Wood fiber degradation complex microbial inoculant of mixture of livestock and poultry manure and straw and application thereof

Abstract

The invention discloses a wood fiber degradation complex microbial inoculant of mixture of livestock and poultry manure and straw. The complex microbial inoculant is prepared from rhizomucor miehei NJAU-F4-5 fermentation liquor with the concentration of 109 / ml and the preservation number of CGMCC No.18135 and brevibacillus reuteri NJAU-N2 with the concentration of 109 CFU / ml and the preservation number of CGMCC No.18020. The wood fiber degradation complex microbial inoculant has the following beneficial effects: the production efficiency of organic fertilizer is improved, the economic benefitsand the ecological environment benefits of enterprises are improved, meanwhile, the straw degradation rate of the complex microbial inoculant reaches 20.55%, the straw degradation effect of the complex microbial inoculant is better than that of single bacteria and bacteria-free bacteria, the degradation time can be shortened, the degradation process is accelerated, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural microorganisms, in particular to a lignofiber-degrading composite microbial agent for a mixture of livestock and poultry manure and straw and its application. Background technique [0002] China is a big agricultural country in the world, and it is also a country with a lot of straw resources. Every year, more than 900 million tons of straw will be produced after harvesting crops. In recent years, the state has successively promulgated laws and regulations prohibiting straw burning; straw biogasification technology is not yet mature enough to be popularized in rural areas; open-air stacking cannot efficiently degrade straw due to the lack of functional microorganisms. A notable feature in the development of my country's large-scale agriculture (crop production, aquatic products, animal husbandry) is that the proportion of my country's animal husbandry output value is increasing. For example, ...

AI Technical Summary

Problems solved by technology

However, the composition of livestock and poultry manure and straw is complex, including protein, fat, organic acid, cellulose, hemicellulose, and inorganic salts. At present, relying on a single bacterial species or a simple combination of complex bacterial flora is insufficient and slow.
