And an overflow protection valve 15 is also arranged on the water distribution pipeline 3. In this embodiment, the arrangement of the overflow protection valve 15 can prevent the water and fertilizer in the stirring tank 2 from overflowing and causing unnecessary waste.

A first filter 16 is disposed on the side of the EC sensor 10 on the water distribution pipe 3 close to the fresh water tank 5. In the present embodiment, the first filter 16 is provided to filter the water source entering the agitation tank 2.

The automatic control system comprises a controller in signal connection with the fertilizing valve group 1, the metering valve 7, the water distribution pump 14, the EC sensor 10, the PH sensor 11, the feeding pump 12 and the flow meter 13, and the controller is in signal connection with a PC.

A second filter 17 is provided in the water supply pipe 2 at a position between the communication pipe 9 and the flow meter 13. In this embodiment, the second filter 17 is arranged to filter the liquid manure, so as to avoid blocking the fertilizing valve set 1 for the melted fertilizer and affecting the irrigation of plants.

The utility model is illustrated in detail by the following examples:

when the device is used, the running process is started by sending a signal by the PC, and the starting command is used for starting the preparation of water and fertilizer or an irrigation cycle. By means of the water distribution pump 14, the fresh water in the fresh water tank 5 flows towards the mixing tank 2, this water can be mixed with the waste water and filtered by means of the first filter 16, ensuring that the irrigation water used is pure to avoid diseases infecting the crops, before the water flows to the mixing tank 2, the EC sensor 10 can measure its EC level, which indicates the amount of nutrients already contained in the water, and the fertigation formula can be adjusted on the basis of the measured value. This can save fertilizer. The feed pump 12 sucks water from the mixing box 2 and through the venturi 8, as a result of which the fertilizer or other substances in the fertilizer box 6 are sucked in from other channels connected to the venturi 8, and the doses of the various substances are dosed by means of the dosing valve 7 according to the fertilizer formulation, each fertilizer or other substance being supplied via a separate fertilizer dosing pipe 4, the fertilizer dosing pipes 4 together forming a "dosing street", and by means of the arrangement of the venturi 8 a vortex is formed in the mixing box 2, which vortex can be used to mix and aerate water and fertilizer well.
