中文摘要:

为了探讨“3414”方案在烤烟施肥中的应用和正宁县烤烟的合理施肥量，通过田间试验研究了正宁县烤烟“3414”方案的施肥效果和推荐用量。结果表明，当三元二次肥效模型不能对“3414”试验结果进行拟合时，采用一元二次肥效模型拟合，可以较好地反映产量与施肥量之间的关系；氮、磷肥效应函数属典型模型，钾肥效应函数属非典型模型；结合经济效益分析，可以看出本试验条件下当地烤烟种植的经济最佳氮、磷和钾施用量分别为56 kg·hm^-2、78 kg·hm^-2和270 kg·hm^-2。

英文摘要:

The experiment was 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 reflect well the relationship between yield and fertilization rate. The effect functions of N and P were typical models, while the effect function of K was 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^-2 and 270 kg·hm^-2, respectively.
