| 中文摘要: |
| 2023-2024年度在陕西省泾阳县试验示范基地进行小麦宽幅沟播肥水匹配试验，以百农5819为参试品种，研究了不同浇水次数、不同生育期追肥对小麦产量的影响。结果表明：在保证出苗水和冬灌的基础上，返青期进行追肥，追肥比例磷肥大于氮肥的处理产量最高，较其它处理增产415~1 648 kg/hm2，增幅5.1%~23.6%。 |
| 英文摘要: |
| To investigate the effects 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 different irrigation 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 1 648 kg/hm2, representing an improvement of 5.1% to 23.6%. |
