| To study the method of improving crop yield in sprinkler irrigation, a field experiment was conducted at the high\|standard farmland during the growing season of winter wheat in 2024. The fertilizer movement in the soil and the crop growth were compared among treatments with three NPK ratios (1∶0.55∶0.17, 1∶0.55∶0.30, 1∶0.68∶0.30) and three fertigation water amounts (38.5 mm, 60.5 mm, 82.5 mm) at the jointing stage of winter wheat. The results showed that the water\|mediated transport capacity of nitrogen, phosphorus, and potassium fertilizers follows the order: nitrate nitrogen > available potassium > available phosphorus. When the fertigation water amount ranged from 38.5 to 82.5 mm, the transport depths of nitrate nitrogen, available potassium, and available phosphorus were 30-100 cm, 40-80 cm, and 30-40 cm, respectively. There were no significant differences in SPAD value, plant height, leaf area index, and nitrogen uptake components among all treatments. However, compared to other treatments, the treatment with the highest P fertilizer ratio and the largest water amount achieved significantly higher dry matter above ground, spike per acre, water consumption, and yield, the maximum increases were 23.0%, 26.2%, 10.7%, and 17.0%, respectively. Furthermore, the maximum increase in WUE was 5.1%. Therefore, the method of increasing the phosphorus ratio (0.68) and the fertigation water amount (82.5 mm) at the jointing stage could be recommended as a sprinkler fertigation strategy for increasing yield in high\|yield winter wheat fields. |
