【摘要】：三七是我国特有的中药材,主产于云南大部和广西部分地区,而连作障碍是制约三七产量和品质提升的重要瓶颈。三七根际微生物及根内共生微生物的动态变化是三七连作障碍的重要诱因,也是目前的研究热点。对三七连作过程中根际土壤微生物、根内共生微生物的动态变化研究进展进行综述,特别是连作障碍中致病微生物的研究进展进行综合分析,并总结了相关生态学的研究现状;提出了2种研究三七连作障碍土壤微生物的方法:(1)可培养与免培养方法相结合对三七连作障碍过程中微生物动态变化进行研究;(2)针对重要致病微生物种进行实时定量跟踪。旨在为尽快削减三七连作障碍提供理论依据。
[Abstract]:Panax notoginseng is a unique Chinese medicine in China, mainly produced in most of Yunnan and parts of Guangxi, and continuous cropping obstacle is an important bottleneck restricting the increase of yield and quality of Panax notoginseng. The dynamic changes of rhizosphere microbes and symbiotic microorganisms of Panax notoginseng are the important inducement of continuous cropping obstacle of Panax notoginseng, and are also the research hotspot at present. This paper reviews the dynamic changes of rhizosphere microbes and symbiotic microorganisms in rhizosphere of Panax notoginseng (Panax notoginseng) during continuous cropping, especially the research progress of pathogenic microorganisms in continuous cropping disorders, and summarizes the research status of related ecology. In this paper, two methods of studying soil microorganism in continuous cropping of Panax notoginseng (P.notoginseng) were put forward. The microorganism dynamic changes during the process of continuous cropping of Panax notoginseng were studied by combining culture method and non-culture method). The real-time quantitative tracking of important pathogenic microorganism species was carried out. The aim is to provide theoretical basis for reducing the obstacle of Sanqi continuous cropping as soon as possible.
