Objective: To study the relationship between the geo-authentic and geologic background system (GBS) and physicochemical properties of soil for the cultivation of Panax notoginseng. Method: The physicochemical properties of soil were analyzed, the geologic background system between producing areas of Yunnan and Guanxi of P. notoginseng was compared. Result: The distribution of P. notoginseng was restricted by GBS, The yellow-red soil of fragmentary rock mixed with carbonate seems to be most suitable for the growth. Conclusion: The most suitable soil for growing P. notoginseng is the neutral or weakly acidic soil with loam clay, particularly that with low base saturation percentage.
