Abstract: Abstract: In order to explore the introduction and cultivation adaptability of Panax notoginseng (Burk.)F.H.Chen in Xishuangbanna. Literature review and field surveys were used to compare the climate characteristics between Xishuangbanna and Wenshan, the main cultivation region of Panax notoginseng; Different elevations were designed for seeding experiment, different shade degree treatments and soil texture types were designed for cultivating experiment of Panax notoginseng. Then we observed its seeding and cultivating result, including seedling emerged time, seedling emerged rate, survival number, we also observed its plant height of different years old plant,and biological characteristics and phenology period of two years old plant. The result showed that Xishuangbanna and Wenshan had a similar climate characteristics; Seeding result among the three elevation(Jinghong 582m, Yiwu 895m, Menghai 1215m )showed that the elevation of 1215min above sea level Menghai had the highest seedling emergence rate (90.89%), and the seedling grown healthy. The three shade degree (60%, 70%, 80%) treatment showed Panax notoginseng had dark green leaves and relatively healthy growth under a 80% shade degree treatment; The three soil texture types (clay, sandy loam, clay loam) tests showed Panax notoginseng had a higher survival rate on the sand loam, there was still 57.31% plants left in the end of September. The seedlings were transplanted from Wenshan to Menghai of Xishuangbanna in December 2010, it got into seedling emergence stage in early March 2011, growing stage from late march to April, bud stage from June to July, flowering stage in August, fruiting stage from September to November, all of the results showed Panax notoginseng had a similar phenophase in the two district. The two years old plant had a reproductive capacity, the fruiting rate was 19.29%, the seeding rate was 49.78%. Finaly, we got a conclude, that some areas in Xishuangbanna had a introduction and cultivation adaptability for Panax notoginseng. Specific requirements included as fowolls: the optimum elevation was below 1200m, the shade degree was not less than 80%, the suitable soil type was sandy loam.
