河北烤烟常规化学成分分析

Analysis on Conventional Chemical Components of Flue-cured Tobacco Leaves in Hebei Tobacco Production Region

对河北烟区139个烤烟样本的内在化学成分进行测定与分析,并与国内优质烤烟和云南烤烟的化学成分进行了比较。结果表明:河北烤烟总氮和总植物碱含量适中,总糖含量与云南烤烟接近,上部叶氯含量偏高,钾含量整体偏低。常规化学成分在年度间差异显著。

The chemical components of 139 flue-cured tobacco samples from Hebei tobacco production region were determined and analyzed,which were compared with the good quality flue-cured tobacco in China and flue-cured tobacco from Yunnan.The results showed that the contents of total nitrogen and alkaloid were appropriate,the content of total sugar was similar with those from Yunnan,the content of chlorine in top leaves was slightly high,while the content of potassium was slightly low.The difference of chemical components among different growth periods was significant.
