对湖北利川不同海拔高度和不同品种烤烟的研究表明，烟叶总氮和烟碱随海拔高度增加而降低，烟叶还原糖和钾含量随海拔高度的提高而增加。CF80的香吃味随海拔高度升高而降低，CT90和K326的香吃味随海拔高度增加而改善。K326的烟碱含量显著高于CF80和CT90，还原糖含量显著低于CF80和CT90，评吸总分在低海拔时最差，高海拔时居中。地膜覆盖和良好的抹杈管理将提高烟叶香气品质。利川适宜的留叶数为20片左右。造成1997年K326在利川表现一般的主要原因是留叶数偏少。

Study on the flue-cured tobacco of different varieties at varied altitude in Lichuan of Hubei Province showed that with the rise in altitude the nitrogen and nicotine contents of leaf decreased, but the contents of reducing sugar and potassium increased, the smoking quality of variety CF80 decreased, while those of CT90 and K326 increased. The nicotine content of K326 was remarkably higher than that of CF80 and CT90, whereas its reducing sugar content was significantly lower than that of CF80 and CT90.The smoking quality of K326 was the poorest at altitudes lower than 1100m,but was the second at altitudes higher than 1100m. CF80 was the best in smoking quality, but the poorest at altitudes higher than 1100m. Film mulching and good management in sucker control improved the smoking quality significantly. The suitable leaf number for Lichuan tobacco cultivation was around 20 pieces, within which it was most possible to obtain best smoking quality leaf. The main reason for the poor quality of K326 was too less leaves preserved.
