The present invention discloses a self-suction localized irrigation system, comprising a water supply container, a water inlet, at least one air inlet, a water outlet and a water pipe, wherein the water inlet, the air inlet and the water outlet are arranged on the water supply container; the water pipe is connected on the water outlet and is provided with at least one through hole; the water pipe is arranged on the surface of the earth; and a tubule water dropper which is arranged in soil is also included; one end part of the tubule water dropper is connected with the through hole; and the air inlet is higher than the water outlet. The self-suction localized irrigation system has the advantages of water and energy conservation, investment conservation, high irrigation uniformity and convenient use and management and the like; the depth of seeper can be adjusted and infiltration area is large in the process of infiltration, and the irrigation time is short, thus achieving the purpose of labor and time saving. In the present invention, uniform constant head pressure is obtained in all water guide devices by adjusting the height of the air inlet of an Ma bottle with scales, thereby improving irrigation uniformity and accurately controlling required irrigation quantity of water.
