Abstract:

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.
