摘　　要：土传病害是农业生产中的重要植保难题,对作物的健康生长构成严重威胁。该类病害的发生机制复杂,尤其与土壤微生态密切相关,其中土壤微生态失衡是其主要诱因之一。土壤调理剂通过优化土壤生物、物理及化学特性,改善土壤环境,提升作物抗病能力,从而缓解土传病害的发生并减轻连作障碍。通过系统分析土壤生态因子与土传病害之间的关系,归纳不同类型土壤调理剂的特征,并从土壤微生态调控角度探讨其作用机制。同时,综述了土壤调理剂在土传病害防治中的应用现状及发展趋势,以为土壤健康管理与病害综合防控提供科学依据和技术支撑。Soil-borne diseases are a major challenge of plant protection in agricultural production,posing a significant threat to crop health.The occurrence mechanisms of these diseases is complex and closely related to soil microecology,with soil microecological imbalance being one of the primary causes.Soil conditioners can optimize soil biological,physical,and chemical properties,improve soil conditions,and enhance crop disease resistance,thereby mitigating the occurrence of soil-borne diseases and alleviating continuous cropping obstacles.This study systematically analyzes the relationship between soil ecological factors and soil-borne diseases,summarizes the characteristics of different types of soil conditioners,and explores their mechanisms from the perspective of soil microecological regulation.Additionally,the application status and development trends of soil conditioners in soil-borne disease prevention and control are reviewed,providing scientific basis and technical support for soil health management and comprehensive disease prevention.
