| 2008年6～9月在河南新乡进行了不同沟灌方式和水分处理下（质量比占田间持水率的80%、70%、60%）夏玉米生理特性和生产效率的试验研究。结果表明：交替隔沟灌溉有效抑制冗余生长，使光合产物向有利于产量形成方向运转，灌水量均减小33.3%，耗水量降低22.04%、21.05%和23.88%，减产2.85%、3.99%和9%；常规沟灌和交替隔沟灌溉的灌溉水生产效率(WUEI)均是70%处理最高，为1.74和2.50 kg/m3，总水分生产效率(WUEET)表现为常规沟灌70%处理最高（1.63 kg/m3），交替隔沟灌溉80%处理最高（2.05 kg/m3）；同种水分处理，交替隔沟灌溉的水分生产效率远高于常规沟灌，是
夏玉米适宜的供水模式。 |

| A study was made from June to September 2008 on the physical properties and water use efficiency of summer maize under treatments of different furrow irrigation and processing of water (80%, 70% and 60% of field water holding) on each application and frequency in Xinxiang of Henan Province. The experimental results show that controlled alternative furrow irrigation can effectively inhibit the growth of maize redundancy, so it is conducive to make photosynthetic production to the direction of yield formation; the irrigation amount is decreased by 33.3%, water consumption decreased by 22.04%, 21.05% and 23.88%, while the yield decreased by 2.85%, 3.99% and 9%; WUEI of conventional furrow irrigation and alternate furrow irrigation are the highest in treatment 70%, 1.74 and 2.50 kg/m3 in each irrigation; WUEET shows that 70% treatment for CFI is the highest (1.63 kg/m3), 80% treatment for AFI is the highest (2.05 kg/m3); in the same moisture treatment, AFI's water use efficiency is far greater than CFI, so it is a suitable water supply model for maize. |
