[0029] Combination Figure 7 , Fig.11 and Fig.12 , 13 As shown, there are multiple annular seepage main pipes 5, which are evenly distributed in the vertical direction. The annular seepage main pipes 5 include multiple arc-shaped seepage water branches 51, and the seepage holes 52 are arranged at the lower ends of the arc-shaped seepage water branches 51. The water inlet pipe 4 is provided with a water outlet 41 for connecting with the arc-shaped seepage water branches 51, and the water inlet pipe 4 is provided with a water inlet 42 for connecting with the drain pipe 316 near its upper end.

[0030] In addition, the inner side of the water body 31 close to the tree trunk 1 is made of soft material, the outer side away from the tree trunk 1 is made of hard material, and the side of the water body 31 facing outward is made of transparent material; the water body 31 contains water, and there are also multiple plastic parts suspended in the water in the water body 31, the plastic parts are in the shape of fish, and the side of the water body 31 facing outward is provided with water plants and stone patterns.

[0031] When the present application is used, a large tree soil ball 11 is placed in the planting hole. After it is stabilized, three lower support sleeves 62 are evenly distributed around the soil ball 11 and inserted into the deeper soil at the bottom of the tree hole. The tapered portion 623 of the lower support sleeve 62 makes it easier to insert into the soil. Then the upper support sleeve 61 is installed on the upper end of the lower support sleeve 62. Then the arc-shaped seepage branch 51 is connected with the water inlet pipe 4 on the upper support sleeve 61, and the three arc-shaped seepage branch 51 are connected to form an annular seepage main pipe 5, wherein the seepage holes 52 on the annular seepage main pipe 5 face downward, and the soil is backfilled in the planting hole, the surface is basically level with the ground 12, and the upper end of the upper support sleeve 61 and the upper end of the water inlet pipe 4 are slightly higher than the ground 12.

[0032] Then, three water bodies 31 are placed around the tree trunk, and then the lower end of the support rod 10 is passed through the annular limit portion 314, the guide channel 313, the connecting sleeve 621 in turn and finally abutted against the upper end of the tapered portion 622, the screw cover 315 is tightened, the positioning column 8 is installed on the outside of the screw cover 315, and the two adjacent positioning columns 8 are connected by the second connecting rod 9, and then the fixing plate is surrounded to form a fixing ring 2 with an annular structure and wrap the trunk 1, and the positioning column 8 and the first ear plate 21 on the fixing ring 2 are connected by the first connecting rod 7.

After the device is installed, the part of the water inlet pipe 4 extending out of the ground 12 is a transparent part, which is made of transparent material. When the irrigation device is constantly injecting water, the red plastic stick cannot float to the transparent part due to the water pressure. When the water in the soil increases due to the injection of water, so that the water seepage hole 52 no longer seeps water, the red plastic stick will float to the transparent part, and the faucet can be closed at this time to stop injecting water. Therefore, it can be judged whether the faucet needs to be closed by the red plastic stick.

[0034] If watering is not needed, the fixed structure, water container 3 and support rod 10 can be removed, and the water inlet pipe 4 buried in the soil and the support rod 6 can be retained. At this time, the water inlet on the water inlet pipe 4 is located above the ground. When watering is not needed, it can be used for ventilation of the roots of large trees.

When watering, the water in the irrigation device 3 enters the annular seepage main pipe 5 after passing through the drainage pipe 316 and the water inlet pipe 4, and then seeps out through the seepage hole 52, which not only saves water, but also directly transports water to the vicinity of the root system, making it easier for the trees to absorb water, thereby effectively fixing the transplanted trees, preventing them from falling over due to wind, and watering, which is beneficial to the growth of trees and improving the survival rate of trees.
