The method relates to a low cost method utilizing critic acid wastewater to produce a bacillus amyloliquefaciens bio-control inoculant capable of preventing and treating plant diseases and promoting plant growth, and belongs to the technical field of microbiological pesticides and microbiological fertilizers. Plant ash rich in potassium carbonate obtained from a biomass thermal power plant is taken as an additive for a critic acid wastewater pretreatment, the critic acid wastewater is subjected to an aerobic culture treatment to massively obtain bacillus amyloliquefaciens fermentation broth, and finally biological carbon is taken as the carrier to prepare the inoculant capable of preventing and treating plant diseases and promoting plant growth. The technology has the advantages of low cost and simple preparation, at the same time critic acid wastewater is recycled as a valuable resource, and the pollution discharge is reduced. The inoculant can be applied to the vegetable production, the ...
