Mobile horticultural irrigation system

The invention discloses a mobile horticultural irrigation system. The mobile horticultural irrigation system comprises a moving unit, a water tank and a sprinkling unit, wherein the water tank is rotatably arranged at the top of the moving unit; the sprinkling unit comprises a mechanical arm and a sprinkling machine; and the lower end of the mechanical arm is connected with the water tank, and theupper end of the mechanical arm is connected with the sprinkling machine. According to the mobile horticultural irrigation system disclosed by the invention, the water tank is driven to rotate through a steering engine, so that the mechanical arm is driven to synchronously rotate, and the situation that a pipeline between the water tank and the mechanical arm is blocked caused by twisting is avoided; and the sprinkling machine utilizes the interaction between a liquid drop spray nozzle and an air flow spray nozzle, so that under the premise that the volume weight of a pump body is controlled,the effective coverage ar
