研究云南省陇川县脐橙园土壤与叶片养分状况，为脐橙园科学施肥提供理论依据。在脐橙园采集土壤（0～20和20～40 cm土层）和叶片样品，测定土壤和叶片养分含量，明确其丰缺状况，并计算土壤肥力综合指数。结果表明：在0～20 cm土层，土壤pH平均为5.43，31.7%的果园土壤pH在5.5～6.5，80%以上的脐橙园土壤有机质、有效磷、速效钾和微量元素含量（有效铜除外）处于适宜及以上水平，超过60%的土壤交换性钙、镁和有效铜含量处于缺乏水平；在20～40 cm土层，土壤pH变幅在4.22～7.49，91.4%的土壤有机质含量>15 g·kg-1，交换性钙、镁和有效铜含量低，其他养分处于适宜及以上水平。0～20 cm土层土壤pH、速效钾、交换性镁和微量元素（有效铁除外）含量显著高于20～40 cm，其他指标在两个土层间无显著差异。叶片磷、钾、钙和微量元素含量处于适宜及以上水平，49.3%的叶片氮含量和87.3%的镁含量处于较低水平。0～20和20～40 cm土层土壤综合肥力指数分别为0.57和0.46，均为中等水平。综上，陇川县脐橙园土壤pH较低，土壤交换性钙、镁及有效铜含量缺乏，其他养分适宜，叶片氮和镁含量严重不足，其他营养元素含量为适量及以上水平。因此，在生产中应适当施用石灰或碱性肥料调节土壤pH，土施或叶片喷施钙肥、镁肥和铜肥，提高脐橙园土壤和叶片营养水平，促进脐橙的提质增效。
