摘要
本文简要介绍了地面灌溉田面水流运动、灌水质量评价指标及灌水新技术和设备方面国内外研究现状,分析了目前存在的问题、并探讨了地面灌溉未来的发展趋势;指出今后应把简捷易用的地面灌溉水流运动模拟软件开发,不同地区和土壤条件下田间入渗参数的取值及其地面灌溉合理灌水技术指标,不同地区阶式水平畦灌、膜孔膜侧灌、长畦分段灌等低成本地面灌溉技术的标准化灌水技术指标,适合国情的地面灌溉的实时反馈控制技术和设备、激光平地设备、波涌灌溉控制阀、闸管等的开发作为研究重点。
Study advance are briefly introduced,which include models of field surface water movement in present surface irrigation,quality index of irrigation water and new technique and equipment for irrigation. In addition, shortage in present research is analyzed and the trend of irrigation in the future is prospected. Emphasis of research in the future is pointed out, which include develop compact and convenient software for water movement in surface irrigation,confirming field infiltration coefficient with different region and soil, ration irrigation technique index of surface irrigation, and standardize irrigation technique index including stepped level border irrigation and nib irrigation which have low cost in different region, and developing timely feedback control technique,equipment for surface irrigation and laser flat equipment,wave irrigation,brake irrigation.
