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%.
