Embodiment 1
[0033] A preparation method of a plant immune agent containing phosphorous acid and copper ions, comprising the following steps:
[0034] (1) Put 4 parts of water in the reaction kettle, dissolve 0.5 parts of copper hydroxide, 0.35 parts of zinc hydroxide, and 0.15 parts of borax. During the dissolution process, add 0.85 parts of EDTA to make the copper ions into a chelated state, that is, EDTA copper;
[0035] (2) Slowly put 2 parts of phosphorous acid and 1 part of complex sugar alcohol (mannitol + sorbitol) into the reaction kettle while stirring, dissolve evenly and stabilize the product structure;
[0036] (3) Finally, while stirring in the reactor, slowly add 1 part of 50% potassium hydroxide solution. Note that a large amount of heat will be released during the process, and a large amount of water vapor will be released. This part of water vapor can be recovered by the reactor cooling recovery device; the solution is completely After cooling, a plant immune agent conta...
Embodiment 2
[0039] A preparation method of a plant immune agent containing phosphorous acid and copper ions, comprising the following steps:
[0040] (1) Put 4 parts of water in the reaction kettle, dissolve 0.35 parts of copper sulfate, 0.35 parts of zinc sulfate, 0.15 parts of borax, add 0.2 parts of citric acid, and 0.5 parts of EDTA to make the copper and zinc ions into a chelated state, that is, citric acid copper zinc;
[0041] (2) Slowly put 3.5 parts of phosphorous acid and 1 part of complex sugar alcohol (mannitol + sorbitol) into the reaction kettle while stirring to dissolve evenly and stabilize the product structure;
[0042] (3) Finally, while stirring in the reactor, slowly add 2 parts of 50% potassium hydroxide solution. Note that a large amount of heat will be released in the process and a large amount of water vapor will be released. This part of water vapor can be recovered by the reactor cooling recovery device; the solution is completely After cooling, a plant immune ...
Embodiment 3
[0044] A preparation method of a plant immune agent containing phosphorous acid and copper ions, comprising the following steps:
[0045] (1) Throw 4 parts of water in the reaction kettle, dissolve 0.1 part of copper sulfate, add 0.1 part of citric acid, and make the copper ion into a chelated state, i.e. copper citrate;
[0046] (2) Slowly put 3.5 parts of phosphorous acid and 1 part of complex sugar alcohol (mannitol + sorbitol) into the reaction kettle while stirring to dissolve evenly and stabilize the product structure;
[0047] (3) Finally, while stirring in the reactor, slowly add 2 parts of 50% potassium hydroxide solution. Note that a large amount of heat will be released in the process and a large amount of water vapor will be released. This part of water vapor can be recovered by the reactor cooling recovery device; the solution is completely After cooling, a plant immune agent containing phosphorous acid and copper ions can be obtained.
