Organic fertilizer process

Abstract

The invention discloses an organic fertilizer process, which comprises: S1, raw material pretreatment: selecting crop straws, chicken manure and pig manure as main raw materials, carrying out solid-liquid separation on the chicken manure and the pig manure, weighing, dividing, dewatering the straws, and crushing; S2: stirring: stirring the crop straws, the chicken manure and the pig manure, addinga strain, continuously stirring, and carrying out primary composting fermentation on the stirred raw materials; and S3: secondary fermentation: shoveling the fermented raw materials obtained in the step S2 into a fermentation groove by using a forklift, carrying out secondary fermentation, and turning the raw materials by a composting heap turner every day. According to the present invention, bydetermining the effective viable bacterial number, the organic matter, the moisture content, the organic nitrogen, the phosphorus content, the potassium content and the heavy metal content in the organic fertilizer, the quality of the organic fertilizer can be accurately understood, and the quality can be conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer process. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals. They are applied to the soil to provide plant nutrition as carbon-containing materials. They are processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. Substances, rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, not only can provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and update soil organic matter , to promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, is the main nutrient for the production of green food, so the preparation process of organ...

[0002] Organic fertilizers are mainly derived from plants and (or) animals. They are applied to the soil to provide plant nutrition as carbon-containing materials. They are processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. Substances, rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, not only can provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and update soil organic matter , to promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, is the main nutrient for the production of green food, so the preparation process of organic fertilizer is getting more and more attention, the patent document of retrieval application number 201110094556.8 discloses the process of producing organic fertilizer from wheat bran , Key points of the technical plan: chemically react ammonium sulfite and wheat bran under high temperature and high pressure to dissolve and extract the lignin in the wheat bran, and send it into the fertilizer production line as a whole to produce organic fertilizer or organic fertilizer rich in ammonium lignosulfonate. Inorganic compound fertilizer, compared with the conventional decomposing method, under the same yield, the time is shortened by 98%, and the land occupation is reduced by 95%. Potassium utilization rate, especially the utilization rate of phosphorus is obvious, reducing the amount of fertilizer, reducing surface pollution of water bodies caused by agricultural fertilization, increasing crop yield, reducing agricultural production costs, improving soil aggregate structure, and combining land use and land cultivation. Effects and properties: The fertilizer is very easy to deliquescence, with a pH value of 5.5-7, neutral and slightly acidic, but this organic fertilizer process is not convenient for testing organic fertilizers, and it is not convenient for controlling the quality of organic fertilizers
