水氮运筹对玉米产量及水氮利用效率的影响

【目的】确定适合豫北灌溉区玉米的高产高效和节水增效的水氮运筹模式。【方法】采用随机区组设计实施了为期3 a 田间定位试验,试验设置3个灌水量:灌0水(A1),灌2水(A2)和灌3水(A3);2个氮肥运筹:B1:基肥(70%)+小喇叭口期(20%)+灌浆期(10%),B2:基肥(60%)+小喇叭口期(25%)+灌浆期(15%),共6个处理,并分析灌水次数和氮肥运筹对玉米产量和水氮利用效率的影响。【结果】灌水次数(A)和氮肥运筹(B)对玉米产量、水分利用效率(WUE)、灌水利用效率(IWUE)和氮肥偏生产力(NPFP)的影响均极显著,而A×B交互作用对其没有显著影响。2017年和2019年玉米产量...

description 【目的】确定适合豫北灌溉区玉米的高产高效和节水增效的水氮运筹模式。【方法】采用随机区组设计实施了为期3 a 田间定位试验,试验设置3个灌水量:灌0水(A1),灌2水(A2)和灌3水(A3);2个氮肥运筹:B1:基肥(70%)+小喇叭口期(20%)+灌浆期(10%),B2:基肥(60%)+小喇叭口期(25%)+灌浆期(15%),共6个处理,并分析灌水次数和氮肥运筹对玉米产量和水氮利用效率的影响。【结果】灌水次数(A)和氮肥运筹(B)对玉米产量、水分利用效率(WUE)、灌水利用效率(IWUE)和氮肥偏生产力(NPFP)的影响均极显著,而A×B交互作用对其没有显著影响。2017年和2019年玉米产量、WUE和NPFP的变化规律为A3B2处理>A2B2处理>A3B1处理>A2B1处理>A1B2处理>A1B1处理;而2018年玉米产量和NPFP为A3B2处理>A3B1处理>A2B2处理>A2B1处理> A1B2处理>A1B1处理,WUE为A3B2处理>A3B1处理>A2B2处理> A1B2处理>A1B1处理>A2B1处理,且2017—2019年A3B1处理玉米产量、WUE和NPFP与A2B2处理间没有显著性差异。与对照(A1B2处理)相比,2017—2019年A3B2处理玉米产量、WUE和NPFP分别增加20.2%~39.6%、4.8%~10.9%和20.2%~39.6%。2017—2019年玉米IWUE均随着灌水次数的增加而降低,其中均以A2B2处理最高,较A3B2处理增加30.2%~91.9%。此外,2017—2019年A2B2处理玉米产量和NPFP显著高于A1B2处理,分别增加11.3%~21.1%和11.3%~21.2%。【结论】A3B2处理为豫北灌区玉米最佳高产高效模式,A2B2处理为豫北灌区玉米最佳节水增效模式。
