摘要
采集了永州市10个典型产烟乡镇的B2F、C3F、X2F 3个等级烤烟样本150个,测定了烟叶总糖、还原糖、烟碱、总氮、钾、氯含量,分析了永州市烤烟化学成分特征。结果表明:永州市烤烟总糖、还原糖、总氮、钾含量都处于合理水平,上部烟叶烟碱含量略偏高,部分烟叶氯含量较低。常规化学成分年度间差异显著,县际间和乡镇间差异不显著。聚类分析将永州市10个典型产烟乡镇分为高糖和低糖2个类型。
The characteristics of chemic al components of flue-tobacco leaf were studied by detecting total sugar, reducing sugar, nicotine, total nitrogen, potassium and chlorine of 150 flue-tobacco samples with 3 grades （B2F, C3F, X2F） from 10 typical tobacco-growing towns of Yongzhou city. The results showed that total sugar, reducing sugar, total nitrogen, potassium were at right levels, nicotine was slightly high in top leaf and chlorine was slightly low in some samples. The concentration difference of chemical components in tobacco samples between grown years was significant, but that between tobacco-growing counties and towns was not statistically significant. The main chemical components of flue-cured tobacco leaves in 10 typical tobacco-growing towns of Yongzhou city were divided into 2 types （high sugar content and low sugar content） by the cluster analysis.
