| 摘 要： | 应用经典统计学方法研究淮北平原砂姜黑土养分状况及其空间变异性。结果表明,土壤活性酸、有效P和有效B、Mn、Fe等微量元素含量的空间变异性较大,pH值及有效Ca、Mg、Zn含量的空间变异性很小,有机质及有效N、K、S、Cu等营养元素含量的空间变异性介于两者之间。土壤有效N、K、P、Zn、Mn较为缺乏,Ca、Mg、Cu和B等中微量元素含量丰富。养分缺乏程度为N>Zn>K>P>Mn,缺Fe、缺S土壤较少。

| Abstract: | In the light of the principle of classical statistics,the study on the status and spatial variability of nutrient of lime concretion black soil in Huaibei plain was conducted.The results showed that the spatial variability of active acid,available phosphorus,available trace element as boron,manganese and iron was larse;pH value and available calcium,magnesium and zinc was little and organic matter,available nitrogen,potassium,sulfur and copper was medium.Available N,Zn,K,P and Mn in soils were insufficient;medium and trace element as available Ca,Mg,Cu and B were abundant and few soil samples showed the deficient of Fe and S. |
