Abstract

The invention provides a production method of a bacterial spawn for efficient composting. The production method of the bacterial spawn for efficient composting comprises the following steps: efficientcomposting compound microbial agent compounding, raw material fermentation and bacterial spawn preparation. Fermentation raw materials comprise 35-45% of fungus chaff, 15-20% of coconut residues, 10-20% of cinnamomum camphora sawdust, 5-10% of bran, 5-15% of fly maggot manure, 10-15% of coffee grounds and 2-3% of lemon grass. The compost compound microbial agent is a compound microbial agent of protein decomposition bacteria, cellulose decomposition bacteria, lignin decomposition bacteria and compost special extraction bacteria. According to the bacterial spawn for efficient composting, nutritional ingredients of the organic solid waste are effectively utilized for enrichment culture of the microbial agent, the high-density bacterial spawn for composting is obtained, the ecological and environment-friendly effects are achieved, the production process of the bacterial spawn is effectively simplified, the composting efficiency and economic benefits are greatly improved, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of composting, in particular to a production method of bacteria bricks for high-efficiency composting. Background technique [0002] With the development of human society and the advancement of science and technology, people are increasingly aware of the importance of resources and the environment to human beings. The potential utilization value of organic solid waste has also begun to be recognized by people, not only because it contains a large amount of energy substances (carbon), but also because it is rich in nutrients (nitrogen, phosphorus, potassium and trace elements) required by crops . The composting process is part of the ecological process on the earth's surface. The litter, weeds, bark and other organic matter remaining on the earth's surface are continuously decomposed and then further participate in the cycle of matter and energy. Modern composting is the conversion of organic solid waste (i...
