湖南省桂阳县烟叶物理特性分析与综合评价

Analysis and Comprehensive Evaluation of Physical Properties of Tobacco Leaves from Guiyang County of Hunan Province

为明确湖南省桂阳县烟叶物理特性的区域特征,以桂阳县2013年烟叶样品为材料,对不同等级、品种和乡镇的烟叶的物理特性进行了分析和综合评价。结果表明:桂阳县烟叶开片度较好,平衡含水率略低,中部烟叶身份适中、结构疏松,但部分上部烟叶样品含梗率偏高、单叶重偏大、叶片过厚、叶质重偏大。桂阳县中部烟叶物理特性显著优于上部烟叶;上部烟叶以云烟87的物理特性较优,中部烟叶以湘烟3号的物理特性较优;上部烟叶以方元乡物理特性最好,其次是银河乡,正和乡较差;中部烟叶以流峰乡物理特性最好,其次是仁义乡,银河乡较差。

In order to explicit the regional features of physical properties of flue -cured tobacco leaf in Guiyang County, the physical properties of different grades,different varieties and different towns were analyzed with the flue -cured tobacco samples of 2013 from Guiyang County.The results showed that the tobacco of Guiyang had better leaves proportion,lower e-quilibrium moisture content,moderate body and loosen leaf construction in middle leaf,slightly higher stem ratio and slight-ly bigger weight per leaf and slightly bigger thickness of leaf and slightly bigger weight per unit leaf area.The physical properties of middle flue -cured tobacco leaf was superior to upper leaf.The physical properties of upper flue -cured to-bacco leaf of Yunyan 97 was better than Xiangyan 3,and that of middle flue -cured tobacco leaf of Xiangyan 3 was better than Yunyan 97.The physical properties of upper flue -cured tobacco leaf from Fangyuan village was the best,the nxet from Yinhe village,and the poorer from Zhenghe village.The physical properties of middle flue -cured tobacco leaf from Liufeng village was the best,the nxet from Renyi village,and the poorer from Yinhe village.
