摘　　要：对滇中、滇西、滇南及赣南粤东4大烤烟区主要烟叶化学成分含量差异及与气象因素的灰色关联度进行分析。结果表明,4大烟区3个等级烟叶化学成分基本在优质烟的适宜值范围内,说明4个烟区烟叶化学成分协调,是烤烟的优质产区;云南烟区化学成分整体表现差异不显著,而钾含量极显著低于赣南粤东烟区;云南烟区与赣南粤东烟区气象条件的差异主要体现在降雨量及7月平均温度等方面;通过灰色关联度分析,烟叶氯含量与平均全辐射量关联度最大;其他化学指标与6、7月平均温度关系最密切,与降雨量关联度最小。Main chemical component variation and gray correlation between chemical components and meteorological factors in central, west, south Yunnan and south Jiangxi, east Guangdong were analyzed. The results indicated that chemical components of three grade samples were almost in normal range of high quality flue-curod tobacco, which indicated that the flue-cured tobacco in four regions had appropriate content of chemical components, and had high quality. The differences among chemical components flue-cured tobacco in Yunnan were not significant, hut their potassium contents were extremely significantly lower than that in south Jiangxi, east Guangdong. The meteorological differences between Yunnan and south Jiangxi, east Guangdong were precipitation and July average temperature. Through gray correlation analysis, the relevance of chlorin content of flue-cured tobacco with average total radiation was the highest. The other chemical indexes had the highest relevance with June and July average temperature and had the lowest relevance with precipitation.
