Abstract：In order to explore suitable drainage body for the planting of Panax notoginseng, three drainage treatments, eucalyptus bark SP, corn stalk YM, tobacco stem YG, were designed through field experiments. Three kinds of drainage treatments were designed: eucalyptus bark(SP), corn straw(YM)and tobacco stalk(YG). The growth, soil microbial quantity and nutrient content of Panax notoginseng in each growth period were studied when the depth of drainage was 20 cm. The results showed that compared with the treatment of CK, the growth index, soil available nutrient content and the number of microorganisms in soil under different drainage treatments were significantly increased. The drainage treatments had the effects on increasing the nutrients of soil and reduced the losses of nutrients in soil. In the 0-40 cm soil layer, after irrigation 1 day and 7 days, the moisture content of soil was expressed as CK>YG>SP>YM. Compared with the CK, the incidence rate of Panax notoginseng treated by YM was significantly reduced by 34.67%. Through comprehensive comparison, the best scheme under this experimental condition is to use corn straw as the drainage water for the field of Panax notoginseng.
