To investigate the effects of close planting and water‑nitrogen coupling on the yield of seed maize and its formation process, a three‑factor orthogonal design was employed in this study, with three irrigation levels, three nitrogen application levels, and three planting densities. The regulatory effects of different treatments on agronomic traits, dry matter accumulation, yield components, and yield of seed maize were systematically analyzed. The results showed that different treatments had varying effects on agronomic traits, dry matter accumulation, yield components, and yield of seed maize. Among them, the W₂N₁D₃ treatment exhibited relatively high levels of kernels per row and single ear weight, and achieved the highest yield of 687.95 kg/667m², which was significantly higher than those of the W₃N₂D₁ and W₂N₀D₁ treatments. It was recommended that in this region, an irrigation amount of 250 m³/667 m², nitrogen application rate of 15 kg/667m², and planting density of 85 000 plants/667m² (W₂N₁D₃) be adopted to achieve both high yield and high efficiency in seed maize production.

为探究密植与水氮耦合对制种玉米产量及其形成过程的影响，本研究采用三因素正交设计，设置3个灌水水平、3个施氮水平和3个种植密度，系统分析了不同处理对制种玉米农艺性状、干物质积累量、产量构成要素和产量的调控效应。结果表明：W₂N₁D₃处理行粒数和单穗质量均处于较高水平，且产量达到最高，为687.95 kg/667 m²，显著高于W₃N₂D₁处理和W₂N₀D₁处理。建议灌水量250 m³/667 m²、施氮量15 kg/667 m²、密度8 500株／667 m²（W₂N₁D₃），可实现张掖市制种玉米的高产与高效同步目标。
