| 摘 要： | 三七是云南独具特色的生物资源,它的根是著名、传统的重要中药材,云南文山是中国三七的道地产区,也是主要种植区。目前,三七种植在文山地区经济发展中占有重要地位。但三七生产上存在着严重的连作障碍问题,极大地限制了云南三七产业的发展。本文综述了三七连作障碍产生的机制和控制的方法,并从病原微生物和土传病害增加、土壤盐分累积和酸化、养分失衡和植物自毒效应等方面综合分析了三七连作障碍的成因,在此基础上探讨了三七连作障碍的防治途径。

| Abstract: | Panax notoginseng is a typical biological resources in Yunnan Province,and its roots is well-known in the traditional Chinese medicine（TCM）.Wenshan of Yunnan Province is the original and main cropping region of P.notoginseng in China.Now the cultivation of P.notoginseng has been one of key industries in Wenshan.However,it is severely inhibited by sequential cropping obstacles,which strongly influence on the development of P.notoginseng in Yunnan.The production mechanisms and control methods of sequential cropping obstacle of P.notoginseng is summarized systematically in this paper.Further,the causes including the increase in harmful microorganism and soil-transmitted diseases,the salt accumulation and soil acidification,the nutrient disequilibrium,the plant autotoxicity etc.are discussed.Based on the analysis,the control methods of sequential cropping obstacle were recommended. |
