Abstract

The invention discloses a root-knot nematode killing composite microbial inoculum and a preparation method thereof, the root-knot nematode killing composite microbial inoculums comprises the following raw materials by weight: 50-70 parts of bacillus amyloliquefaciens and 50-70 parts of paecilomyces lilacinus, and the preparation method is as follows: preparation of a single microbial inoculum of the bacillus amyloliquefaciens on the basis of the bacillus amyloliquefaciens prepared in advance; preparation of paecilomyces lilacinus spores powder on the basis of the paecilomyces lilacinus prepared in advance; mixing of the microbial inoculums and the spores powder to obtain the root-knot nematode killing composite microbial inoculums. The beneficial effects are that: the root-knot nematode killing composite microbial inoculum has the advantages of no pollution, no residue, strong ability to kill nematodes and fast breeding, active strains containing in the microbial inoculums can produce indole acetic acid, rhzomorph and other substances, and has growth promotion and disease resistance function.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial agents, in particular to a compound bacterial agent for killing root-knot nematodes and a preparation method thereof. Background technique [0002] Root-knot nematode is a relatively common pathogenic organism, which mainly exists in the roots of soybeans, tomatoes and other crops. In land infected with root-knot nematode, plants generally grow slowly and are prone to diseases, so how to kill and control root-knot nematodes Nematode has become a major issue to be solved in agricultural development. [0003] At present, there are two main measures to kill root-knot nematodes: one is to treat the soil with chemical agents; the other is to carry out biological treatment, that is, to find the natural enemies of nematodes, expand the cultivation, and put them into the soil to carry out a virtuous biological cycle. Among them, although the treatment of soil by chemical agents can play a rol...
