Problems solved by technology

[0004] In the past, control personnel usually used industrial-grade phosphorous acid and potassium hydroxide dissolved in water at a ratio of 1:1; dissolving phosphorous acid in water first, and then dissolving potassium hydroxide was not only time-consuming and labor-intensive, but the prepared phosphorous acid solution , limited to one-day use, the above operations are not only cumbersome, but also for many farmers who do not have certain knowledge of chemical synthesis, it is often easy to misuse it, resulting in failure of the efficacy of the medicine and fertilizer, and even causing adverse effects on their own skin

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.

Abstract

The invention discloses a plant immunizing agent containing phosphorous acid and copper ions and a preparation method of the plant immunizing agent. The plant immunizing agent is prepared from the following raw materials in parts by mass: 3 to 5 parts of water, 0.1 to 0.5 part of copper salt, 2 to 4 parts of phosphorous acid, 1 to 2 parts of compound sugar alcohol, 0.5 to 1.5 parts of potassium hydroxide solution and a chelating agent. The mass fraction of the chelating agent is the same with that of the copper salt. Phosphorous acid, potassium, copper, zinc, boron and other elements are adopted, nutrition requirements of various crops in the growth process can be effectively met, crop diseases and insect pests such as citrus ulcer, pitaya ulcer, kiwi fruit ulcer and gummosis of peach trees and pear trees and root rot and stem rot of tomatoes, peppers, flowers and the like caused by bacterial infection, fungal infection and the like can be more effectively prevented and treated through combination of phosphorous acid and copper ions, and the plant immunizing agent is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a plant immune agent containing phosphorous acid and copper ions and a preparation method thereof. Background technique [0002] The planting of new economic crops is becoming more and more popular, but the excessive pesticide residues caused by the use of pesticides for pest control have increasingly become the focus of attention on the table of ordinary people. [0003] Phosphorous acid is the main raw material of a new type of non-pesticide control that is being vigorously promoted and used in developed countries. Phosphorous acid (KH 2 PO 3 ) was applied to crop disease prevention. It originated from the successful research and development of a disease-prevention drug "Forsaide" in the 1980s. It was found that the main disease-inhibiting substance was phosphorous acid in its metabolites, which could stimulate the host plant to activate the defense system and produce Anti...
