2011~2012年在12个省份采集129份烟叶样品,检测其物理指标和常规化学成分含量。数据统计结果显示,烤烟产地对烟叶的单叶重、含梗率、平衡含水率、抗张强度、叶片厚度、填充值都有较大的影响;烤烟等级对烟叶的单叶重、含梗率、平衡含水率、叶片厚度、填充值5项指标有较大的影响。由此得出,烤烟产地与烟叶物理特性关系更为密切;烟叶单叶重、厚度与烟叶常规化学成分关系密切。
129 tobacco samples were collected in 12 provinces from 2011 to 2012, and their physical indexes and routine chemical components were tested. Data statistics show that the origin of flue-cured tobacco has a greater impact on the single leaf weight, the peduncle ratio, the equilibrium moisture content, the tensile strength, the leaf thickness and the filling value of tobacco leaves. The flue- , Balanced moisture content, leaf thickness, fill value of 5 indicators have a greater impact. It is concluded that the origin of flue-cured tobacco is more closely related to the physical characteristics of tobacco leaf. The leaf weight and thickness are closely related to the conventional chemical components of tobacco leaf.
