[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-4 As shown, an irrigation device for differential irrigation of a test plot comprises:

[0026] The water pipeline 1 has two groups of symmetrically distributed drainage pipes 101 connected to its surface;

[0027] The regulating component 2 is arranged inside the water pipeline 1;

[0028] The nozzle assembly 3 is arranged on the surface of the drainage pipe 101;

[0029] The regulating assembly 2 includes a plurality of regulating tubes 201 slidably connected to the inner wall of the water supply pipe 1 . Two symmetrically distributed regulating holes 202 are opened on the surface of the regulating tube 201 . The regulating holes 202 are connected to the adjacent drainage pipe 101 .

[0030] Attachment Figure 1 The arrows shown in the figure represent the direction of water flow. Water is discharged through the water supply pipe 1 and the drainage pipe 101 to be used for irrigation of the farmland in the experimental area.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, the opening of the regulating hole 202 is gradually reduced directly along the water flow conveying direction.

[0032] A sealing plate 205 is fixedly connected to the top of the regulating tube 201, and the sealing plate 205 is slidingly connected to the inner wall of the regulating tube 201. A threaded rod 204 is fixedly connected to the top of the sealing plate 205, and the upper end of the threaded rod 204 passes through the water supply pipe 1 and is provided with a nut 206.

[0033] Two resistance-increasing blocks 203 are fixedly connected to the top of the water pipeline 1 and are symmetrically distributed around the threaded rod 204 . The resistance-increasing blocks 203 are made of rubber material.

[0034] By rotating the nut 206 to separate it from the resistance increasing block 203, the limit on the threaded rod 204 can be released during this process, so that the threaded rod 204 can be pulled to slide between the two resistance increasing blocks 203 to achieve the effect of adjusting the position of the regulating tube 201. In this process, the change in the cross-section of the adjusting hole 202 can change the water flow rate of the water inside the water supply pipe 1 into the drainage pipe 101. After the adjustment is completed, the nut 206 is rotated in the opposite direction to make it fully contact with the resistance increasing block 203, so as to achieve the effect of limiting the position of the threaded rod 204 by utilizing the friction between the resistance increasing block 203 and the nut 206, so that the effect of differential irrigation can be achieved by changing the water flow rate of different drainage pipes 101.

[0035] like Figure 1 、 Figure 2 and Figure 4 As shown, the nozzle assembly 3 includes a sleeve 301 rotatably connected to the surface of the drainage pipe 101 , and the surface of the sleeve 301 is provided with uniformly distributed spray holes 307 .

[0036] A partition 305 is fixedly connected to the inner wall of the drainage pipe 101 , and an adjustment groove 306 corresponding to the spray hole 307 is opened on the surface of the partition 305 .

[0037] The surface of the drainage pipe 101 is provided with an annularly distributed threaded holes 304, the surface of the sleeve 301 is provided with a through hole 302, and the surface of the sleeve 301 is provided with a limiting screw 303, the other end of the limiting screw 303 passes through the through hole 302 and is threadedly connected to the inner wall of the adjacent threaded hole 304.

[0038] By removing the limiting screw 303, the sleeve 301 can be rotated to adjust the connection area between the spray hole 307 and the adjustment groove 306, thereby changing the drainage volume of the single drainage pipe 101, and further achieving the effect of differential irrigation of different experimental plots of farmland. The operation is simple. Compared with the traditional method of requiring separate pipe connections, this method can reduce the laying of pipes. It is only necessary to install the corresponding adjustment component 2, drainage pipe 101 and nozzle assembly 3 according to the experimental plot of farmland to achieve the adjustment of differential irrigation.

[0039] When the utility model is in use, water is discharged through the drainage pipe 101 via the water supply pipe 1 and is used for irrigation of farmland in the test area. Under the action of the regulating component 2 and the nozzle assembly 3, the laying of pipes can be reduced. It is only necessary to install the corresponding regulating component 2, drainage pipe 101 and nozzle assembly 3 according to the test field to achieve the adjustment of differential irrigation.

[0040] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
