The invention discloses a soybean
phospholipid disease-preventing and root-promoting
microbial agent as well as a preparation method and application thereof, and belongs to the technical field of microorganisms. The
microbial agent comprises a
microbial composition, modified enzymolysis soybean
phospholipid, a carrier and auxiliary components. According to the invention, the modified enzymolysis soybean
phospholipid and microorganisms are combined to achieve a synergistic effect. According to the method, soybean phospholipid is modified and subjected to enzymolysis, and the steps of pretreatment, stepped low-
temperature treatment, enzymolysis treatment,
enzyme inactivation and purification and the like are carried out, so that the quality and performance of the soybean phospholipid are improved, the
rhizosphere colonization rate of strains can be increased, the
disease prevention and root promotion effects can be improved, the soil micro-
ecological environment can be improved, and good growth conditions are created for
plant root systems; and the
disease-preventing and root-promoting effects of the
microbial agent are further enhanced. The microbial agent disclosed by the invention can be used for remarkably reducing the morbidity of wheat sharp eyespot and reducing the use amount of chemical pesticides, can also be applied to planting of other crops, and can play a role in preventing and controlling various
plant diseases and promoting
root growth.
