摘要： 通过对2005、2007年湖南省桂阳县和平镇和桥市乡两个地区不同部位的烟叶样品的测定分析，将2007年桂阳地区烟叶中部分中微量元素含量与2005年该地区烟叶中微量元素含量以及将桂阳烟叶中中微量元素与津巴布韦烟叶进行对比，结果表明：与2005年相比，2007年桂阳地区烟叶中硼、铁、铜的含量明显降低，处于较低水平，锰的含量有所下降，但是仍在适宜范围，个别部位烟叶中镁和钙的含量略有下降，仍处于较低水平。与津巴布韦烟叶相比，桂阳地区烟叶中B、Fe，Cu的含量较低。

Abstract: Abstract: In order to study on the changing condition of some contents of the medium and trace elements in tobacco leaves in Guiyang area in recent years, detected the medium and trace elements contents of different positions of tobacco leaves at Heping and Qiaoshi townships of Guiyang area in 2005 and 2007 with the methods of ICP and compared with that of Zimbabwe. The results showed that, compared with that in 2005, the contents of B, Fe and Cu were decreased evidently and were at a lower level in 2007, and at the same time the content of Mn was slightly lower but with a moderate content. Compared with the tobacco leaves of Zimbabwe, the tobacco leaves of Guiyang area were poor in B, Fe and Cu. The study suggests to increase the application amount of the medium and trace elements in Guiyang area.
