| 摘 要： | 分析了云南19个县(市、区)烤烟品种K326的X2F、C3F、B2F 3个等级烟叶主要化学成分特点,并对C3F等级烟叶化学成分进行综合评价.结果表明,云南烟区烤烟化学成分的平均值基本都在优质烟的适宜值范围内,各项化学成分协调,是烤烟的优质产区；通过对C3F等级烟叶化学成分进行聚类分析,将云南烟区划分为4类,即高氯低钾区、高钾低碱区、高糖低氯区、高碱低糖区,其中第2类和第3类烟区烟叶品质较好,主要分布在新平县、耿马县、马龙县、景东县和禄丰县. |

| Abstract: | The main chemical components of X2F,C3F,B2F leaves of flue-cured tobacco K326 from 19 tobacco regions of Yunnan province were analyzed and comprehensively evaluated.The result indicated that the average chemical components of flue-cured tobacco samples in Yunnan were almost in normal range of high quality flue-cured tobacco,which indicated that the flue-cured tobacco in Yunnan had appropriate content of chemical components,and had high quality.By systematically clustering on C3F,the tobacco regions of Yunnan were divided into four sub-regions of high chlorin-low potassium areas,high potassium-low nicotine areas,high sugarlow chlorin areas,and high nicotine-low sugar areas.The quality of tobacco leaves of the second and third sub-regions performed better,which included Xinpin county,Gengma county,Malong county,Jingdong county and Lufeng county. |
