在湖南浏阳烟稻轮作区开展了施氮量与氮磷钾配比对浏阳烟区烤烟农艺性状与产量的影响研究，结果表明：在施氮120~180 kg/hm2范围内，随施氮量增大，烤烟生育期延长、农艺性状改善、产量显著提高；同一施氮量条件下，烤烟产量因施钾量增大而提高，但处理间差异显著性与施氮量有关，在施氮150 kg/hm2以上时处理间差异显著。

Effects of nitrogen fertilizer rate and ratio of N, P and K on yield and agronomic traits of flue-cured tobacco were studied in Liuyang tobacco-rice rotation cropping area of Hunan Province. The results showed that when nitrogen fertilizer rate was within 120~180 kg/hm2, with increasing nitrogen fertilizer rate, the whole growth duration was prolonged, the agronomic traits were improved, and the yield was significantly increased; under the same nitrogen rate, yield of flue-cured tobacco was increased with the increasing potassium fertilizer rate, while the significance of difference among treatments related to the nitrogen fertilizer rate, and the difference showed significant when nitrogen fertilizer rate was higher than 150 kg/hm2.
