地表多水门管道畦灌试验研究

A Study on Gated Pipe System for Basin Irrigation

多水门管道灌溉是采用多水口管道替代水沟的一种地表灌溉方式。１９９３至１９９５年试验结果表明，多水门管道灌溉和传统水沟灌溉相比，具有节水、节能、改善灌水分布均匀度，提高灌溉质量。

Gated pipe irrigation is a type of surface irrigation in which the conventional main ditch and field lateral ditch are replaced by above ground pipeline and gated pipe.Irrigation water flows from gates which are regularly spaced along the pipeline.The experiment results from 1993 to 1995 indicate that the gated pipe system for basin irrigation can save water and energy,improve the irrigation distrbution uniformity and help extend cropping land.It is considered as an irrigation alternative where the ditches are previously used,and has great potential to be widely extented in the well irrigation region of Hebei Plain and northern China.
