In this embodiment, the water delivery and drainage system 1 comprises an irrigation main pipe 11, a connecting pipe control valve 12, an irrigation branch pipe 13, and a water meter 14 and a flexible joint 15 arranged upstream of the irrigation main pipe, wherein one end of the irrigation branch pipe 13 is communicated with the irrigation main pipe 11, and the other end is used for being connected to the drip irrigation small unit system 2. Wherein the connection pipe control valve 12 is provided on the irrigation branch pipe 13. Wherein the water meter 14 is connected with the flexible joint 15.

Namely, as shown in fig. 1 to 2, the present embodiment adds the irrigation branch pipe 13 based on the existing irrigation main pipe 11, so that irrigation water is conveyed to the irrigation branch pipe 13 from the irrigation main pipe 11 and then conveyed to the drip irrigation small cell system 2 by the irrigation branch pipe 13 to realize irrigation of plant roots, and at this time, the connection pipe control valve 12 is arranged on the irrigation branch pipe 13 to realize control of irrigation water.

In this embodiment, as shown in fig. 3, the drip irrigation cell system 2 includes a capillary tube 21 and a water outlet hole 22 opened toward the root of the plant. Wherein the capillaries 21 communicate with the irrigation manifold 13 such that irrigation water flows from the irrigation manifold 13 to the capillaries. The capillary tube 21 is provided with a water outlet hole 22 facing the plant root, and a quartz sand reverse filtering layer for preventing soil at the plant root from being washed is arranged on the water outlet hole 22 so as to prevent irrigation water flowing from the water outlet hole 22 to the plant root from washing the soil at the plant root; the spacing of the water outlet holes 22 is set corresponding to the plant planting density to ensure the irrigation efficiency of the plants, and in a specific embodiment, the plant planting density is 4 plants per square meter, that is, each plant occupies 0.25 meter, and the spacing of the water outlet holes is 0.25 meter.

Thus, as shown in fig. 1 to 3, when the irrigation water passing through the irrigation main pipe 11 is to be transmitted to the capillary 21, the connection pipe control valve 12 is opened, the irrigation water flows to the water outlet hole 22 on the capillary 21 through the irrigation branch pipe 13, so that the irrigation water is discharged to the root of the plant through the water outlet hole 22, and when the irrigation water passing through the irrigation main pipe is not to be transmitted to the capillary 21, the connection pipe control valve 12 is closed. Therefore, the drip irrigation technology can effectively avoid the evaporation of the flood irrigation water and the loss of the water along the way, and improve the utilization rate of water resources.

In this embodiment, the capillary 21 is a PVC (Polyvinyl chloride resin, polyvinyl chloride) plastic tube, and in other embodiments other suitable plastic tubes may be used. That is, the capillary tube 21 in this embodiment is formed by using a PVC plastic tube as a base material and forming a water outlet hole at 45 degrees downward from the center of the PVC plastic tube.

In this embodiment, as shown in fig. 4, the fertilization system 3 includes a backflow preventer 31, a fertilization valve 32, a fertilization connection pipe 33, and a fertilization tank 34.

Wherein, the backflow preventer 31 is connected with the water meter 14 through the flexible joint 15 to realize the connection of the water delivery and drainage system 1 and the fertilization system 3. The check valve is changed into a backflow preventer, so that the fertilizing water is prevented from flowing back into an upstream pipeline after the valve is prevented from polluting upstream water.

Wherein, the fertilization valve 32 is disposed at the downstream of the irrigation main pipe 11, the irrigation main pipe 11 is respectively communicated with one end of a fertilization connecting pipe 33 at the upstream and downstream of the fertilization valve 32, and the other ends of the two fertilization connecting pipes 33 are communicated with the fertilization tank 34.

In the present embodiment, when plants are to be fertilized, by controlling the fertilizer valve 32, fertilizer in the fertilizer tank 34 is delivered to the irrigation main 11 through the fertilizer connection pipe 33, and further delivered from the irrigation main 11 to the capillary 21 to the roots of the plants. Thereby fertilizer is applied to vegetation while irrigation, and the functions of pesticide spraying and pest removal can be added. Furthermore, quantitative fertilization is performed by controlling the fertilization valve 32, so that excess fertility can be avoided and pollution of agricultural tail water can be reduced.
