摘　　要：本文对1996—2006年间豫西地区的气候和烤烟化学成分特点以及两者关系分析表明：光、温、水、热条件适宜烤烟生长，部分烟叶含糖量和烟碱含量偏高；气候因素与烤烟化学成分以及可用性关系密切，3个主要气候因子与烤烟化学可用性的关联程度为：气温〉日照〉降水，生育前期气温对烤烟还原糖含量影响较大，糖含量与气温呈正相关，而与日照呈显著负相关。In this article,the characteristics of climate and chemical composition of flue-cured tobacco in 1996 -2006 in Yuxi region including relationships among them were analyzed. The result showed condition of sunlight ＆ temperature ＆ water ＆ heat could meet growth needs of flue-cured tobacco,also it was higher than normal value for content of sugar ＆ nicotine of few leaf. There was a close relationship between climate and chemical composition ＆ usability. The relevance between 3 main factors and usability was temperature 〉 sunshine 〉 precipitation. The atmospheric temperature could exert great influence on content of reducing sugar in earlier growth stage. Positive correlation existed be- tween sugar content and temperature,however negative correlation existed between it and sunshine remarkably.
