Embodiment 1

[0016] The process of producing organic fertilizer by decomposing livestock and poultry manure is as follows:

[0017] ①. Dehydrate and dry the livestock and poultry manure and straw separately, pulverize to a particle size of 0.5-0.8mm, and mix the mixture at a weight ratio of 5.5:2.

[0018] ②. According to the weight ratio of the mixture to the decomposing fungus, the ratio is 7500:2, and the decomposing fungus is mixed. The decomposing fungus contains cellulase, hemicellulase and lignin in a mass ratio of 1:1.5:1.5:0.5. Enzymes and proteases. Add water to a water content of 32%, and ferment at a high temperature of 54°C for 7 days.

[0019] ③. Prepare powder or granule organic fertilizer according to the existing technology.

Embodiment 2

[0021] The process of producing organic fertilizer by decomposing livestock and poultry manure is as follows:

[0022] ①. Dehydrate and dry the livestock and poultry manure and straw separately, pulverize to a particle size of 0.8-1.3mm, and mix the mixture at a weight ratio of 8:1.

[0023] ②. According to the weight ratio of the mixture and the decomposing fungus, the ratio is 12000:2, and the decomposing fungus is mixed, and the decomposing fungus contains cellulase, hemicellulase and lignin with a mass ratio of 2:1.5:0.7:1.5. Enzymes and proteases. Add water to 30% water content and ferment at 52°C for 6 days.

[0024] ③. Prepare powder or granule organic fertilizer according to the existing technology.

Embodiment 3

[0026] The process of producing organic fertilizer by decomposing livestock and poultry manure is as follows:

[0027] ①. Dehydrate and dry the livestock and poultry manure and straw separately, crush them to a particle size of 1.3~1.7mm, and mix them at a weight ratio of 5.5:1 to obtain a mixture.

[0028] ②. According to the weight ratio of the mixture and the decomposing fungus, the ratio is 7500: 1.5, and the decomposing fungus is mixed, and the decomposing fungus contains cellulase, hemicellulase and lignin with a mass ratio of 2.5: 1.5: 1.5: 0.8. Enzymes and proteases. Add water to a water content of 30.5%, and ferment at a high temperature of 53°C for 5 days.

[0029] ③. Prepare powder or granule organic fertilizer according to the existing technology.

Abstract

The invention belongs to the field of organic fertilizer production, and in particular relates to a process for producing an organic fertilizer by livestock and poultry manure composting. According to the principle of high-temperature composting, composting is a process that organic matters are mineralized, humified and decontaminated into compost fertilizer by high temperature fermentation under the effect of microorganisms; in the process of organic matter decomposition by microorganisms, a large amount of effective nitrogen, phosphorus and potassium compounds capable of being absorbed and utilized by crops are generated, and a new organic polymer humus is synthesized, which is an important active material forming soil fertility. According to invention, livestock and poultry manure is used as a main raw material, added with an appropriate amount of filling materials (such as a straw powder) and inoculated with a humus microbial inoculum, so as to complete high temperature fermentation of the compost in a short time, and realize harmlessness and recycling. The process can produce a biological organic fertilizer needed by agriculture and crop farming, as well as solve the problem of environment pollution caused by livestock and poultry manure.

Description

Technical field [0001] The invention belongs to the field of organic fertilizer production, and specifically relates to a process for producing organic fertilizer by decomposing livestock and poultry manure. Background technique [0002] In recent years, with the implementation of the "vegetable basket" project in various places, large-scale farms have developed rapidly, producing large amounts of livestock and poultry manure. Poultry breeding pollution has become the main source of agricultural non-point source pollution, and pollution control and resource utilization of livestock and poultry breeding have become urgent. In response to the pollution of livestock and poultry farms, the State Environmental Protection Administration promulgated the "Management Measures for Pollution Prevention and Control of Livestock and Poultry Breeding" (State Environmental Protection Administration Order No. 9) in 2001, and issued a supporting "Pollutant Discharge Standard for Livestock and Pou...
