摘要
针对三七生产中连作障碍现象,综述其产生的原因,主要从土壤质量下降、土壤微观生态系统发生变化、自毒作用、土传病害和线虫等方面来探讨,从而提出连作障碍的防治途径,为解决三七连作障碍提供帮助。
Aiming at the obstacles caused by continuous notoginseng cropping, the paper summarizes the reasons and puts forward preventing measures through discussing five aspects： soil quality degradation, soil microcosmic ecosystem change , auto toxicity, disease from soil and eelworm, which can give a hand to solving the obstacles.
