【Abstract】 Field experiments on the effects of sulfur on the yield and quality of flue\|cured tobacco were conducted in Baofeng, Henan, in 2000 and 2001. The results showed that when the rate of sulfur applied in allurial soils with 10.1mg/kg available sulfur was 60～80 kg/667m 2, the nutrition status and growth of tobacco plant were significantly improved, the yield and output value were increased, appearance quality, and smoking quality of tobacco leaves were also improved.更多还原
