摘　　要：对毕节地区不同海拔高度主要等级烟叶464个样品的化学成分作常规项目检测分析。结果表明,毕节地区烟叶化学成分总体较为协调。烟叶中总糖含量中等偏高,两糖比80%的样品在0.8以上;烟碱含量适中,下、中、上部叶烟碱平均分别为1.49%、2.23%、3.08%,含量偏高的仅占10%左右;钾、氯含量大多数在适宜水平,糖碱比、钾氯比、氮碱比在适中水平。The chemical composition of 464 different grade tobacco leaves planted on different elevation in Bijie prefecture was determined. The results show that the proportion of main different chemical composition in tobacco leaves is balance totally; the total sugar content is slightly higher than the middle level, the ratio between reducing sugar and total sugar is up to 0.8 in 80%0 of the tested samples, the nicotine content is at the middle level, the average nicotine content of lower, middle and upper position leaves are 1. 49%, 2.23% and 3.08% respectively and the nicotine content of only 10% of the tested samples is higher than the normal level, the K and Cl contents of most tested sample are at the suitable level and the ratios of sugar to nicotine, K to Cl and N to nicotine are all at the middle level.
