| Abstract: | As an important medicinal plant resource in Yunnan province, Panax notoginseng plays an important role in the field of medicine in China. Due to the serious continuous cropping obstacles in its production process, it restricts the development of planting industry, Chinese herbal slices industry, pharmaceutical industry and other related industries. In this paper, the species of root exudates of P. notoginseng and their effects on soil microbial community structure, soil physical and chemical properties, soil enzymes activities and plant growth of P. notoginseng were summarized. And the ecological effects of root exudates of P. notoginseng on continuous cropping obstacles were discussed, as well as the measures relieving and preventing continuous cropping obstacles of P. notoginseng. |
