[Analysis on the geologic background and physicochemical properties of soil for the cultivation of Panax notoginseng in Yunnan province].
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.


METHODS
The physicochemical properties of soil were analyzed, the geologic background system between producing areas of Yunnan and Guanxi of P. notogiseng was compared.


RESULTS
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.


CONCLUSIONS
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.
