Microorganism bacterium agent for straw and excrement mixed composting

Abstract

The invention discloses a microorganism bacterium agent for straw and excrement mixed composting. The microorganism bacterium agent is composed of the following strains: (2-6)*10<10>cfu of hair mould per gram, (2-6)*10<10>cfu of trichoderma virens per gram, (2-6)*10<10>cfu of geotrichum candidum per gram, (2-8)*10<9>cfu of saccharomyces cerevisiae per gram, (3-5)*10<11>cfu of bacillus thermophilus per gram, (2-6)*10<11>cfu of lactobacillus thermophilus per gram, (2-8)*10<10>cfu of white rot fungi per gram, (2-8)*10<10>cfu of monilinia fructicola per gram, (3-7)*10<8>cfu of pseudomonas putida per gram, (2-6)*10<11>cfu of nitrosococcus per gram, (1-4)*10<6>cfu of green algae per gram and (2-5)*10<7>cfu of blue-green algae per gram. The microorganism bacterium agent can promote a straw and excrement mixed aerobatic composting progress, shorten a composting period, improve a composting rotten degree, accelerate biodegradation of organic matters, alleviate ozone generation and diffusion during composting and reduce loss of nutrient substances such as nitrogen, can be applied to composting of different straw and excrement raw materials for composting enterprises and is used for producing bio-organic fertilizers.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste rapid composting inoculants, in particular to a microbial inoculant for mixed composting of straw and manure. Background technique [0002] At present, the annual output of straw in my country is about 700 million tons, and the discharge of manure from livestock and poultry breeding is about 1.73 billion tons. In addition, there are a large amount of activated sludge and municipal solid waste. Discarding a large amount of agricultural waste not only causes waste of resources, but also pollutes the environment. Today, the production of organic fertilizers through aerobic composting is a major way of disposing of agricultural waste. However, there are still many problems in the composting process. The composting cycle is long, the floor area is large, the odor pollution during the composting process is large, and the loss of nutrients such as nitrogen is large. Theory and practice have...

Problems solved by technology

There are big problems in this method: First, these single bacteria do have certain functions when cultured in the laboratory, but it is difficult to achieve the desired effect under the complex conditions of composting

This is because many single strains cannot grow and reproduce in the actual environment or are susceptible to the growth of other microorganisms; secondly, because there are many interactions between different microbial groups, the strains screened in the laboratory have certain functions. A single bacterium cannot fully prove that it has the same effect in a complex group; third, some microbial fermentation agents simply mix the fermentation strains together, and the antagonism between the strains is not thoroughly studied. This has just led to microbial strains in the fermentation process due to the antagonism between bacterial strains and can not achieve the desired effect; the fourth, can not effectively use the role of various enzymes produced by microorganisms

In the degradation process of organic matter, the degradation of enzymes is very critical, therefore, microbial agents that only contain microorganisms but do not contain enzymes cannot play a greater role

[0007] (3) The composition of the microbial agent is not rich enough and the pertinence is not strong

Although these microorganisms can be used in the composting process, they cannot solve some problems in the current composting process, such as the degradation and humification of hemicellulose and lignin, the suppression of odor, the maintenance of nitrogen, and insufficient oxygen.
