Embodiment 1
[0022] A method for preparing amino acid water-soluble fertilizer by leaves of neem, comprising the following steps:
[0023] (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;
[0024] (2) Add water with the same weight as the fermented neem leaves to the fermented neem leaves, stir for 2 hours, leaching, centrifuge, and collect the filtrate;
[0025] (3) Add sulfuric acid to the filtrate and hydrolyze it at 60°C for 15-22 hours to obtain the amino acid mother liquor;
[0026] (4) Testing and packaging to obtain the product. Wherein, the add-on of sulfuric acid is 10% of filtrate quality.
Embodiment 2
[0028] A method for preparing amino acid water-soluble fertilizer by leaves of neem, comprising the following steps:
[0029] (1) Stack 1 ton of neem leaves evenly, add 50kg of decomposing agent for fermentation, and the fermentation time is 7-10 days. If there is no foul smell, it means full fermentation;
[0030] (2) Add water with the same weight as the fermented neem leaves to the fermented neem leaves, stir for 1 hour, leaching, centrifuge, and collect the filtrate;
[0031] (3) Add hydrochloric acid to the filtrate and hydrolyze at 60°C for 15-22 hours to obtain the amino acid mother liquor;
[0032] (4) Testing and packaging to obtain the product. Wherein, the addition of hydrochloric acid is 12% of filtrate quality.
Embodiment 3
[0034] A method for preparing amino acid water-soluble fertilizer by leaves of neem, comprising the following steps:
[0035] (1) Stack 1 ton of neem leaves evenly, add 100kg of decomposing agent for fermentation treatment, the fermentation time is 7-10 days, if there is no foul smell, it means full fermentation;
[0036] (2) Add water with the same weight as the fermented neem leaves to the fermented neem leaves, stir for 0.5 hours, leaching, centrifuge, and collect the filtrate;
[0037] (3) Add nitric acid to the filtrate and hydrolyze it at 60°C for 15-22 hours to obtain the amino acid mother liquor;
[0038] (4) Testing and packaging to obtain the product. Wherein, the add-on of nitric acid is 8% of filtrate quality.

Abstract
The invention discloses a method for preparing an amino acid water-soluble fertilizer by nim leave, which solves the problem of poor prevention and treatment effect of current foliar fertilizers. The method comprises the following steps: 1) collecting and storing the nim leaves, adding a decomposition agent for full fermentation treatment; 2) adding water in the fermented nim leaves, stirring for 0.5-2 hours and leaching, and then centrifuging and collecting a filtrate; 3)adding strong acid in the filtrate and performing hydrolysis for 15-22 hours at the temperature of 40-80 DEG C to obtain an amino acidmother liquor; and 4)detecting and packaging to obtain the product. The water-soluble fertilizer provided in the invention has a plurality of biological activity such as insecticide and sterilization, has no harm to higher animal and is safe to natural enemy of insects, and the water-soluble fertilizer provided in the invention also has the advantage of no residue on plants.
Description
technical field [0001] The invention specifically relates to a method for preparing amino acid water-soluble fertilizer from neem leaves. 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 virusdisease 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 amino acid water-soluble fertilizer from neem leaves, so as to solve the problem that the existing foliage fertilizer has poor control effect. [0004] The present invention realizes through following technical scheme: [0005] A method for p...
