Water-soluble amino acid fertilizer and preparation method thereof

Abstract

The invention provides water-soluble amino acid fertilizer and a preparation method thereof. Raw materials of the water-soluble amino acid fertilizer comprise one or a mixture of bone meal, soybean cakes, rice bran, wheat bran, fish and shrimps. According to the water-soluble amino acid fertilizer, protein waste is used sufficiently, waste is changed into wealth, reaction conditions in a preparation process are mild, amino acid deterioration is avoided, and a racemization effect is not produced. Meanwhile, by the aid of a microbial fermentation technology, soil is conditioned, microorganisms in the soil are activated, soil hardening is avoided, and the air permeability of the soil is improved. Drought pressure of the soil can be relieved, use of chemical fertilizer can be reduced, damage of salt and alkali to the soil can be reduced, and the soil fertility can be improved. Meanwhile, the yield of food crops, cash crops, vegetables, melons and fruits can be increased greatly.

Description

technical field [0001] The invention relates to a fertilizer, more specifically to an amino acid water-soluble fertilizer and a preparation method thereof. Background technique [0002] Amino acid is a class of organic compounds containing amino and carboxyl groups. It is the basic unit of protein. It has complexation ability and can form relatively stable complexes with metal complexes. important raw material for fertilizers. At present, a large amount of protein waste in our country is not fully utilized, and using protein waste to produce amino acid fertilizer is one of the ways to turn waste into treasure. [0003] Most of the amino acid fertilizers produced by existing enterprises use acid hydrolyzed proteins to prepare amino acids, such as amino acids produced by hydrolysis of plant protein bean dregs, oily feet, and hair with concentrated sulfuric acid (application number: 03111654.X), or hydrolysis of keratin in hair with hydrochloric acid Preparation of amino acid...

AI Technical Summary

Problems solved by technology

The amino acid aqueous solution prepared by acid hydrolysis above contains a large amount of acid, which requires a relatively complicated acid removal process in the follow-up, and the economic cost is relatively high

However, the amino acids produced by alkali hydrolysis of protein will be damaged to varying degrees and cause racemization, and the hydrolysis rate of protein is low, and the excess alkali needs to be neutralized in the follow-up, which increases economic costs.
