An infiltration irrigation apparatus, comprising: a water passage chamber (1) having a water outlet (12) and a water inlet (11), in which a stream of water is formed along an axial direction of the water passage chamber (1) when water flows between the water inlet (11) and the water outlet (12); one or more porous filter membranes (2) disposed in the water passage chamber (1) and formed with a filtration section (20) to house the water filtered by the one or more porous filter membranes (2), in wherein the location location of the one or more porous filter membranes (2) is adjusted so that at least a portion of the water stream flows along a surface of the porous filter membrane (2) to wash the surface when the axial water flow exists in the water passage chamber (1); and one or more flow reducers (3), each arranged in a side wall of the water passage chamber (1) corresponding to the porous filter membrane (2), in which each of the one or more water reducers flow (3) has one or more restriction holes, an inlet communicated with the filtration section (20) of the one or more porous filter membranes (2) and an outlet outside the water passage chamber (1), a maximum pore diameter of the restriction hole being greater than that of the porous filter membrane (2), and a total water filtration capacity of the one or more flow reducers (3) being smaller than that of the one or more porous filter membranes (2).Un aparato de irrigación por infiltración, que comprende: una cámara de paso de agua (1) que tiene una salida de agua (12) y una entrada de agua (11), en el que se forma una corriente de agua a lo largo de una dirección axial de la cámara de paso de agua (1) cuando el agua fluye entre la entrada de agua (11) y la salida de agua (12); una o más membranas de filtro porosas (2) dispuestas en la cámara de paso de agua (1) y formadas con una sección de filtración (20) para alojar el agua filtrada por la una o más membranas de filtro porosas (2), en el que la ubicación local
