Multifunctional fermentation composite microbial agent for rapid temperature rise and odor removal of livestock and poultry excrement compost, preparation method and application of microbial agent

Abstract

The invention discloses a multifunctional fermentation composite microbial agent for rapid temperature rise and odor removal of livestock and poultry excrement compost, a preparation method and an application of the microbial agent. The composite microbial agent comprises solid microbial agents of bacillus subtilis, bacillus mojavae, acinetobacter pittii, IIa, bacillus cereus and Nitrobacillus harbinensis BM62. The composite microbial agent is a multi-microorganism composite bacterial system with complementary functions, and has multiple effects of heat production in rapid fermentation, nitrogen preservation in biological deodorization, decomposition and degradation of compost materials and the like, so as to enable the livestock and poultry excrement compost to rapidly heat up, the unpleasant odor is obviously reduced, the nitrogen loss in compost is reduced, and organic substances such as cellulose and the like are rapidly and effectively decomposed, and thus the decomposition speedof compost materials is accelerated, the quality of compost products is improved, the agent cab be applied to the production of bio-organic fertilizers, the agriculture production cost is reduced, andmeanwhile, the environmental pollution caused by livestock and poultry excrement is solved, so that the agent has good application value and social significance.

Description

Technical field [0001] The invention belongs to the field of environmental application microorganisms, and in particular relates to a multifunctional fermentation composite microbial agent for rapid heating and deodorization of livestock manure compost, and a preparation method and application thereof. Background technique [0002] In recent years, my country’s animal husbandry has developed rapidly, and the resulting large amount of animal manure not only has not been effectively used, but has also caused serious environmental pollution. Although the use of livestock and poultry manure composting is an ideal way to use waste organic matter as a resource, there are still many problems, such as the volatilization of ammonia during the composting process, which causes air pollution and reduces fertilizer efficiency; the slow heating of the pile leads to organic macromolecules such as cellulose Insufficient degradation will extend the compost maturity time and so on. In response to...

Problems solved by technology

[0003] The common problem at present is the lack of basic theoretical guidance in the process of screening and cultivating complex microorganisms, which leads to the weak functionality of the screened strains; moreover, the lack of understanding of the fermentation process of compound culture and the interaction between various strains, As a result, the total number of live bacteria in the product is not high, so that the compost does not achieve the ideal effect of using compound bacterial agents to promote the process of decomposing
