Composite microbial preparation containing bacillus subtilis

The invention belongs to the technical field of microbial preparations, and particularly relates to a composite microbial preparation containing bacillus subtilis. The composite microbial preparationcontaining the bacillus subtilis comprises the following components in parts by weight: 40-60 parts of composite microbial powder, 20-30 parts of a composite carrier and 2-10 parts of a protective agent. According to the composite microbial preparation containing the bacillus subtilis, through the mutual coordination effect of bacillus subtilis, bacillus cereus and inulin bacillus, the side effects caused by antibiotic abuse are overcome, and a safe and green composite microbial preparation is provided for human beings; and meanwhile, the number of spores generated in the biological bacteriumfermentation process is effectively increased, and an important guarantee is provided for effectively prolonging the service life of the microbial agent and maintaining the pesticide effect and stability of the microbial agent
