截流对烟叶物理性状和吸食品质的影响

Effects of Girdling on Physical Characters and Smoking Quality of Flue-cured Tobacco Leaves

为改进栽培措施、提高烟叶品质,对打顶后的烤烟茎进行截流(环割)处理。结果表明,截流对初烤烟叶物理性状和吸食品质有重要影响。截流可提高中上部烟叶的成熟度,降低中部淡黄烟比率,增加中上部桔黄烟的比率及香气质和香气量,明显改善吃味,提高烟叶的内在品质。

In order to improve cultivation practices and promote leaf quality, the stalk of tobacco plant was girdled after topping. The results showed that the girdling affected physical characters and smoking quality of flue-cured tobacco leaves greatly. The maturity of upper and middle leaves increased, the proportion of light yellow middle leaves was reduced, the proportion of orange upper and middle leaves, aroma quantity and quality were raised, the taste and intrinsic quality of leaves were obviously improved by girdling.
