Composite amino acid chelated trace element water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a composite amino acid chelated trace element water-soluble fertilizer and a preparation method thereof. The fertilizer comprises the following raw materials in parts by weight: 300 to 500 parts of composite amino acid water solution, 30 to 50 parts of potassium selenite, 20 to 30 parts of iron oxide, 10 to 20 parts of zinc oxide, 5 to 15 parts of boric acid, 5 to 10 parts of copper carbonate, 20 to 30 parts of manganese carbonate, 5 to 10 parts of sodium molybdate, and 400 to 800 parts of water. The preparation method comprises the following steps: mixing and heating raw materials, stirring, filtering, cooling, carrying out chelating reactions and composite reactions, concentrating the reaction product, drying, examining, and packaging. The trace component of the fertilizer is synthesized according to the formula; and the trace component can be individually used or compounded with other fertilizers to satisfy the needs of plants. The provided composite amino acid chelated trace element water-soluble fertilizer has the characteristics of instant property, long-lasting fertilizing effect, comprehensive nutrients, stable chelating, strong chelating performance, easy absorption for plants, harmlessness, and uniform release of nutrients.

Description

technical field [0001] The invention relates to a compound water-soluble fertilizer, in particular to a compound amino acid chelated trace element water-soluble fertilizer and a preparation method thereof, belonging to the technical field of agricultural chemical fertilizers. Background technique [0002] According to the research of our country's scientific research department, amino acid peptides are essential nutrients for animals and plants. They are used as chelating agents for research, development and application. The absorption rate of amino acid chelated trace elements to crops is 2 to 6 times that of inorganic salts, which is higher than that of inorganic salts. Has greater and superior universal absorption and digestion and metabolism. It can effectively increase the growth rate, reduce fertilizer consumption, and increase crop resistance to disease. [0003] As a new type of fertilizer, water-soluble fertilizer, compared with traditional fertilizers, not only ha...

AI Technical Summary

Problems solved by technology

[0008] 1) In the existing technology, the preparation of amino acid chelated water-soluble fertilizer is simply mixing raw materials, only through heating, stirring, impurity removal and drying, and there is no strict process route, and the control conditions are not strict enough, which makes the product The content of effective elements in the product is reduced, and the active ingredients cannot be effectively preserved

When used in production, plants cannot be effectively absorbed, resulting in low plant absorption and utilization, and even a lack of required elements, making plants unable to grow normally;

[0009] 2) In the prior art, selenium is rarely contained in conventional trace element fertilizers, but selenium has a greater impact on crop growth, especially for selenium-accumulating plants. When selenium is lacking, the normal growth of plants is affected

In the process of agricultural production, when selenium is needed, selenium is generally used as a separate fertilizer, which is cumbersome and difficult to control the amount of use
