Static excrement fermentation method for small and medium-sized livestock and poultry farms

Abstract

The invention relates to the field of livestock and poultry excrement fermentation, in particular to a static excrement fermentation method for small and medium-sized livestock and poultry farms. The method comprises the steps that the area of a static fermentation greenhouse is determined according to the cultivation scale; fermentation strain and auxiliary materials are prepared; the auxiliary materials comprise crop stalks, rice straw and the like; layer-to-layer stacking and fermentation are carried out on livestock and poultry excrement and the auxiliary materials; the temperature starts to be increased 2-3 days after the materials are stacked and fermented, and the temperature can reach more than 60 DEG C; the materials tend to become thoroughly decomposed after 25-30 days of static fermentation, some discharged materials can be recycled to be used as auxiliary materials to reduce consumption of new auxiliary materials, and the rest of discharged materials can be used as fertilizer for selling or agricultural utilization. The method has the advantages that the process is simple, operation is convenient, the labor intensity is low, investment is low, and the processing efficiency is high.

Description

technical field [0001] The invention relates to the field of livestock and poultry manure fermentation, in particular to a method for static fermentation of manure from small and medium-sized livestock and poultry farms. Background technique [0002] The environmental problems caused by the large amount of livestock and poultry manure discharged from intensive and large-scale livestock and poultry farms have attracted widespread attention from all walks of life. How to realize the effective treatment and disposal of livestock and poultry manure has become an important environmental protection problem that urgently needs to be solved in current livestock and poultry farms. one. Livestock and poultry manure itself is a valuable resource. Manure contains a large amount of cellulose and hemicellulose, which can provide the carbon source needed for microbial growth. In addition, it also contains a small amount of protein, fat, organic acid, nitrogen, and phosphorus. , Potassium ...

Problems solved by technology

Straw, rice straw and other materials are by-products of various economic crops. In the past, most of them were burned and returned to the field. However, burning straw will cause serious air pollution and harm. Many areas have explicitly banned straw burning. Therefore, many areas A large amount of waste straw has been piled up, which is not only a waste of resources, but also causes certain environmental pollution
