The invention discloses a bio-control curing compound bactericide and a preparation method thereof. The bio-control curing compound bactericide is prepared by mixing 10 to 20 parts by weight of
Purpureocillium lilacinum, 10 to 20 parts by weight of
Pseudomonas fluorescens, 10 to 20 parts by weight of
Bacillus cereus, 10 to 20 parts by weight of
Bacillus mucilaginosus, 20 to 30 parts by weight of
Bacillus subtilis and 10 to 20 parts of
Trichoderma viride according to a certain ratio after being individually cultured. The bio-control curing compound bactericide provided by the invention has the advantages of preventing decline of a certain strain caused by culture after mixing, ensuring that the strains of the compound bactericide have different functions and perfectly matched, and having efficacies of fixing
nitrogen, solubilizing
phosphorus, dissolving
potassium, decomposing
organic matter, inhibiting pests, promoting
organic matter conversion, accelerating the
decomposition of
organic matter and nutrients, turning waste into treasure, reducing
pollution and the like. The product produce is a multi-functional compound bio-control bacterial group, has a good solution to the current soil improvement, agricultural
environmental protection, and waste
straw garbage, and is an ideal product capable of improving the soil, accelerating the growth of crops, and accelerating the
decomposition of organic matter.
