摘    要:小畦灌是我国北方一些灌区从灌溉实践中摸索出来的一种新型地面灌水技术。在对冬小麦田间灌水试验资料分析的基础上,建立了灌水定额与畦坡、单井出水量和畦宽的关系,并对灌水均匀度与单宽流量和畦长进行了相关分析。结果表明:在适当控制畦宽和畦长的情况下,可以减少深层渗漏、降低灌水定额、提高灌水均匀度和田间水利用率,从而实现节水、节能的目的。

关 键 词:小畦灌  灌水定额  均匀度  节水

Abstract:Border irrigation is a new kind of surface irrigation technique derived from the irrigation practice in the irrigation district in northern China. This article presents respectively the relations between irrigation quota and slope of farmland, the water yield of a single well, and width of the border. The results show that if the width and the length of the border are carefully designed, border irrigation can reduce deep percolation and irrigation quotas, and improve irrigation uniformity and efficiency of field water use. At same time, it can save water and energy.
Keywords:border irrigation  irrigation quota  uniformity  water saving
