The invention belongs to the technical field of microorganisms, and particularly relates to
pseudomonas monteilii BDLZ-3 and application thereof in relieving
continuous cropping obstacles of crops. The invention discloses a strain of
pseudomonas monteilii BDLZ-3, the preservation number of which is CGMCC (China General
Microbiological Culture Collection Center) No.34349. The
pseudomonas monteilii BDLZ-3 is separated and screened from the nature for the first time,
phenolic acid autotoxic substances generated in the
ginseng continuous cropping obstacle process can be efficiently degraded, the degradation rate of
benzoic acid can reach 95.36%, various phenolic acids such as
vanillic acid,
cinnamic acid,
palmitic acid and
gallic acid can be effectively degraded, and the degradation spectrum is wide; when the
pseudomonas monteilii BDLZ-3 is applied in a field, the content of
benzoic acid in soil can be effectively reduced, meanwhile, the occurrence of
ginseng root diseases can be controlled to a certain extent, the prevention and
treatment effect reaches 41.23%, the growth indexes such as
root length and root thickness are remarkably improved, and the yield increasing effect is achieved.
