The utility model discloses an irrigator for long-distance laying and an embedded patch type drip irrigation tape of the irrigator. The irrigation emitter comprises a sheet-shaped body, a sawtooth-shaped flow channel and a water inlet channel are formed in the sheet-shaped body, a water inlet of the sawtooth-shaped flow channel is communicated with the water inlet channel, and a filtering structure for guiding water in a drip tube belt into the water inlet channel is arranged on one side face of the sheet-shaped body. The end part, far away from the water inlet, of the sawtooth-shaped runner is communicated with a water outlet cavity; the drip irrigation belt comprises an irrigation emitter for long-distance laying, the irrigation emitter for long-distance laying is installed on the innerside wall of the drip irrigation belt, and the side where the sawtooth-shaped flow channel is located makes contact with the drip irrigation belt; a drip irrigation opening for guiding water in the water outlet cavity into soil is formed in the side wall, where the water outlet cavity is located, of the drip irrigation belt. According to the scheme, the distance between the water drippers in the drip irrigation belt is fixed, and the hydraulic performance of the water drippers can be changed by changing the shapes of the flow channels in the water drippers, namely the sawtooth-shaped flow channels, so that the laying distance of the drip irrigation belt is increased.
