| 摘 要： | 对永州南6县主产烟区的664个土壤样品养分进行了分析,结果表明：永州烟区土壤平均pH值为7.0,有机质38.7 g/kg,全氮2.4 g/kg,全磷0.8 g/kg,全钾11.1 g/kg,碱解氮215.2 mg/kg,有效磷21.2 mg/kg,有效钾84.2 mg/kg,有效铜2.9 mg/kg,有效铁72.7 mg/kg,有效锌1.8 mg/kg,有效硼0.1 mg/kg,有效锰19.3 mg/kg,有效钼0.1 mg/kg,有效硫35.9 mg/kg,有效氯29.4 mg/kg,代换性钙10.6（1/2 cmol/kg）,代换性镁0.9（1/2 cmol/kg）,阳离子交换量14.0 cmol/kg,针对永州烟区土壤偏碱,富含氮、氯、铁、硫、钙,缺钾、硼和钼的现状,提出了控氮、补钾、增硼和钼、减钙的整体施肥建议。
