Embodiment 1
[0027] (1) Preparation of cuproammonia solution
[0028] Add 25 parts of copper sulfate and 35 parts of ammonium bicarbonate to 40 parts of water, heat and stir at 70°C to react, release carbon dioxide gas, dissolve and cool to form cuproammonia solution, containing about 7.5% copper, sample and analyze for later use;
[0029] (2) Preparation of nutritional copper fungicide: get 40Kg copper ammonia solution, add zinc sulfate 3kg, manganese sulfate 3kg, citric acid 3kg, ethylenediaminetetraacetic acid (EDTA) 5kg, borax 3kg, ammonium ferrous sulfate under stirring 0.5kg, sodium molybdate 0.2kg, stir to disperse evenly, slowly add ethylenediamine 5kg, the reaction is exothermic, and stir for more than 30 minutes. After the chelation is completely dissolved, add 0.8kg of AES ammonium surfactant, 0.5kg of naphthaleneacetic acid, and 36kg of water under stirring, stir evenly, and take samples for inspection to obtain a nutritional copper bactericide.
Embodiment 2
[0031] (1) Preparation of cuproammonia solution
[0032] Add 25 parts of copper sulfate to 20 parts of water, add about 60 parts of 26% ammonia water dropwise under stirring, until the pH value reaches 10.5-11.0, and it is in a completely dissolved state to obtain a copper ammonia solution. Contains about 6.2% copper, sample and analyze for future use;
[0033] (2) Preparation of nutritional copper fungicide: Take the above 60kg cuproammonia solution, add 4kg of zinc nitrate, 3kg of manganese sulfate, 2.5kg of citric acid, 5kg of ethylenediaminetetraacetic acid (EDTA), 4kg of borax, and sulfite under stirring. Iron 0.4kg, sodium molybdate 0.1kg, stir evenly, slowly add ethylenediamine 4kg, reaction exotherm, stir for more than 30 minutes. After the chelation is complete, add 0.8kg of Tween-80 surfactant under stirring, add 0.5kg of sodium nitrophenolate, add 15.7kg of water to a total of 100kg, stir evenly, and take samples for inspection to obtain a nutritional copper fungic...
Embodiment 3
[0035] (1) Preparation of cuproammonia solution
[0036] Add 23 parts of copper nitrate to 22 parts of water, add about 60 parts of 26% ammonia water dropwise under stirring, until the pH value reaches 10.5-11.0, and it is in a completely dissolved state to obtain a copper ammonia solution. Copper content is about 5.9%, sample analysis for future use;
[0037] (2) Preparation of nutritional copper fungicide: take the above 64kg cuproammonia solution, add 2kg of zinc sulfate, 3.0kg of manganese nitrate, 4kg of citric acid, 5kg of ethylenediaminetetraacetic acid (EDTA), ethylenediamine dioxane under stirring Sodium hydroxyphenyl macroacetate (EDDHANa) 2kg, boric acid 4kg, ferrous sulfate 1.5kg, ammonium molybdate 0.5kg, stir evenly, slowly add ethylenediamine 9kg, reaction exotherm, stir for more than 30 minutes. After the chelation is complete, add 1.0kg of OP-10 surfactant under stirring, add DA-61.5kg, add water 2.5kg to a total amount of 100kg, stir evenly, and take a sampl...
