连作对土壤质量和植株生长影响的研究现状

摘要

In order to research the reasons of soil quality deterioration and plant growth inhibited in greenhouse under continuous cropping .The continuous cropping effects of autotoxic substance ,soil physical and chemical characters ,biological characters and crop growth indices were introduced ,and the reasons which lead the soil quality decline ,restrain crop growth ,reduce crop yield and crop quality were analyzed and indicated that con-tinuous cropping was a burning question in sustainable development of facility production .%为探讨连作造成温室土壤质量衰退和植株生长受抑制的原因，综述了连作条件下自毒物质的累积，连作对土壤理化特性、生物学特性、植株生长指标的影响，分析了连作造成土壤质量退化的原因，造成作物生长受抑制，作物质量下降，品质降低，因此连作成为设施可持续发展亟待解决的问题。
