通过多条基岩-土壤剖面和区域性土壤地球化学样品的微量元素丰度测试,分析了宁国地区不同基岩类型地球化 学元素在岩石和土壤中分布的基本特点,表明同一地层的岩-土系统在不同地点有基本相同的元素迁移规律,导致土壤中 的微量元素分布特征受控于其下地质单位的空间分布,植物生长必需的微量营养元素Fe、Mn、Cu、Mo、Zn、B6种元素表现 出在南华纪-寒武纪地层中向土壤强烈富集的趋势.岩-土系统元素迁移特点对宁国市天目山区重要名优特产品-山核 桃的生长环境产生重要影响,该区主导性名特优产品———山核桃,应该选择南沱组、兰田组、杨柳岗组、华严寺组、西阳山组 等地层出露的地段种植才能产生好的经济效益.
Based on the trace element abundance tests of multiple bedrock-soil profiles and regional soil-geochemical samples, the basic characteristics of the distribution of geochemical elements with different bedrock types in the rock and soil in Ningguo area are analyzed. It is shown that the same strata of rock-soil The system has the same rules of element migration in different locations, resulting in the distribution of trace elements in soil being controlled by the spatial distribution of the underlying geological units and the trace elements Fe, Mn, Cu, Mo, Zn and B which are necessary for plant growth Element shows a strong tendency to enrich the soil in the Nanhua-Cambrian strata, and the elemental migration of rock-soil system has an important influence on the growth environment of the peculiar peculiar peculiar specialty product in Tianmu Mountain, Ningguo City. Famous special products - pecan, Nantuo, Lantian, Yangliugang, Huayansi, Xiyangshan Formation and other strata should be planted to produce good economic benefits.
