摘要
连作障碍严重威胁西洋参产业可持续发展。连作障碍可能与自毒/化感作用、根际微生态系统失衡、病害、虫害等因素有关,其中根际土壤微生态系统失衡是关键因素之一。在西洋参栽培过程中根际土壤微生态逐渐失衡引发化感物质积累、土壤理化性质恶化、土传病害严重等一系列问题,老参地尤为突出。本文综述了西洋参栽培过程中微生态系统平衡的重要性及微生态系统失衡所面临的主要问题,并试图从平衡微生态系统方面提出西洋参连作障碍消减策略。
Continuous cropping obstacle seriously threatens the sustainable development of American ginseng industry.It may be related to autotoxicity/allelopathy,imbalance of rhizosphere microecosystem,diseases,insect pests,etc.Among them,the imbalance of rhizosphere soil microecosystem is one of the key factors.During the cultivation of American ginseng,the gradual imbalance of rhizosphere soil microecology has caused a series of problems such as accumulation of allelochemicals,deterioration of soil physical and chemical properties and serious soil-borne diseases,especially in the old ginseng cultivation fields.In this article,the importance of microecological balance during the cultivation of American ginseng and the major problems facing microecological imbalance were summarized in order to find strategies to reduce the continuous cropping obstacles of American ginseng from balancing the microecosystem.
