摘 要:[目的]为研究氮肥、磷肥、钾肥对夏玉米产量和经济效益的影响和测土配方施肥提供依据。[方法]在河南省鹤壁市利用"3414"试验设计,布置夏玉米氮、磷、钾肥料效应试验。[结果]氮的缺乏对夏玉米产量影响最大,其次为磷,最后为钾。[结论]施肥量推荐类型:夏玉米目标产量〉10 500 kg/hm^2,氮磷钾配比用量18∶8∶6;夏玉米目标产量9 000-10 500 kg/hm^2,氮磷钾配比用量为16∶6∶4;夏玉米目标产量9 000 kg/hm^2以下,氮磷钾配比用量为14∶4∶2。[ Objective ] The research aimed to provide the basis for the study of the influence of nitrogen, phosphorus and potassium fertilizer on summer corn yield and economic benefit and soil testing and fertilizer. [ Method] In Hebi City, Henan Province, "3414" experiment design was used to arrange the fertilizer effect experiment of nitrogen, phosphorus and potassium. [ Result] N loss had the greatest influence on summer corn yield, followed by phosphorus, finally to potassium. [ Conclusion] Fertilizer recommendation types were as follows: when summer corn production target was 〉 10 500 kg/hm^2, N, P, K ratio was 18: 8: 6; when summer corn production target was 9 000 - 10 500 kg/hm^2, N, P, K ratio was 16: 6: 4; When summer corn production target was 9 000 kg/h m^2, N, P, K ratio was 14: 4: 2.
