摘要： 为解决烤烟新品种推广过程中的施肥问题，以‘云烟97’为试验材料，采用裂区试验，对该品种在不同施氮水平和氮钾肥配比下进行了研究。结果表明，施氮水平、氮钾配比对主要化学成分、化学协调性指标和化学质量综合得分的影响达极显著水平，施氮水平和氮钾配比的互作效应明显；从化学综合质量来看，随施氮量增加，烤烟化学综合质量先升高后下降，以施氮量180 kg/hm2的烟叶化学综合得分最高；随氮钾比下降，烤烟化学综合质量提高，以氮钾比1:3的烟叶化学综合质量最好；在所有处理组合中，以施氮量180 kg/hm2、氮钾比1:3烟叶化学综合质量最好，其次是施氮量180 kg/hm2、氮钾比1:2.5的处理。在株洲茶陵县，获得化学品质较好的烟叶，需施氮180 kg/hm2，保持氮钾施用比例1:(2.5~3)为宜。

Abstract: In order to solve the problem of new flue-cured tobacco varieties to promote the process of fertilization, taking ‘Yunyan 97’ as experimental material, Field trials were conducted to investigate the effects of nitrogen fertilizer and ratio of N to K on flue-cured tobacco chemical quality. The results indicated that, effects of nitrogen rate, ratio N to K, and their interaction on tobacco chemical compositions, chemical harmony indices and chemical harmony score were up to significant levels. With the nitrogen rate increased, tobacco chemical harmony score(CHS) increased first then decreased. With the ratio of N to K decreased, tobacco chemical harmony score (CHS) increased. In all these treatments, treatment of nitrogen rate 180 kg/hm2, and ratio of N to K reached 1:3 was of best comprehensive chemical quality, followed by the treatment of nitrogen 180 kg/hm2, ratio of N to K reached 1:2.5. In Chaling County, to obtain get tobacco with good chemical quality, to be N 180 kg/hm2 was recommended with a ratio of N to K of 1:(2.5-3).
