| 摘 要： | 用土槽模拟试验的方法,对渗灌灌水时供水压力与节点渗灌管出水孔的水压关系进行了试验研究,结果表明:水源供水压力越大,水头损失越大,水头对渗灌管出水均匀效果产生影响,节点式渗灌灌水时供水压力以100cm水柱左右为宜.

| Abstract: | The relation between water supply pressure and outlet pressure of node permeation irrigation pipe is studied through the soil bin simulation test.The results indicates that bigger is the water supply pressure of water source,bigger is the head loss,and the water head has an affect on uniformity coefficient of output of node permeation irrigation pipe.The appropriate water supply pressure is 100cm water column for node permeation irrigation. |

| Keywords: | node permeation irrigation water supply pressure head loss |
