Description

Technical Field

[0001] The utility model belongs to the technical field of shed films, and particularly relates to a covering structure for tea tree planting. Background Art

[0002] At present, tea trees are vulnerable to frost disasters in autumn and winter. In the light case, the bud leaves are scorched, and in the heavy case, the newly sprouted bud leaves are withered. At the same time, due to the low temperature in autumn and winter, tea trees are prone to diseases after being frozen.

[0003] In the prior art, tea is usually planted in a terraced field mode. The tea garden is located in the mountainous area and covers a large area, which makes it difficult to use traditional greenhouses for centralized protection of tea trees. Therefore, the current protection measure is to lay a covering film on each row of tea trees to keep the temperature. However, due to the windy and rainy weather environment in autumn and winter, there is a risk that the covering film will be blown away. To prevent this, growers have to install more fences to fix the covering film, which not only increases the workload of disassembling and installing the covering film, but also correspondingly increases the labor intensity. Content of the Utility Model

[0004] In view of this, the utility model provides a covering structure for tea tree planting, aiming to improve the stability of the covering film itself, so as to reduce the corresponding input of fences, thereby reducing the workload in the process of disassembling and installing the covering film.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] A covering structure for tea tree planting, including a covering film, the covering film is provided with a light conversion layer and a reinforcement layer, the light conversion layer is arranged on the upper surface of the reinforcement layer, a water injection port is opened on the light conversion layer, and the water injection port is used for injecting water into the reinforcement layer;

[0007] A water receiving port is arranged on the reinforcement layer for receiving the water injected by the water injection port. Among them, the water receiving port penetrates through the water injection port, a water bag is arranged at the edge of the reinforcement layer, and a water pipe is arranged between the water bag and the water receiving port. The water in the water receiving port is conveyed to the water bag by the water pipe, and the water bag is used for applying a downward pressure to the edge of the reinforcement layer after being filled with water.

[0008] As a preferred technical scheme, the upper end of the water bag is externally connected with a water pipe, and the inner wall of the water bag gradually inclines from top to bottom.

[0009] Furthermore, a water outlet pipe communicated with the water bag is arranged at the edge of the reinforcement layer, and a drip irrigation head is arranged at the output end of the water outlet pipe.

[0010] Furthermore, a thread adapted to the inner wall of the input end of the drip irrigation head is arranged on the outer wall of the output end of the water outlet pipe.

[0011] Further, it further includes a heat preservation layer. The lower surface of the reinforcement layer is connected to the upper surface of the heat preservation layer, and the lower surface of the heat preservation layer is used to cover the tea tree.

[0012] Further, a plurality of straps are provided on the lower surface of the heat preservation layer. Among them, the straps are used to wind around the external fence.

[0013] Further, the thickness ratio of the light conversion layer, the reinforcement layer and the heat preservation layer is 1:3:2.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] Through the setting of the water injection port and the water bag, after the planting personnel cover the covering film on the top of the tea tree, they only need to inject clean water into the water injection port, and the water receiving port will then guide the water flow into the water bag. As the water bag gradually fills and expands, the edge of the reinforcement layer will drive the edge of the covering film to sink towards the root of the tea tree. Through this process, the self-weight of the covering film is increased, and its stability on the tea tree is improved, effectively reducing the displacement of the covering film caused by the wind force. This not only helps to reduce the use of fences, but also reduces the labor intensity during the disassembly and assembly of the covering film. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following clearly and completely describes the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Example 1

[0024] In the prior art, tea plantations usually adopt a terraced layout. Tea gardens are mostly located in mountainous areas and cover a large area, which makes it difficult for traditional greenhouse greenhouses to be applicable to the centralized protection of tea trees. Therefore, the current protection measure is to cover each row of tea trees with a heat preservation film to maintain a suitable temperature. However, the climate conditions with strong winds and heavy rains in autumn and winter increase the risk of the heat preservation film being blown away by the wind. To avoid this problem, growers must install more fences to fix the covering film, which not only increases the workload of disassembling and installing the covering film, but also correspondingly increases the labor intensity.

[0025] Therefore, in order to solve the problems that the existing covering film is easily blown away by the wind during use and the high labor intensity caused by the large number of installed fences, and to achieve the function of improving the stability of the covering film and correspondingly reducing the amount of fence installation, the present utility model discloses a covering structure for tea tree planting. Refer to Figures 1-4 , including a covering film. The covering film is provided with a light conversion layer 1 and a reinforcement layer 2. The light conversion layer 1 is arranged on the upper surface of the reinforcement layer 2. Specifically, a water injection port 4 is opened on the light conversion layer 1. The water injection port 4 is used to inject water into the reinforcement layer 2. A water receiving port 6 is arranged on the reinforcement layer 2 for receiving the water injected by the water injection port 4. Among them, the water receiving port 6 is arranged inside the water injection port 4. A water bag 8 is arranged at the edge of the reinforcement layer 2, and a water pipe 7 is arranged between the water bag 8 and the water receiving port 6. The water in the water receiving port 6 is conveyed to the water bag 8 by the water pipe 7. The water bag 8 is used to apply a downward pressure to the edge of the reinforcement layer 2 after being filled with water;

[0026] After laying the covering film on the top of the tea tree, the planter can inject clean water into the water injection port 4, so that the water receiving port 6 can introduce the injected water into the water bag 8 through the water pipe 7. As the water continues to be injected into the water bag 8, the water bag 8 will expand by filling with water, so that the edge of the reinforcement layer 2 can drive the edge of the entire covering film to sink towards the root of the tea tree. Thus, by increasing the weight of the covering film itself, the covering film can be laid more stably on the tea tree, reducing the situation of the covering film being blown away by the wind, in order to reduce the investment in fences and lower the labor intensity;

[0027] Furthermore, both the water pipe 7 and the reinforcement layer 2 are made of elastic materials, such as PE materials. When the water bag 8 sinks due to being filled with water, the water pipe 7 will bend in the sinking direction of the water bag 8, so as to exert a certain clamping effect on both sides of the tea tree, which helps to improve the stability of the covering film. Secondly, the setting of the reinforcement layer 2 can also improve the overall toughness of the covering film.

[0028] In this embodiment, in order to improve the heat preservation effect on tea trees, the covering film further includes a heat preservation layer 3. The lower surface of the reinforcement layer 2 is connected to the upper surface of the heat preservation layer 3. The lower surface of the heat preservation layer 3 is used to cover the tea trees for heat preservation. Specifically, the heat preservation layer 3 can be made of EVA material. By directly attaching the heat preservation layer 3 to the top of the tea trees, it can play a role in heat preservation, thereby improving the cold resistance of the covering film and helping to prevent the tea trees from getting diseases due to frost.

[0029] In this embodiment, the light conversion layer 1 is provided with light conversion masterbatches mainly composed of rare earth doping. These light conversion masterbatches are evenly dispersed in the light conversion layer 1, enabling the light conversion layer 1 to convert ultraviolet light or blue light in the incident light into red light or green light, thereby providing a more suitable light spectrum for the tea trees, promoting their photosynthesis, and improving the quality and yield of the tea leaves.

[0030] In addition, the thicknesses of the light conversion layer 1, the reinforcement layer 2, and the heat preservation layer 3 can affect the light conversion efficiency, flexibility, and heat preservation performance of the covering film. In one embodiment, the thickness ratio of the light conversion layer 1, the reinforcement layer 2, and the heat preservation layer 3 is 1:3:2. Such a ratio can ensure that the covering film has good flexibility and heat preservation performance while providing sufficient light conversion efficiency.

[0031] In summary, when the covering film is laid on the top of the tea trees, the user first turns the side with the heat preservation layer 3 towards the tea trees, and then spreads the covering film on the top of the tea trees. At this time, the covering film will be laid on the tea trees in an arch shape, causing the edge of the reinforcement layer 2 with the water bag 8 to naturally droop towards the roots of the tea trees. Subsequently, the user can connect the head and tail of the covering film to the external fence, so that the covering film can be fixed on the tea trees. In order to enable the covering film to be smoothly connected to the external fence, a plurality of straps 10 are provided on the lower surface of the heat preservation layer 3. Among them, the straps 10 are used to bind to the external fence.

[0032] Embodiment Two

[0033] On the basis of Embodiment One, in order to further improve the growth efficiency of the tea trees, refer to Figure 3 , the present utility model further includes a drip irrigation head 5 for drip irrigation of the roots of the tea trees. Specifically, a water outlet pipe 9 communicating with the water bag 8 is provided at the edge of the reinforcement layer 2, and the drip irrigation head 5 is provided at the output end of the water outlet pipe 9;

[0034] In this embodiment, after the covering film is laid on the tea trees, the planter can inject water into the water bag 8 through the water injection port 4. As the water bag 8 fills with water and expands, the weight of the water bag 8 increases, making the covering film more stably fixed on the tea trees. At the same time, the water in the water bag 8 is delivered to the drip irrigation head 5 through the water outlet pipe 9, realizing the drip irrigation of the roots of the tea trees, thereby improving the utilization rate of the water in the water bag 8;

[0035] It should be noted that in the initial state, a sealing cover is provided at the drip irrigation opening of the drip irrigation head 5. In case of windy or rainy weather, the user can use the sealing cover to seal the drip irrigation head 5 after filling it with water, so as to prevent the covering film from reducing its own weight due to the leakage of water in the water bag 8. In sunny weather, the user can open the drip irrigation head 5 again, so that the drip irrigation head 5 can use the water in the water bag 8 to drip irrigate the tea trees, which helps to improve the growth efficiency of the tea trees;

[0036] Furthermore, in order to facilitate the user to replace the drip irrigation head 5 with different diameters, threads adapted to the inner wall of the input end of the drip irrigation head 5 are provided on the outer wall of the output end of the water outlet pipe 9. At the same time, when the user needs to remove the entire covering film from the tea tree, the user can directly rotate the drip irrigation head 5 to remove the drip irrigation head 5 from the water outlet pipe 9, so that the water in the water bag 8 can quickly drain out of the water outlet pipe 9, which is convenient for the storage of the covering film;

[0037] In addition, in order to improve the efficiency of the water in the water bag 8 draining out of the water outlet pipe 9, the upper end opening of the water bag 8 is externally connected to a water pipe 7, and the inner wall of the water bag 8 is gradually inclined from top to bottom, so that the water flow is more likely to concentrate and accelerate through the water outlet pipe 9 under the action of gravity. At the same time, through the V-shaped structure of the water bag 8, when the drip irrigation head 5 is sealed, the sinking gravity of the water in the water bag 8 can be more concentrated, thereby further enhancing the stability of the covering film.

[0038] In summary, combining Embodiment 1 and Embodiment 2, when the covering film is in use, first, the planter needs to select a covering film with a suitable size according to the planting area and shape of the tea trees. Before laying the covering film, it should be ensured that the top of the tea trees is clean and free of weeds, and the tea trees should be appropriately pruned so that the covering film can better fit the top of the tea trees.

[0039] Next, the side of the covering film with the heat preservation layer 3 is facing the tea trees, and then the covering film is laid on the top of the tea trees. At this time, the covering film will be laid on the tea trees in an arch shape, so that the edge of the reinforcement layer 2 with the water bag 8 will naturally droop towards the roots of the tea trees. The planter can inject water into the water bag 8 through the water injection port 4. As the water bag 8 fills with water and expands, the edge of the covering film will sink, thereby increasing the stability of the covering film.

[0040] After the covering film is laid, the planter needs to connect the head and tail of the covering film to the external fence to ensure that the covering film is fixed on the tea trees. At this time, the straps 10 on the lower surface of the heat preservation layer 3 can be tied to the external fence to further enhance the stability of the covering film.

[0041] In daily management, the planting staff need to regularly check the integrity of the covering film to ensure that there is no damage or water leakage. When drip irrigation is required for the tea trees, the planting staff can open the drip irrigation head 5 and use the water in the water bag 8 to carry out drip irrigation on the tea trees. After the drip irrigation is completed, if it is necessary to remove the covering film from the tea trees for maintenance or replacement, the planting staff can rotate the drip irrigation head 5, remove it from the water outlet pipe 9, and then drain the water in the water bag 8 to facilitate the storage and storage of the covering film.

[0042] Through the above method, the covering film can not only provide heat preservation, moisture preservation and light conversion functions, but also realize precise irrigation of the roots of tea trees through the combination of the water bag and the drip irrigation system, thereby promoting the growth efficiency of tea leaves. At the same time, the covering film increases its own weight to increase stability, so the investment in fences can be correspondingly reduced, which helps to reduce the labor intensity during the planting of tea trees.

[0043] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
