Flue-cured tobacco is extremely sensitive to fertilizer, fertilizer type, dosage and application methods have a significant impact on the yield and quality of flue-cured tobacco. Flue-cured tobacco fertilization principles are: adequate nitrogen fertilizer, nitrogen, phosphorus and potassium ratio of coordination, appropriate amount of base fertilizer, staged top-dressing. Fertilization methods: Production of 667 square meters about 160 kg, generally moderate fertility of tobacco fields, applied to every 667 square meters of pure nitrogen about 10 kg is appropriate. Nitrogen, phosphorus and potassium ratio of 1: 1: 2 ~ 2.5. Among them base
