为了科学补充烟田微量元素，平衡烟株营养，改善烟叶质量，为百色烤烟生产提供理论依据，在百色烟区烤烟主产县选取了236个土壤样品，分析了该区土壤有效态微量元素含量状况。结果表明，百市植烟土壤中有效铜、锌、铁、锰等微量元素含量较丰富和极其丰富，有效硼、钼、氯含量较大面积缺乏。因此，在生产过程中增施硼肥和钼肥，提高土壤硼、钼含量；慎重使用氯肥（如氯化钾），最好施用加有氯肥的烟草专用复合肥，使烟叶氯含量达到适宜范围。

In order to supply micronutrients to tobacco field, balance nutrition of tobacco plant ,improve the quality of tobacco, and provide scientific basis for tobacco production in tobacco of Baise, selecting 236 soil samples from the main tobacco-growing counties in Baise, this study analyzed available microelement contents in the area. The results indicated that the available contents of Cu, Zn, Fe and Mn in tobacco of Baise was high or quite rich .However, there were less B, Mo, Cl in tobacco-planting soils. Therefore, it is necessary following the principles such as increasing application of B and Mo fertilizer will improve soil boron and molybdenum content, respectively. It should be application chlorine fertilizer with caution (such as potassium chloride), and it is a best method that application of tobacco-specific compound fertilizer containing chlorine fertilizer, which make the content of chlorine reach the appropriate range in tobacco leaves.
