山区自流灌区自压管道灌溉技术研

低压输水管道灌溉技术是一种有效的节水灌溉措施，具有节水、节能、省地、省工、输水便捷、适应性强等特点，目前在我国平原井灌区应用较为普遍。山区自流灌区发展管灌技术，尚有许多问题需要研究解决。结合红旗渠灌区节水灌溉技术研究，我们对山区自流灌区发展管灌技术进行了一些有益的探索，就此项研究中取得的成功经验和存在问题作一介绍，和大家共同探讨。

Research and Application of Pipe Irrigation Technique With Water Diversion by Gravity in Mountainous Irrigation District

The irrigation with low pressure pipeline is an effective water saving irrigation technique, with the characteristics of water and energy saving, occupying less land, using less labor, being easily operated and popularized, so it is widely used in plain region of well irrigation districts in China. However, some problems need to be studied and resolved in developing the irrigation technique with water diversion by gravity in mountainous region. In the paper, the successful practices and existing problems of the water saving irrigation technique are introduced with case study of the Hongqiqu Irrigation District, and some useful explorations on the development of pipe irrigation technique with water diversion by gravity in mountainous region are also conducted.
