摘要
连作障碍是农业生产中经常发生的一种病害,各种作物或轻或重都会发生,已成为世界性难题,给农业生产造成了严重损失。近年来,国内外学者从多方面、多角度对连作障碍进行分析。本文从土壤生物学环境的恶化、化感作用和土壤理化性状改变等角度阐述了连作障碍发生机制的研究进展。
The continuous cropping obstacle is a frequently occurring disease in agricultural production. A lot of crop cuhi- vation is facing the problem of continuous cropping obstacles. In recent years, many scholars had done a lot of research from many aspects. The research progress of deterioration of soil biological environment, allelopathic effects and the change of soil physicochemical characters were expatiated and summed up in this article.
