摘　　要：根肿病严重危害油菜、白菜、甘蓝、芥菜在内的十字花科作物,因此研究一种有效的防治方法以降低该病害的发生是非常重要的。十字花科作物根肿病的病原菌—根肿菌能以休眠孢子的形式长期存在于土壤中,一旦环境条件适宜即可萌发并迅速传播。生防菌是从拮抗病原菌和诱导植物抗性的角度寻求防治病害的一种方法。作者首先对获得十字花科作物根肿病生防菌的方法进行阐述,重点总结了生防菌的来源和筛选的方法。为了更好地利用生防菌,又简要综述了生防菌菌株的分类鉴定、发酵及拮抗物质等方面的研究进展,分析了施用生防菌的方式和时间。并指出了目前存在的问题及开发应用的前景。Clubroot is becoming a serious threat to cruciferous crops,including Brassica napus ,B .pekinensis ,B . oleracea ,B .juncea .It is very important to develop an effective control method to reduce the occurrence of this disease.Plasmodiophora brassicae ,which causes clubroot disease in cruciferous crops,can form resting spores sur-viving for long periods in the soil.If the environmental conditions are suitable for the germination of P .brassicae resting spores,this disease spreads quickly.Biocontrol microorganisms suppress clubroot of cruciferous crops via antibiosis and induced host resistance.The present review focuses on research progresses in the methods of acqui-ring biocontrol microorganisms.We emphatically summarize the sources and screening methods of biocontrol mi-croorganisms.In order to make better use of biocontrol microorganisms,advances in classification,fermentation and antagonistic substances of biocontrol microorganisms and an analysis of the methods and time for applying bio-control microorganisms are reviewed.The problems to be solved and prospects for development and application were also discussed.
