Self-adaptive water control system for rice planting field

The invention discloses a self-adaptive water control system for rice planting field. The system comprises a control water tank and a water conveying pipeline, a support is fixedly connected to the lower end of the control water tank, a supporting plate is fixedly connected to the lower end of the support, a control panel is fixedly connected to one side of the control water tank, a water level sensor is arranged in the control water tank, the water level sensor is electrically connected with the control panel, and the side, close to the lower end, of the control water tank is fixedly connected with a self-adaptive water pipe. According to the self-adaptive water control system for the rice planting field, a main pipeline and a water guide pipe are arranged to rapidly supply water to the rice planting field, water supply is stopped after the set water level is reached, a floating plate abuts against a slave water pipe so that the slave water pipe can be prevented from supplying water to the rice planting fiel
