为研究安丘市洋葱对氮、磷、钾肥的肥效反应和适宜用量,采用“3414”试验方案设计,研究肥料配施对洋葱产量的影响及最高产量和最佳经济效益时氮、磷、钾肥的推荐施用量。结果表明,氮、磷、钾肥配施可显著提高洋葱产量,最大增产率达103．99%。氮、磷、钾肥间存在明显的交互作用,各因素对洋葱产量的影响顺序为钾>氮>磷,高量处理均表现为产量减少。经回归模型的拟合表明,本试验不适合用三元二次肥效模型；二元二次和一元二次肥效模型可较好地表达施肥量与产量间的关系。通过肥效模型计算可知,洋葱达到最高产量时氮( N)、磷( P2 O5)、钾( K2 O)的施入量分别为1443．4、2359．4、1632．0 kg/hm2,达到最佳经济产量时氮( N)、磷( P2 O5)、钾( K2 O)的施入量分别为1343．2、1852．3、1400．2 kg/hm2。

The “3414” experiment was designed to study N, P, K fertilizer combined application effects on Allium cepa L. yield and the optimum fertilizer recommendation rates when reached the maximum yield and the optimum economic yield in An-qiu area. The results showed that the application of N, P, K fertilizer could significantly increase the yield of Allium cepa L. , with a largest increase rate of 103. 99%. The combined application of N, P, K fertilizer had significant interactions with each other and increased the yields with the order of K > N > P, while yield of the treatments of high fertilizer application levels showed a decreasing trend. Based on the fertilizing model, the fertilizer quadratic model was not suitable for this test. Through the appropriate fertilizer models based on the yields, it could be concluded that for the Allium cepa L. the maximum yield could be reached when N, P2 O5 , K2 O were applied with 1 443. 4, 2 359. 4, 1 632. 0 kg/hm2 respectively, and the optimum economic yield could be achieved with 1 343. 2, 1 852. 3, 1 400. 2 kg/hm2 respectively.
