Keyword:  曲靖烟区植烟土壤养分;
Abstract: 为了了解曲靖烟区土壤养分状况,对采集的曲靖烟区3716个土样进行了养分状况分析,结果表明:土壤pH值平均为6.27,有机质含量3.7%,碱解氮、有效磷、速效钾含量分别为130.23、28.14、201.83 mg/kg,有效硼含量0.424 mg/kg,水溶性氯含量27.23 mg/kg.烟区有机质和碱解氮含量总体偏高;有效磷除富源县含量偏低外,其他县(市)都处于适宜或富余范围;陆良县速效钾含量偏低,建议补充钾肥;有效硼普遍缺乏.不同植烟县(市)间养分差异较大,各养分的变异程度大小顺序为水溶性氯>有效硼>速效钾>有效磷>有机质>碱解氮.因此,提出控氮、稳磷、保钾,合理增施硼肥的建议.
