自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。本文结合日照市岚山区黄墩镇下大峪节水灌溉工程设计,对自流灌区的技术进行了探讨,并与渠道防渗灌溉技术进行比较,提出了自压管道输水技术在节水灌溉工程中的应用时应注意的问题。 Self-pressurized water pipeline irrigation technology is an effective water-saving irrigation measures, with the characteristics of water saving, energy saving, land saving, labor saving, water conveyance convenient, strong adaptability and so on. Currently, it is widely used in plain well irrigation areas in China. Based on the design of Xiaodaiyu water-saving irrigation project in Huangdun Town, Lanshan District, Rizhao City, this paper discusses the technology of gravity irrigation area and compares it with the technology of seepage control irrigation. Proposes the self-pressurized pipeline technology in water-saving irrigation project In the application should pay attention to the problem.
