Water and fertilizer integrated citrus cultivation system based on Internet of Things

The invention discloses a water and fertilizer integrated citrus cultivation system based on the Internet of Things, and belongs to the technical field of water and fertilizer integration. When water moves to the position of a dropper, a balloon generates buoyancy under the action of the water to drive a turning plate to rotate anticlockwise, a rubber plug blocks a valve ring, water in a pipeline cannot be discharged outwards through a dripping hole any more, and water in the pipeline cannot be discharged outwards through the dripping hole any more; when all the valve rings are blocked, the pressure in the pipeline is increased, the elastic piece is pressed to sink and drives the valve plug to move downwards under the action of the valve rod, air in the balloon can be exhausted into the branch air pipe through the connecting pipe and the exhaust pipe and is exhausted, and after the air in the balloon is exhausted, the turning plate rotates clockwise under the action of gravity to enable the valve rings to be
