根际微生物在番茄主要土传病害防控中的应用OA

Soil-borne diseases represent a major constraint to the sustainable development of the tomato industry.Traditional chemical control methods have drawbacks such as inducing pathogen resistance and causing environmental pollution.As core component of the soil ecosystem,rhizosphere microorganisms demonstrate significant advantages in the prevention and control of soil-borne diseases.This review summarizes the composition of tomato rhizosphere microbial communities and their relationship with host plants,elucidating the mechanisms and application effects of rhizosphere microbes in controlling major soil-borne diseases such as bacterial wilt and early blight.These effects are achieved through pathways including secretion of antimicrobial substances,competition for nutrients and ecological niches,induction of systemic resistance,and modulation of the soil microbial environment.In addition,the characteristics of different functional microorganisms and their microbial formulations are compared.However,current production applications of rhizosphere microorganisms still face challenges such as insufficient colonization stability of microbial agents,poor environmental adaptability,and lack of product standardization.Future research should focus on elucidating rhizosphere microorganism-plant-soil interaction mechanisms,combined with synthetic microbial community construction and formulation process optimization,to advance the application of rhizosphere microorganisms in the green control of tomato soil-borne diseases.
