Preparation method of suspension liquid water-soluble fertilizer with amino acids, calcium and magnesium

Abstract

The invention provides a preparation method of a suspension liquid water-soluble fertilizer with amino acids, calcium and magnesium. The method comprises the following steps: (1) respectively preparing a mixed solution A and a mixed solution B in advance, adding raw materials according to a ratio, and stirring while adding the raw materials, wherein the mixed solution A is prepared from calcium nitrate, water, ammonium polyphosphate and an amino acid plant nutrient solution; the mixed solution B is prepared from magnesium sulfate, water, urea, potassium pyrophosphate and the amino acid plant nutrient solution; and (2) adding the mixed liquid A and the mixed liquid B into a liquid shearing machine, circularly emulsifying, successively adding a stabilizer and a penetrant while emulsifying, continuously emulsifying for 10-30 minutes, adding potassium hydroxide for adjusting to a proper pH value to form a mixed solution C, cooling, filtering and filling the mixed solution to form the suspension liquid water-soluble fertilizer. After the suspension liquid water-soluble fertilizer is subjected to double chelation of the amino acid plant nutrient solution and ammonium polyphosphate, calcium and magnesium elements in the product are not easily regulated by the soil; the suspension liquid water-soluble fertilizer is easily absorbed; the nutrient utilization rate is increased; the suspension liquid water-soluble fertilizer is capable of directionally complementing the calcium and magnesium elements and improving stress resistance and photosynthetic capacity of the crops.

Description

technical field [0001] The invention belongs to the field of amino acid water-soluble fertilizer production, and in particular relates to a preparation method of amino acid calcium and magnesium suspension liquid water-soluble fertilizer. Background technique [0002] In the context of modern agriculture, increasing crop yield, improving product quality, improving fertilizer utilization rate, balancing fertilization, and improving and repairing soil are the goals that are constantly pursued. The current soil level will limit the development of agriculture more extensively. The ratio of nitrogen, phosphorus, and potassium Unreasonable and variety structure, low utilization rate of chemical fertilizers, especially the lack of medium and trace elements have become the main limiting factors restricting the improvement of crop yield and quality, so the development and promotion of corresponding fertilizers have increasingly attracted people's attention and attention.

[0002] In the context of modern agriculture, increasing crop yield, improving product quality, improving fertilizer utilization rate, balancing fertilization, and improving and repairing soil are the goals that are constantly pursued. The current soil level will limit the development of agriculture more extensively. The ratio of nitrogen, phosphorus, and potassium Unreasonable and variety structure, low utilization rate of chemical fertilizers, especially the lack of medium and trace elements have become the main limiting factors restricting the improvement of crop yield and quality, so the development and promotion of corresponding fertilizers have increasingly attracted people's attention and attention

[0003] With the continuous promotion of the market, products related to water-soluble fertilizers with medium and trace elements emerge in endlessly in my country, but the effect of the products varies greatly

In particular, the calcium and magnesium type water-soluble fertilizer products with medium elements are insufficient in content, low utilization rate, unstable form, and large amount of water-insoluble substances in the product, which affect the effect of the product, and even precipitate and stratify.

Calcium and magnesium ions are easy to form precipitation or crystallization with phosphate and sulfate, which greatly affects the use effect and commerciality, and does not really serve the purpose of supplementing the missing elements
