In order to clarify the regulating effects of different irrigation stages and irrigation times under border irrigation on wheat yield formation and water use efficiency of winter wheat,field experiments were established in 2018-2019 and 2019-2020,and four supplemental irrigation treatments were set up:no-irrigation after emergence(W0),irrigation at jointing stage(W1),irrigation at jointing and anthesis stages(W2),irrigation at rejuvenation,jointing and anthesis stages(W3).The results showed that the spike number and grains per spike of winter wheat increased with the increase of irrigation times under the condition of consistent water management during the sowing period in the two years,and there was a significant difference between treatments. The 1 000-grain weight varied significantly in different years,and it was significantly positively correlated with the amount of pre-anthesis dry matter remobilization.In 2018-2019,the grain yield of W3 treatment reached 10 100.05 kg/ha,with no significant difference compared with W2 treatment,but they were all significantly higher than the other treatments.The grain yield of W3 treatment in 2019-2020 was 9 604.00 kg/ha,significantly higher than other treatments,while the water use efficiency and irrigation benefit were significantly lower than other treatments.There was no significant difference in water use efficiency between W1 and W2,but both were higher than other treatments.Correlation analysis showed that grain yield was significantly positively correlated with post-anthesis dry matter accumulation and contribution of post-anthesis dry matter accumulation to grain.Therefore,irrigation stage and frequency during wheat growing period should be considered in conjunction with the soil moisture during the sowing period and the precipitation in the key growing stages,and supplemental irrigation at jointing and anthesis stages could achieve a synergistic increase of both yield and water use efficiency under the condition of sufficient moisture during the sowing period.
