Abstract: In order to clarify the effects of irrigation schedules and varieties on winter wheat yield traits and water use efficiency,4 varieties（Heng 4399,Heng 4444,Hengmai 28 and Shimai 22）are selected from 2020 to 2021,and 5 are set in the field. Water treatment（non-irrigated control treatment-CK,1 water-W1,2 water-W2,3 water-W3,4 water-W4）,each irrigation quota is 75 mm,the ear traits,biomass,yield,components and water use efficiency of winter wheat are studied. The results of the study show that the ear length of winter wheat increases with the increase in irrigation times. The number of fruiting spikelets is the largest in W3 treatment,and the number of infertile spikelets is the smallest in W2 treatment. The proportion of stem biomass to total biomass increases with the increase in irrigation times.The biomass of Heng 4444,Hengmai 28 and Shimai 22 are significantly higher than Heng 4399. The number of ears per unit area of winter wheat increases with the increase in irrigation frequency,which is significantly affected by the irrigation system. In W3 treatment,the 1000-grain weight of Heng 4444,Hengmai 28 and Shimai 22 is the largest in W3 treatment,and Heng 4399 reaches the maximum in W4 treatment. The grain yield of W1,W2,W3,and W4 increases by 68.15% and 98.68 compared with CK treatment. %,120.76% and 136.85%,Hengmai 28 increases by 12.53%,6.33% and 6.55% compared with Heng 4399,Heng 4444 and Shimai 22 grain yield. Heng 4399 reaches the maximum water use efficiency of 2.39 kg/m3in W3 treatment,Hengmai 28 Mai 28,Heng 4444 and Shi Mai 22 reaches the maximum2.49,2.48 and 2.43 kg/m3in W2 treatment. In summary,Hengmai 28 combined with W2 irrigation treatment can achieve higher grain yield and water use efficiency.
