对泸州烟区两种主要土壤类型上的4个主要烤烟品种的化学成分进行了分析,并将其与国内外其它烟区的烤烟化学成分进行了比较分析。结果表明:泸州烟区烤烟化学成分含量较适宜,其中糖类含量较高,烟碱含量较适宜,钾含量偏低,整体上化学成分组成比例较协调;与国内外其它烟区烤烟相比,泸州烟叶的总糖、还原糖含量仅次于云南和津巴布韦的烟叶,且糖碱比较高,烟碱含量各地区差异不明显,整体上泸州烟叶含量处于中间水平,钾含量较低,仅高于会理,烟叶氯含量高于云南、重庆、湖北,但稍低于适宜水平;经聚类分析,可以把泸州烟区与国内外其它几个烟区的下部叶、中部叶、上部叶的化学成分各分为两类。
The chemical constituents of four major flue-cured tobacco varieties in two major soil types in Luzhou tobacco growing area were analyzed and compared with the chemical compositions of flue-cured tobacco in other tobacco growing areas at home and abroad. The results showed that the content of chemical components in flue-cured tobacco in Luzhou tobacco-growing area was more suitable, including higher content of sugars, nicotine content, lower potassium content, and overall coordination of the chemical composition. Compared with flue-cured tobacco in other areas at home and abroad, The total sugar and reducing sugar contents of Luzhou tobacco were second only to those of Yunnan and Zimbabwe, and the contents of nicotine and nicotine were not obvious. The content of Luzhou tobacco was at the intermediate level and the content of potassium was lower than that of Luzhou Huaiyin had higher chlorine content than Yunnan, Chongqing and Hubei, but slightly lower than the appropriate level. According to the cluster analysis, the chemical compositions of the lower leaves, the middle leaves, the upper leaves The ingredients are divided into two categories.
