[0013] The second technical solution provided by the present invention is:

[0014] A greening method for the periphery of a photovoltaic power station is applied to the ecosystem around the photovoltaic power station in the first technical solution, comprising obtaining pre-greening measurement data of a target greening area, conducting greening analysis, and determining the initial component ratio of hydrochar, the initial bacterial count of microorganisms, and the initial irrigation water quality; preparing a matrix filler according to the initial component ratio of the hydrochar, and conducting initial greening of the target greening area in combination with the initial bacterial count of microorganisms and the initial irrigation water quality; obtaining hydrochar measurement data during the greening cycle and adjusting the initial component ratio of the hydrochar; establishing potted plant samples to obtain crop growth data during the greening cycle, and adjusting the initial bacterial count of microorganisms in combination with the crop growth data during the greening cycle; and collecting effluent water quality data during the greening cycle and adjusting the initial irrigation water quality in combination with the effluent water quality data during the greening cycle.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0032] The technical solution in this application will be described below with reference to the accompanying drawings.

[0033] Please refer to Figures 1 to 3 The embodiment of the present application provides an ecosystem for the vicinity of a photovoltaic power station, which includes a hydrocharcoal wetland pool 01, a photovoltaic panel group 02, a water supply inlet pipe 03 and a fertilizer regulating pool 04; the hydrocharcoal wetland pool 01 is arranged around the photovoltaic panel group 02, and a green belt 05 is formed between the hydrocharcoal wetland pool 01 and the photovoltaic panel group 02; the water supply inlet pipe 03 is laid on the hydrocharcoal wetland pool 01, and a water supply port is opened on the water supply inlet pipe 03; the water inlet end of the water supply inlet pipe 03 passes through the fertilizer regulating pool 04 and is connected to the fertilizer regulating pool 04; the hydrocharcoal wetland pool 01 is filled with a matrix filler 13; green crops are planted on the surface of the matrix filler 13; the matrix filler 13 is supplemented with fertilizer, water and microbial agents through the water supply inlet pipe 03.

[0034] It is understandable that in order to establish a good ecological environment around the photovoltaic power station, on the one hand, a wetland pool that can effectively improve the soil environment is arranged. The wetland pool here is mainly filled with hydrothermal carbon matrix filler 13 formed based on hydrothermal treatment. The hydrothermal carbon matrix filler 13 can form hydrothermal carbon-based biofertilizer under the supplementation of water and microbial agents through the water inlet pipe 03, thereby improving the fertility of the soil and effectively changing the soil environment. Moreover, according to reasonable fertilizer supplementation, the needs of greening and crop planting in the soil can be fully met. It should be noted here that in order to further reduce the cost of improving the soil environment, livestock manure and straw are used for hydrothermal treatment, which is enough to make reasonable resource utilization of agricultural solid waste. Of course, when considering agricultural production planning around the photovoltaic power station in the future, the solid waste generated by agricultural production can be further utilized as a resource, achieving a certain economic cycle effect, and also realizing the environmental protection effect of agricultural production. In this solution, the matrix filler 13 is a mixture of hydrochar and raw soil, so the matrix filler 13 includes hydrochar and raw soil, and the volume ratio of the hydrochar to the raw soil is in the range of 1:8 to 1:2.

[0035] On the other hand, by creatively designing the structure of the hydrocharcoal wetland pool 01, it is ensured that the hydrocharcoal-based biofertilizer in the hydrocharcoal wetland pool 01 can flow into the surrounding soil, thereby achieving the improvement and treatment of a larger area of ​​soil. There can be many structures for the hydrocharcoal wetland pool 01, and any structure that can ensure that the hydrocharcoal-based biofertilizer can be diffused outside the wetland is desirable. In this solution, the hydrocharcoal wetland pool 01 includes a pool wall 11 and a pool bottom 12; the pool wall 11 is arranged around the edge of the pool bottom 12 to form a wetland pool trough; the distance between the end of the pool wall 11 away from the pool bottom 12 and the pool bottom 12 is greater than the distance between the ground and the pool bottom 12; an inclined hole is provided on the pool wall 11, and the distance between the end of the inclined hole close to the wetland pool trough and the pool bottom 12 is less than the distance between the end of the inclined hole away from the wetland pool trough and the pool bottom 12; the wetland pool trough is filled with matrix filler 13; and the water supply inlet pipe 03 is laid on the matrix filler 13.

[0036] The dimensions of the hydrocharcoal wetland pool 01 can be customized. The pool's structural materials can be non-degradable, such as plastic, PVC, or polymer composite fiber materials, to ensure its stability. The pool's walls 11 should be elevated above the ground to prevent irrigation water and other materials from flowing outside the wetland when the matrix filler 13 is irrigated, wasting irrigation space.

[0037] The angle between the axis of the inclined hole and the horizontal plane is 45 to 65 degrees. Such an angle can ensure that the matrix filler 13 is fully mixed with water to form hydrothermal carbon-based biofertilizer before flowing out of the wetland pool.

[0038] In addition, it should be noted that there are various ways to set up the hydrothermal charcoal wetland pool 01 around the photovoltaic power station, and the design can be carried out according to the terrain conditions, design requirements, etc. This solution provides the following three specific implementation methods to demonstrate different hydrothermal charcoal wetland pool 01 settings and related design parameters:

[0039] Example 1:

[0040] The hydrocharcoal wetland pool 01 forms a ring around the photovoltaic panel group 02. The ring shape is various, and the ring in this embodiment is rectangular. The width of the interval green belt 05 formed from the pool wall 11 on the side of the hydrocharcoal wetland pool 01 close to the photovoltaic panel group 02 to the edge of the photovoltaic panel is 20m. The water inlet pipe laid on the hydrocharcoal wetland pool 01 has a distance of 30cm between its water inlets. Here, the angle of the inclined hole on the pool wall 11 of the hydrocharcoal wetland pool 01 is 45 degrees, the pool wall 11 is 10cm above the ground, the height of the pool wall 11 is 50cm, the width of the relatively set pool wall 11 is 100cm, and the thickness of the pool bottom 12 is 2cm. The volume ratio of hydrocharcoal and original soil in the matrix filler 13 is 1:2.

[0041] Example 2:

[0042] The hydrocharcoal wetland pool 01 forms a ring around the photovoltaic panel group 02. The ring shape is various, and the ring in this embodiment is rectangular. The width of the interval green belt 05 formed from the pool wall 11 on the side of the hydrocharcoal wetland pool 01 close to the photovoltaic panel group 02 to the edge of the photovoltaic panel is 25m. The water inlet pipe laid on the hydrocharcoal wetland pool 01 has a distance of 100cm between its water inlets. Here, the angle of the inclined hole on the pool wall 11 of the hydrocharcoal wetland pool 01 is 65 degrees, the pool wall 11 is 20cm above the ground, the height of the pool wall 11 is 80cm, the width of the relatively set pool wall 11 is 300cm, and the thickness of the pool bottom 12 is 3cm. The volume ratio of hydrocharcoal and original soil in the matrix filler 13 is 1:5.

[0043] Example 3:

[0044] Multiple hydrocharcoal wetland pools 01 are spaced around the photovoltaic panel cluster 02. A water supply inlet pipe 03 is installed around the photovoltaic panel cluster 02, passing through each hydrocharcoal wetland pool 01. A water supply port is provided on the water supply inlet pipe 03 located in each hydrocharcoal wetland pool 01. In this embodiment, there are seven hydrocharcoal wetland pools 01, evenly spaced around the photovoltaic panel cluster 02. The width of the green belt 05 formed by the pool wall 11 on the side of the hydrocharcoal wetland pool 01 near the photovoltaic panel cluster 02 and the edge of the photovoltaic panel is 30 meters. The water supply pipes installed in the hydrocharcoal wetland pools 01 have a spacing of 50 cm between their inlets. The angle of the inclined holes in the pool wall 11 of the hydrocharcoal wetland pool 01 is 55 degrees. The pool wall 11 is 15 cm above the ground and 65 cm high. The width of the opposing pool walls 11 is 200 cm, and the pool bottom 12 is 2.5 cm thick. The volume ratio of hydrothermal charcoal to raw soil in the matrix filler 13 is 1:8.

[0045] An embodiment of the present invention further provides a method for greening the periphery of a photovoltaic power station. The method is applied to the ecosystem surrounding the photovoltaic power station described in this embodiment, and includes the following steps:

[0046] S1: Obtain pre-greening test data of the target greening area and conduct greening analysis to determine the initial component ratio of hydrochar, initial microbial count, and initial irrigation water quality.

[0047] First, the target greening area is measured before greening to obtain the pre-greening measurement data, and the initial component ratio of hydrothermal charcoal, initial microbial count and initial irrigation water quality for the first greening are determined based on the pre-greening measurement data.

[0048] S2: Prepare matrix filler according to the initial component ratio of hydrothermal charcoal, and carry out initial greening of the target greening area in combination with the initial bacterial count of microorganisms and the initial irrigation water quality.

[0049] This step primarily involves initial greening of the target greening area based on the initial greening data. This involves preparing a matrix filler at the initial hydrocharcoal cost ratio. Microbial strains are then added to the matrix filler based on the initial microbial count. Irrigation of the target greening area is also performed based on the initial irrigation water quality.

[0050] It should be noted that for hydrochar, the ratio is determined primarily based on factors such as soil texture, soil testing formula, crop water and fertilizer requirements, geographic location, and climate. For example, for severely drought-prone, saline-alkali land, a volume ratio of straw: cattle and sheep manure: hydroxygraphene is 40:45:15; for deserts with high winds and sand but low salinity, a volume ratio of 35:55:10 is used; for areas with moderate drought, a volume ratio of 50:40:10 is used; for areas with good soil texture and fertility, a volume ratio of 60:35:5 is used; and for areas or time periods with heavy rainfall, a volume ratio of 50:45:5 is used. In this embodiment, the initial composition ratio of the hydrochar includes straw, livestock and poultry manure, and hydroxygraphene; the straw is the straw of plants that are adapted to the target greening area. In addition, in this embodiment, the hydrothermal charcoal contains a mixture of 5-8% (35-60% of which is straw of local pasture or adaptive plants and 35-55% of cattle, sheep and poultry manure) mixed carbon source and 5-15% hydroxyl (or carboxyl) graphene particles, which is processed into hydrothermal charcoal by a hydrothermal reaction at 500-600°C.

[0051] S3: Obtain the hydrothermal charcoal measurement data during the greening period and adjust the initial composition ratio of the hydrothermal charcoal.

[0052] In periodic greening, changes in environmental conditions such as rainfall will affect the changes in the proportion of water, heat and carbon. Therefore, periodic data measurement can adjust the proportion of water, heat and carbon in time to achieve the best greening effect.

[0053] S4: Establish potted samples to obtain crop growth data during the greening cycle, and adjust the initial microbial bacterial count based on the crop growth data during the greening cycle.

[0054] This step specifically includes: establishing potted samples based on substrate fillers, initial microbial counts, and initial irrigation water quality; harvesting crops in the potted samples at greening cycle points and obtaining periodic crop growth data for the harvested crops; and adjusting the initial microbial count based on the crop growth data and in combination with the initial irrigation water quality.

[0055] This embodiment provides a specific implementation method for adjusting the initial microbial count using potted plant samples:

[0056] The strains used were arbuscular mycorrhizal fungi of alfalfa and Leymus chinensis. During each seeding period, a nutrient solution containing 1.0 to 2.5 mg / kg of plant arbuscular mycorrhizal fungi was applied to the soil (with the nutrient solution comprising 2.5 to 4.5% of the total nutrient solution). Similarly, the amount of strain applied will vary depending on the greening status of the target area, requiring adaptive adjustment. This study used potted plant samples, measuring 30 to 50 cm in diameter and 20 to 30 cm in height. Each pot was filled with 2.2 to 2.5 kg of matrix filler, and the lower water outlet was blocked with window screen. Seeding rates for alfalfa and Leymus chinensis were 35 to 42 g / m² and 40 to 43 g / m², respectively. Three replicates were placed randomly in a greenhouse, maintained at a temperature of 18 to 32°C, and watered with deionized water at appropriate times. Alfalfa and chinensis were harvested at 88 and 76 days of growth, respectively. The harvested plants were washed with clean and deionized water, respectively. They were then dried at 110-130°C for 1-2 hours and then dried at 90-100°C to a constant weight. The dry weight was measured to determine growth. The initial microbial count was adjusted based on growth and the quality of the irrigation water.

[0057] S5: Collect the effluent water quality data during the greening period, and adjust the initial irrigation water quality based on the effluent water quality data during the greening period.

[0058] This step specifically includes: setting an irrigation water quality threshold, and comparing the greening cycle water quality value with the irrigation water quality threshold: if the greening cycle water quality value is not greater than the irrigation water quality threshold, then the irrigation water quality remains unchanged; if the greening cycle water quality value is greater than the irrigation water quality threshold, then the greening cycle water quality value is reduced.

[0059] In this embodiment, the irrigation water quality threshold is set to COD 15 mg / L. When the water quality value of the greening period water quality is greater than the irrigation water quality threshold, the water quality value of the greening period water quality is generally controlled at 50-100 mg / L.

[0060] In summary, the embodiments provided by the present invention have the following main effective effects:

[0061] The ecosystem surrounding the photovoltaic power station utilizes hydrothermal charcoal wetland ponds 01, utilizing hydrothermal technology to recycle agricultural solid waste, saving environmental management costs. This process also creates hydrothermal charcoal-based biofertilizer that improves soil fertility and provides a strong foundation for greening the area around the photovoltaic power station, achieving enhanced greening results. Furthermore, the hydrothermal charcoal-based biofertilizer can be absorbed into the surrounding soil, providing a powerful foundation for rational agricultural production and living planning around the photovoltaic power station, achieving long-term governance and environmental improvement.

[0062] The greening method for the periphery of a photovoltaic power station sets initial greening data through data measurement before greening, periodically collects and analyzes greening data in the process of greening, and timely and targeted adjusts the greening scheme, so as to realize more effective and efficient greening management and environmental improvement effect.

[0063] The technical features of the above embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0064] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
