Abstract
Description
Technical Field
[0001] This utility model relates to the field of seedling cultivation technology, specifically a tree basin covering device. Background Technology
[0002] In the field of seedling cultivation technology, tree basin management is a crucial link, which directly affects the growth status and survival rate of seedlings. As the main activity area of the seedling root system, the quality of the environmental conditions of the tree basin has a direct impact on the growth of seedlings. In order to reduce water evaporation directly from the ground, suppress weed growth, prevent soil surface compaction, and maintain soil temperature balance, the current common practice is to lay mulch in the tree basin.
[0003] Common tree basin mulch materials, such as organic materials (like straw, sawdust, etc.) or inorganic materials (like plastic film, etc.), have two main drawbacks. First, these mulch materials are mostly easily decomposed, and their covering effect gradually weakens over time. New mulch materials need to be added regularly to maintain the thickness and effectiveness of the covering layer, which increases the workload and raises the cost of seedling management. Second, commonly used mulch materials are prone to displacement or loss when exposed to rainwater, especially during the rainy season or in windy areas, which seriously affects the retention effect of the mulch.
[0004] Therefore, this utility model proposes a tree basin covering device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a tree basin covering device to solve the above-mentioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A tree basin covering device includes a ring-shaped PVC covering body, which is composed of two detachable semi-rings. Each of the two semi-rings is provided with several anchor rods for inserting into the soil to fix the covering device. Channels are also evenly distributed on the two semi-rings for the seedlings to breathe and breathe and for water to permeate.
[0008] In one alternative: the semi-ring is hollow inside and drip irrigation holes are evenly distributed at the bottom of the semi-ring. One of the two semi-rings has a through hole on its mating side, and the other semi-ring has a connecting pipe corresponding to and adapted to the through hole on its mating side. Either of the two semi-rings has an injection port.
[0009] In one alternative: a sealing ring is provided in the through hole.
[0010] In one alternative embodiment: the covering device further includes two sets of opening and closing components corresponding to the two semi-rings respectively, for controlling the opening and closing of the drip irrigation holes. The opening and closing components include a mesh plate that slides up and down in the semi-rings. The mesh plate is provided with a sealing block that corresponds to each drip irrigation hole. A lead screw is threaded through the upper side of the semi-rings, and the lower end of the lead screw is rotatably connected to the mesh plate.
[0011] In one alternative: a support plate is inserted through the anchor rod, and a positioning bolt is provided on the support plate.
[0012] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:
[0013] 1. Assemble the two semi-ring pieces together at the trunk of the sapling. The trunk of the sapling is located in the inner circle of the PVC covering. Then, move the covering device down so that the anchor rod is inserted into the soil until the bottom side of the PVC covering contacts the soil. This achieves soil covering and protection for the root area of the sapling. It is firm, stable, and easy to use. Moreover, the PVC material has low biodegradability, good durability, and can be reused. This ensures the long-term use of the tree basin covering and reduces the cost of sapling cultivation.
[0014] 2. This covering device has the function of drip irrigation. When the two half-ring parts are assembled together, the connecting pipe is inserted into the through hole. Water or water-fertilizer mixture is added to one half-ring part through the injection port, and then enters the other half-ring part through the connecting pipe. The added water or water-fertilizer mixture is discharged through the drip irrigation hole to realize drip irrigation or slow-release drip irrigation of seedlings.
[0015] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Please see Figure 1 and Figure 2 A tree basin covering device includes a ring-shaped PVC covering body 1, which is composed of two detachable semi-rings 101. Each of the two semi-rings 101 is provided with several anchor rods 2 for inserting into the soil to fix the covering device. Channels 3 are also evenly distributed on the two semi-rings 101 for seedling respiration and water infiltration (such as rainwater entering the soil in the root area of the seedling through the channels 3).
[0024] Two semi-rings 101 are joined together at the trunk of the sapling to form a single unit. The sapling trunk is located in the inner circle of the PVC covering 1. Then, the covering device is lowered so that the anchor rod 2 is inserted into the soil until the bottom side of the PVC covering 1 contacts the soil, thus achieving soil covering and protection for the root area of the sapling. It is firm, stable, and easy to use. Moreover, the PVC material has low biodegradability, good durability, and can be reused, which not only ensures the long-term use effect of tree basin covering but also reduces the cost of sapling cultivation. It should be noted that the covering device is available in various specifications, that is, the inner and outer circles of the PVC covering 1 have different sizes. The appropriate covering device should be selected according to the actual thickness and size of the sapling. After the sapling grows to a certain extent, the appropriate covering device should be replaced in time to avoid affecting the growth of the sapling.
[0025] Furthermore, the two semi-rings 101 can be detached by means of bolt and nut combination, snap fastener, pin, etc., which is not limited in this application.
[0026] Please see Figures 1-3In one embodiment of the present invention, the semi-ring 101 is hollow inside, and drip irrigation holes 4 are evenly distributed at the bottom of the semi-ring 101. One of the two semi-rings 101 has a through hole 8 on its docking side, and the other semi-ring 101 has a connecting pipe 11 corresponding to and adapted to the through hole 8 on its docking side. Either of the two semi-rings 101 has an injection port 10.
[0027] In this embodiment, the covering device also has the function of drip irrigation. When the two semi-ring parts 101 are assembled together, the connecting pipe 11 is inserted into the through hole 8, and water or water-fertilizer mixture is added to one of the semi-ring parts 101 through the injection port 10. Then, the water or water-fertilizer mixture enters the other semi-ring part 101 through the connecting pipe 11. The added water or water-fertilizer mixture is discharged through the drip irrigation hole 4 to realize drip irrigation or slow-release drip irrigation of seedlings.
[0028] Furthermore, in this embodiment, a sealing ring is provided in the through hole 8, and the connecting pipe 11 is inserted into the through hole 8. The sealing ring wraps around the outer wall of the connecting pipe 11 to achieve a sealing effect, thereby preventing water or water-fertilizer mixture from leaking.
[0029] Furthermore, in this embodiment, a support plate 6 is installed on the anchor rod 2, and a positioning bolt 7 is installed on the support plate 6. When water or a water-fertilizer mixture is added to the PVC cover 1, its weight will increase significantly, thereby compressing the soil in the seedling root area and causing soil compaction. By setting the support plate 6 to support the outer ring of the soil in the seedling root area, when installing the cover device (the support plate 6 is initially located above the anchor rod 2), the cover device is moved down until the bottom side of the PVC cover 1 contacts the soil in the seedling root area. Then, the positioning bolt 7 is loosened to move the support plate 6 down until it contacts the ground. Then, the positioning bolt 7 is tightened to position the support plate 6. After completing all the support plate 6 operations as described above, the PVC cover 1 is supported, so that the bottom of the PVC cover 1 always maintains a light contact with the soil in the seedling root area, avoiding soil compaction caused by soil compression.
[0030] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the covering device further includes two sets of opening and closing components corresponding to the two semi-rings 101 respectively, for controlling the opening and closing of the drip irrigation holes 4. The opening and closing components include a mesh plate 5 that is slidably disposed in the semi-ring 101. The mesh plate 5 is provided with a sealing block 12 corresponding to the drip irrigation holes 4. Preferably, the sealing block 12 is made of rubber material. A lead screw 9 is threaded through the upper side of the semi-ring 101, and the lower end of the lead screw 9 is rotatably connected to the mesh plate 5.
[0031] In this embodiment, when the drip irrigation function is not used, the sealing block 12 is pressed tightly against the corresponding drip irrigation hole 4 to seal it and prevent soil particles and other impurities from entering the semi-ring 101. When the drip irrigation function is used, the mesh plate 5 is moved upward by rotating the screw 9, so that the sealing block 12 is disengaged from the corresponding drip irrigation hole 4, thereby opening the drip irrigation hole 4.
[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
