摘要
以京冬8号为对照,连续两年对生产中常用的7个小麦品种的田间耗水规律、生物学性状、产量和水分利用效率等指标进行了观测分析,结果表明：小麦拔节期是需水关键期,耗水强度为3.4-4.0 mm/d。京9428和中旱110产量和水分利用效率较高,并表现稳定。京郊小麦在全生育期降水量69~124 mm的条件下灌三水可保证较高产量。
With Jingdong No.8 as control,the soil water consumption,root development,yield,WUE,etc.of 7 varieties of winter wheat were studied for two years.The results showed that reviving～jointing stage was critical to wheat,and the consumption rate is 3.4～4.0 mm/d.Jing 9428 and Zhonghan 110＇s yield and WUE were higher and stable compared to the control.In Beijing＇s climate condition,three times irrigation during the whole growth period is necessary for relatively high yield of winter wheat.
