Analysis on the geologic background and physicochemical properties of soil for the cultivation of Panax notoginseng in Yunnan province / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the relationship between the geo-authentic and geologic background system (GBS) and physicochemical properties of soil for the cultivation of Panax notoginseng.</p><p><b>METHOD</b>The physicochemical properties of soil were analyzed, the geologic background system between producing areas of Yunnan and Guanxi of P. notogiseng was compared.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>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.</p>
