a negative pressure flow ejector effect, the abrasive fluid tank through the hose suction and discharge of abrasive blasting gun, and then with the high-speed flow of compressed air from the nozzle blasting onto the workpiece surface, to sandblasting.
Liquid and conventional dry sand blasting machine are different, liquid abrasive blasting machine placed in the water, with the mill compressed air through the pump and the high-speed jet lance the grinding fluid workpiece surface to be machined, to the part surface cleaning and light decoration effect. Liquid sandblast machine high efficiency, garden hand sprayers abrasive consumption, to achieve improved surface finish and surface intensity. As a result of wet sandblasting machine liquid sealing operation, liquid abrasive grinding using water and natural sand (pill), but also a cycle work, so the work does not produce dust, does not emit toxic waste, no pollution to the environment produced equipment installation convenient and simple, does not require a separate workshop.
Box-type liquid blasting machine, blasting on mechanical parts, you can make the mechanical parts of the surface on the basis of the original increase of 0.5 to 2.0 finish, if we adopt a different pill material also allows mechanical parts to achieve light or matt effect. Liquid blasting is surface polishing, polishing one of the best ways.
