Abstract

The invention discloses an insect-proof composite microbial inoculant and a preparation method thereof, and relate to the technical field of microbial inoculants. The microbial inoculant is prepared by mixing the following components in parts by mass: 100-150 parts of bacillus subtilis powder, 150-200 parts of trichoderma aureoviride powder, 50-90 parts of nitrifying bacteria powder, 80-120 partsof nitrogen-fixing bacteria powder, 120-180 parts of photosynthetic bacteria powder, 130-160 parts of protein decomposing bacteria powder and 110-170 parts of fiber decomposing bacteria powder. According to the composite microbial inoculant, the porous structure of diatomite can provide sufficient storage spaces for bacteria, wheat bran shell powder and wood chip powder can provide a suitable humidity environment for microbial bacteria and maintain the biological activity of the microbial bacteria during storage and transportation, when the microbial inoculant is scattered in a field, the microbial bacteria are hidden in a diatomite compound mixture and a bentonite compound mixture without being in direct contact with ultraviolet rays, so that the survival rate of the microbial bacteria isimproved.
