Abstract: The field experiment were carried out to study the effect of different fertilizer application (the quantity of nitrogen was 90.0, 97.5, 105.0 kg/hm2; the ratio of nitrogen, phosphorus and potassium was 1∶1.5∶3.5) on the yield and upper leaves quantity of flue cured tobacco. The results list as followcompared with treatment 1(N 90.0 kg/hm2) and treatment 2(N 97.5 kg/hm2), the yield of flue cured tobacco of treatment 3(N 105.0 kg/hm2) was increased by 11.63% and 6.05%. And the production value of treatment 2 increased by 6.76% and 0.87% compared with treatment 1 and treatment 3, respectively. The superior rate, medium-superior rate and superior rate of upper tobacco of treatment 2 were 48.59%, 91.49% and 60.49%, respectively. With the increase of fertilizer application, single leave weight, stem weight, content of reducing sugar, nicotine, total nitrogen and potassium of flue cured tobacco showed a gradually increasing trend; among which total sugar content of treatment 2 was the highest, while chlorine content was the lowest. In conclusion, when the nitrogen, phosphorus and potassium fertilizer application were 97.5, 146.25, 341.25 kg/hm2 in Lichuan city, higher yield, quality and economic benefits of flue cured tobacco could be achieved.
