The contents of 10 mineral elements in 12 flue-cured tobacco leave samples and cultivated soil samples were detected, and the leaves had different grades of burnt-sweet smelling. The contents of available P in most of the soils were moderate, available K were on the high side. There were no significant difference between the contents of mineral elements of soils in which tobacco leaves having different grades of burnt-sweet smelling. Only Ca, Cu,a 微量矿质元素含量的差异性，仅ith 3579690 Fe and Zn contents of C3F tobacco leaves with middle- grade of burnt-sweet smelling were higher significantly than those with middle grade of burnt-sweet smelling. The results indicated that the effects of mineral element contents in soils and leaves on burnt-sweet smelling grade of flue-cured tobacco leaves were considerably weak and were not the primary cause for resulting in different burnt-sweet smelling grades of flue-cured tobacco leaves.
