贵州六盘水地区马铃薯种植区域地球化学特征

应用环境地质、农业地质理论,对贵州省六盘水地区马铃薯种植区带开展地球化学调查研究,通过对调查区域的岩石、原生土、耕作土和马铃薯的采样、检测和统计分析,结果表明:岩石和原生土、原生土和耕作土、耕作土和马铃薯三者之间的各种元素含量丰缺具有相关关系,由此提出石炭系分布的新营、把士寨、粮蕨坝等区域适合马铃薯规模化种植;水城玉舍、水城大房子、盘县洒基、盘县上纸厂玄武岩分布区适合马铃薯规模化种植;二叠系碎屑岩分布区煤冲等地适合马铃薯规模化种植;盘县平关彭家屯侏罗系紫红色泥岩分布区也适合马铃薯规模化种植。水城小田坝、水城海坪和甘塘等二叠系茅口灰岩分布区域不适合马铃薯规模种植。

Regional Geochemical Characteristics of Agricultural Potato in Liuzhi, Panxian and Shuicheng Counties, Guizhou Province,P.R.China

Based on geo-environment and geo-agriculture theory, the regional geochemical characteristics of agricultural potato in Liuzhi, Panxian and Shuicheng counties, Guizhou Province were studied. Results show positive relative between elements of soil (rocks) and potato. On the basis of geo-environment of Liuzhi, Panxian and Shuicheng counties, authors suggest that distribution areas of the carboniferous strata (limestone) in Xinying, Bashizhai, Liangjueba, distribution areas of the Permian basalt in Yusai, Dafanzi, Shaji and Zhichang, and distribution areas of the Permian and Jourmian clastics in Meichon and Guangping are appropriate for potato agriculture, but distribution areas of the Permian limestone in Xiaotianba, Haiping, and Gantang are not.
