Problems solved by technology

However, the composition has higher requirements for compatible water-soluble fertilizers, and there are technical limitations on the compatibility of DMPP with trace elements such as calcium, magnesium, zinc, and manganese; the survival of Bacillus subtilis and Bacillus coli Value and acidity and alkalinity, etc. have high requirements, which makes the addition and application of the composition in water-soluble fertilizers limited.

Abstract

The invention discloses a fertilizer synergist, which is composed of a functional additive and a balance stabilizer with the mass ratio being 1:1, wherein the functional additive is prepared from acetyl-thiazolidine-4-carboxylic acid and DCPTA, the balance stabilizer is composed of potassium acetate and potassium citrate, the mass ratio of acetyl-thiazolidine-4-carboxylic acid to potassium acetateis 1:1, the mass ratio of DCPTA to potassium citrate is 1:1, the mass fraction of acetyl-thiazolidine-4-carboxylic acid in the fertilizer synergist is 5-20%, and the mass fraction of DCPTA in the fertilizer synergist is 30-45%. The invention also discloses a preparation method of the fertilizer synergist. The preparation method comprises the steps of 1) mixing the acetyl-thiazolidine-4-carboxylicacid and the potassium acetate, crushing and sieving; 2) mixing DCPTA and potassium citrate, crushing and sieving; and 3) uniformly mixing the two solid phases to obtain the fertilizer synergist. Thefertilizer synergist can effectively promote the absorption and utilization of crops on nutrient elements, can be stably compounded with a water-soluble fertilizer containing macroelements, medium elements and microelements, does not contain an organic solvent in the preparation process, and has the advantages of greenness, high efficiency, no residue and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a fertilizer synergist and its preparation method and application. Background technique [0002] With the development of my country's water-saving agriculture and water-fertilizer integration technology, water-soluble fertilizers have gradually received attention. As a new type of fertilizer that meets the needs of integrated water and fertilizer fertilization, the development of water-soluble fertilizers meets the needs of the sustainable and rapid development of modern agriculture in my country. [0003] The existing research results show that the research on fertilizer synergists mainly focuses on "nitrogen fertilizer synergists" such as urease inhibitors, nitrification inhibitors, and ammonia stabilizers. Gradually, functional substances are also compounded as fertilizer synergists. matching research. For example: the invention patent "nitrogen fertilizer synergist comp...
