Special compound fertilizer for tobacco and application method thereof

The invention discloses a special compound fertilizer for tobacco and an application method thereof. A granular compound fertilizer is prepared by mixing, stirring and crushing 2 to 10 mass percent of urea, 5 to 20 mass percent of ammonium phosphate fertilizer, 5 to 15 mass percent of potassium nitrate, 10 to 30 mass percent of potassium sulfide, 0 to 15 mass percent of lignosulfonate, 0 to 20 mass percent of coal, 5 to 20 mass percent of attapulgite and 0 to 2 mass percent of borax and performing granulation, drying, cooling and screening, and is doped and uniformly mixed with 0 to 5 mass percent of granular lime nitrogen to prepare a special compound fertilizer finished product for tobacco, and the compound fertilizer finished product is matched with other fertilizers for application 5 to 15 days before the transplantation of tobacco seedlings. The formula of the special compound fertilizer for tobacco has high practicability for southern tobacco areas, and the serious problems of soil acidification and the like caused by conventional fertilizer application formula can be solved; in addition, certain amounts of medium trace elements and synergist are added in the formula, so that requirements on mineral nutrition in a tobacco plant development process can be met, the utilization rate of nutrition is increased, the number of fertilizer application times is reduced, and the yield of tobacco plants and the quality of tobacco leaves are remarkably improved.
