| 摘 要： | 为揭示永州烟区烤烟糖、碱空间变异性，为烟区规划和卷烟工业企业原料采购提供指导。针对湖南省永州烟区2007-2009年的C3F等级烤烟样品，采用地统计学方法分析其总糖、还原糖、烟碱含量和糖碱比值的区域特征及空间变异特性。结果表明，永州大部分烟区总糖含量在27.4%～29.2%之间，还原糖含量在25.8%～27.5%之间，烟碱含量在2.4%～2.6%之间，糖碱比在12.1～13.6之间，总糖、还原糖含量及糖碱比在空间分布上均呈从东向西递减的趋势，烟碱含量分布与之相反，呈从西向东递减的趋势。永州烟区植烟县烤烟烟碱含量普遍在湖南省优质烤烟适宜范围内，总糖、还原糖含量除道县西部、江永县北部区域外普遍偏高。

| Abstract: | In order to reveal the spatial variation of sugar,nicotine in Yongzhou Tobacco,and to provide guidance for area planning,procurement of raw materials by tobacco industrial enterprises.In this paper,C3F grade flue-cured tobacco samples were collected in Yongzhou Hunan from 2007 to 2009,The spatial variability of total sugar,reducing sugar,nicotine content and total sugar nicotine ratio were been analyzed by geostatistics.The results showed that the sugar content of tobacco was 27.4%-29.2%,reducing sugar cont... |
