Description

Technical Field

[0001] The present invention belongs to the field of planting with anti - sand vegetation blocks, and particularly relates to a maintenance - free and highly - viable matrix seed sand barrier, its use method and application. Background Art

[0002] Desertification is a serious environmental problem faced globally. 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 barren and water - scarce, making it difficult for vegetation to grow, which further exacerbates the expansion of deserts. Traditional anti - sand and desertification control methods, such as tree planting and laying straw checkerboards, although playing a role in wind prevention and sand fixation to a certain extent, have problems such as low survival rate, high maintenance cost, and great construction difficulty.

[0003] In order to improve the effect of anti - sand and desertification control and reduce the maintenance cost, in recent years, scientific research personnel have continuously explored new anti - sand and desertification control technologies. Among them, the seed sand barrier, as an innovative anti - sand method, has gradually attracted people's attention. The seed sand barrier fixes drifting sand by pre - setting vegetation blocks containing seeds on the sandy land and utilizing the growth ability of the seeds to achieve the purpose of anti - sand and desertification control. However, there are still some problems in the actual application of existing seed sand barriers, such as low seed survival rate.

[0004] On the other hand, in the existing technology, when planting vegetation blocks, workers need to use leveling tools to level the uneven sandy soil area, then use shovels to bury the vegetation blocks into the sand, and then water the large - area land, wasting a lot of manpower and material resources. Summary of the Invention

[0005] In view of the above problems, the present invention proposes a maintenance - free and highly - viable matrix seed sand barrier, aiming to improve the seed survival rate and the effect of anti - sand and desertification control by optimizing the composition, arrangement mode of the vegetation block and the construction device, as follows:

[0029] On the other hand, the present invention provides an application of a maintenance-free high-survival matrix seed sand barrier, which is characterized in that it is used for sand prevention and control in the desert.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. The seed sand barrier adopted by the present invention uses a specific sand-preventing and vegetation-growing block, which is composed of various drought-tolerant and sand-embedding-tolerant plant seeds and an optimized substrate. It can ensure that the seeds grow rapidly and fix the shifting sand in the harsh desert environment. At the same time, the vegetation-growing blocks are arranged in a matrix, and through reasonable settings of the horizontal and vertical spacings, it can not only ensure the growth space of the seeds but also effectively prevent the invasion of the shifting sand.

[0032] 2. The present invention also provides a sand barrier planting device for planting the seed sand barrier. When in use, the staff can level the soil through the leveling plate without carrying additional leveling tools. After leveling, the bottom of the leveling plate is attached to the leveled ground, and the top of the leveling plate is stepped on to prevent the main pipe and the docking part from shaking during planting. At the same time, when planting, by stepping on the top of the leveling plate, the shaking of the main pipe and the docking part during planting can be avoided, improving the stability during planting. Under the action of the pressing structure, the staff only needs to press down the handgrip rod to plant the planting pipe into the soil through the pressing plate, which is convenient and fast. A plurality of planting pipes in the main pipe are stacked in a head-to-tail plug-in form, thereby increasing the storage capacity of the main pipe for the planting pipes.

[0033] 3. The present invention also provides a sand barrier planting device. When performing maintenance, by removing the first docking bolt, the main pipe and the docking part can be quickly separated; by removing the second docking bolt, the leveling plate and the docking part can be quickly separated, improving the disassembly efficiency.

[0034] 4. After the planting of the sand barrier planting device in the present invention is completed, the limiting edge of the planting pipe is inserted into the sand below, and the part above the limiting edge is arranged above the sandy soil; the part above the limiting edge can reduce the influence of wind erosion on the soil structure of the sand-preventing and vegetation-growing block, thereby reducing the loss of nutrients and improving the survival rate of the seeds. At the same time, when the seedlings grow out, it can also protect the seedlings, further improving the survival rate of the seedlings. At the same time, during the insertion process of the insertion section, the original sandy soil in the sandy soil will flow into the inner cavity of the insertion section. During the germination process of the seeds, the roots of the seeds penetrate through the soil of the sand-preventing and vegetation-growing block and extend into the original sandy soil, thereby fixing the original sandy soil. When the humidity outside the insertion section is greater than the inside, it can also be supplemented inward through the through holes on the insertion section.

[0035] 5. When maintaining the planted seed sand barrier of the present invention, only need to inject water into the planting pipe to soak and expand the sand-preventing and vegetation-growing block. Most of the water is enclosed inside the planting pipe, and the water resource loss is less, solving the biggest problem of water shortage in desert plant planting. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0048] Example 1

[0049] Such as Figures 1 - 11As shown, a sand barrier planting device includes a main pipe 1 and a docking member 2. The upper and lower ends of the main pipe 1 are open, as Figure 3 shown. A docking hole 3 is provided on the docking member 2. The main pipe 1 is installed at the top of the docking member 2, and the docking hole 3 communicates with the bottom opening of the main pipe 1. A leveling plate 4 is installed on one side of the docking member 2;

[0050] It further includes a plurality of planting pipes 5 slidably connected in the inner cavity of the main pipe 1. Specifically: as Figure 1 and Figure 5 shown, the inside of the planting pipe 5 is divided into a growth section 8, a clamping section 9, and a piercing section 10 from top to bottom. A sand prevention and vegetation-growing block 32 is clamped on the inner wall of the growth section 8. The clamping section 9 is frustum-shaped. The bottom of the planting pipe 5 is spiked. A limiting edge 11 is fixedly sleeved on the outer wall of the growth section 8, and the limiting edge 11 is slidably connected with the inner wall of the main pipe 1; A plurality of through holes are provided on the piercing section 10;

[0051] As Figure 11 shown, the plurality of planting pipes 5 located in the main pipe 1 are stacked in a head-to-tail plug-in form, so as to increase the storage capacity of the planting pipes 5 in the main pipe 1.

[0052] As Figure 6 、 Figure 7 shown, a limiting structure is provided on the inner wall of the docking hole 3 for limiting the planting pipes 5 in the inner cavity of the main pipe 1;

[0053] As Figures 8 - 10 shown, a pressing structure is provided on one side of the main pipe 1 for extruding the planting pipes 5 from the inner cavity of the main pipe 1.

[0054] Furthermore, as Figure 3 shown, a plurality of docking plates 6 are fixedly connected to the bottom of the outer wall of the main pipe 1. The plurality of docking plates 6 are fixedly connected to the top of the docking member 2 through first docking bolts 7. During maintenance, only by removing the first docking bolts 7 can the main pipe 1 and the docking member 2 be quickly separated, improving the disassembly efficiency;

[0055] Furthermore, as Figure 4 shown, a slot 28 is provided at the bottom of one side of the docking member 2. A docking plug 29 corresponding to the slot 28 is provided on one side of the leveling plate 4. The docking plug 29 is inserted into the corresponding slot 28 and fixedly connected to the docking member 2 through a second docking bolt 30. During maintenance, only by removing the second docking bolts 30 can the leveling plate 4 and the docking member 2 be quickly separated, improving the disassembly efficiency. During planting, the staff can level the soil through the leveling plate 4 without carrying additional leveling tools. After leveling, the bottom of the leveling plate 4 is attached to the leveled ground, and by stepping on the top of the leveling plate 4, the main pipe 1 and the docking member 2 can be prevented from shaking during planting, improving the stability during planting.

[0056] Further, as Figure 6 and Figure 7 shown, two first avoidance grooves 12 are symmetrically formed on the inner wall of the docking hole 3, and a limiting structure is arranged 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. The support rod 13 is fixedly sleeved on the docking shaft 15. A torsion spring shaft rod 16 is installed on one side of the first avoidance groove 12 away from the docking shaft 15. The torsion spring 14 is sleeved on the torsion spring shaft rod 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;

[0057] Combined with 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 lowermost end in the main pipe 1.

[0058] Further, as Figure 1 、 Figure 8 and Figure 9 shown, the pressing structure includes a hand-held rod 17 and a force transmission rod 18. A limiting block 19 is arranged on one side of the main pipe 1. A limiting sliding groove 20 is formed in the limiting block 19. One end of the hand-held rod 17 is slidably connected in the limiting sliding groove 20. The force transmission rod 18 is slidably connected with the limiting block 19, and the top end of the force transmission rod 18 penetrates through the limiting block 19 and is fixedly connected with the hand-held rod 17. A compression spring 21 is fixedly connected to the bottom of the limiting block 19. A connecting ring 22 is fixedly connected to the rod body of the force transmission rod 18. The bottom end of the compression spring 21 is fixedly connected with the connecting ring 22.

[0059] Further, an auxiliary hand-held rod 27 is fixedly connected to the side of the main pipe 1 away from the hand-held rod 17. The force transmission rod 18 and the auxiliary hand-held rod 27 are hollow inside, so as to reduce the overall weight.

[0060] Further, combined with Figure 2 、 Figure 3 、 Figure 8 and Figure 10 , a pushing groove 23 is formed at one end of the main pipe 1 close to the docking part 2. A second avoidance groove 24 communicating with the pushing groove 23 is formed on one side of the docking part 2. A pressing plate 25 is slidably connected to the bottom end of the force transmission rod 18. One end of the pressing plate 25 slidably penetrates out of the pushing groove 23, and the bottom of the pressing plate 25 abuts against the upper surface of the limiting edge 11 of the planting pipe 5 at the lowermost end in the main pipe 1. The arranged second avoidance groove 24 can prevent the pressing plate 25 from interfering with the docking part 2 when moving downward.

[0061] Specifically: during planting, the staff first levels the soil through the leveling plate 4. After leveling, the bottom of the leveling plate 4 is attached to the leveled ground, and the top of the leveling plate 4 is stepped on. Then, one hand holds the auxiliary grip rod 27, and the other hand holds the hand grip rod 17 and pushes the hand grip rod 17 downward. The hand grip rod 17 slides downward along the limit chute 20. At the same time, the hand grip rod 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 chute 23. The pressing plate 25 presses downward on the limit edge 11, thereby extruding the planting tube 5 from the main tube 1. During the extrusion process, the piercing section 10 of the planting tube 5 will first pierce into the soil. As the pressing plate 25 is pressed downward, the limit edge 11 on the planting tube 5 will pass through the docking hole 3. At this time, since the piercing section 10 has pierced into the soil and the limit edge 11 is located above and below the soil and no longer moves downward and middleward, 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 part of the planting tube 5 below the limit edge 11 is pressed into the soil;

[0062] Among them, when the force transmission rod 18 moves downward, the compression spring 21 is stretched. After 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 pressing plate 25. During the pulling process, the stretched compression spring 21 will contract and reset, thereby assisting in driving the force transmission rod 18 to reset through the connecting ring 22;

[0063] During the extrusion of the planting tube 5, the outer wall of the clamping section 9 and the limit edge 11 will press on the support rod 13, causing the support rod 13 to rotate into the first avoidance groove 12 to facilitate the removal of the planting tube 5 from the docking hole 3. During the rotation process, the support rod 13 will press on the torsion spring 14. At this time, the torsion spring 14 is in a compressed state. When the planting tube 5 completely moves out of the docking hole 3, the compressed torsion spring 14 at this time will reset and push the corresponding support rod 13 to reset.

[0064] Embodiment 2

[0065] As Figures 1 - 11 shown, the following improvements are made in this embodiment on the basis of Embodiment 1: Further, as shown in Figure 3 、 Figure 10 shown, a displacement groove 26 is provided on the pressing plate 25, and the bottom end of the force transmission rod 18 is slidably connected to the displacement groove 26. Specifically: after the pressing plate 25 is reset, the pressing plate 25 is pulled outward. At this time, the plate body of the pressing plate 25 located in the main tube 1 will move into the push chute 23. At this time, the planting tube 5 above the pressing plate 25 will slide downward. The provided support rod 13 will abut against the outer wall of the clamping section 9 of the lowermost 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 pressing plate 25 is pushed inward to reset it.

[0066] Further, asFigure 1 As shown in the figure, transparent windows 31 corresponding to a plurality of limiting edges 11 are provided on the pipe wall of the main pipe 1, so that the staff can intuitively understand the number of planting pipes 5 in the main pipe 1.

[0067] In summary, the working process of the present invention is as follows:

[0068] When planting the seed sand barrier, the staff first levels the soil through the leveling plate 4. After leveling, the bottom of the leveling plate 4 is attached to the leveled ground, and the top of the leveling plate 4 is stepped on. Then, one hand holds the auxiliary grip rod 27, and the other hand holds the grip rod 17 and pushes the grip rod 17 downward. As a result, the pressing plate 25 slides downward along the pushing groove 23, and the pressing plate 25 presses the limiting edge 11 downward, so as to extrude the planting pipe 5 from the main pipe 1. During the extrusion process, the piercing section 10 of the planting pipe 5 will first pierce into the soil. As the pressing plate 25 is pressed downward, the limiting edge 11 on the planting pipe 5 will pass through the docking hole 3. At this time, since the piercing section 10 pierces into the soil, the soil will limit the piercing section 10 to prevent the planting pipe 5 from shaking. As the pressing plate 25 is pressed downward, the part of the planting pipe 5 below the limiting edge 11 is pressed into the soil;

[0069] After the seed sand barrier is planted, the grip rod 17 is pulled upward to reset the grip rod 17, the force transmission rod 18 and the pressing plate 25. After the pressing plate 25 is reset, the pressing plate 25 is pulled outward. At this time, the plate body of the pressing plate 25 located in the main pipe 1 will move into the pushing groove 23. At this time, the planting pipe 5 above the pressing 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 lowermost planting pipe 5. Then, the pressing plate 25 is pushed inward to reset it for the next planting.

[0088] Further, the preparation method of the sand prevention and vegetation planting block 32 is as follows: After mixing the matrix and sand prevention seeds evenly, press them into a cylindrical sand prevention and vegetation planting block 32. The amount of sand prevention seeds in each sand prevention and vegetation planting block 32 is 5 grains. The diameter of the sand prevention and vegetation planting block 32 is 4 - 4.5 cm, and the height is 1.5 - 2.2 cm.

[0089] Further, the water retaining agent is polyacrylamide; the seed initiator is naphthaleneacetic acid; the microbial inoculum is Trichoderma asperellum and arbuscular mycorrhizal fungi. According to the mass ratio, Trichoderma asperellum: arbuscular mycorrhizal fungi = 1:1.

[0090] Further, after planting, inject water into the planting tube 5 to soak and expand the sand prevention and vegetation planting block 32 to complete normal watering and maintenance.

[0091] Comparative Example 1

[0092] The difference between this comparison and Example 5 is that the seed sand barrier is planted by a common planting method, that is, after digging the soil with a spade, the sand prevention and vegetation planting block 32 is buried in the sand and watered for maintenance.

[0093] Comparative Example 2

[0094] The difference between this comparison and Example 5 is that the seed initiator is not added to the matrix.

[0095] Comparative Example 3

[0096] The difference between this comparison and Example 5 is that the water retaining agent is not added to the matrix.

[0097] Comparative Example 4

[0098] The difference between this comparison and Example 5 is that the mineral source humic acid is not added to the matrix.

[0099] Comparative Example 5

[0100] The difference between this comparative example and Example 5 is that attapulgite clay is not added to the substrate.

[0101] Comparative Example 6

[0102] The difference between this comparative example and Example 5 is that the horizontal spacing of the sand prevention vegetation blocks 32 is 2 m and the vertical spacing is 2 m.

[0103] Comparative Example 7

[0104] The difference between this comparative example and Example 5 is that the horizontal spacing of the sand prevention vegetation blocks 32 is 0.5 m and the vertical spacing is 0.5 m.

[0105] Experimental part

[0106] In the Tengger Desert, the experimental plots were planted according to the schemes of Examples 3 - 5 and Comparative Examples 1 - 5. One month later, 100 sand prevention vegetation blocks 32 were randomly selected, and their emergence rates were counted. See Table 1. In Table 1, if one plant germinated in the sand prevention vegetation block 32, it was considered to have survived.

[0107] Table 1 Experimental emergence observation record table

[0108]

[0109] As can be seen from Table 1, because the technical solutions of the present invention were adopted in Examples 3 - 5, the highest survival rate after 21 days was 97%, achieving very good technical effects.

[0110] In Comparative Example 1, because an existing scheme was adopted, due to long - term wind and sand invasion, the sand depth outside the sand prevention vegetation blocks 32 was uneven, and the emergence rate was also very low. On the other hand, as soon as the seedlings germinated, they were invaded by wind and sand, resulting in a large number of deaths as soon as they germinated. Not only a large amount of manpower and water resources were wasted, but the final survival rate was less than half.

[0111] In Comparative Examples 2 - 4, because the seed initiator, water - retaining agent, and mineral - source humic acid were lacking in the substrate, the germination of seeds was affected, and the final results were not very satisfactory.

[0112] In Comparative Example 5, because attapulgite clay was lacking, when being pressed into vegetation blocks, due to the influence on the adhesiveness, when it was clamped to the sand barrier planting device, a large number of breakage situations occurred, ultimately resulting in the loss of nutrients and seeds, and the survival rate was seriously affected.

[0113] In Comparative Examples 6 - 7, the initial emergence effect was good. However, in the subsequent experiments, it was observed that when the spacing was too small, the growth space of the seedlings was affected and their growth was weak; when the spacing was too large, the invasion of flowing sand could not be effectively prevented.
