Description

Technical Field

[0001] This utility model relates to the field of agricultural ecological environment engineering technology, and in particular to an ecological transformation system for plant planting trenches and farmland drainage ditches. Background Technology

[0002] Currently, the prevention and control of non-point source pollution in farmland and the cultivation of biodiversity have become options for the development of ecological agriculture. Drainage ditches, as important flood control channels, are a crucial infrastructure for farmland. Traditional farmland drainage ditches, especially hard ditches constructed with materials such as concrete, masonry, or precast cement slabs, while offering advantages such as high drainage efficiency and structural stability, also bring significant environmental and ecological problems, such as reduced water self-purification capacity, decreased biodiversity, and poor landscape effects.

[0003] To restore the ecological function of drainage ditches, the common practice is to plant aquatic plants at the bottom of the ditches. In earthen drainage ditches, these plants can be planted directly, while in hard drainage ditches, the accumulated sediment is used for planting.

[0004] However, the above methods have obvious drawbacks: First, hard drainage ditches require periodic dredging, making planting difficult, and insufficient bottom mud makes it difficult for plant roots to anchor, and seedlings are easily washed away by the water flow; Second, planting in soil or silt-filled sections can easily lead to uncontrolled proliferation of aquatic plants. Many aquatic plants (such as irises, reeds, and cattails) have extremely strong reproductive capabilities. If planted directly in soil or bottom mud, their rhizomes will spread uncontrollably, encroaching on the water-carrying cross-section, seriously hindering water flow, and affecting the core function of the drainage ditch, even causing local siltation and rising water levels; Third, management and maintenance are inconvenient. After the plants grow freely, the amount of cleaning and pruning work is large, and it is easy to damage the structure of the ditch.

[0005] Therefore, there is an urgent need for a device that can effectively fix plants, limit the excessive spread of plant roots, and is easy to install and maintain, in order to solve the problems in the ecological transformation of drainage ditches. Utility Model Content

[0006] The purpose of this utility model is to provide an ecological transformation system for plant planting trenches and farmland drainage ditches to solve the problems existing in the prior art. It can effectively fix plants, limit the excessive spread of plant roots, and is easy to install and maintain.

[0007] To achieve the above objectives, this utility model provides the following solution: This utility model provides a plant planting trough, including a trough body, which is used to be placed at the bottom of a farmland drainage ditch. The trough body can accommodate a growth substrate and plants. The trough body is provided with a plurality of root outlet holes, which can connect the interior of the trough body with the exterior.

[0008] Preferably, the trough has a first convex section and a second convex section in sequence in the direction of the extension of the farmland drainage ditch. The first convex section protrudes in a first direction, and the second convex section protrudes in a second direction. The first direction is opposite to the second direction, and both the first direction and the second direction are perpendicular to the direction of the extension of the farmland drainage ditch.

[0009] Preferably, a plurality of hooks are fixedly provided on the tank.

[0010] Preferably, the trough includes a bottom plate, a first side plate, a second side plate, a first partition plate, and a second partition plate. The bottom ends of the first side plate, the second side plate, the first partition plate, and the second partition plate are all fixedly mounted on the bottom plate. The first side plate and the second side plate are parallel. The first side plate protrudes sequentially in the first direction and in the second direction along the extension direction of the farmland drainage ditch. The second side plate protrudes sequentially in the first direction and in the second direction along the extension direction of the farmland drainage ditch. The first partition plate and the second partition plate are parallel. One end of the first partition plate is fixedly connected to one end of the first side plate, and the other end of the first partition plate is fixedly connected to one end of the second side plate. One end of the second partition plate is fixedly connected to the other end of the first side plate, and the other end of the second partition plate is fixedly connected to the other end of the second side plate.

[0011] Preferably, the base plate is a rectangular plate, and the hooks are fixed at all four corners of the base plate.

[0012] Preferably, the length of the base plate in the direction of the farmland drainage ditch is 2.0m to 2.2m, and the width of the base plate is 300mm.

[0013] Preferably, the distance between the first side plate and the second side plate is 100mm~150mm, and the height of the first side plate, the height of the second side plate, the height of the first partition and the height of the second partition are all 100mm~150mm.

[0014] Preferably, a plurality of root outlet holes are evenly provided on both the first side plate and the second side plate.

[0015] Preferably, the diameter of the root outlet hole is 5mm to 15mm.

[0016] This utility model also provides an ecological transformation system for farmland drainage ditches, including several planting groups. All the planting groups are used to be placed sequentially at the bottom of the farmland drainage ditch in the direction of its extension. The distance between any two adjacent planting groups is greater than 10m. The length of each planting group is 20m to 50m. Each planting group includes several plant planting troughs as described above. All the plant planting troughs in each planting group are used to be placed sequentially at the bottom of the farmland drainage ditch in the direction of its extension.

[0017] The present invention achieves the following technical advantages over the prior art: This utility model provides a plant planting trough and an ecological transformation system for farmland drainage ditches. The trough is placed at the bottom of the farmland drainage ditch, filled with soil or other plant growth substrate, and planted with aquatic or wetland plants. The trough provides a stable growth environment and shelter for the seedlings, preventing them from being washed away by the water flow and achieving effective planting. This solves the problem of plants struggling to survive at the bottom of the ditch. It can also filter, adsorb, and absorb pollutants during drainage in farmland drainage ditches. Several root outlet holes are provided in the trough, connecting the inside of the trough to the outside. After the plants grow, only some fibrous roots can extend into the external water body through these holes to absorb nutrients and water, while the main root and more spreading rhizomes cannot penetrate, thus physically blocking the flow of pollutants. This method effectively controls the growth range of plant roots, cleverly confining the main body of the plant roots within the trench, thus controlling plant growth and eliminating the possibility of disorderly spread of plants on the bottom or slope of the canal. It fundamentally avoids the risk of excessive plant reproduction and waterway blockage, ensuring unobstructed water flow and guaranteeing the flood control and drainage functions of the drainage ditch. Simultaneously, the roots extending through the root outlet holes can purify the water, providing an attachment surface for aquatic microorganisms, enhancing the ecological value and biodiversity of the ditch, and ensuring the stable ecological benefits of the canal bottom. The modular design makes installation, inspection, cleaning, and plant replacement very convenient. When maintenance is needed, the entire planting trench can be removed for plant harvesting or replacement, simplifying the operation without damaging the canal structure, facilitating management, and significantly reducing later maintenance costs.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this utility model is to provide an ecological transformation system for plant planting trenches and farmland drainage ditches to solve the problems existing in the prior art. It can effectively fix plants, limit the excessive spread of plant roots, and is easy to install and maintain.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 like Figures 1 to 5 As shown, this embodiment provides a plant planting trough, including a trough body, which is used to be placed at the bottom of a farmland drainage ditch. The trough body can accommodate a growth substrate 1 and plants. A plurality of root outlet holes 2 are provided on the trough body, which can connect the inside of the trough body with the outside.

[0024] The plant planting trough provided in this embodiment, by placing the trough at the bottom of a farmland drainage ditch, and filling the trough with soil or other plant growth substrate 1, and planting aquatic or wetland plants, provides a stable growth environment and shelter for the seedlings, making them less likely to be washed away by the water flow, thus achieving effective planting and solving the problem of plants having difficulty surviving at the bottom of the ditch. It can also play a role in filtering, adsorbing, and absorbing pollutants during drainage in farmland drainage ditches. By having several root outlet holes 2 opened on the trough, the interior of the trough can be connected to the outside. After the plants grow, only some fibrous roots can extend into the external water body through the root outlet holes 2 to absorb nutrients and water, but the main root and the rhizomes with strong spreading ability cannot penetrate out, thereby effectively controlling the plant roots through physical barriers. The system cleverly confines the plant roots within the trench, controlling their growth and preventing uncontrolled spread on the canal bottom or slope. This fundamentally avoids the risk of excessive plant growth and waterway blockage, ensuring unobstructed water flow and maintaining the drainage canal's flood control and drainage functions. Simultaneously, the roots extending through the root outlet holes 2 purify the water, providing an attachment surface for aquatic microorganisms, enhancing the canal's ecological value and biodiversity, and ensuring stable ecological benefits at the canal bottom. The modular design makes installation, maintenance, cleaning, and plant replacement very convenient. When maintenance is needed, the entire planting trench can be removed for harvesting or replacement, simplifying the process without damaging the canal structure, facilitating management, and significantly reducing later maintenance costs.

[0025] It should be noted that the plants selected are generally low-growing aquatic or wetland plants, such as irises and calamus.

[0026] As a preferred embodiment of this invention, the tank body is made of high-density polyethylene, polypropylene, or other engineering plastics, which have the characteristics of corrosion resistance, aging resistance, and high strength. It is suitable for long-term underwater environments, has a simple structure, good durability, uses environmentally friendly and durable materials, has a long service life, and is suitable for widespread promotion.

[0027] In a preferred embodiment of this invention, the trough has a first lateral convex section and a second lateral convex section in sequence along the direction 9 of the extension of the farmland drainage ditch. The first lateral convex section protrudes towards the first direction 10, and the second lateral convex section protrudes towards the second direction 11. The first direction 10 and the second direction 11 are opposite to each other and are both perpendicular to the direction 9 of the extension of the farmland drainage ditch, so that the trough forms an "S"-shaped meandering planting chamber. This not only forms a full-section barrier zone on the ditch cross-section, extending the plant's action distance, but also effectively avoids "water blockage" caused by excessive plant growth, reducing negative impacts and ensuring the flood control and drainage function of the drainage ditch. An "S"-shaped barrier structure can be formed at the bottom of the ditch over a certain distance to absorb and filter drainage pollutants, improve the biodiversity of the farmland drainage ditch, and at the same time, the root system is effectively restricted to grow in the "S"-shaped meandering chamber of the trough. The "S"-shaped structure can effectively extend the root growth path in the trough, increase the fixation effect, and maximize the use of space in the trough.

[0028] As a preferred embodiment of this invention, a number of hooks 8 are fixedly provided on the trough. When placing or removing the plant planting trough provided in this invention, the hooks 8 can be hooked with a hook tool (such as a steel bar) and lifted out, which reduces maintenance costs. As a preferred embodiment of this invention, the hooks 8 are threadedly connected to the trough, which facilitates assembly and maintenance.

[0029] In a preferred embodiment of this invention, the tank includes a bottom plate 3, a first side plate 4, a second side plate 5, a first partition plate 6, and a second partition plate 7. The bottom ends of the first side plate 4, the second side plate 5, the first partition plate 6, and the second partition plate 7 are all fixedly mounted on the bottom plate 3. The first side plate 4 and the second side plate 5 are parallel. The first side plate 4 protrudes sequentially towards a first direction 10 and towards a second direction 11 in the direction 9 of the extension of the farmland drainage ditch. The second side plate 5 protrudes sequentially towards a first direction 10 and towards a second direction 11 in the direction 9 of the extension of the farmland drainage ditch. The first partition plate 6 and the second partition plate 7 are parallel. One end of the first partition plate 6 is fixedly connected to one end of the first side plate 4, and the other end of the first partition plate 6 is fixedly connected to one end of the second side plate 5. One end of the second partition plate 7 is fixedly connected to the other end of the first side plate 4, and the other end of the second partition plate 7 is fixedly connected to the other end of the second side plate 5. The structure is simple and easy to manufacture and use.

[0030] As a preferred embodiment of this invention, the base plate 3 is a rectangular plate, and hooks 8 are fixed at the four corners of the base plate 3 to facilitate deployment or withdrawal operations.

[0031] As a preferred embodiment of this invention, the length of the base plate 3 in the direction 9 extending from the farmland drainage ditch is 2.0m to 2.2m, which facilitates deployment or removal operations. The width of the base plate 3 is 300mm, which meets the construction requirements of high-standard farmland drainage ditches (the bottom width of the ditch is generally 300mm to 400mm).

[0032] As a preferred embodiment of this invention, the distance between the first side plate 4 and the second side plate 5 is 100mm~150mm, and the heights of the first side plate 4, the second side plate 5, the first partition 6, and the second partition 7 are all 100mm~150mm to avoid excessive height affecting drainage.

[0033] As a preferred embodiment of this invention, a plurality of root outlet holes 2 are evenly provided on both the first side plate 4 and the second side plate 5. The structure is simple and easy to manufacture and use.

[0034] As a preferred embodiment of this invention, the diameter of the root outlet hole 2 is 5mm to 15mm, which allows the fine roots of the plant to extend and absorb nutrients from the water, while effectively preventing the main root and thick rhizome from penetrating out, thereby confining the main root network of the plant inside the tank.

[0035] The plant planting troughs provided in this embodiment are first placed by cleaning the bottom of the target installation section of the farmland drainage ditch to keep the bottom flat. The growth substrate 1 (soil or dried ditch bottom mud) is then filled into the trough on the bank. Plants are planted during the filling process. Generally, 10 to 12 irises are planted in a single trough. Then, hooks (such as steel bars) are used to hook the hooks 8 and place the troughs stably on the bottom of the target installation section of the farmland drainage ditch. The bottom plates 3 of two adjacent troughs are connected, and multiple "S"-shaped troughs form a wave-shaped control structure.

[0036] Example 2 This embodiment provides an ecological transformation system for farmland drainage ditches, including several planting groups. All planting groups are placed sequentially at the bottom of the farmland drainage ditch along the extension direction 9. The distance between any two adjacent planting groups is greater than 10m. The length of the planting group is 20m to 50m. The planting group includes several plant planting troughs as described in Embodiment 1. All plant planting troughs in the planting group are placed sequentially at the bottom of the farmland drainage ditch along the extension direction 9.

[0037] The ecological transformation system for farmland drainage ditches provided in this embodiment involves placing a trough at the bottom of the drainage ditch. The trough is filled with soil or other plant growth substrate 1 and planted with aquatic or wetland plants. The trough provides a stable growth environment and shelter for the seedlings, preventing them from being washed away by the water flow and achieving effective planting. This solves the problem of plants struggling to survive at the bottom of the ditch. The system can filter, adsorb, and absorb pollutants during drainage. Several root outlet holes 2 are provided in the trough, connecting the inside of the trough to the outside. After the plants grow, only some fibrous roots can extend into the external water body through the root outlet holes 2 to absorb nutrients and water, while the main root and rhizomes with strong spreading ability cannot penetrate. This effectively controls pollutants through physical barriers. The plant root system cleverly confines the plant roots within the trench, controlling their growth and preventing uncontrolled spread on the canal bottom or slope. This fundamentally avoids the risk of excessive plant growth and waterway blockage, ensuring unobstructed water flow and maintaining the drainage canal's flood control and drainage functions. Simultaneously, the roots extending through the root outlet holes 2 purify the water, providing an attachment surface for aquatic microorganisms, enhancing the canal's ecological value and biodiversity, and ensuring stable ecological benefits at the canal bottom. The modular design makes installation, maintenance, cleaning, and plant replacement very convenient. When maintenance is needed, the entire planting trench can be removed for harvesting or replacement of plants, simplifying the process without damaging the canal structure, facilitating management, and significantly reducing later maintenance costs.
