    地下滴灌灌水器堵塞研究

    Clogging of emitter in subsurface drip irrigation system

      摘要
    • 摘要: 地下滴灌(SDI)是一种高效的节水灌溉技术，但系统易于堵塞，堵塞问题成为影响地下滴灌成败的关键。通过对运行8年的地下滴灌系统堵塞的实地调查，迷宫式、微管式和孔口式等3类型的灌水器均有不同程度的堵塞，堵塞率分别达到16.67%、25%和63.89%。分析3类型灌水器的堵塞状况，引起地下滴灌堵塞的主要原因是进入系统的微粒在流道壁的附着和发育。为此，提出加强过滤、定时冲洗和改变滴头流道设计等解决地下滴灌堵塞的建议。

       

      Abstract: Subsurface drip irrigation(SDI) is one of effective irrigation methods. But it is easy to clog. It is the key problem of the SDI system whether emitters are clogged. An investigation of emitter clogging was conducted in a SDI system, which had been running for 8 years. Clogging rates of Labyrinth emitter, mini-pipe and orifice reached 16.67%, 25% and 63.89%, respectively. These clogging were mainly caused by attached granule. Some sugestions were put forward was to solve this problem, such as enhancing filtration, flushing timely and improving the route of water in the emitter.
