探讨浅埋滴灌对春玉米生长发育及产量的影响，实现河西灌区玉米的提质增产与水资源的高效利用。试验研究了浅埋滴灌和覆膜大水漫灌2个处理对春玉米品种金庆707生育期、株高、茎粗、干物质积累量、产量及经济效益的影响。结果表明，与覆膜大水漫灌相比，浅埋滴灌出苗晚3 d，生育期延长5 d；干物质积累量提高3.97%；株高降低5.28%，茎粗增加5.36%，可提高玉米的抗倒伏性；且浅埋滴灌较覆膜大水漫灌玉米产量提高9.25%，百粒重高2.3 g，经济效益提高3 540元/hm2，说明在实际生产当中，浅埋滴灌具有更高的经济效益，节水效果更显著。

To explores the impact of shallow buried drip irrigation on the growth and development of spring maize and its yields, aiming to enhance the quality and output of maize in the Hexi irrigation areas and improve the efficient utilization of water resources, 2 treatments, shallow buried drip irrigation and mulched flood irrigation, were investigated for their effects on the growth period, plant height, stem diameter, dry matter accumulation, yield and economic benefits of the maize variety Jinqing 707. Results showed that compared with mulched flood irrigation, shallow buried drip irrigation delayed emergence by 3 days and extended the growth period by 5 days. It increased dry matter accumulation by 3.97%, decreased plant height by 5.28% and increased stem diameter by 5.36%, indicating that shallow buried drip irrigation can enhance the lodging resistance of maize. Moreover, shallow buried drip irrigation increased maize yield by 9.25%, 100-grain weight by 2.3 g, and net profit by 3 540 Yuan/ha. These findings suggest that in practical production, shallow buried drip irrigation has higher economic benefits and more significant water-saving effects compared to mulched flood irrigation.
