摘要:
【目的】 研究氮磷钾(NPK)肥配施对冬小麦产量和品质的影响,并分析其肥料效应,探明小麦高产、优质、高效的最佳NPK施肥量和施肥配比,为提高小麦的施肥效率提供科学依据。【方法】 以冬小麦品种新冬42号为材料,采用“3414”肥料效应设计方案,设置田间小区试验,测定冬小麦产量和品质相关性状并进行肥料效应模型拟合。【结果】 氮磷钾肥对产量的影响有互作效应,互作效应大小依次为NPK>NP>NK>PK。14个处理中,N2P2K2处理的冬小麦产量和经济效益最高,分别为8 036.03 kg/hm2和18 044.85元/hm2。氮、磷、钾施用量分别为190.21、122.27和53.11 kg/hm2时,冬小麦产量最大,为8 082.75 kg/hm2;氮、磷、钾施用量分别为171.03、108.18和44.77 kg/hm2时,冬小麦经济效益最佳,为18 056.37元/hm2;氮、磷、钾施用量分别为180.00、125.69和50.90 kg/hm2时,淀粉干基含量最大,为5 742.29 kg/hm2;氮、磷、钾施用量分别为274.64、69.75和138.95 kg/hm2时,湿面筋含量最大,为2 766.20 kg/hm2。【结论】 合理施用氮磷钾肥可以显著提高新冬42号的产量、品质和经济效益。
