广西莪术道地产区地质背景及土壤理化状况分析

Analysis on the Geologic Background and Physicochemical Properties of Curcuma Kwangsiensis Genuine Producing Area in Guangxi

目的:研究广西莪术道地性与其地质背景系统(GBS)、土壤理化状况的关系。方法:比较广西莪术产区的地质背景系统,分析土壤理化状况。结果:广西莪术道地产区的分布受GBS的制约,广西莪术最适宜的地质背景为沙岩和页岩混合型黄红壤区。结论:广西莪术道地产区土壤受其成土母质影响;道地广西莪术最适合的土壤类型是偏酸性的壤质土或砂壤土,对低盐基饱和度的土壤较适应,可作为其道地性的特征之一。

objective： The aim is to study the influence of physicochemical properties and geologic background system （GBS） on the geo-herbalism property of Curcuma Kwangsiensis. Methods ： The physicochemical properties and GBS of Curcuma Kwangsiensis from t genuine producing area in Guangxi were analyzed. Results ： The genuine producing area of Curcuma Kwangsiensis was showed to be influenced by GBS, and the most suitable GBS was red soil mixed with shale. Conclusion： The soil of Curcuma Kwangsiensis genuine producing area is influenced by its parent material. The most suitable soil for Curcuma Kwangsiensis is the acidic soil with loam or sandy loam, particularly with low base saturation percentage, which may be one geo-herbalism character of Curcuma Kwangsiensis.
