The utility model discloses an intelligent adjustable irrigation gate valve based on soil characteristics. Main pipeline, the main pipeline is fixedly connected with a plurality of branch pipelines; outer side of main pipeline, a supporting frame is fixedly connected to the upper part of each branch pipeline in a sleeving manner; electromagnetic valves are fixedly connected to the upper side wallsof the sides, close to the branch pipelines, of the supporting frames; a partition plate is fixedly connected to the position, located at the lower end of the electromagnetic valve, in each branch pipeline. A cavity is formed in the partition plate; pull rods are fixedly connected to the lower ends of the electromagnetic valves; according to the utility model, the rotating sleeve is matched withthe extrusion block; the rotating sleeve is rotated to drive the extrusion block to move; the extrusion block extrudes the clamping ball to enable the clamping ball to be clamped with the groove in the branch pipeline; the irrigation device is convenient to assemble and disassemble, meanwhile, water passing of the branch pipelines is controlled through the electromagnetic valves, soil moisture isdetected in cooperation with the sensors, and therefore vegetation can be irrigated more scientifically and effectively according to soil characteristics.
