Abstract

The invention relates to a compound microbial inoculum for decomposing straw as well as preparation method and application thereof. The compound microbial inoculum for decomposing straw comprises bacillus subtilis, bacillus megaterium, bacillus pumilus, bacillus cereus, fused lactobacillus, azotobocter chroococcum and saccharomyces cerevisiae. A straw bio-organic fertilizer can be prepared by processing the straw by adopting the microbial inoculum. The invention has easy material obtaining, simple production method; and in addition, the straw bio-organic fertilizer has sufficient organic matter fermentation and good fertilizer efficiency and can generate non-polluted green foods and organic foods and play certain roles in improving the soil quality and protecting the environment.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a composite microbial bacterial agent capable of decomposing straws and a bio-organic fertilizer containing the bacterial agent. Background technique [0002] my country is a large agricultural country, with abundant resources of various crops, such as straw, with an annual output of more than 700 million tons of straw. With the development of rural economy and the solution of rural energy problems, there are more and more residues of crop stalks, and the phenomenon of concentrated burning of crop stalks during the harvest season has become increasingly prominent, which not only pollutes the environment, endangers people's health, but also fills the air with smog. Affect traffic and flight safety, and easily cause fire. Therefore, the rational development and utilization of crop straw is particularly important. [0003] The extensive use of chemical fertilizers ...
