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...

Embodiment Construction

[0025] A method for preparing organic fertilizer for crops, using protein-rich animal raw materials, the specific steps are as follows:

[0026] crush

[0027] First coarsely pulverize, put into the pulverizer, and pulverize into block materials smaller than 4cm;

[0028] Then the bulk material is steamed and heated by steam, the steam temperature is 120 degrees, and the time is 5-10 minutes;

[0029] Then carry out fine pulverization, using a colloid mill to pulverize to 80 mesh-150 mesh, the speed of the colloid mill is 30-300 rpm, and the temperature during pulverization is ≤70 degrees;

[0030] Feed

[0031] The finely crushed fermentation material is fed from the bottom of the fermenter, using a fully sealed pipeline feeding method, the feed rate is 3-6 tons per hour, the temperature in the fermenter is 80 degrees, and the feeding amount is 20-40 tons; Water replenishment in the fermenter, the weight ratio of the water replenishment amount to the feed amount is 1~4:1; ...
