不同部位烟叶外观特征与内在质量分析研究

Study on Appearance Characters and Internal Quality of Different Stalk Position Flue-cured Tobacco Leaves

要正确区分烟叶等级质量,必须首先分清烟叶的部位。本文通过生产试验,分析了不同部位烟叶的外观特征、内在质量、化学成分和物理特性等方面存在的差异。依据烟叶外观特征表现可正确地判定烟叶部位,从而更好地进行烟叶分级。

Some experiments were carried out to probe into the differences of the appearance characters, internal quality, chemical components and physical traits among the flue - cured tobacco leaves at different stalk position. The results could help for tobacco leaf grading according to the leaf appearance characters.
