土壤微生物防控土传病害研究进展OA

With the advancement of agricultural intensification in China,soil-borne diseases have become increasingly severe,which pose significant challenges to sustainable agricultural production and ecological environment security.Thus,to achieve the goals of pesticide reduction and enhanced planting efficiency,the utilization of beneficial microorganisms for disease control and ecological regulation has emerged as a critical research direction now.Microbial biocontrol works by modulating the rhizosphere microbial environment,reducing pathogen inoculum density and virulence,and inducing systemic resistance in plants.These mechanisms alter plant-pathogen interactions and effectively suppress disease development.This article systematically reviews the current status of soil-borne diseases,elucidates the regulatory mechanisms of root exudates on microbial disease resistance,summarizes the biocontrol functions of beneficial soil microorganisms,outlines soil microbial control strategies,and analyzes the main challenges in current microbial regulation practices.This review aims to provide a reference for scientific research and practical applications in this field.
