Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1-3, an intelligent water, fertilizer, and medicine integrated irrigation system, comprising a water storage tank 1, a fertilizer liquid storage tank 2, and a medicine liquid storage tank 3, the bottom end of the water storage tank 1 is connected with a first water delivery pipe 4 and a second water delivery pipe 5, the end of the first water delivery pipe 4 away from the water storage tank 1 is sequentially connected with a first delivery pump 6, a first oscillating agitator 7, and a first differential mixer 8, the end of the second water delivery pipe 5 away from the water storage tank 1 is sequentially connected with a second delivery pump 9, a second oscillating agitator 10, and a second differential mixer 11, the fertilizer liquid storage tank 2 is fixedly connected to the top of the first water delivery pipe 4 and is located between the first delivery pump 6 and the first oscillating agitator 7, the bottom end of the fertilizer liquid storage tank 2 is connected with the first water delivery pipe 4 between the first delivery pump 6 and the first oscillating agitator 7 through the fertilizer delivery pipe, so that the fertilizer liquid is delivered to the first water delivery pipe 4 through the fertilizer delivery pipe, and then passes through the second water delivery pipe 5 in sequence. An oscillating stirrer 7 and a first differential mixer 8 make the water and the fertilizer liquid mix evenly. The fertilizer pipe is connected with a first electromagnetic control valve 12 and a first flow meter 13 in sequence, which can monitor and adjust the flow of the fertilizer liquid entering the first water pipe 4. The liquid medicine storage tank 3 is fixedly connected to the top of the second water pipe 5 and is located between the second delivery pump 9 and the second oscillating stirrer 10. The bottom end of the liquid medicine storage tank 3 is connected with the second water pipe 5 between the second delivery pump 9 and the second oscillating stirrer 10 through the drug delivery pipe, so that the drug liquid is transported to the second water pipe 5 through the drug delivery pipe, and then passes through the second oscillating stirrer 10 and the second differential mixer 11 in sequence to make the water and the drug liquid mix evenly. The drug delivery pipe is connected with a second electromagnetic control valve 14 and a second flow meter 15 in sequence, which can monitor and adjust the flow of the drug liquid entering the second water pipe 5.

[0021] In this embodiment, the first oscillating agitator 7 includes an oscillating tube 71, which is connected to the first water supply pipe 4. A plurality of annular protrusions 72 are arranged on the inner wall of the oscillating tube 71 at intervals along the length direction of the oscillating tube 71, so that the fertilizer liquid and water can be fully oscillated and mixed under the action of the annular protrusions 72 when passing through the oscillating tube 71.
