The application discloses a
Streptomyces caniferus QS2-7 and application thereof, and belongs to the technical field of microorganisms. The application separates and obtains a
Streptomyces caniferus QS2-7 with a preservation number of CGMCC No.32328. Experiments show that the strain QS2-7 has a strong inhibiting effect on various
plant pathogenic bacteria, and has superior biocontrol potential. The strain has the functions of
nitrogen fixation,
phosphorus solubilization and
protease production, can effectively degrade autotoxic substances generated in the process of planting plants, and can relieve
autotoxicity. The strain can significantly promote the growth of
plant plants, effectively reduce the incidence of diseases, and has high application value in green control of
plant diseases and
continuous cropping production.
