| 摘 要： | 就影响间歇灌灌水质量的坡度、畦宽和单宽流量等技术参数进行分析和确定。在冬小麦试验地对间歇灌与连续灌进行了灌水试验,并对灌溉效率、节水率及均匀度进行了对比分析计算。结果表明,间歇灌与连续灌灌相比具有省水、节能、灌水均匀、效率高等优点。间歇灌比连续灌可节水15%以上,提高灌溉效率15%~24%,均匀度可达86%。

| Abstract: | Some technical parameters, such as the slope of farmland, the width of furrow, and the unit discharge, influencing the quality of intermittent border irrigation were analyzed and determined. Based on experiments on continuous irrigation and intermittent border irrigation in winter wheat fields, the irrigation efficiency, the water-saving ratio, and the unifomtity of different irrigation modes were compared. The result shows that intermittent border irrigation is characterized by water-savlng, energy-saving, high uniformtity and high efficiency. As compared with continuous irrigation, intermittent border irrigation can save water more than 15 % and improve irrigation efficiency by 15%-24%, and the uniformity of intermittent border irrigation can reach 86%. |
