[0024] This invention proposes a method for establishing vegetation in planting troughs based on the water flow path under photovoltaic panels.

[0025] Reference Figures 1 to 4 In one embodiment of the present invention, the vegetation establishment method of the planting trough 10 includes the following steps: S10. Excavate a placement trench in the target planting area 101, where the target planting area 101 is the water flow path area under the photovoltaic panel; S20. Place the planting trough 10 into the placement trough, add planting substrate or cultivated soil of the target thickness into the planting trough 10, sow or plant seeds onto the planting substrate or cultivated soil, and water the seeds; or, add planting substrate or cultivated soil of the target thickness into the planting trough 10, sow or plant seeds onto the planting substrate or cultivated soil, and water the seeds. After the seeds have grown stably and survived, place the planting trough 10 into the placement trough.

[0026] During the planting process, when manually excavating the placement trench in the water flow path area, the trench can be appropriately deepened and widened, and then the pre-made planting trough 10 can be placed into the placement trench.

[0027] After placing the planter into the planting trough 10, a certain amount of arable soil or planting substrate can be added to the planting trough 10. Seeds can be broadcast or sown during the planting season, followed by watering. Alternatively, the planting substrate can be pre-filled into the planting trough 10 for vegetation establishment. After the plants have established themselves stably, they can be moved to the target planting area.

[0028] The planting trough 10 is mainly used to support the planting substrate, facilitating the transplantation and survival of the target sand-fixing plants. The planting trough 10 should have good morphological plasticity and biodegradability. At the same time, the manufacturing process of the planting trough 10 should be as simple as possible, convenient for construction, and easy to obtain materials.

[0029] To meet the above requirements, this embodiment selects clay, peat moss, and crushed crop residues in an 8:1:1 ratio to prepare the planting trough 10 material. These raw materials are readily available locally and have the characteristics of being suitable for industrial production. The planting trough 10 of this invention can improve key environmental factors such as water, fertilizer, air, heat, and soil for plant growth in a localized area, exhibiting multiple ecological effects such as soil stabilization, moisture retention, and fertilizer retention. The planting trough 10 provides ideal physical and chemical properties for the growth and transplantation of target sand-fixing plants. Simultaneously, the planting trough 10 is biodegradable. After successful planting, as the plants grow and develop, their roots penetrate the planting trough 10. After the planting trough 10 is destroyed, it is biodegradable and integrates with the local soil without causing negative environmental impacts.

[0030] After the materials for the planting trough 10 are prepared, a production mold for the planting trough 10 can be set up according to the project requirements. In this embodiment, the thickness of the frame of the planting trough 10 can be designed to be 5-10cm, the width to be 50-60cm, and the length to be 80-100cm. Its size can be adjusted according to the project requirements and is not limited here.

[0031] The planting substrate within planting trough 10 can be designed artificially according to the target plant or local conditions. Both the imported soil and the planting substrate should be superior to the soil in sandy areas. The preparation of the planting substrate needs to comprehensively consider factors such as plant species, growth stage, and environmental conditions, and its preparation requirements include the following: 1) To provide the basic nutrients needed for the initial growth of plants; 2) It has good air permeability and water retention; 3) It has a certain thickness, and the sand-fixing plants are mostly deep-rooted plants; 4) Save fertilizer and water in later production management.

[0032] To meet the above requirements, this invention selects peat, humus, perlite and clay in a ratio of 5:3:1:1 to prepare a planting substrate, which has good aeration and water permeability, adjustable soil texture, and sufficient nutrient content, which is conducive to plant growth.

[0033] In this embodiment, the plant seed is a sand-fixing shrub 20, which can be Caragana korshinskii, Euphorbia pekinensis, Nitraria tangutorum, or Red Sandalwood, etc., and is not limited here.

[0034] It should be noted that the photovoltaic (PV) panel array in a photovoltaic (PV) system shapes the unique microenvironment of a PV power station by altering the spatial distribution of precipitation, intercepting and converting some solar radiation, standardizing wind direction, and reducing wind speed. Due to the structure of the PV array, solar radiation and rainfall can be largely intercepted by the PV panels, directly impacting evaporation, wind speed, air temperature, and soil temperature. During rainfall, raindrops intercepted by the PV panels concentrate along the lower edge of the panels and fall to the ground, resulting in an uneven spatial distribution of rainfall. Figure 2As shown, rainfall collects along the slope of the photovoltaic panel, reaching the lower edge of the panel and dripping onto the soil surface below, forming drip lines. A rain shadow zone forms directly beneath the panel. The rain collection function of the photovoltaic panel alters the availability of water per unit area, creating a spatial pattern of high moisture content at the drip lines and low moisture content in the rain shadow zone, along with a strip-shaped vegetation pattern below the panel. Since the drip lines serve as a water flow path for rainwater collection by the photovoltaic panel, they provide a significant water supply for successful vegetation establishment beneath the panel. Combining rainwater collection with photovoltaic panels for local ecological construction at photovoltaic power plants not only helps improve the land use structure within the power plant but also increases land use efficiency and prevents secondary wind and sand hazards within photovoltaic power plants in desert areas. This plays a crucial role in promoting and driving local ecological construction and economic development. Therefore, research on wind and sand control and ecological community construction technologies for photovoltaic bases in desert, Gobi, and arid regions is helpful in achieving carbon neutrality, ensuring the sustainable operation of photovoltaic power plants, and promoting regional ecological construction.

[0035] It is understood that the present invention provides a vegetation establishment method based on the water flow path under the photovoltaic panel in the planting trough 10. By setting up specially designed planting trough 10 in the area where rainwater collects and the water flow path under the photovoltaic panel is sufficient to plant sand-fixing shrubs 20 and other plants, the utilization rate of limited water resources in the biological sand control process of the photovoltaic base is improved, the survival rate of vegetation in the rain shadow area under the photovoltaic panel is greatly improved, the surface vegetation coverage is significantly increased, and the surface soil and water stability is increased.

[0036] This invention is a planting and vegetation technology that integrates principles such as topsoil application, direct seeding, seedling transplanting, and soil and water conservation. Because the planting trough 10 of this invention is designed based on the width and depth of the water flow path, the design of the planting trough 10 effectively increases construction convenience and adjustability.

[0037] In one embodiment, after the step of watering the plant seeds, the method may further include: Regularly check the germination rate and survival rate to determine if reseeding is necessary.

[0038] In this embodiment, by regularly checking the plant growth and reseeding according to the germination rate and survival rate, the surface vegetation coverage and surface soil and water stability are further increased.

[0039] To further improve the utilization rate of water resources, in one embodiment, after the step of adding planting substrate or tillage soil of the target thickness into the planting trough 10, the following may be included: The water-retaining agent and nutrient substrate are mixed and laid on the planting substrate or cultivated soil to the target thickness.

[0040] In this embodiment, the water-retaining agent may include superabsorbent polymers and / or absorbent cotton, etc., which are not limited here. The dosage of the water-retaining agent can be 15-25g / plant, and the dosage of the water-retaining agent mainly depends on the application environment and crop type.

[0041] Furthermore, in one embodiment, reference is made to Figure 2 The planting method may also include: sowing a nutrient substrate containing grass seeds in the non-water flow path area below the photovoltaic panel (i.e., the area other than the aforementioned target planting area 101); laying a planting material of a target thickness of water-retaining agent mixed with the nutrient substrate onto the nutrient substrate; laying topsoil onto the planting material; and applying water to the topsoil.

[0042] The non-water flow path area below the photovoltaic panel is roughly the shaded area shown in the diagram.

[0043] The nutrient substrate is designed based on the soil fertility assessment of desert and Gobi regions, and its composition and configuration can be adjusted according to the site conditions of the vegetation establishment area. Specifically, the nutrient substrate consists of a substrate with considerable fertility, mainly composed of various crop straws, biogas residues, fallen leaves and branches, and wood ash that are readily available locally and easily converted into humus. This invention does not have specific limitations on the source of the substrate; conventional sources are acceptable. Depending on the local soil texture, a certain amount of clay can be added to improve the soil texture by mixing clay with sand.

[0044] This invention mixes grass seeds with a water-retaining agent and incorporates them into a nutrient matrix, which significantly improves the survival rate of vegetation on desertified land in photovoltaic bases, thereby significantly reducing the exposed surface area, increasing surface vegetation coverage, and improving surface soil and water stability.

[0045] In this embodiment, the grass species planted in the non-water flow path area of ​​the rain shadow area can be perennial sand-fixing herbs such as ice grass, sharp grass and buffalo grass.

[0046] In this embodiment, the water-retaining agent may include superabsorbent polymer and / or absorbent cotton, etc., and is not limited thereto.

[0047] In this embodiment, the target thickness of the planting material is preferably 5-10 cm. The thickness of the planting material mainly depends on the fertility of the surface soil of the photovoltaic base, and is not limited here.

[0048] In this embodiment, the amount of water-retaining agent used in non-flow path areas can be 20-50 g / m². 2 In this embodiment, the thickness of the topsoil layer is preferably 3-5cm, but is not limited here.

[0049] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
