根际微生态调控白菜根肿病发生的机制研究进展

白菜根肿病是由芸薹根肿菌(Plasmodiophora brassicae Woron)引起的一种常见土传病害，主要危害白菜的根部。根际是土壤-植物-微生物相互作用最活跃的关键微域，根际微生态系统中的微生物失衡是导致土传病害的重要因素，深入探究根际微生态与土传病害互作机制，有利于从根际微生物、抑病物质和功能代谢等方面挖掘防控土传病害安全高效的方法。本文综述了根际微生态与白菜根肿病的发生机制关系，从该病害的危害、发生的根际微生态机制及生防菌防治研究等方面综合分析了根际微生物调控白菜根肿病发生的机制，以期为白菜根肿病防控、促进土壤健康和维持根际微生态系统稳定提供理论依据。

Research progress in the mechanism of rhizosphere micro-ecology in regulating the occurrence of clubroot disease in Chinese cabbage

Chinese cabbage clubroot is a common soil-borne disease caused by Plasmodiophora brassicae Woron, which mainly damages the roots of Chinese cabbage. Rhizosphere is the most active key micro-domain of plant-soil-microbiome interaction, and the microbial imbalance in rhizosphere is a primary factor leading to soil-borne diseases. Deciphering the interaction mechanism between rhizosphere micro-ecology and soil-borne diseases is beneficial for finding safe and effective ways for the control of soil-borne diseases by rhizosphere microorganisms, disease-inhibiting substances, and functional metabolism. This paper introduced the relationship between rhizosphere micro-ecology and the occurrence of Chinese cabbage clubroot and expounded the mechanism of rhizosphere microorganisms in regulating the occurrence of clubroot disease in Chinese cabbage from the harm of the disease, rhizosphere microecology, and biocontrol strains. This review is expected to provide a theoretical basis for the control of clubroot disease in Chinese cabbage, improve soil health, and maintain the rhizosphere microecosystem stability.
