The invention discloses an intelligent sprinkler irrigation control system for a garden. The system comprises a pressure water supply device, an angle rotation locating device, a self-moving small irrigator, a soil humidity monitoring device and an electronic-controlled device. The intelligent sprinkler irrigation control system for the garden adopts a central control computer for centralized control, after comparison and judgement are conducted according to soil humidity data fed back by soil humidity sensors, translation and rotation and locating of a rotating platform of the angle rotation locating device are controlled according to garden coordinate information preset by a program and coordinate information of the soil humidity sensors to make the self-moving small irrrigator right opposite to the position needing to be irrigated, self-moving sprinkler irrigation is conducted, sprinkler irrigation can be conducted on garden vegetation conveniently, the use flexibility is high, maintenance is convenient, a water transportation pipe network does not need to be embedded in a garden sprinkler irrigation area, the problems such as spray head combination space do not need to be considered, the garden construction engineering quantity is reduced, by means of the self-moving sprinkler irrigation mode, on the premise of saving the water resource, uniform distribution of water in sprinkler irrigation soil is achieved, the system is especially suitable for garden sprinkler irrigation.
