摘要
利用渠道输水灌溉在我国具有悠久的历史 ,也是目前我国农田灌溉中的一种主要形式 ,渠灌区占现有农田灌溉总面积的 5 6 %。作为一种传统的灌溉方式 ,渠灌类型区普遍存在管理粗放 ,水资源浪费严重 ,灌溉水利用率低等问题。就节水灌溉潜力而言 ,渠灌类型区最大 ,任务也最艰巨。本文介绍了“渠灌类型区农业高效用水模式与产业化示范”
Trench irrigation system is a main irrigation form at present in China, and it also has a very long history. Trench irrigation area occupied 56% of total irrigation area. As a kind of traditional irrigation system, trench irrigation has many problems such as slack management, the serious waste of water resource and the lower water use efficiency. Trench irrigation has the highest potential of saving water, and the mission is also the hardest. This paper introduces the phase achievements and the project progress on the mode and industrialization demonstration for high efficient use of agricultural water in trench irrigation system.
