Embodiment 1

[0025] A preparation method of an amino acid water-soluble fertilizer containing polyaspartic acid, comprising the following steps:

[0026] (1) Stack 1 ton of neem leaves evenly, add 30kg of decomposing agent for fermentation, and the fermentation time is 7-10 days. If there is no foul smell, it means full fermentation;

[0027] (2) Add water of the same quality as the neem leaves to the fermented neem leaves, stir for 1-2 hours, leaching, centrifuge, and collect the filtrate;

[0028] (3) Add sulfuric acid to the filtrate and hydrolyze it at 60°C for 15-22 hours to obtain the amino acid mother liquor;

[0029] (4) Add raw materials containing copper, iron, manganese, zinc, boron, and molybdenum trace elements to the amino acid mother liquor (one or several types can be added, and adjusted according to the needs of different crops for trace elements), and then add polyaspartic acid in the reactor adequate chelation in

Abstract

The invention discloses a preparation method of an amino acid water-soluble fertilizer containing polyaspartic acid. The method solves the problem of poor prevention and treatment effect of current foliar fertilizer. The method comprises the following steps: 1) collecting and storing the nim leaves, adding a decomposition agent for fully fermenting and treating; 2) adding water in fermented nim leaves, stirring for 1-2 hours and leaching and then centrifuging, collecting a filtrate; 3) adding strong acid in the filtrate and hydrolyzing for 15-22 hours under the temperature of 40-80 DEG C to obtain an amino acid mother liquor; 4) adding trace elements and a conditioning agent in the amino acid mother liquor in a reaction vessel for fully chelating; and 5) detecting and packing to obtain the product. The amino acid water-soluble fertilizer containing polyaspartic acid has a plurality of biological activities such as insecticide and sterilization; has no harm to higher animal, is safe to natural enemy of insects, and has the advantage of no residues on plant.

Description

technical field [0001] The invention specifically relates to a preparation method of an amino acid water-soluble fertilizer containing polyaspartic acid. Background technique [0002] A variety of physiological diseases of different degrees occur to crops in our country every year, resulting in reduced yield and quality. Among them, tomato late blight and capsicum virus disease have not found effective control methods so far. Existing foliar fertilizers have poor control effects on these diseases. Therefore be necessary to develop a kind of foliage fertilizer that can prevent above-mentioned multiple diseases and improve yield and quality. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing an amino acid water-soluble fertilizer containing polyaspartic acid, so as to solve the problem that the existing foliar fertilizers have poor control effects. [0004] The present invention realizes through following technical...
