通过对云南26个县(市、区)的主栽烤烟品种‘K326’‘云烟87’‘红花大金元’中部叶烟梗的主要化学成分进行分析。结果表明：烟梗化学成分受环境和栽培条件影响很大，不同品种中部叶烟梗仅总氮和钾含量差异显著，其余化学成分差异不显著；通过聚类分析方法把云南26个烤烟县(市、区)的‘K326’划分为4个类别，分别是高糖低钾区、高糖低氯区、低糖低氯区、低糖高氯区，地域相邻的县(市、区)间烟梗化学成分较相近。

The main chemical components of tobacco stems of ‘K326’,‘Yunyan 87’and ‘Honghuada-j inyuan’from 2 6 flue-cured tobacco regions of Yunnan Province were analyzed and comprehensively evalua-ted.The results showed that the chemical composition of tobacco stems mainly affected by environmental and cultivation conditions,nitrogen and potassium content between different varieties of the middle leaf stem was significant different,the rest chemical composition were not significant.Through cluster analysis, the ‘K326’from 26 flue-cured tobacco regions of Yunnan Province were divided into four categories,high sugar low potassium areas,high-sugar low chlorine areas,low sugar low chlorine areas,low sugar high chlorine areas,the chemical composition between adj acent counties (cities,districts)were similar.
