为了指导江西红壤旱地烤烟合理施用磷钾肥，以烤烟品种K326为试验材料，在红壤旱地上试验研究磷钾肥配施对烟叶产量和品质的影响.结果表明，红壤旱地上缺施磷钾肥的烤烟长势较差，烤烟经济效益偏低，磷钾肥配施的烤烟，烟叶长势好，高量磷钾配施能提升烤烟品质与经济效益.在氮肥用量142.5 kg/hm2的情况下，随着磷钾肥配施比例的增加，烤烟烟碱与总氮含量呈现降低的趋势，但烤烟糖碱比、总糖与还原糖呈现增加的趋势.烤烟含硼量与总糖、还原糖呈显著负相关，与烟碱、总氮呈显著至极显著正相关，烤烟中含铁量与烟碱呈极显著负相关.在江西红壤旱地烟区，施用氮142.5 kg/hm2的基础上，高量磷钾肥配施( N︰P2 O5︰K2 O ＝1︰1.2︰3.0)将更有利于烤烟烟碱含量的平衡与产量和品质的提高.

In order to explore the rational application of potassium and phosphorous fertilizers in tobacco cultivations in the red soil of Jiangxi province, a field trial was conducted to study the effects of potassium and phosphorous fertilizers mixed applica-tion on yield, quality and nutrient distribution of flue-cured tobacco planted in red soil using the tobacco variety “K326” as the tested materials. The results showed that tobacco plant growing was poor and economic benefit of flue-cured tobacco was low without the application of potassium and phosphorous fertilizers, but tobacco plant growing was well in case of potassium and phosphorous fertilizers mixed application. High levels of phosphorus and potassium fertilizers mixed application could improve the quality and economic efficiency of flue-cured tobacco. The total sugar, reducing sugar and the rate of sugar to nicotine was increased and nicotine and total N was decreased with the increasing of phosphorus and potassium fertilizers mixed application. Born content of tobacco was positively correlated to the content of nicotine or total N, but negatively correlated to the content of total sugar or reducing sugar, and tobacco iron content was significantly negative correlated to nicotine. So it is suggested that the application of N 142. 5 kg/hm2 with N∶P2 O5∶K2 O =1∶1. 2∶3. 0 was recommended for the balance of nicotine and improving the quality of flue-cured tobacco in the tobacco-growing areas of red soil in Jiangxi province.
