针对当前大面积推广节水灌溉的急需和农村经济条件的现实，采用塑料软管输水到畦中间，将长畦分段灌水，作为实施短畦灌溉的手段，即把管道节水与畦灌节水融为一体，通过测试分析，提出了不同土质的合理畦长的塑料软管的经济直径。经应用证明，提高灌溉有效利用系数４４％。且费用低、效果好，易为农民接受。

On Measurement Analysis of the Field Water-Saving Technology in the Jinxiang County

According to demand of spreading water-saving irrigation in large area and rural economic condition,the plastic hose is used for transfer water to the middle of a basin and separating a basin into several parts to practice short basin irrigation. This is a combination of pipe water transfer and basin irrigation water-saving. The economic diameters of plastic hose in a reasonable basin length for different soil textures have been presented through measurement analysis. The practice has proved that the water efficiency can be increased by 44%. The method has the advantages of lower cost and better effect and easy accepted by farmers.
