[Objective] To provide basic data for tobacco production and quality improvement, the abundance and deficiency of trace elements in tobacco leaves in Honghe tobacco area were studied. [Method] Three hundred C3F grade tobacco leaves were collected from 8 main tobacco producing areas in Honghe prefecture. The contents of copper, zinc, manganese and iron in tobacco leaves were determined according to the agricultural industry standard of the Peoples Republic of China, and the contents of calcium and magnesium were determined according to the tobacco industry standard. [Result] The results showed that the average copper content in tobacco leaves of Gejiu (lS. 36 mg · kg-1) was higher than that of remaining tobacco areas (6 - 15 mg · kg-1); The average zinc content in tobacco leaves of Mengzi (S2. 17 mg · kg-1) and Kaiyuan (S6. 87 mg · kg-1) was higher than that of remaining tobacco areas (20 - 50 mg · kg-1); Except for Pingbian (306. 40 mg · kg-1), Gejiu (2S9. 13 mg · kg-1), Shiping (263. OS mg · kg-1), the average manganese content of tobacco leaves was moderate (SO - 200 mg · kg-1); The average iron content in tobacco leaves of Jianshui was high (177. 74 mg · kg-1), and which of other areas was more than 200 mg · kg-1; The average calcium content in tobacco leaves of the whole area was at a moderate level (1. 7 - 3. 4 mg · kg-1); The magnesium contents in tobacco leaves of Luxi (0. S9 mg · kg-1) and Pingbian (0 . 52 mg · kg-1) were in a moderate level 3/c and the other tobacco areas were low. [Conclusion] In general, the distribution of trace elements in Honghe tobacco leaves varies in different degrees. It was suggested that the fertilization scheme should be readjusted in combination with the situation of the content of trace elements in tobacco leaves in each tobacco area to improve the quality of tobacco leaves.
