Method for producing straw decomposition agent by utilizing filter mud, cassava residues and waste alcohol mash

Abstract

The invention provides a method for producing a straw decomposition agent by utilizing filter mud, cassava residues and waste alcohol mash. The method is characterized by mixing filter mud, cassava residues and bagasse ash in a weight ratio of (3-4):(3-4):(1-2), then adding a microorganism thallus prepared from bacillus subtilis Cohn, bacillus licheniformis, bacillus polymyxa, aspergillus niger and aspergillus oryzae and mixing the materials uniformly, fermenting the mixture for 5-10 days, and then grinding and drying the fermented product at low temperature, thus obtaining the straw decomposition agent. Used for producing the straw decomposition agent, the method has the advantages of low production cost, high viable organism amount and obvious decomposing effect and can be used for decomposing objects such as banana cores, corn straws, wheat straws, rice straws, cereal straws, rape straws, weeds, leaves, household garbage with high content of fibrous matters and the like.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a method for preparing a microbial preparation for decomposing plant stalks, and belongs to the fields of biotechnology and environmental protection engineering. Background technique [0002] my country produces hundreds of millions of tons of crop stalks every year, except for a small amount that is directly used as feed, and a large amount of remaining crop stalks are burned, polluting the environment. For many years, scientists have devoted themselves to using microorganisms to decompose crop straws and return them to the field. At present, straw decomposing agents are used more often. Regarding the preparation of straw decomposing agent, we retrieved the following public documents, for example: [0003] 1. Name: A microbial preparation for rotting crop stalks and its preparation method, authorized announcement number: CN1099393C, legal status: authorized, legal status announcement ...

AI Technical Summary

Problems solved by technology

[0005] We also retrieved other domestic methods of producing straw decomposing agents, most of which use wheat bran and rice bran as raw materials, and the production cost is relatively high; the produced decomposing agents have low bacterial activity and poor decomposing effect; some use Single strain, less enzyme production, no obvious decomposing effect
