Abstract Under a certain pressure water head of lasting time, make a test in laboratory and in greenhouse,measures the water flow volume each node of permeation irrigation pipeline, utilizes the formulae to calculateuniformity of water flow according to single node. At the same time , considers the influence of gluing factors.The result of the test shows that water flow of permeation irrigation pipe with drilled holes is less than that ofcommon node permeation irrigation pipe, the uniformity of water flow from laboratory and greenhouse is nothigh , water flow of permeation irrigation pipe and time are not linear relations. and after bonding outerpermeation irrigation pipe with inner capillary tube, water flow is stable . Based the laboratory test, the wholewater head loss is very small of the capillary tube, and of whole tube, that is not big.
