Banana frequency of application
Bananas with annual growth , rapid growth, large growth characteristics , and our climate is characterized by the best banana growing season hot and rainy weather occurs , after the fertilizer is easy to leakage, evaporation loss , therefore , must carry out the banana fertilization Qin Shi Shi thin , focusing on the period re-applied principle.
In recent years ,knapsack sprayer China's banana fertilization increased the number of prevalent than in the past , at least 5-9 times a year , as many as 10 to 20 times. How many times a year fertilization is appropriate then, it has been made a number of banana fertilization experiment , the first component 13 Shi , Shi eight times a second component , the same as the total amount of fertilizer . Results: The first group than the second group of plant stems 15 cm high , 2.7 cm thick ; first group of mid-August as a whole before pumping bud , before the beginning of the second set of nine group smoked ; production in the first group than the second group increased by 10% .
Fertilizer in multiple application, which can minimize wastage , improve efficiency, give full play to fertility. For sandy soil of banana plantations , fertilizers applied in multiple effect is more obvious.
Based on the above , we believe that the banana fertilization is more appropriate for the full year 12 times to 15 times , flower sprayer including heavy fertilizer five times , thin fat 7 to 10 times.

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.
