Solid fermentation substrate

Abstract

The invention discloses a solid fermentation base applicable to the treatment of human, chicken, pig, cow and sheep excrement, crop straw and other solid organic waste for producing high-efficiency organic manure. Cultured solid bacteria agent is aired in an aseptic ventilating place; according to bacteria mixture ratio in percentage by weight, 32 percent of bacillus subtilis, 22 percent of bacillus licheniformis, 25 percent of bacillus megaterium, 7 percent of aspergillus oryzae and 14 percent of Absidia corymbifera are mixed into the solid fermentation base. As the solid fermentation base is added to livestock-poultry excrement, crop straw and other compost raw materials of which the moisture content and carbon nitrogen ratio are well regulated, aerobic microorganism in the raw materials can grow and reproduce fast, so as to rapidly raise the temperature of compost, shorten the fermentation period of the compost and realize harmless treatment; organic matter is transformed into a large amount of humic acid so as to raise the stability degree of the compost, which is beneficial to soil improvement, raises the crop yield and the quality, and reduces environmental pollution.

Description

Technical field: [0001] The invention relates to a solid fermentation base suitable for processing solid organic wastes such as human, chicken, pig, cow, sheep manure and crop stalks to produce high-efficiency organic fertilizer. Background technique: [0002] With the rapid development of intensive agriculture in our country, a large amount of agricultural solid organic waste is wasted, incineration of wheat, corn, rice, rapeseed and other crop stalks, and large-scale livestock and poultry manure dumped anywhere not only seriously pollute the environment , Also greatly wasted the raw material of these organic fertilizer products. The only way to maximize the return of the nutrients taken from the soil by harvesting crops to the soil is through the application of organic fertilizers produced from livestock and poultry manure and crop stalks. The traditional organic fertilizer production process is to use the microorganisms contained in the raw materials to carry out aerobic...

AI Technical Summary

Problems solved by technology

Due to the limited number and types of microorganisms in the material and the low microbial activity, the temperature of the organic material rises slowly, the high temperature is not high, and the duration of the high temperature is short, so that the organic materials such as livestock manure and crop straw are harmless and stable. Therefore, the quality of the organic fertilizer produced is not high, the production cycle is long, and the production cost is high, so that the organic fertilizer production enterprises are always on the verge of losing money

Moreover, a large amount of odor is often produced during the production process, causing secondary pollution.
