By improving the effectiveness of the fertilizer, the application amount of the special compound fertilizer for tobacco is reduced by 0.5-1.0 g/plant, meanwhile, the flue-curing resistance of tobacco leaves is improved, the ecological environment of a tobacco area is protected, meanwhile, the special fertilizer for flue-cured tobacco is applied into soil in a centralized and layered mode, soil fixation is reduced, the fertilizer utilization rate is improved, it is ensured that tobacco plants absorb and utilize N: P2O5: K2O nutrients, and the tobacco yield is improved. Therefore, the fertilizer utilization rate and the baking resistance of tobacco leaves are obviously improved, and high-quality production of flue-cured tobacco is guaranteed.
