| 摘 要： | 以曲靖市沾益县不同地形条件下的烟叶为研究对象,采集烟样681份,进行了土壤养分及烟叶化学成分的测试分析,研究了地形条件对沾益县烟叶化学成分的影响。结果表明:沾益县不同地形土壤养分差异较明显。地形条件对上部烟叶各化学成分含量的影响不明显,对中部烟叶总糖、还原糖、总氮的含量以及下部烟叶总糖和还原糖的含量影响明显。其中山地中部烟叶和下部烟叶总糖和还原糖的含量均较高,中部烟叶总氮含量最低。

| Abstract: | In order to know the impacts of terrain conditions on chemical compositions of tobacco leaves,681 tobacco samples were collected from Zhanyi County,and soil nutrient and chemical compositions of them were analyzed.The results showed that different terrains in Zhanyi County had obvious differences in soil nutrient;terrain condition had not obvious influences on each chemical composition content of upper leaves,but had significant influences on contents of total sugar,reducing sugar and total nitrogen in middle leaves,and also had significant influences on contents of total sugar and reducing sugar in lower leaves,in which the contents of total sugar and reducing sugar in middle and lower leaves from mountain area were high,and the content of total nitrogen in middle leaves from mountain area was the lowest. |
