It not only leads to the degradation of land resources, but also has a profound impact on the ecological environment and human society. The soil in desertified areas is poor, water is scarce, and vegetation is difficult to grow, which further exacerbates the expansion of the desert. Traditional methods of sand prevention and control, such as afforestation and laying grass grids, have played a role in preventing wind and fixing sand to a certain extent, but there are problems such as low survival rate, high maintenance cost, and difficulty in construction.

[0023] like Figure 6 , Figure 7 As shown, the limiting structure is arranged on the inner wall of the docking hole 3 and is used to limit the implant tube 5 in the inner cavity of the main tube 1; like Figure 8-Figure 10 As shown, the pressing structure is arranged on one side of the main pipe 1 and is used to squeeze the implant tube 5 out of the inner cavity of the main pipe 1 .

[0024] Further, such as Figure 3 As shown, a plurality of butt joint plates 6 are fixedly connected to the bottom of the outer wall of the main pipe 1, and the plurality of butt joint plates 6 are fixedly connected to the top of the butt joint piece 2 by first butt joint bolts 7. When performing maintenance, the main pipe 1 and the butt joint piece 2 can be quickly separated by simply removing the first butt joint bolts 7, thereby improving disassembly efficiency; Further, such as Figure 4 As shown, a slot 28 is provided at the bottom of one side of the docking piece 2, and a plug 29 corresponding to the slot 28 is provided on one side of the whole floor 4. The plug 29 is inserted into the corresponding slot 28 and is fixedly connected to the docking piece 2 by a second docking bolt 30. When performing repair and maintenance, it is only necessary to remove the second docking bolt 30 to quickly separate the whole floor 4 from the docking piece 2, thereby improving the disassembly efficiency. When planting, the staff can level the soil through the whole floor 4 without carrying additional leveling tools. After leveling, the bottom of the whole floor 4 is fitted with the leveled ground, and the top of the whole floor 4 is stepped on to avoid shaking of the main pipe 1 and the docking piece 2 during planting, thereby improving the stability during planting.

[0025] Further, such as Figure 6 and Figure 7 As shown, two first avoidance grooves 12 are symmetrically provided on the inner wall of the docking hole 3, and a limiting structure is provided in each of the two first avoidance grooves 12. The limiting structure includes a support rod 13 and a torsion spring 14. A docking shaft 15 is rotatably connected in the first avoidance groove 12, and the support rod 13 is fixedly sleeved on the docking shaft 15. A torsion spring shaft 16 is installed on the side of the first avoidance groove 12 away from the docking shaft 15, and the torsion spring 14 is sleeved on the torsion spring shaft 16. One end of the torsion spring 14 abuts against the side wall of the first avoidance groove 12, and the other end abuts against the bottom of the support rod 13. Combination Figure 2 , Figure 5 and Figure 7 The two support rods 13 abut against the outer wall of the clamping section 9 of the planting pipe 5 at the bottom of the main pipe 1.

[0026] Further, such as Figure 1 , Figure 8 and Fig. 9 As shown, the pressing structure includes a hand grip rod 17 and a force transmission rod 18, a limit block 19 is arranged on one side of the main pipe 1, a limit slot 20 is arranged on the limit block 19, one end of the hand grip rod 17 is slidably connected in the limit slot 20, the force transmission rod 18 is slidably connected to the limit block 19, and the top end of the force transmission rod 18 passes through the limit block 19 and is fixedly connected to the hand grip rod 17, a compression spring 21 is fixedly connected to the bottom of the limit block 19, a connecting ring 22 is fixedly connected to the rod body of the force transmission rod 18, and the bottom end of the compression spring 21 is fixedly connected to the connecting ring 22.

[0027] Furthermore, an auxiliary grip 27 is fixedly connected to one side of the main pipe 1 away from the hand grip 17, and the interiors of the force transmission rod 18 and the auxiliary grip 27 are hollow, thereby reducing the overall weight.

[0028] Further, combined with Figure 2 , Figure 3 , Figure 8 and Fig.10 A push groove 23 is provided at one end of the main pipe 1 close to the docking piece 2, and a second avoidance groove 24 connected to the push groove 23 is provided on one side of the docking piece 2. A pressing plate 25 is slidably connected to the bottom end of the force transmission rod 18, and one end of the pressing plate 25 slides through the push groove 23, and the bottom of the pressing plate 25 abuts against the upper surface of the limit edge 11 of the planting pipe 5 at the bottom of the main pipe 1. The second avoidance groove 24 can prevent the pressing plate 25 from interfering with the docking piece 2 when moving downward.

[0029] Specifically: when planting, the worker first levels the soil through the floor 4, and after leveling, the bottom of the floor 4 is fitted with the leveled ground, and the top of the floor 4 is stepped on, and then one hand holds the auxiliary grip 27, and the other hand holds the hand grip 17 and pushes the hand grip 17 downward, and the hand grip 17 slides downward along the limit slide groove 20, and at the same time, the hand grip 17 drives the pressing plate 25 to move through the force transmission rod 18, so that the pressing plate 25 slides downward along the push groove 23, and the pressing plate 25 moves downward along the limit slide groove 11. The planting tube 5 is squeezed out from the main pipe 1. During the extrusion process, the piercing section 10 of the planting tube 5 will first penetrate into the soil. As the pressing plate 25 is pressed downward, the limiting edge 11 on the planting tube 5 will pass through the docking hole 3. At this time, since the piercing section 10 penetrates into the soil, the limiting edge 11 is located above and below the soil and no longer moves toward the middle and lower part. The soil will limit the piercing section 10 to prevent the planting tube 5 from shaking. As the pressing plate 25 is pressed downward, the portion below the limiting edge 11 of the planting tube 5 is pressed into the soil. When the force transmission rod 18 moves downward, the compression spring 21 is stretched. After the implantation is completed, the hand grip rod 17 is pulled upward to reset the hand grip rod 17, the force transmission rod 18 and the pressing plate 25. During the pulling process, the compression spring 21 in the stretched state will shrink and reset, thereby assisting the force transmission rod 18 to reset through the connecting ring 22. During the extrusion process of the planting tube 5, the outer wall of the clamping section 9 and the limiting edge 11 will squeeze the support rod 13, causing the support rod 13 to rotate into the first avoidance groove 12, so that the planting tube 5 can be moved out of the docking hole 3. During the rotation process, the support rod 13 will squeeze the torsion spring 14, and the torsion spring 14 is in a compressed state. When the planting tube 5 is completely moved out of the docking hole 3, the torsion spring 14 in the compressed state will reset and push the corresponding support rod 13 to reset.

[0030] Example 2 like Figure 1-Figure 11 As shown, this embodiment is improved as follows on the basis of embodiment 1: Further, as shown in FIG. Figure 3 , Fig.10 As shown, a displacement groove 26 is provided on the pressure plate 25, and the bottom end of the force transmission rod 18 is slidably connected to the displacement groove 26. Specifically: after the pressure plate 25 is reset, the pressure plate 25 is pulled outward. At this time, the plate body of the pressure plate 25 located in the main pipe 1 will move into the push groove 23. At this time, the planting tube 5 above the pressure plate 25 will slide downward, and the support rod 13 will abut against the outer wall of the clamping section 9 of the bottom planting tube 5 to prevent the planting tube 5 from sliding out of the docking hole 3. After the support rod 13 abuts against the outer wall of the clamping section 9, the pressure plate 25 is pushed inward to reset it.

[0031] Further, such as Figure 1 As shown, transparent windows 31 corresponding to the plurality of limit edges 11 are provided on the pipe wall of the main pipe 1 , so that the staff can intuitively understand the number of the planting pipes 5 in the main pipe 1 .

[0032] In summary, the workflow of the present invention is: When planting seed sand barriers, the staff first levels the soil through the leveling floor 4, and after leveling, fits the bottom of the leveling floor 4 with the leveled ground, and steps on the top of the leveling floor 4, then holds the auxiliary grip 27 with one hand, and holds the hand grip 17 with the other hand and pushes the hand grip 17 downward, so that the pressing plate 25 slides downward along the push groove 23, and the pressing plate 25 presses the limiting edge 11 downward, thereby squeezing the planting tube 5 out of the main pipe 1. During the extrusion process, the piercing section 10 of the planting tube 5 will first penetrate into the soil, and as the pressing plate 25 is pressed downward, the limiting edge 11 on the planting tube 5 will pass through the docking hole 3. At this time, since the piercing section 10 penetrates into the soil, the soil will limit the piercing section 10 to prevent the planting tube 5 from shaking, and as the pressing plate 25 is pressed downward, the portion below the limiting edge 11 of the planting tube 5 is pressed into the soil; After the seed sand barrier planting is completed, the hand grip rod 17 is pulled upward to reset the hand grip rod 17, the force transmission rod 18 and the pressure plate 25. After the pressure plate 25 is reset, the pressure plate 25 is pulled outward. At this time, the pressure plate 25 located in the main pipe 1 will move into the push groove 23. At this time, the planting tube 5 above the pressure plate 25 will slide downward. At this time, the support rod 13 will abut against the outer wall of the clamping section 9 of the bottom planting tube 5, and then push the pressure plate 25 inward to reset it for the next planting.

[0053] Table 1 Experimental seedling observation record

[0054] As can be seen from Table 1, because Examples 3-5 adopt the technical solution of the present invention, the 21-day survival rate is as high as 97%, achieving very good technical effects.

[0055] Comparative Example 1 adopts the existing scheme. Due to the long wind and sand invasion, the sand depth outside the sand-proof vegetation block 32 is different, and the germination rate is also very low; on the other hand, the seedlings are attacked by wind and sand as soon as they germinate, resulting in a large number of deaths as soon as they germinate, which not only wastes a lot of manpower and water resources, but also the final survival rate is less than half.

[0056] In Comparative Example 2-4, the lack of seed initiator, water retaining agent and mineral humic acid in the matrix affected the germination of seeds and the final result was not very ideal.

[0057] Since comparative example 5 lacks attapulgite, its adhesion is affected when it is pressed into vegetation blocks. When it is connected to the sand barrier planting device, a large amount of breakage occurs, which eventually leads to the loss of nutrients and seeds, and the survival rate is seriously affected.

[0058] Comparative Examples 6-7 had good effects at the initial emergence. However, in subsequent experiments, it was observed that when the spacing was too small, the growth space of the seedlings was affected and the growth was weak; when the spacing was too large, the invasion of quicksand could not be effectively prevented.
