Abstract：To investigate the effcts of wide-furrow sowing combined with fertilizer-water coordination on the yield of winter wheat，a field experiment was conducted during the 2023- 2024 growing season at the experimental demonstration base in Jingyang County，Shaanxi Province.The wheat cultivar‘Bainong 5819’was used to evaluate the effects of diferent irigation frequencies and topdressing timings across growth stages.The results showed that，under adequate seedling irrigation and winter watering，topdressing applied at the regreening stage—where the proportion of phosphate fertilizer exceeded that of nitrogen—produced the highest yields.Compared with other treatments，yield increases ranged from 415 to 1648kg/hm2 ，representing an improvement of 5.1% to 23.6% ：
