强还原土壤灭菌研究进展

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。

Advances in Method of Reductive Soil Disinfestation

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.
