Preparation method of crop organic fertilizer

Abstract

The invention discloses a preparation method of a crop organic fertilizer. The crop organic fertilizer is prepared by coarsely crushing, cooking and finely crushing a protein-rich animal body such as mackerels of the marine fishery as a raw material through an enzymolysis and fermentation process; the reaction principle is as follows: microorganisms and enzyme preparations are subjected to a biological fermentation reaction, protein components contained in the raw material fish are decomposed into micromolecular amino acid polypeptide components, thereby facilitating plant absorption and utilization and propagating beneficial bacteria so as to achieve good effects. The crop organic fertilizer is rich in natural active materials and free of artificially synthesized hormones, has the characteristics of recycling, safety, no pollution and no residual harmful substance, contains rich protein, amino acid and mineral substances and is an excellent agricultural nitrogen element source and an animal feed protein and small peptide source.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a method for preparing an organic fertilizer for crops. Background technique [0002] Using fish and other marine resources (generally waste, processing leftovers) as the main body, adding molasses, fiber, etc., to fertilize has existed in ancient times. Later, more modern methods were also used to produce fish fertilizers, but single treatment was often used Methods, such as the production of fertilizer products by enzymatic hydrolysis alone, or the production of products by acid hydrolysis alone, are not produced in a combination of multiple methods. [0003] For example, the patent application number: 201110061604.3, the process of making bio-organic fertilizer from fish, using fish leftovers and fermentation method to produce organic fertilizer. Application number: 201310555488.X is a method for producing amino acid agricultural fertilizers by hydrolyzing fish skin and scales with c...

Problems solved by technology

Chemical hydrolysis with strong acid and strong alkali is fast, but it requires high temperature and high pressure conditions, high equipment requirements, and inevitably causes some amino acids to be destroyed or racemized, reducing the utilization rate of active ingredients; using enzyme hydrolysis Protein, with mild conditions, avoids corrosion and damage to production machinery and equipment, but the degradation efficiency is poor, and the protein cannot be completely degraded into amino acids, and the degree of hydrolysis is low; the cost of protein degradation by fermentation is low, and it can also use microbial growth. Additional beneficial ingredients, but it takes a long time and the control conditions (temperature, ventilation) are strict
