Abstract

The invention discloses a low-temperature fast fermentation agent for animal dung in cold regions as well as a preparation method and application thereof. The low-temperature fast fermentation agent comprises a component I and a component II, wherein the component I consists of the mixture of bacillus subtilis solid microbial inoculum, thermophilic cellulose-decomposing bacteria solid microbial inoculum and huge bacillus solid microbial inoculum, and the component II is micromonospora solid microbial inoculum. When the temperature in the cold regions is lower than 0 DEG C, the low-temperature fast fermentation agent for animal dung in cold regions is added in animal dung and straw compost materials, psychrophile can propagate fast by using starch, saccharides and other simple organics to generate biological heat to fast raise the temperature of the materials for high-temperature fermentation and deodorization. The low-temperature fast fermentation agent for animal dung in cold regions breaks through a low temperature limit, realizes high-temperature fast fermentation at the temperature below 0 and reduces ammonia volatilization in the process of composting.

Description

technical field [0001] The present invention relates to livestock and poultry excrement starter, in particular to low-temperature quick starter for livestock and poultry manure in cold regions and a preparation method thereof. The field of livestock and poultry manure low-temperature starter. Background technique [0002] There are many ways to process livestock and poultry manure, including physical methods, chemical methods, microbial fermentation methods, etc. The traditional old method of fermenting livestock and poultry manure as fertilizer is to let it accumulate and ferment naturally for 5-6 months, and it takes about 20 days or a month to make feed. The use of microbial fermentation to treat feces can not only speed up the fermentation process, shorten the fermentation time, reduce nitrogen loss, and increase the nutrient content of the fermented product; it can also dehydrate the fermented product by generating temperature through fermentation, saving energy, reduc...
