| 摘 要： | 分析了曲靖烟区土壤pH值与烟叶总糖、还原糖含量的变化趋势,结果表明:曲靖烟区烟叶的总糖含量为314.69g/kg,还原糖含量为237.42 g/kg。曲靖烟区不同等级烟叶总糖、还原糖含量高低顺序为C3F>X2F>B2F。土壤pH值与烟叶总糖、还原糖的关系非常密切,但并非简单的直线关系,土壤pH值过高或过低均不利于烟叶总糖、还原糖的形成和积累。

| Abstract: | The change trend of pH-value of soil,and total sugar and reducing sugar content of tobacco leaves in Qujing tobacco-growing areas was analyzed in this study.The results showed that the content of total sugar and reducing sugar was 314.69 g/kg and 237.42 g/kg,respectively.The order of total sugar and reducing sugar content in different grades of flue-cured tobacco leaves was C3F>X2F>B2F.There was close relationship between soil pH-value and tobacco total sugar and reducing sugar content.However,it was not a simple linear relation.It was not good for sugar formation and accumulation when soil pH-value was too high or too low. |
