| 摘 要： | 依据天长市二峰灌溉试验站2010年夏玉米地下水位埋深试验资料，通过6种地下水位控制处理和3种对照夏玉米试验，探讨了不同地下水位埋深对夏玉米的耗水量及耗水量与产量关系的影响。结果表明：夏玉米的耗水量呈抛物线型，前后期小，中期大，到抽雄吐丝期达到最大，并随水位埋深加大而降低；过高或过低的耗水量均影响夏玉米的产量。

| Abstract: | A field experiment was conducted at Erfeng Irrigation Experiment Station of Tianchang in 2010to evaluate the effect of different groundwater levels management on water consumption and yield of summer maize.The groundwater level management consisted of six groundwater levels control set and three free water levels.The results showed that the daily water demand in the whole growth period appeared to be a parabola,and was low in early and later stage,high in middle stage,maximum at tassel emergence stage.The water consumption decreased with the increase of groundwater depth.The water consumption has effect on the yield of summer maize. |
