Description

Technical Field

[0001] The invention relates to the field of slope protection, and in particular to a water and soil stabilization protection slope based on intercropping of ophiopogon japonicus in a tea garden. Background Art

[0002] A soil and water stabilization slope protection refers to a technical system that reinforces and protects slope soil through the combined synergy of engineering structures and vegetation systems. Its core functions include using retaining structures, anchors, etc. to resist lateral displacement of soil; reducing pore water pressure through diversion, interception, infiltration, etc.; and using vegetation roots to consolidate soil and the canopy to intercept precipitation, forming a sustainable soil and water conservation barrier.

[0003] In the existing technology, traditional slope support technology mainly includes single or combined structures such as retaining walls, facing walls, anchor frame beams, and drainage systems. Its core goal is to resist soil sliding through rigid or semi-rigid structures, and at the same time reduce pore water pressure through drainage facilities. The bottom drainage ditch mostly adopts a linear design, and the end is connected to the sedimentation tank, but there is a lack of graded reduction measures for water flow energy. The sedimentation problem is prominent, and the ditch is easily collapsed by water erosion. Although the vegetation root reinforcement mechanism is introduced, there is a lack of systematic coordinated design between the vegetation planting trough and the drainage structure. The configuration ratio and spatial layout of functional shrubs and herbaceous plants are unreasonable, and it is difficult to take into account soil consolidation, diversion and ecological benefits. The above defects lead to problems such as poor drainage, structural instability, and low ecological benefits in the traditional slope support system. There is an urgent need for a new type of partitioned support structure that integrates efficient drainage, mechanical reinforcement and ecological restoration functions. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a water and soil stabilization protection slope based on intercropping of Ophiopogon japonicus in tea gardens.

[0008] In some embodiments, the end of the first drainage trough provided on the lowest step of the stepped planting area is connected to the drainage ditch at the bottom of the slope, and second concrete baffles are provided on both sides of the drainage ditch at the bottom of the slope.

[0009] In some embodiments, the lower boundary of the slope top buffer zone is flush with the upper boundary of the highest step platform of the stepped planting area, and the slope top buffer zone is planted with plants with a width of 1-1.2 meters, which are composed of tall herbaceous plants.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and examples. It is particularly noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are only some embodiments of the present invention and are not intended to be exhaustive. All other embodiments obtained by those of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present invention.

[0019] The present invention provides a water and soil stabilization protection slope based on intercropping of ophiopogon in a tea garden. The present invention constructs a multi-level vegetation system through a horizontal partition support structure and a vertical layered structure, thereby increasing the diversity of the tea garden ecosystem and being beneficial to ecological balance and biodiversity protection. As a traditional Chinese medicine, intercropping of ophiopogon not only enhances the soil and water conservation effect, but also increases the economic benefits of the tea garden. The reasonable planting layout and vegetation selection enhance the overall landscape effect of the tea garden and promote the development of rural tourism and leisure agriculture.

[0020] See Figure 1-5 , this embodiment provides a water and soil stabilization protection slope based on interplanting ophiopogon in tea garden, including a horizontal partition support structure 1 and a vertical layered structure, the horizontal partition support structure 1 includes a stepped planting area 11, a slope top buffer zone 12, a slope bottom drainage ditch 13 and a grit chamber 14, the stepped planting area 11 is continuously distributed along the slope contour line direction, the slope top buffer zone 12 is adjacent to the slope top edge, the slope top buffer zone 12 extends to the highest level stepped planting area 11, the slope bottom drainage ditch 13 is located in the slope bottom area, the slope bottom drainage ditch 13 is arranged perpendicular to the contour line direction, and the slope bottom drainage ditch 13 is connected to the lowest level stepped planting area 11 The grit chamber 14 is connected to each other, and is arranged at the end of the drainage ditch 13 at the bottom of the slope, and is connected to the drainage ditch 13 at the bottom of the slope; the vertical layered planting structure 2 includes an upper planting structure 21, a middle planting structure 22 and a lower planting structure 23. The upper planting structure 21 is composed of single tea trees, and the row spacing of tea trees is 2-3 meters, and the spacing between tea trees is 1.2-1.5 meters. The middle planting structure 22 is composed of Ophiopogon japonicus plants, which are planted in double rows between the rows of tea trees. The planting density of Ophiopogon japonicus seedlings is 120-150 plants per square meter, and the depth of Ophiopogon japonicus seedlings into the soil is 8-12 cm; the lower planting layer is covered with barren-resistant herbaceous plants on the slope surface.

[0021] In this embodiment, first, step-type planting areas 11 are continuously set along the contour line of the slope. These planting areas are formed by trimming the slope. The height and width of each step are adjusted according to the slope gradient and soil conditions to ensure soil stability and suitability for plant growth. There is enough space for planting and maintaining tea trees and Ophiopogon japonicus. The edges of the steps are reinforced with stones or concrete to prevent soil erosion. The top of the slope buffer zone 12 is adjacent to the top edge of the slope. Its width is usually 2-3 meters. It is used to slow down the water flow and prevent runoff from directly eroding the top soil. Low shrubs and herbaceous plants, such as Amorpha fruticosa and Bermuda grass, are planted to Enhance rainwater infiltration and slow down surface runoff speed, protect the soil on the top of the slope from erosion, and make a smooth transition from the buffer zone to the highest stepped planting area 11 to ensure that water flows smoothly into the next level area. The slope bottom drainage ditch 13 is located in the slope bottom area. The width and depth are designed according to the slope catchment area and rainfall intensity to ensure that the slope runoff is effectively removed. A drainage ditch is excavated in the slope bottom area, and a grit chamber 14 is built at the end of the drainage ditch to precipitate the sediment carried in the water to prevent downstream blockage. The grit chamber 14 is cleaned regularly to maintain its effective function.

[0022] In this embodiment, a vertical layered planting structure 2 is implemented in the stepped planting area 11. The upper planting structure 21 is composed of single tea trees, with a row spacing of 2-3 meters and a spacing of 1.2-1.5 meters between tea trees to ensure that the tea trees receive sufficient light and nutrients. The middle planting structure 22 is composed of Ophiopogon japonicus plants, which are planted in double rows between the rows of tea trees, with a planting density of 120-150 plants per square meter. The depth of Ophiopogon japonicus seedlings into the soil is controlled at 8-12 cm to ensure that their root systems can fully develop and absorb water and nutrients from the soil. The lower planting layer is covered with barren-resistant herbaceous plants (such as Bermuda grass, white clover, etc.) covering the surface of the slope. These plants can fix the soil, prevent soil erosion, and increase the biodiversity of the slope.

[0023] In this embodiment, an effective soil and water conservation system is formed through the combination of a stepped planting area 11, a top-of-slope buffer zone 12, a bottom-of-slope drainage ditch 13, and a grit chamber 14. The top-of-slope buffer zone 12 slows down the water flow, reducing the impact of runoff on the top of the slope. The stepped planting area 11 increases the soil's ability to resist erosion through the plant root system and the physical structure of the soil. The bottom-of-slope drainage ditch 13 and the grit chamber 14 effectively remove and deposit silt from the runoff, preventing it from entering the downstream water body. In the vertical layered planting structure 2, the upper tea trees use their vast root network to stabilize the soil, reducing soil erosion. The middle-layered Ophiopogon japonicus plants cover the ground with dense roots and lush leaves, reducing the direct impact of rainwater on the soil and increasing the soil organic matter content. The lower layer of barren-tolerant herbaceous plants further stabilizes the soil, preventing soil erosion and promoting soil microbial activity. By intercropping Ophiopogon japonicus and covering with barren-tolerant herbaceous plants, the biodiversity of the tea garden is increased, providing a habitat for insects, birds, and other organisms, and promoting the balanced development of the ecosystem. The roots of Ophiopogon japonicus secrete growth hormones and trace elements, promoting soil enzyme activity and improving soil fertility. Furthermore, the fallen branches and leaves of Ophiopogon japonicus and other barren-tolerant herbs increase soil organic matter content and improve soil structure. As a traditional Chinese medicine, Ophiopogon japonicus' roots absorb harmful substances such as heavy metals from the soil, reducing their contamination of tea plants. Furthermore, the growth of Ophiopogon japonicus and other barren-tolerant herbs improves the microclimate of tea gardens, increasing the photosynthetic efficiency of tea leaves and thus enhancing tea quality.

[0024] In this embodiment, by implementing the horizontal partition support structure 1 and the vertical layered planting structure 2, the soil and water loss in the tea garden is effectively controlled. The combination of the stepped planting area 11, the slope top buffer zone 12, the slope bottom drainage ditch 13 and the sedimentation pond 14 forms an effective soil and water conservation system, reducing the scouring and erosion of the soil by runoff; at the same time, the growth of Ophiopogon japonicus and barren-resistant herbaceous plants further stabilizes the soil and improves the soil's ability to resist scouring. Interplanting Ophiopogon japonicus and covering barren-resistant herbaceous plants increase the biodiversity of the tea garden and promote the balanced development of the ecosystem. The growth of these plants provides habitats for insects, birds and other organisms, enriching the biological community structure of the tea garden; at the same time, the root systems of Ophiopogon japonicus and barren-resistant herbaceous plants can improve soil structure, increase soil fertility, and provide a good soil environment for the growth of tea trees. By implementing the soil and water stabilization and protection slope technology of interplanting Ophiopogon japonicus in tea gardens, not only the soil and water conservation capacity and ecological benefits of the tea garden are improved, but also the quality of tea and the increase in yield are promoted. As a traditional Chinese medicine, Ophiopogon japonicus has high economic value. At the same time, the improvement of the ecological environment of tea gardens has also improved the market competitiveness of tea, bringing more economic benefits to tea farmers. Furthermore, in some embodiments, a first drainage groove 111 is provided at the bottom of each step of the stepped planting area 11, and a second drainage groove 112 is provided at the top of each step of the stepped planting area 11. The first drainage groove 111 is longitudinally connected to the second drainage groove 112 to form a stepped drainage groove.

[0025] In this embodiment, a first drainage trough 111 is provided at the bottom of each step for collecting and guiding the rainwater runoff on the step. At the same time, a second drainage trough 112 is provided at the top of each step, which is longitudinally connected to the first drainage trough 111 to form a stepped drainage trough system. This design allows rainwater to flow down step by step along the steps, effectively reducing the scouring force of runoff on the soil. The stepped drainage trough system consists of a first drainage trough 111 and a second drainage trough 112, which are longitudinally connected to form a set of efficient rainwater collection and guidance system. During rainfall, rainwater is first collected in the second drainage trough 112 at the top of each step, and then flows down step by step along the stepped drainage trough system to the drainage ditch 13 at the bottom of the slope. This design not only effectively reduces the scouring force of rainwater on the soil, but also allows rainwater to be more evenly distributed over the entire slope, promoting the growth and development of plants.

[0026] In this embodiment, a complete three-level diversion system is formed by setting the first drainage trough 111 and the second drainage trough 112 to form a slope top buffer zone 12 → a drainage trough at the top of the step → a transverse drainage trough inside the step → a drainage trough at the bottom of the step → a drainage ditch at the foot of the slope → a sedimentation tank 14. The soil and water loss in the tea garden is effectively controlled, the scouring and erosion of the soil by runoff is reduced, and the soil's anti-scouring ability is improved, thereby effectively protecting the water and soil resources of the tea garden. The stepped planting area 11 disperses the lateral pressure of the soil by reducing the slope in stages. The drainage trough and the concrete baffle jointly limit the slope runoff scouring energy and play an effective supporting role. The drainage facilities at each level and the vegetation root system form a "hard-soft" composite support system, which significantly improves the slope's anti-slip ability.

[0027] Furthermore, in this embodiment, first concrete baffles 113 are provided on both sides of the second drainage trough 112 .

[0028] In this embodiment, a second drainage trough 112 is provided at the top of each step, with first concrete baffles 113 installed on both sides thereof. These baffles not only serve to fix the second drainage trough 112, but also effectively prevent rainwater runoff from splashing out of the trough during the flow, further reducing the scouring of the soil. The second drainage trough 112 is longitudinally connected to the first drainage trough 111 to form a stepped drainage trough system, which effectively guides rainwater to flow down step by step. The first concrete baffles 113 are installed on both sides of the second drainage trough 112, playing a key protective role. They can effectively prevent rainwater runoff from splashing out of the trough during the flow, avoiding direct scouring of the soil by runoff. At the same time, these baffles can also serve to fix the second drainage trough 112, preventing it from shifting or being damaged under the scouring of rainwater.

[0029] In this embodiment, a comprehensive soil and water conservation system is formed through the combination of the stepped planting area 11, the top buffer zone 12, the bottom drainage ditch 13, the grit chamber 14, and the stepped drainage trough (including the first concrete baffle 113). The top buffer zone 12 slows water flow, reducing runoff impact on the top of the slope. The stepped planting area 11 enhances soil erosion resistance through the plant root system and the physical structure of the soil. The stepped drainage trough system effectively guides rainwater runoff and prevents runoff from splashing through the first concrete baffle 113, further reducing soil erosion. The bottom drainage ditch 13 and grit chamber 14 further remove and deposit sediment from the runoff.

[0030] Furthermore, in some embodiments, the end of the first drainage trough 111 provided on the lowest step of the stepped planting area 11 is connected to the slope bottom drainage ditch 13 , and second concrete baffles 131 are provided on both sides of the slope bottom drainage ditch 13 .

[0031] In this embodiment, the end of the first drainage trough 111 of the lowest step is connected to the bottom drainage ditch 13, ensuring that rainwater runoff can smoothly flow into the bottom drainage ditch 13 and further discharge from the slope surface. Second concrete baffles 131 are provided on both sides of the bottom drainage ditch 13. These baffles serve to fix the bottom drainage ditch 13, prevent runoff from eroding the ditch wall, and prevent mud and sand from entering the drainage ditch.

[0032] In this embodiment, during rainfall, rainwater is first collected in the second drainage trough 112 at the top of each step of the stepped planting area 11, and then flows down step by step along the stepped drainage trough system to the first drainage trough 111 of the lowest step. The end of the first drainage trough 111 is connected to the slope bottom drainage ditch 13, and the rainwater runoff flows smoothly into the slope bottom drainage ditch 13, and finally discharges from the slope surface after sedimentation through the sedimentation tank 14. The entire drainage system is efficient and smooth, effectively reducing the scouring and erosion of soil by rainwater. The second concrete baffles 131 are installed on both sides of the slope bottom drainage ditch 13, playing a key protective role. They can effectively fix the slope bottom drainage ditch 13 to prevent it from shifting or being damaged by rainwater scouring. At the same time, these baffles can also prevent the runoff from scouring the ditch wall and the entry of sediment, keeping the slope bottom drainage ditch 13 unobstructed and clean.

[0033] Furthermore, in some embodiments, the lower boundary of the slope top buffer zone 12 is flush with the upper boundary of the highest step platform of the stepped planting area 11, and the slope top buffer zone is planted with plants with a width of 1-1.2 meters, which are composed of tall herbaceous plants.

[0034] In this embodiment, the slope top buffer zone 12 is located adjacent to the slope top edge, has a width of 1-1.2 meters, and is flush with the upper edge of the highest step platform of the stepped planting area 11. Tall herbaceous plants, such as reeds and Miscanthus sinensis, are planted within the buffer zone. These plants, with their tall stems and dense leaves, effectively slow water flow and prevent runoff from directly eroding the slope top soil. The tall herbaceous plants planted within the slope top buffer zone 12 effectively slow water flow and reduce the scouring force of runoff, thereby protecting the slope top soil from erosion. Furthermore, the roots of these plants increase the soil's resistance to erosion, further improving the stability of the slope top.

[0035] Furthermore, in some embodiments, the height between each step of the stepped planting area 11 is 15-20 centimeters and the width is 1-1.5 meters.

[0036] In this embodiment, the height between each step is designed to be 15-20 centimeters. This height range takes into account the slope and soil conditions of the tea garden slopes, ensuring that the steps are neither too steep nor too flat, thereby facilitating the smooth drainage of rainwater and the stable growth of plants. The width of each step is designed to be 1-1.5 meters. This width range ensures sufficient planting space for intercropping tea trees and lily-of-the-valley, while also facilitating management and maintenance. At the same time, the wider step width also helps increase soil stability and reduce the risk of soil erosion.

[0037] In this embodiment, the stepped design enables rainwater to change its direction multiple times when flowing through the slope, thereby slowing down the water flow rate and reducing the scouring force of the runoff. The wider step width and appropriate step height together increase the stability of the soil and reduce the risk of soil erosion. The stepped planting area 11 provides a diverse growth environment, which is conducive to the stable growth of plants such as tea trees and Ophiopogon japonicus.

[0038] Furthermore, in some embodiments, the upper planting structure 21 and the middle planting structure 22 are arranged in a staggered pattern.

[0039] In this embodiment, the upper planting structure 21 is primarily composed of individual tea trees, which are arranged at a predetermined row and plant spacing to form a stable upper planting layer. The upper planting structure 21 is composed of Ophiopogon japonicus plants, which are interplanted in double rows between the rows of tea trees to form a middle planting layer. The upper planting structure 21 and the middle planting structure 22 are horizontally staggered. Specifically, appropriate spaces are left between the rows of tea trees, and the Ophiopogon japonicus plants are interplanted within these spaces, forming a layout in which the tea trees and Ophiopogon japonicus intersect and support each other.

[0040] In this embodiment, the staggered layout allows the upper tea trees and the middle Ophiopogon japonicus to cover more soil surface together, reducing the exposed soil area, thereby reducing the scouring force of rainwater on the soil. The roots of the tea trees and Ophiopogon japonicus are intertwined in the soil, forming a strong root network, enhancing the stability of the soil, and reducing the risk of soil erosion. Tea trees and Ophiopogon japonicus release different chemical substances during their growth. These substances have an impact on the microecological environment in the tea garden and promote the formation of ecological balance. The staggered layout makes more full use of the space in the tea garden, which not only ensures the growth space of the tea trees, but also provides a suitable planting environment for Ophiopogon japonicus. Tea trees and Ophiopogon japonicus absorb different nutrients during their growth. The staggered layout helps to optimize the distribution and utilization of nutrients and improve the overall productivity of the tea garden.

[0041] Furthermore, in some embodiments, the Ophiopogon japonicus plants in the middle planting structure 22 are planted using a hole planting method, with a hole depth of 8-10 cm, and 2-3 Ophiopogon japonicus seedlings planted in each hole.

[0042] In this embodiment, as the main component of the middle planting structure 22, the Ophiopogon japonicus plant has a strong root system and dense leaves, which can effectively fix the soil, reduce soil erosion, and provide an ecological barrier for the tea garden. The Ophiopogon japonicus plant is planted using the hole planting method, that is, a hole of a certain depth and diameter is first dug in the soil, and then the Ophiopogon japonicus seedlings are planted therein. The depth of the hole is designed to be 8-10 cm. The selection of this depth range takes into account the root development requirements of the Ophiopogon japonicus plant and the physical properties of the soil, aiming to ensure that the root system of the Ophiopogon japonicus plant can fully extend and absorb water and nutrients in the soil. 2-3 Ophiopogon japonicus seedlings are planted in each hole. The selection of this planting density not only ensures that the competition between the Ophiopogon japonicus plants is moderate, but also makes full use of soil resources, thereby improving the coverage of the Ophiopogon japonicus plants and the soil and water conservation effect.

[0043] In this embodiment, the appropriate hole depth provides sufficient growth space for the root system of the Ophiopogon japonicus plant, helps the root system to stretch downward and absorb water and nutrients in the deep soil, thereby enhancing the stress resistance and productivity of the Ophiopogon japonicus plant. The hole planting method can reduce the damage of the Ophiopogon japonicus plant during the planting process and improve the survival rate. At the same time, the soil structure in the cave is relatively loose, which is conducive to the respiration and growth of the root system of the Ophiopogon japonicus plant. The Ophiopogon japonicus plant can effectively fix the soil and reduce soil erosion through its dense leaves and strong root system. The appropriate hole depth and planting density enable the Ophiopogon japonicus plant to form a stable covering layer in the tea garden, further improving the soil and water conservation effect. Through the reasonable hole depth and planting density design, the Ophiopogon japonicus plant can make fuller use of soil resources and improve the overall productivity of the tea garden. At the same time, the growth of the Ophiopogon japonicus plant can also promote nutrient circulation and ecological balance in the tea garden.

[0044] Furthermore, in some embodiments, a covering layer is provided on the surface of the middle planting structure 22, and the covering layer is made of a degradable ground film or straw braid.

[0045] In this embodiment, the covering layer is made of degradable ground film or straw woven fabric. Both materials offer excellent coverage and air permeability, effectively protecting the Ophiopogon japonicus plants in the middle planting structure 22 while preventing long-term soil pollution. The covering layer is positioned on the surface of the middle planting structure 22, above the Ophiopogon japonicus plants. This placement maximizes the protective effect of the covering layer while not affecting the photosynthesis and growth requirements of the Ophiopogon japonicus plants.

[0046] In this embodiment, the covering layer can effectively slow down the scouring force of rainwater on the soil, reducing the risk of soil erosion. The role of the covering layer is particularly significant in seasons with concentrated rainfall and heavy rainfall. The covering layer can reduce the evaporation of soil moisture, maintain soil moisture, and provide a suitable growth environment for Ophiopogon japonicus plants. In low temperature or drought seasons, the covering layer can play a role in heat preservation and moisture retention, providing a stable growth environment for Ophiopogon japonicus plants and promoting their healthy growth. The covering layer can inhibit the growth of weeds, reduce the competition of weeds on Ophiopogon japonicus plants, and improve the growth quality and yield of Ophiopogon japonicus plants. The covering layer will gradually release nutrients during the degradation process, providing organic matter to the soil and improving soil fertility. The covering layer provides a habitat for organisms such as microorganisms and insects in the tea garden, promoting the ecological balance of the tea garden. In addition, the functional units in each embodiment of the present invention can be integrated into a processing unit, or each unit can exist physically separately, or two or more units can be integrated into a single unit. The above-mentioned integrated unit can be implemented in the form of hardware or software functional units.
