Abstract：Under different water head pressure and lasting time, makes tests inlaboratory and in greenhouse , measures the water flow rate each node of permeationirrigation pipeline, utilizes formulae to calculate uniformity of water flow accordingto single part tube and unit length mm separately. At the same time ,considers theinfluence of gluing factors .The result of the test shows that water flow ofpermeation irrigation pipe and time are not linear relations, the influence ofpressure water head to water flow is remarkable. However, its impact on the uniformityis not big, the uniformity of each point source water flow per meter of permeationirrigation pipeline is obviously higher than that of per joint of the pipeline, etc.
