Preparation method of cornifin amino acid fertilizer

Abstract

The invention relates to the technical field of production of fertilizers, and particularly discloses a preparation method of a cornifin amino acid fertilizer. The preparation method of the cornifin amino acid fertilizer uses waste hairs as raw materials, and is characterized by comprising the following steps of (1) putting water into a reaction kettle, and heating; (2) stirring the heated water, adding an alkaline liquid, and uniformly mixing; (3) adding the waste hairs into the thinned alkaline liquid at uniform speed, stirring at constant temperature, chelating, completely decomposing, and converting into an amino acid liquid; (4) adding a pH (potential of hydrogen) regulating agent into the amino acid liquid, draining the amino acid liquid out of the reaction kettle, filtering and cooling, so as to obtain an amino acid liquid fertilizer. The preparation method has the advantages that the required equipment is simple, the operation technique can be easily controlled, the source of raw materials is enough, the investment is little, the demand amount is large, and the social and economic benefits are good; the pH value of soil can be effectively regulated, and the acid soil can be well improved.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of fertilizer production, in particular to a preparation method of keratin protein amino acid fertilizer. [0003] (2) Background technology [0004] In the process of plant growth, amino acids have the function of replenishing organic nitrogen nutrients, chelating metal ions, promoting and catalyzing the synthesis of various enzymes in plants, and because amino acids can be passively and directly absorbed by plants, they provide animals and plants with great Good nutrition has been paid more and more attention by human beings. The main component of hair is protein, which can be hydrolyzed into polypeptides, which can be further hydrolyzed into about 17 kinds of amino acids. Human and animal hairs are rich in sources in daily life. How to effectively use these resources is a problem worthy of widespread attention. [0005] At present, there are many preparation methods for amino acids, but the mai...

Problems solved by technology

[0005] At present, there are many preparation methods for amino acids, but the main disadvantage is that the cost of protein raw materials currently on the market is relatively high, which increases the cost of animal and plant products; secondly, the utilization rate of amino acids after hydrolysis is very low in the prior art. Low, the product consumption is relatively large; in addition, the existing production of free amino acid technology has a large amount of pollutant discharge, which seriously pollutes the environment. At the same time, only a few percent of amino acid chelated elements are used in domestic planting and breeding industries, and its development prospects are broad.
