摘要： 利用在奉节脐橙种植区野外采集的表层土壤样的分析结果,探讨了土壤中常量元素、主要微量元素及土壤元素有效态的地球化学特征,结果表明:表层土壤中主要营养元素N、P、Corg三种元素含量较高,K元素含量一般;微量元素中Fe、Zn、B在该区表层土壤中的分布都较均匀,Mn、Mo在土壤中的分布不太均匀,Cu元素在表层土中分布不均匀;土壤元素有效态中有效P、有效态Mn、有效态Cu、有效S、i速效K、有效态Fe含量丰富。

Abstract: "In this paper,Fengjie navel orange growing areas in the surface soil samples collected in the field results of the analysis of major elements in soil,trace elements and major elements of an effective state of the soil geochemistry results show that:the main nutrient elements in soil N,P,Corg higher levels of three elements,K elements in general;trace elements,Fe,Zn,B in surface soil in the area are more evenly distributed,Mn,Mo in the soil is not evenly distributed,Cu elements in the surface uneven distribution of the soil;soil element in the effective state of the effective P,effective state Mn,effective state Cu,the effective Si,available K,the effective state of Fe is abundant.
