Fermentation microbial inoculum for rapidly promoting decomposition of pure sheep manure and application of fermentation microbial inoculum

The invention discloses a fermentation inoculant for rapidly promoting decomposition of pure sheep manure and application of the fermentation inoculant. Belongs to the technical field of microbial agents. The invention provides bacillus subtilis B-1 which is characterized in that the preservation number is CGMCC (China General Microbiological Culture Collection Center) No.22064, and a microbial agent, a bacterial fertilizer, a preparation method and a fermentation method of the bacillus subtilis B-1. According to the microbial agent for decomposing the pure sheep manure, provided by the invention, the activity of produced cellulase is 138.78 U/mL, and the activity of protease is 197.21 U/mL. Cellulose substances in sheep manure can be rapidly degraded in a high-temperature stage, small-molecular organic matters are generated, the content of organic matters and total nutrients in the fermentation process is promoted to be increased, meanwhile, the strain consumes oxygen and generates heat in the fermentation p
