探讨不同施肥方式对新乡市小麦增产效果及肥料利用率的影响,可为豫北小麦高产区合理施肥提供理论依据。采用田间氮、磷、钾肥丰缺施肥试验,研究了不同施肥处理对新乡市小麦产量以及氮、磷、钾肥吸收量与利用效率的影响。结果表明：N210P90K90处理的小麦产量和氮、磷、钾肥吸收量均最高,分别较不施肥处理（CK）提高了33.19%和48.49%、42.75%、36.42%;其氮、磷、钾肥利用率和偏生产力也均最高,分别为20.65%、20.09%、36.96%和30.27 kg/kg、70.62 kg/kg、70.62 kg/kg。氮、磷、钾肥配合施用有助于促进小麦对养分的吸收,提高肥料利用率,发挥各肥料对小麦的增产潜能,实现小麦高产高效的目标。

To provide the theoretical basis for reasonable fertilization of wheat in North Henan, the effects of different fertilization treatments on the yield, nutrient uptake amount and fertilizer use efficiency of wheat were studied in Xinxiang by using the fertilizer sufficiency or deficiency experiments in field. The results showed that the wheat yield and N, P and K uptakes amounts were the highest with N210 P90 K90 treatment, which increased by 33.19% , 48.49% , 42. 750/0 and 36.42% , respectively, N, P and K fertilizer use efficiency was the highest, which was 20. 65% , 20. 09% and 36. 96% , respectively, and the partial factor productivity was 30.27 kg/kg, 70.62 kg/kg and 70.62 kg/kg, respectively. The reasonable application of N, P and K fertilizer could enhance the uptake rate, increase the fertilizer use efficiency, develop their potential on increasing wheat yield, and achieve the goal of high yield and efficiency of wheat.
