摘　　要：滴灌灌水均匀度是滴灌系统设计及评价的一项重要的水力性能指标,以单翼迷宫式滴灌带为研究对象,采用物理试验与数值模拟的方法对滴灌带流道和灌水均匀度进行研究。结果表明,毛管铺设长度为20 m,工作压力高于40 kPa时对应的工况较优;提出滴灌带流道的设计应与流体主航道一致;得出迭代法构建的灌水均匀度与两因素的数学模型精度更高。研究成果可为田间大棚微地形下滴灌毛管的应用及滴灌系统设计提供参考。The uniformity of drip irrigation is an important hydraulic performance index for the design and evaluation of drip rrigation systems.Taking the single-wing labyrinth drip rrigation belt as the research object,the flow path and irrigation uniformity of the drip irrigation belt were studied by physical experiments and numerical simulation methods.The results show that the capillary laying length is 2Om,and the corresponding working condition is better when the working pressure is higher than 4okPa;it is proposed that the design of the drip irrigation belt flow channel should be consistent with the main channel of the fluid;The model is more accurate.The research results can provide reference value for the application of capillary drip irrigation and the design of drip irrigation system under the micro-topography of field greenhouses.
