Abstract

The invention discloses a composite bacterial preparation as well as a preparation method and application thereof, which belong to the technical field of agricultural biochemistry. The composite bacterial preparation comprises the following components in parts by volume: 10-40 parts of brevibacillus brives fermentation bacterial liquid, 10-40 parts of pseudomonas fluorescens fermentation bacterial liquid and 15-45 parts of sugarcane thermophilic actinomyces, wherein the bacterial count in each mol of fermentation liquid is 0.4-0.7 billion. The strains of brevibacillus brives, pseudomonas fluorescens and sugarcane thermophilic actinomyce are separated from rabbit dung and fungi residues; and fermentation bacterial liquids of the separated strains are mixed according to a proper proportion to form the composite bacterial preparation. The composite bacterial preparation disclosed by the invention can be used for accelerating the degradation of organic materials and reducing the conversion of organic nitrogen into gaseous nitrogen, so that the composite bacterial preparation can present stronger ammonia-suppressing and decomposing capabilities in the fermentation process of pig manurecompost; and a smaller amount of ammonia gas is released while thorough decomposition of pig manure is accelerated.

Description

technical field

[0001] The invention relates to a composite bacterial agent and its preparation method and application, in particular to a composite bacterial agent for treating pig manure, its preparation method and application, and belongs to the field of agricultural biotechnology. Background technique

[0002] With the continuous large-scale development of the breeding industry, a large amount of poultry manure produced seriously pollutes the environment and restricts economic development, which has become an important issue of ecological and environmental protection that cannot be ignored. In 2000, the output of livestock and poultry manure in my country reached 3.64 billion tons, which was 3.8 times the amount of industrial solid waste in the same period. According to statistics, the daily excretion of feces and urine of a pig is 6kg, which is 5 times that of human excrement and urine, and the annual output of feces and urine is about 2.5t. With the improvement of peo...
