Abstract: In order to investigate the effect of medium and trace elements, organic fertilizer on appearance and internal qualities of sun-cured tobacco, search after some efficient ways to improve the qualities, by adding organic fertilizer in basal dressing and spraying trace elements on leaf surface, the results showed that both organic and medium or trace fertilizer having the effect of increasing output value and yield. Among the experimental treatments, magnesium fertilizer and manure plus rape cake showed the most. In addition, spraying boric fertilizer decreased nicotine content in leaves by 29.5%, but it changed less in upper leaves when applying organic fertilizer alone. Therefore, it was feasible that applying organic fertilizer under control. Furthermore, applying organic fertilizer improved the smoking quality. At growing age, spraying boric fertilizer with proper amount can reduce nicotine content evidently and improve aroma quality, which giving rise to harmony of chemical composition of tobacco shred and better quality in the round.
