摘要
对在2002-2005年间洛阳地区的70个烤烟样品进行了常规化学成分分析,结果表明:烤烟总氮、钾、氯、淀粉含量基本适宜,还原糖、烟碱、糖/碱、氮/碱、钾/氯等变异范围较大,部分样品烟叶烟碱、还原糖含量偏高;各化学成分间相互比例基本协调,少数烟叶化学成分比例不够协调甚至失衡。
The chemical components of 70 flue-cured tobacco samples in 2002~2005 are analyzed.The content of TN, K2O,Cl-1and starch on flue-cured tobacco produced in Luoyang area are fundamentally proper.Variation range of its reducing sugar,nicotine,RS/Nic.,TN/Nic.,K2O/Cl-1 etc. is larger.Content of nicotine and reducing sugar of some samples is higher.Mutual proportions of chemical ingredients in tobacco leaves are in harmony fundamentally,but a few is less harmonious or unharmonious.
