Abstract S572; [目的]明确保山市植烟区土壤肥力水平,以提高施肥针对性,为保山市植烟区土壤培肥和烟草种植提供理论依据.[方法]采用模糊数学模型隶属函数法对1465份植烟区土壤样本进行研究,探索土壤养分的时空变异特征,并应用肥力适宜性指数对土壤肥力适宜性进行综合评价.[结果]2015-2019年,保山市5县(市、区)植烟区土壤pH降低,有效硼含量无明显变化,有机质、碱解氮、有效磷、速效钾、有效镁、有效锌、水解性氯含量增加;土壤pH、有效硼含量和水溶性氯含量较适宜,有机质、碱解氮和速效钾含量丰富,有效磷、有效镁和有效锌含量较高;植烟区土壤肥力适宜性指数平均值为0.589,土壤肥力状况良好,各县(市、区)土壤肥力适宜性指数表现为昌宁县＞施甸县＞龙陵县＞隆阳区＞腾冲市.[结论]保山市烟区土壤较适宜烟草生长.针对5县(市、区)植烟土壤养分状况与土壤肥力特征,建议合理控制磷肥、镁肥和锌肥的施用量,提高肥料的利用率.
