中文摘要:
      通过在贞丰县域开展全面1∶50000耕地质量地球化学调查工作,获得了区内耕地表层土壤元素含量或指标的高精度分析数据。为分析区内营养元素有效量和有效度的影响因素,选用了N、P、K、B、Mo、Zn元素及pH值、有机质含量、CEC数据进行分析。贞丰县表层土壤元素全量是其有效量的重要控制因素;pH值与K元素有效度呈正相关关系,与N、Mo、Zn元素有效度呈负相关关系;有机质与K、B元素有效度呈正相关关系,与Mo元素呈负相关关系;阳离子交换量与K、B元素有效度呈正相关关系,与P、Mo元素呈负相关关系。
英文摘要:
      By the 1∶50000 cultivated land quality geochemical survey in Zhenfeng county, the high-precision analysis data of the content or index of surface soil elements in the cultivated land were obtained. In order to analyze the factors affecting the effective amount and degree of elements in the region, N, P, K, B, Mo, Zn, pH value, organic matter content and CEC data were selected for analysis. The total surface soil element in Zhenfeng county is an important controlling factor of its effective amount. The pH value is positively correlated with K, and negatively correlated with N, Mo and Zn. The organic matter was positively correlated with K and B, and negatively correlated with Mo. The cation exchange volume was positively correlated with the efficiency of K and B elements, and negatively correlated with P and Mo elements.
