摘　　要：[Objective] The aim was to research effects of irrigation quantity and term on winter wheat by wide precision sowing and to provide references and technical supports for water-saving agriculture in North China. [Methed] During 2013-2015, Jimai 22, a winter wheat cultivar, was taken as materials to explore effects of irrigation quantity and term on water consumption characters and yield of winter wheat by wide precision sowing. [Result] As irrigation water increased, water consumption and irrigation water＇s proportions were growing, but quantity and proportion of soil water consumption were both diminishing; seed yields all kept increasing upon irrigation, but water use efficiencies were decreasing. Given the same irrigation conditions, water consumption by wide precision sowing was more, but yield and water use efficiency were higher. [Conclusion] The practice of combining wide precision sowing and irrigation in jointing and flowering stages, based on yield, water use efficiency and economic profits, has the potential to create more yields and higher water use efficiency and suitable to be applied and promtoed in North China.[目的]研究灌溉量和灌溉期对宽幅精播冬小麦的影响，为华北地区节水农业的发展提供理论依据和技术支持[方法]2013～2015年通过田间试验，以高产中筋冬小麦品种济麦22为材料，设宽幅精播和常规种植两种种植方式．研究了不同灌溉量和灌溉时期对宽幅精播冬小玫耗水特性及产量的影响.[结果]随灌水量的增加，农田总耗水量和灌水量占总耗水量的比例也增加，而土壤贮水消耗量及其占总耗水量的比例显著降低；随灌水量的增加，不同种植方式下小麦籽粒产量均有所提高，而水分利用效率（WUE）降低.同一灌溉条件下，与常规种植方式相比．宽幅精播方式的农田总耗水量多，土壤贮水量消耗比例大，籽粒产量较高并具有较高的WUE.[结论]该试验条件下，综合考虑小麦的籽粒产量和WUE,宽幅精播结合灌拔节水＋开花水是华北平原冬麦区较适宜的节种植方式，值得在生产中推广应用.
