Abstract: With winter wheat cultivar Nongda 3291,field trial containing irrigation operation,nitrogen application amount and sowing rate was carried out at Wuqiao experimental station of Hebei province.The results of this experiment revealed: as compared with two irrigation in spring,four irrigation can increase 1.78 g of 1000 grain weight and grain yield by 665.1 kg/ha of grain yield in winter wheat.While water consumption under four irrigation plot had 73.65 mm more than those under two irrigation one,and water utilization efficiency was decreased by about 7.63%.

Key words: Irrigation operation, 1000-grain weight, Grain yield, Winter wheat
