连作草莓根际土壤特征及修复技术研究进展

连作障害是制约草莓(Fragaria ananassa)发展的最大因素。笔者对国内外草莓连作障害的研究亮点进行了综述。土壤根际微生物区系变化，有益微生物减少，病原菌增加，有害化感物质积累是产生连作障害的主要原因。杀灭土壤病原菌，去除有害化感物质，把“病土”修复成“健康土”，是克服连作障害，实现草莓连茬种植的根本之路。对草莓连作障害机理的深入研究、土壤修复技术的应用研究仍然是未来发展的方向。

Review of Characteristics and Remediation Techniques of Rhizosphere Soil of Continuous Cropped Strawberry

Replant disease is a serious problem for strawberry cultivation. This article reviewed the present study of strawberry replant disease. The change of microflora of rhizospheric soil, the decrease of beneficial microorganisms, the increase of pathogens and the accumulation of allelopathic autotoxicity chemicals were thought as the main causes of replant disease. Killing of soil pathogens, degradation of autotoxicity chemicals were effective ways to remedy“disease soil”and achieve strawberry continuous cropping. Deep research on the strawberry replant disease mechanisms and application research of soil remediation technology still has a great potential value in future.
