摘　　要：在奉节脐橙种植区野外采集表层土壤样进行分析,探讨了土壤中常量元素、主要微量元素及其有效态的地球化学特征。表层土壤中,主要营养指标N、P、Corg含量较高,K含量一般;微量元素Fe、Zn、B分布较均匀,Mn、Mo分布不太均匀,Cu分布不均匀;土壤元素有效态中,有效态P、Mn、Cu、Si、K、Fe含量丰富。Surface soil in the growing area of Fengjie navel orange was collected for analysis,and geochemical characteristics of major elements and main trace elements as well as their effective state were investigated.The content of main nutrient indices N,P and Corg is relatively high,while K content is ordinary.In trace elements,Fe,Zn and B are of relatively even distribution,Mn and Mo are somewhat unevenly distributed,and Cu is very unevenly distributed.As for soil element effective state,effective P,Mn,Cu,Si,K and Fe are abundant.
