摘要:

三七是中国名贵中药材之一,但其在种植环节中存在严重的连作障碍现象。连作障碍产生的原因主要有根际土壤微生物群落变化、土传病虫害增加、化感物质积累及其自毒作用、土壤理化性状恶变等。以前三七连作障碍研究多集中于单一因素对连作障碍的影响及三七病虫害防治,疏于综合分析各种因素间的内在联系和相互影响。本文总结了作物连作障碍形成机制的最新研究进展,综合分析了各因素间可能存在的关系,首次提出了各因素对三七连作障碍影响指数的评估方法,建议了未来研究方向,旨在为揭示三七连作障碍形成机制提供参考,并为连作障碍消减提供理论依据。
 

Abstract: Panax notoginseng is a rare traditional Chinese medicinal material, but its cultivation has been seriously affected by consecutive monoculture problems (CMP). The possible reasons for CMP include continuous croppingdriven changes in microbial community structure and soilborne diseases, in allelochemical accumulation and autotoxic effect, and in soil physical and chemical properties and so on. Previous efforts were focused on the effect of a single factor on CMP of P. notoginseng or on its direct prevention and remedy of pest and disease in replanted soil. However, few attentions were paid to the internal interconnections and interactions among the various factors inducing the CMP. In this review, recent progresses on the mechanism of CMP in P. notoginseng were presented. The possible relationships among various factors were discussed, and an evaluation method for effects of various factors on the index of CMP was proposed. The future study on the CMP of P. notoginseng was also suggested. This review would provide a better understanding of the CMP, and also a theoretical basis for mitigating the CMP of this herb.
