为明确小麦在冬季干旱年份的水分运筹方式，于2010-2011年采用随机区组试验设计对4个小麦品种进行了12个灌水方式的小麦产量试验，结果表明，冬春干旱年型，增加灌水次数可实现小麦增产1200～4200 kg/hm2，冬前灌溉分蘖水、越冬水的产量明显高于春季灌水，其中以早灌分蘖水的小麦产量较高，早灌起身水可较延迟灌水小麦产量提高3％，全生育期小麦灌溉分蘖＋拔节＋开花＋灌浆4水的产量最高，灌溉越冬＋拔节＋开花＋灌浆的产量次之，而灌溉分蘖/越冬＋拔节＋开花3水的小麦产量可达到或超过春后4水的产量，但从节水角度，实现小麦的高产应以灌水3次为宜，可同步实现小麦的高产和高水效的统一。不同品种对灌水处理的反应存在较大差异，衡4399旱作产量较高，稳产性好，济麦22和冀585增加灌水产量增加明显，具有较高的丰产性。

With the method of randomized block design , four wheat cultivars with 12 irrigation methods were used to study irrigation application regime in drought year of 2010-2011 .Results indicate the yield of wheat with more irrigations raised 1 200-4 200 kg/ha comparing to dry farming ,a significantly higher grain production in tille-ring and overwatering irrigation was achieved than that irrigated in spring and with more yield in tillering irrigation , while more than 3%yield of wheat was obtained with rose water but delayed water .Irrigation in tiller+jointing+anthesis+grain filling stage and overwintering +jointing+anthesis+grain filling stage during the whole growth pe-riod have the first and the second yield ,respectively .Three times irrigations in tiller/overwinter+jointing+anthesis stage can have closed to or exceed yield than that of four times watering in spring .However , unification of higher yield and higher water use efficiency was achieved with 3 times water .There was a significant difference of the re-sponses to irrigation treatment among cultivars ,a stable yield with higher yield was gained with H 4399 in dry farm-ing,JM22 and J585 had a remarkable increased yield with added water ,which show a good productivity .
