Bacillus laterosporus preparation

The invention belongs to the technical field of microbial preparation, and particularly discloses a bacillus laterosporus preparation. A preparation technology of the bacillus laterosporus preparation comprises the steps as follows: bacillus laterosporus strain selection in ampoule tubes; strain cultivation on test tube slant; strain cultivation in a shake flask; fermentation cultivation by a deep liquid in a seed tank; cultivation in a closed solid fermentation box; and obtaining of the bacillus laterosporus preparation. According to the invention, an advanced continuous fermentation technology of combination of deep liquid fermentation and closed solid fermentation is adopted, totally-closed self-control solid fermentation equipment is utilized, so that the whole process of solid fermentation is under totally-closed automatic monitoring, automatic detection, electronic display and automatic control are performed on environmental conditions such as medium components, formulas, temperatures, humidity, ventila
