采集了邵阳市主产烟县6个典型产烟乡镇的B2F、C3F、X2F三个等级烤烟样本54个,测定了烟叶总糖、还原糖、烟碱、总氮、钾、氯含量,分析了邵阳市主产烟县烤烟化学成分特征,并应用模糊数学理论对其可用性进行了评价.结果表明:邵阳市烤烟总糖、还原糖、烟碱、总氮、钾、氯含量都处于合理水平,化学协调性好.主要化学成分等级间差异显著,县际间和乡镇间差异不显著.等级间烤烟化学成分可用性指数从高到低依次为:C3F、B2F、X2F.产烟县间以邵阳县烤烟的化学成分可用性最高,隆回县烤烟的化学成分可用性相对较低.乡镇间,B2F、C3F、X2F等级烤烟化学成分可用性指数从高到低分别依次为:马头桥、河佰、下塘云、六...

Characteristics of chemical components of flue-tobacco leaves were studied by detecting total sugar, reducing sugar, nicotine, total nitrogen, potassium and chlorine of 54 samples with 3 grades（B2F, C3F, X2F） from the typical tobacco-growing towns of Shaoyang City, and its usability was evaluated by using fuzzy mathematics. The results showed that： （1）The average concentration of total sugar, reducing sugar, nicotine, total nitrogen, potassium, chlorine were at right levels, and its coordination was good. （2） The concentration difference...
