| 摘 要： | 覆膜灌溉是在覆膜种植基础上进行灌溉的一种新型地面灌溉技术，具有显著的节水、增产效果。由于地膜覆盖对田面水流运动规律有着显著的影响，所以为了提高灌水均匀度和灌水效率，需要对覆膜灌溉的灌水技术参数进行专门研究。该文结合对灌溉地表水流运动的数值模拟，以灌水均匀度最高为目标函数，考虑灌水定额、田面水深、单宽流量、地膜开孔率等约束条件，建立了覆膜灌溉的灌水技术要素优化模型，并利用在新疆乌兰乌苏棉花田所进行的试验结果，通过计算得到了覆膜灌溉的最优灌水技术方案。

| Abstract: | Irrigation with plastic mulch is a new kind of surface irrigation method, it has both water-saving and yield-increasing effect. Plastic mulch affects motion laws of surface flow remarkably. So that it is requirement that study on irrigation technique for the irrigation with plastic mulch to increase irrigation uniformity and irrigation efficiency. This paper develops optimal mathematics model for the irrigation technique of the irrigation with plastic mulch based on numerical simulating to the motion of surface flow. Objective function of the optimal model is the irrigation uniformity, constraint conditions meet limits in irrigation norm, water depth on field surface, inlet unit-width discharge, and rate of plastic film hole. The optimal irrigation technique schemes for the irrigation with plastic mulch with holes are determined via calculating using data from the cotton experimental field at Wulanwusu Agrometeorological Station, Xinjiang. |
