Because different plants require different soil, sometimes all the plant planting plots do not need to be irrigated simultaneously, the irrigation control end only sends a valve opening signal to the irrigation valve 111 corresponding to the plant planting plot needing irrigation, and only the plant planting plot needing irrigation can be irrigated. Because different plants have differences to the types and the demand of fertilizers, the types of fertilizers to be applied to different plant planting plots during irrigation are different, the irrigation system of the embodiment can flexibly adjust the types of fertilizers absorbed by the fertilization pipeline according to actual irrigation requirements, for example, some plant planting plots need to be applied with fertilizer A and fertilizer B, some plant planting plots need to be applied with fertilizer A and fertilizer C, and by applying the irrigation system of the embodiment, when the plant planting plots needing to be applied with fertilizer A and fertilizer B are irrigated, a worker can send a control signal to the flow regulating valve 28 corresponding to the fertilizer liquid storage device 27 where other fertilizers except fertilizer A and fertilizer B are located through the irrigation control end, so that the flow regulating valve 28 regulates the flow to 0, namely, the liquid outlets of the fertilizer liquid storage devices 27 where other fertilizers except fertilizer A and fertilizer B are located are closed, so that only fertilizer A and fertilizer B are absorbed into the main water supply pipeline 100, and only fertilizer A and fertilizer B are applied during irrigation. When the plant planting plot needing to be applied with the fertilizer A and the fertilizer C is irrigated, a worker can send a control signal to the flow regulating valve 28 corresponding to the fertilizer liquid storage device 27 where the other fertilizers except the fertilizer A and the fertilizer C are located through the irrigation control end, so that the flow regulating valve 28 regulates the flow to 0, namely, the liquid outlets of the fertilizer liquid storage devices 27 of the other fertilizers except the fertilizer A and the fertilizer C are closed, only the fertilizer A and the fertilizer C are sucked into the main water supply pipeline 100, and only the fertilizer A and the fertilizer C are applied during irrigation.
The above description is only an embodiment of the present invention, and the scope of protection is not limited thereto. The invention is not limited to the above embodiments, but may be modified within the scope of the appended claims.
