[0021] like Figures 1-5 As shown, a smart irrigation water and fertilizer mixing device includes a fertilizer storage tank 1, which has multiple independent fertilizer chambers 11 inside. Each independent fertilizer chamber 11 has a fertilizer inlet pipe 12 inside. A connecting block 13 is fixed above the fertilizer storage tank 1. The connecting block 13 has multiple connecting through holes 131 corresponding to the independent fertilizer chambers 11. One end of the fertilizer inlet pipe 12 is located at the bottom of the independent fertilizer chamber 11, and the other end is connected to a corresponding connecting through hole 131. A selection plate 14 is rotatably connected above the connecting block 13. The selection plate 14 has fertilizer suction holes 141. The fertilizer suction holes 141 can be connected to each connecting through hole 131 in sequence by rotation. A fertilizer suction hose 15 is connected to the fertilizer suction holes 141. The fertilizer suction hose 15 is connected to a fertilizer mixing pump 2. The selection plate 14 is driven to rotate by a driving device 3. Each independent fertilizer chamber 11 has a separate fertilizer inlet 111.

[0022] In this embodiment, each independent fertilizer chamber 11 stores different types of water-soluble fertilizer. When a specific type of fertilizer is needed, the drive device 3 drives the selection plate 14 to select the connecting through hole 131 connected to the fertilizer inlet pipe 12 in that independent fertilizer chamber 11, aligning the fertilizer suction hole 141 on the selection plate 14 with the connecting through hole 131. At this time, the fertilizer suction hose 15 on the fertilizer proportioning pump 2 is connected to the independent fertilizer chamber 11 through the fertilizer suction hole 141, and the fertilizer proportioning pump 2 can then draw fertilizer from the independent fertilizer chamber 11, proportion it, and output it to the crop. When fertilizer from other independent fertilizer chambers 11 needs to be selected, the selection plate 14 is rotated to align the fertilizer suction hole 141 with the connecting through hole 131 connected to the other independent fertilizer chamber 11.

[0023] The proportioning fertilizer pump 2 is further communicated with a liquid inlet pipe 21 and a fertilizer outlet pipe 22, the other ends of the liquid inlet pipe 21 and the fertilizer outlet pipe 22 are communicated with the water inlet main pipe 4, the water inlet main pipe 4 is communicated with a solenoid valve one 41 between the connecting ports of the liquid inlet pipe 21 and the fertilizer outlet pipe 22, and the liquid inlet pipe 21 and the fertilizer outlet pipe 22 are respectively communicated with a solenoid valve two 211 and a solenoid valve three 221.
