摘　　要：随着经济和技术的快速发展,以高投入高产出、高频种植等为特点的集约化种植已成为我国重要的农业生产模式。伴随集约化种植程度不断提高,作物土传病害频发,且易发生酸化、次生盐渍化、土壤板结等土地退化现象,往往造成作物连作障碍。强还原土壤灭菌方法(reductive soil disinfestation,RSD)作为一种环境友好型方法,兼具杀灭土传病原菌和改善土壤理化性质、易操作和处理时间短等特点,已成功用于作物连作障碍的防治。本文根据不同作物类型及不同土传病原菌,归纳总结了RSD处理过程所采取的有机物质类型、施用量、温度条件、淹水覆膜状况及灭菌效果。With the rapid development of economy and technology,intensive cultivation characterized by high input and high-frequency planting have become important patterns of agricultural production in China.With farming cultivation increasing steadily in intensiveness,such as soil-borne pathogens,soil acidification,secondary salinization,soil consolidation and so on occur more frequently,these problems often cause seriously successive cropping obstacle.Reductive soil disinfestation(RSD)is an environment-friendly method,which has the characteristics of inhibiting soil-borne pathogens and improving soil physicochemical properties,convenient and easy to operator,and short processing time.It has been successfully applied to the successive cropping obstacle.Based on different crop types and soil-borne pathogens,this article summarizes the types of organic matter,application rates,temperature conditions,flooding,lamination and disinfestation effects of the RSD method.
