摘　　要：利用大田随机区组试验研究了攀枝花地区3种增钾肥配方:烟草专用肥料、增施硫酸钾、增施氯化钾对烤烟烟叶产量、品质及土壤养分含量的影响。结果表明,与烟草专用肥料相比,增施硫酸钾使烟叶产量和产值分别增加2.2%和10.1%,中等烟叶比例提高10.0%;增施氯化钾使烟叶产量和产值分别增加3.4%和12.2%,上等烟叶比例增加5.8%。增施硫酸钾或氯化钾均增加了烟叶钾含量和钾/氯比值。增施硫酸钾降低了烟叶全氮含量,增加了施木克值;而增施氯化钾增加了烟叶全氮含量,降低了施木克值。本研究中土壤氯含量和烟叶氯含量均维持在较低水平。增施硫酸钾或氯化钾均增加了烟叶收获期烟田土壤碱解氮、有效磷及速效钾含量。因此,在攀枝花地区增施硫酸钾或氯化钾对提高烟叶产质量、培肥烟田土壤具有良好效果。A randomized block field experiment was arranged in Panzhihua to estimate the effects of three potassium fertilizer formula：special fertilizer for tobacco,increased potassium sulfate and increased potassium chloride on flue-cured tobacco （Nicotiana tabacum L.） leaf yield,quality and soil nutrient contents.The results indicated that,when compared with special fertilizer,application of increased potassium sulfate improved tobacco leaf yield and output value by 2.2％ and 10.1％,respectively,increased middle grade leaf proportion by 10.0％.Application of increased potassium chloride improved leaf yield and output value by 3.4％ and 12.2％,respectively,increased high grade leaf proportion by 5.8 ％.Application of both increased potassium sulfate and increased potassium chloride improved K contents and K/Cl in tobacco leaf.Application of increased potassium sulfate reduced total N content,increased,schmuek＇ s value in tobacco leaf.Application of increased potassium chloride increased total N content,decreased schmuck＇ s value.Cl contents both in soil and in tobacco leaf were quite low in this study.Application of both increased potassium sulfate and increased potassium chloride improved soil available N,P and K concentrations.Thus,application of both increased potassium sulfate and increased potassium chloride in Panzhihua had good effects on tobacco leaf yield and quality and soil fertility.
