Abstract

The experimentwas conducted in Zhengning County,Gansu Province to study the effects of 3414 fertilization program and fertilizer recommendation for flue-cured tobacco.The results showed that the one-factor quadratic models could reflectwell the relationship betweenyield and fertilization rate.The effect functions of Nand Pwere typical models,while the effect function of Kwas a typical model.According to the economic analysis,the optimal application rate of N,P and K for flue-cured tobacco was 56 kg·hm-2,78 kg·hm-2and 270 kg·hm-2,respectively.
