On the other hand, studies have shown that azadirachtin, the effective substance in neem leaves, is relatively stable in a solution with a pH of 4 to 6 at room temperature, but has poor stability in a strong acid solution and decomposes quickly. Finally, China Patent CN201310614659.1 only describes the neem leaf hydrolyzed amino acid fertilizer containing aspartic acid, which cannot meet the needs of various amino acids in the process of plant growth
The existing invention patent CN200710050593.2, although it is proposed to obtain amino acid active fertilizers by ultrafine crushing and enzymatic hydrolysis of distiller's grains, rapeseed meal, bean cake, straw, corn flour, bean curd residue, etc., but there is no specific method how to operate neem leaves Detailed Instructions for Obtaining Amino Acid Active Fertilizers

Abstract

The invention belongs to the field of an agricultural fertilizer, and concretely relates to a method for preparing an insect-resistant amino acid liquid fertilizer. The method comprises the followingsteps: (1) collecting the neem leaves and washing the neem leaves and taking a neem cake, performing low temperature refrigeration disinfection on the materials, sending the materials to an ultramicrocell disruption machine, and performing disruption to an ultra-micro-nano raw material with the particle size between 200nm-500nm; (2) uniformly mixing the ultra-micro-nano raw material and an aminoacid active inducing agent according to a weight ratio of 2:1 to prepare a semi-amino acid active raw material; (3) adding the semi-amino acid active raw material to the deionized water with 4-5 timesof weight, wherein the temperature is 30-40 DEG C, and a pH value is 5.5-6.5; (4) adding 2-4wt% of fermentation enzyme to the semi-amino acid active raw material, and performing enzymatic hydrolysisin a container for 36-48 hours to obtain the amino acid mother liquor; and (5) adding a trace element, free amino acid and an osmotic agent to the amino acid mother liquid to perform sufficient chelation in a reaction vessel to obtain the amino acid liquid fertilizer. The fertilizer can effectively kill pests and diseases, increase plant resistance and increase crop yield, and the field experimentcan increase the yield of capsicum by more than 30%.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a method for preparing an insect-resistant amino acid liquid fertilizer. Background technique [0002] Due to the long-term use of chemical fertilizers in farmland, soil compaction, water pollution, endangering people's health, and the vigorous development of modern green agriculture and organic agriculture, therefore, all countries in the world are developing and using various natural fertilizers to reduce the impact of chemical fertilizers on the ecology. Environmental hazards, maintaining agricultural ecological balance. [0003] Medicinal fertilizer is a functional fertilizer that has one or more functions of killing and inhibiting crop diseases and insect pests or crop growth regulation, and can provide nutrition for crops or at the same time provide nutrition and improve the utilization rate of fertilizers and pesticides. Fertilizer and pesticide experts at home and...
