采用田间试验，以烤烟品种云烟87为材料，研究不同钾肥对烤烟主要化学成分的影响。结果表明，柠檬酸钾处理鲜烟中总氮、粗蛋白含量在各时期最为适宜，烟株的氮代谢最为协调，并提高了鲜烟中还原糖、有机钾含量。烤后烟叶化学成分及其比值中，硝酸钾处理粗蛋白含量最高；硫酸钾处理钾含量最高，但有机钾含量最少，氯离子、硫酸根含量最高；柠檬酸钾处理氯离子、粗蛋白含量最少，有机钾、还原糖、总糖含量最多，K2 O／Cl 最高，烟叶的品质最好。总体来看，鲜烟和烤后烟叶在3个处理中均以柠檬酸钾的效果最好。

With the tobacco (Nicotiana tabacum L.) cultivar Yunyan 87 as material, the effects of dif-ferent varieties of potash fertilizer on the main chemical components of flue -cured tobacco were studied by field experiments .The results showed that under the potassium citrate treatment the total nitrogen and protein content had the most suitable value in each period of fresh tobacco , and the nitrogen metabolism was the most coordinating in tobacco plants;the content of reducing sugar and organic potassium of fresh tobacco were also improved .Among the chemical compositions and their ratio in flue -cured leaves , the protein content was the highest under the KNO 3 treatment .The potassium content , chloride ion and sulfate content were the highest under the K2 SO4 treatment, but the organic potassium content was the lowest .Under the potassium citrate treat-ment, the chloride ion and protein content was the lowest , while the content of organic potassium , reducing sug-ar and total sugar , and the ratio of K 2 O/Cl were the highest , so the quality of tobacco was the best .Overall , the quality of fresh leaves and flue -cured tobacco were both the best under the potassium citrate treatment .
