The utility model relates to a spray drip pipe capable of interrupting fixed-point water supply, comprising: a pipe body including an upper half pipe body portion and a lower half pipe body portion defining a pipe space with the upper half pipe body portion, an upper half pipe body portion and a lower half pipe body portion. The lower half pipe body part is provided with a water spray hole adjacent to the first connection face； and the first baffle plate is adjacent to the first half pipe body part from the upper half pipe body part； One side of the engaging surface extends outward, defines a first open space with the lower half pipe body portion, and has a first plate body and a first flow guiding unit disposed on the first plate body. When the pipe space is filled with water, the water will be sprayed from the water spray holes, the first plate will block the water spray from the water spray holes, and the water will flow along the first plate, and then the first diversion unit will intercept the water , And guide the water to drip into the soil at a fixed point.一種可斷流定點供水的噴滴水管，包含：管體，包括上半管體部及和上半管體部界定管道空間的下半管體部，上半管體部及下半管體部銜接於相間隔的第一銜接面及第二銜接面，下半管體部在其鄰近所述第一銜接面處設有噴水孔；及第一擋板，自上半管體部鄰近第一銜接面的一側向外延伸，並和下半管體部界定第一開放空間，且具有第一板體及設置於第一板體的第一導流單元。當管道空間內填充水液時，水液會從噴水孔噴出，第一板體阻擋從噴水孔噴出的水液，且水液沿著第一板體流動，繼而第一導流單元截斷水液，並引導水液定點滴落至土壤中。
