摘　　要：为探究华北平原冬小麦水肥一体化节水高产种植模式,以泰科麦33和山农29小麦品种为试验材料,于2017-2018年冬小麦生育期进行大田试验。试验以常规施肥沟灌处理为对照(F1),设置F2、F3、F4水肥一体化3个处理,对冬小麦群体动态变化、株高和产量进行测定。结果表明,水肥一体化条件下施氮量225kg/hm^2有利于增加春季冬小麦最大分蘖数及株高。同时,水肥一体化条件下施氮量225 kg/hm^2提高了泰科麦33的穗数和穗粒数和山农29的穗数和千粒重,从而显著提高冬小麦产量。The field test conducted in wheat growth period during 2017-2018 was aimed to explore the water-fertilizer integrated water-saving and high-yielding planting mode for winter wheat in the North China Plain. The wheat varieties of Taikemai 33 and Shannong 29 were used as materials. With the furrow application of conventional fertilizers( F1) as control,three water-fertilizer integrated treatments( F2,F3 and F4) were set to determine the population dynamics,plant height and yield of winter wheat. The results showed that the application of 225 kg/hm^2 nitrogen under the condition of water and fertilizer integration was benefit to increasing the maximum spring tillers and plant height of winter wheat,and increased the spike number and kernel number per spike of Taikemai 33 and the spike number and 1 000-grain weight of Shannong 29. Thus the winter wheat grain yield increased significantly.
