| 摘 要： | 滴灌具有高效节水、省工节地、增加产量等优点。山地滴灌工程设计、灌溉参数的设计与压力控制是保证工程正常运行的关键,为了充分发挥滴灌工程效益,结合实际工程,对微灌工程的耗水强度、补水强度、土壤湿润比、灌水均匀度等参数做了计算,对管道布置、毛管长度、轮灌组做了设计并对支管入口压力与减压阀位置做了分析,得出了滴灌耗水强度和补水强度均为6mm·d-1,湿润带宽75cm,灌溉湿润比值48%,在计算水压为3~4kg范围内安放减压阀的结论,可为类似的工程设计提供参考。

| Abstract: | Drip irrigation has the virtue of water-saving, labor-saving, land-saving, and raising production. Irrigation parameters design and pressure control are the key to ensure the normal operation of mountain drip irrigation engineering. In order to give full play to the drip irrigation engineering benefit, combining with the actual project, the water consumption, water supplement, moist soil, irrigation uniformity parameters of microirrigation engineering were calculated, pipe layout, capillary length, rotational irrigation were designed, and the inlet pressure of branch pipe and the pressure reducing valve position were also analyzed. It is concluded that the drip irrigation water consumption intensity and water supplement intensity are all 6ram per day, moist bandwidth 75cm, humid irrigation ratio 48 %. The pressure reducing valve is set with water pressure ranging from 3 to 4kg. The findings can provide a reference for similar engineering design. |
