广西初烤烟叶的微量元素含量分析研究

目的]研究广西2个烟区初烤烟叶微量元素的丰缺状况。方法]对广西贺州富川和百色靖西2个烟叶主产区109个初烤烟叶微量元素含量进行分析。结果]结果表明,富川及靖西烟区初烤烟叶中铜、锌、硼元素含量处于适中水平,铁元素含量处于高水平;富川烟区锰元素的含量处于适中水平,而靖西烟区则处于较低水平;微量元素随着烟叶部位的不同呈一定的规律,铁元素的含量分布随烟叶部位上升而下降,铜、硼、钼元素的含量分布则随烟叶部位上升而上升。结论]研究可为烟叶产区的合理施肥,以及进一步提高烟叶产量及质量提供参考依据。

Analysis of Microelements in Flue-Cured Tobacco Leaves from Guangxi

Objective ] To study flue-cured tobacco microelemcnts in Guangxi. Method ] The mieroelements content in 109 flue-cured tobacco from Fuchuan and Jingxi, Guangxi Province were analyzed. Result] The results showed that the content of copper, zinc and boron were modest and the content of iron element was high in both areas. However, the content of manganese was modest in Fuchuan but low in Jingxi. At the same time, the results indicated the relationship between element content and stalk position. As the stalk position increased, the content of copper, bo- ron and molybdenum increased, while the content of iron decreased. Conclusion ] The study can provide reference basis for proper fertilizing and further improve tobacco quality and yield.
