Description

Technical Field

[0001] The present invention relates to the technical field of grassland desertification control, and more specifically, to a grassland water collection and grass planting device and a grass planting method for grassland desertification control. Background Art

[0002] Grassland desertification refers to the process in which grasslands with sandy surface environments in different climate zones are affected by factors such as wind erosion, water erosion, drought, rodent and insect pests, and improper human economic activities. For example, long-term overgrazing, unreasonable reclamation, excessive logging and collection of firewood, and over-excavation of medicinal materials have damaged natural grasslands to varying degrees, causing soil erosion, coarsening and desertification of the soil, a decrease in soil organic matter content, loss of nutrients, and a decline in grassland productivity, resulting in the degradation of grasslands in areas that were not originally desert regions.

[0003] Existing grassland desertification control devices are mostly planting troughs or planting belts. After laying planting troughs or planting belts in grassland desertification areas, vegetation is planted in the planting troughs or planting belts, and nutrients and water are supplied to the vegetation planted in the planting troughs or planting belts artificially. After the vegetation grows in the planting troughs or planting belts, it plays a role in fixing sand in the grassland desertification areas. Existing planting troughs or planting belts can only achieve the planting of vegetation in grassland desertification areas and cannot restore the soil ecosystem in grassland desertification areas. When the vegetation in the planting troughs or planting belts loses artificial nutrient and water supply, even mature vegetation is difficult to survive in grassland desertification areas. Therefore, it is necessary to restore the soil ecosystem in grassland desertification areas.

[0004] Therefore, how to restore the soil ecosystem in grassland desertification areas is an urgent problem to be solved in this technical field. Summary of the Invention

[0047] Embodiment 1:

[0048] As Figures 1-4 shown, this embodiment provides a grassland water collection and grass planting device for grassland desertification control, including:

[0049] A degradable planting trough 1, with drainage openings 11 respectively penetrating through both sides of the bottom of the degradable planting trough 1. The top of the degradable planting trough 1 is funnel-shaped. The degradable planting trough 1 is provided with a connection component 2, and the connection component 2 is used to connect multiple degradable planting troughs 1;

[0050] Two degradable mesh plates, which are detachably connected in the degradable planting trough 1. The two degradable mesh plates are used to form a compost water storage layer 12, a biological breeding layer 13, and a planting layer 14 at intervals in the degradable planting trough 1. The compost water storage layer 12 is used to fill the mixture of straw scraps, feces, and soil and store water. The biological breeding layer 13 is used to fill nutrient soil and put in earthworms cocoons. The planting layer 14 is used to backfill sand and put in grass seeds;

[0051] A water guiding mechanism 4, which is arranged in the degradable planting trough 1. The water guiding mechanism 4 is used to convey and supply the water stored in the compost water storage layer 12 to the grass seeds in the planting layer 14.

[0052] It can be understood that when treating grassland desertification, a reticular groove is excavated in the grassland desertification treatment area, and the grid length and width of the reticular groove are set based on the length of the degradable planting trough 1; a plurality of degradable planting troughs 1 are placed in the reticular groove, and adjacent degradable planting troughs 1 are connected by a connecting component 2; sandy soil is backfilled between the reticular groove and the outer wall of the degradable planting trough 1; straw scraps, feces, and soil are mixed in a ratio of 3:1:1 to obtain a compost mixture, and the compost mixture is filled to the bottom in the degradable planting trough 1 to form a compost water storage layer 12; a degradable net plate is connected in the degradable planting trough 1, then the first layer of nutrient soil is filled on the degradable net plate, earthworms cocoons are put on the first layer of nutrient soil, and the second layer of nutrient soil is filled on the first layer of nutrient soil to form a biological breeding layer 13 in the degradable planting trough 1; another degradable net plate is connected in the degradable planting trough 1, then after adjusting and assembling the water guiding mechanism 4, grass seeds are put on the water guiding mechanism 4; first layer of sandy soil 141 is backfilled on another degradable net plate, and activated carbon is filled on the first layer of sandy soil 141 to form an activated carbon layer 142, then the second layer of sandy soil 143 is backfilled on the activated carbon layer 142, and gravel is laid on the second layer of sandy soil 143 to form a sand fixation layer 144; irrigation is carried out along the sand fixation layer 144, and the water for irrigation penetrates through the sand fixation layer 144, the second layer of sandy soil 143, the activated carbon layer 142, the first layer of sandy soil 141, and the biological breeding layer 13 and then enters the compost water storage layer 12 for storage, and the drain port 11 discharges the excess water, so that there is water storage in the compost water storage layer 12; after enclosing the grassland desertification treatment area, the treatment is completed;

[0053] In the initial stage of grassland desertification control, the water stored in the compost water storage layer 12 is supplied to the grass seeds through the water guiding mechanism 4, enabling the grass seeds to germinate and take root. After the grass seeds germinate and take root, the roots enter the biological breeding layer 13, and the nutrient soil in the biological breeding layer 13 supplies nutrients to the planted grass. The water evaporation of the compost water storage layer 12 is slowed down by the sand fixation layer 144, the second layer of sandy soil 143, the activated carbon layer 142, the first layer of sandy soil 141, and the biological breeding layer 13. And a compost mixture is obtained by mixing straw scraps, feces, and soil, which has the property of adsorbing water, further slowing down water evaporation. Moreover, after the water in the compost water storage layer 12 evaporates, it enters the second layer of sandy soil 143, the activated carbon layer 142, the first layer of sandy soil 141, and the biological breeding layer 13, enhancing the humidity of the second layer of sandy soil 143, the activated carbon layer 142, the first layer of sandy soil 141, and the biological breeding layer 13. The compost water storage layer 12 provides necessary humidity and nutrients for microorganisms, facilitating the growth of microorganisms in the degradable planting trough 1. The microorganisms decompose organic substances in the degradable planting trough 1, releasing carbon dioxide, water, and minerals to form humus, thereby improving the sandy soil structure in the degradable planting trough 1 and enhancing the water and fertilizer retention capacity of the sandy soil. After the cocoon hatches in the degradable planting trough 1, the nutrient soil in the biological breeding layer 13 provides necessary water and nutrients for the young earthworms. After the young earthworms grow into earthworms, they grow and move in the compost water storage layer 12, the biological breeding layer 13, and the planting layer 14, improving the air permeability, water permeability, and water retention capacity of the sandy soil in the degradable planting trough 1, making it easier for air and water to penetrate to the roots of the planted grass, promoting the root growth of the planted grass, and enhancing the cohesion between the sandy soil particles to form fertile soil aggregate structures, and promoting the microbial activities in the degradable planting trough 1, increasing the number of beneficial microorganisms, and enhancing the stability and stress resistance of the sandy soil ecosystem; the planted grass, microorganisms, and earthworms form a cyclic symbiotic ecosystem to restore the organic matter content and nutrients of the sandy soil in the degradable planting trough 1. When it rains in the grassland desertification control area, the top of the degradable planting trough 1 arranged in a funnel shape can catch rainwater over a larger area. The sand fixation layer 144, the second layer of sandy soil 143, and the activated carbon layer 142 filter the rainwater to prevent harmful substances in the rainwater from affecting the earthworms and microorganisms in the degradable planting trough 1. After the rainwater enters the degradable planting trough 1, it is stored in the compost water storage layer 12, and the excess rainwater is discharged outside the degradable planting trough 1 through the drain port 11.

[0054] In the later stage of grassland desertification control, a stable ecosystem is formed in the degradable planting trough 1. The degradable planting trough 1 and the degradable mesh plate degrade into nutrients for the planted grass, microorganisms, and earthworms. After the roots of the planted grass, microorganisms, and earthworms lose the obstruction of the degradable planting trough 1, they spread to the sandy soil outside the degradable planting trough 1, gradually restoring the organic matter content and nutrients of the sandy soil outside the degradable planting trough 1. In this technical solution, by setting a compost water storage layer 12, a biological breeding layer 13, and a planting layer 14 in the degradable planting trough 1, a cyclic symbiotic ecosystem of the planted grass, microorganisms, and earthworms is formed. In the early stage of grassland desertification control, the organic matter content and nutrients of the sandy soil in the degradable planting trough 1 are restored. In the later stage of grassland desertification control, a stable ecosystem is formed in the degradable planting trough 1. After the degradable planting trough 1 and the degradable mesh plate degrade into nutrients, the roots of the planted grass, microorganisms, and earthworms spread to the sandy soil outside the degradable planting trough 1, gradually restoring the organic matter content and nutrients of the sandy soil outside the degradable planting trough 1, achieving the restoration of the soil ecosystem in the grassland desertification area.

[0055] As shown in the figure, reserve troughs 5 are integrally provided on both sides of the degradable planting trough 1 respectively. The drain outlet 11 is located at the bottom end of the reserve trough 5. The reserve trough 5 is used to fill with straw chips to store and reserve water. A plurality of partition plates I 15 are integrally provided in the compost water storage layer 12. The partition plates I 15 are used to form a plurality of liquid storage cavities I at intervals in the compost water storage layer 12. A plurality of partition plates II 51 are integrally provided in the reserve trough 5. The partition plates II 51 are used to form a plurality of liquid storage cavities II at intervals in the reserve trough 5.

[0056] It is understandable that the precipitation in some areas for grassland desertification control is scarce, and every rainfall is extremely precious. Therefore, reserve tanks 5 are integrally provided on both sides of the degradable planting tank 1 respectively. After rainwater penetrates into the degradable planting tank 1, the rainwater first accumulates in the compost water storage layer 12. When the water at the bottom of the compost water storage layer 12 accumulates sufficiently, it enters the reserve tank 5 through the drain port 11 for storage. Straw scraps are filled in the reserve tank 5 to facilitate the entry and exit of rainwater and slow down the evaporation of water in the reserve tank 5. The water level in the reserve tank 5 drops synchronously with the water level in the compost water storage layer 12 until the water level in the compost water storage layer 12 drops below the drain port 11 and the water stored in the reserve tank 5 is consumed completely. And by arranging the reserve tanks 5 on both sides of the degradable planting tank 1, after the degradable planting tank 1 is buried in the grassland desertification control area, it has anti-pulling performance, improving the connection stability and anti-impact performance of the degradable planting tank 1. And through a plurality of partition plates I 15, a plurality of liquid storage cavities I are formed at intervals in the compost water storage layer 12, so as to prevent the water in the compost water storage layer 12 from accumulating on one side when the degradable planting tank 1 is buried in a sloping terrain. Similarly, through a plurality of partition plates II 51, a plurality of liquid storage cavities II are formed at intervals in the reserve tank 5, so as to prevent the water in the reserve tank 5 from accumulating on one side when the degradable planting tank 1 is buried in a sloping terrain, ensuring the uniformity of water distribution and the amount of water storage.

[0057] As Figure 1 and Figure 3 shown, guiding openings I 16 are formed through both sides of the degradable planting tank 1, and the guiding openings I 16 are located at the top of the compost water storage layer 12. The guiding openings I 16 are used to guide the root direction of the planted grass in the first time period.

[0058] It is understandable that the space in the degradable planting tank 1 is limited and cannot meet the space required for the growth of the planting tank. Therefore, guiding openings I 16 are opened at the top of the compost water storage layer 12. In the early stage of grassland desertification control, the water and nutrients in the compost water storage layer 12 partially penetrate into the sandy soil outside the degradable planting tank 1 through the guiding openings I 16, creating necessary water and nutrient conditions for the root growth of the planted grass. The roots of the planted grass, microorganisms, and earthworms diffuse partially into the sandy soil outside the degradable planting tank 1 through the guiding openings I 16.

[0059] As Figure 5 shown, guiding openings II 17 are formed through both sides of the degradable planting tank 1, and the guiding openings II 17 are located in the middle of the biological breeding layer 13. A degradable membrane sheet I 6 is hermetically connected in the guiding openings II 17. The degradable membrane sheet I 6 is set as any one of a PBAT degradable membrane sheet I 6 and a PLA degradable membrane sheet I 6. The guiding openings II 17 are used to guide the root direction of the planted grass in the second time period.

[0060] It is understandable that the degradation time of the degradable planting trough 1 takes 2 to 5 years. The root system of the planted grass grows very fast. The root system of the planted grass can only be guided to diffuse locally to the sandy soil outside the degradable planting trough 1 through the guide port Ⅰ16, making it difficult for the planted grass to establish a stable root network; therefore, a guide port Ⅱ17 is opened in the middle of the biological breeding layer 13, and a degradable membrane Ⅰ6 is sealed in the guide port Ⅱ17. The degradable membrane Ⅰ6 is set to any one of the PBAT degradable membrane Ⅰ6 and the PLA degradable membrane Ⅰ6. Based on the characteristics that the degradation time of PBAT (polysuccinic acid / adipate fatty esters) and PLA (polylactic acid) is greatly shortened in a composting environment rich in microorganisms, the degradation time of the degradable membrane Ⅰ6 is based on the biological breeding layer 13. The fertility and microbial content in the biological breeding layer 13 are determined by the fertility and microbial content in the biological breeding layer 13. When the fertility in the biological breeding layer 13 is sufficient and the microbial content is high, the degradable membrane I6 degrades in a short time and then opens the guide port II17. The water and nutrients in the biological breeding layer 13 are partially infiltrated into the sandy soil outside the degradable planting trough 1 through the guide port II17, creating the necessary water and nutrient conditions for the root growth of the planted grass. When the fertility in the biological breeding layer 13 is insufficient or / and the microbial content is low, the degradation time of the degradable membrane I6 is extended, providing time for the improvement of the fertility in the biological breeding layer 13 and / or the growth of microorganisms. After the degradable membrane I6 is degraded, the roots, microorganisms and earthworms of the planted grass are locally diffused into the sandy soil outside the degradable planting trough 1 through the guide port II17.

[0061] like Figure 5 As shown, guide openings III18 are provided on both sides of the degradable planting groove 1, and the guide openings III18 are located at the bottom of the planting layer 14. Three degradable membrane sheets II7 are sealed and connected in the guide openings III18. The degradable membrane sheets II7 are configured as any one of PBAT degradable membrane sheets II7 and PLA degradable membrane sheets II7. The guide openings III18 are used to guide the root direction of the planted grass in the third time period.

[0062] It can be understood that the backfill in the planting layer 14 is the sandy soil in the grassland desertification control area. Under the action of microorganisms and earthworms, it takes a long time for the sandy soil in the planting layer 14 to restore the organic matter content and nutrients of the sandy soil. Therefore, three degradable diaphragms II 7 are hermetically connected in the guiding port III 18. The degradable diaphragms II 7 on both sides are in direct contact with the sandy soil inside and outside the degradable planting tank 1. Due to the insufficient fertility and low microbial content of the sandy soil, the degradable diaphragms II 7 on both sides take a long time to degrade, providing time for the sandy soil in the degradable planting tank 1 to restore the organic matter content and nutrients. When the degradable diaphragms II 7 on both sides have not degraded, the degradable diaphragm II 7 in the middle position does not degrade. After the degradable diaphragms II 7 on both sides degrade, the degradable diaphragm II 7 in the middle position comes into contact with the sandy soil inside and outside the degradable planting tank 1 and then begins to degrade. The degradation duration of the degradable diaphragm II 7 in the middle position is based on the restored fertility and microbial content of the sandy soil in the degradable planting tank 1, providing further time for the fertility improvement and / or microbial growth of the sandy soil in the degradable planting tank 1. After all three degradable diaphragms II 7 have degraded, the roots, microorganisms, and earthworms of the planted grass spread locally to the sandy soil outside the degradable planting tank 1 through the guiding port III 18.

[0063] Preferably, the degradable planting tank 1 includes a straw planting tank, and a polyurethane resin coating I is coated on the surface of the straw planting tank. The degradable mesh plate includes a straw mesh plate, and a polyurethane resin coating II is coated on the surface of the straw mesh plate.

[0064] It can be understood that after the straw planting tank and the straw mesh plate degrade, they can directly serve as nutrients for the planted grass, microorganisms, and earthworms, enhancing the fertility of the sandy soil. However, the degradation time of the straw planting tank and the straw mesh plate is relatively short, and it is difficult to gradually restore the organic matter content and nutrients of the sandy soil in the degradable planting tank 1 before degradation. Therefore, a polyurethane resin coating I is coated on the surface of the straw planting tank, and a polyurethane resin coating II is coated on the surface of the straw mesh plate. The waterproof performance of the straw planting tank is enhanced through the polyurethane resin coating I, and the degradation time of the straw planting tank is extended. The waterproof performance of the straw mesh plate is enhanced through the polyurethane resin coating II, and the degradation time of the straw mesh plate is extended. After the polyurethane resin coating I and the polyurethane resin coating II degrade, the straw planting tank and the straw mesh plate degrade, enhancing the fertility of the sandy soil, thereby extending the degradation time of the straw planting tank and the straw mesh plate.

[0065] As Figures 6-7 shown, the way the degradable planting tank 1 is provided with the connecting component 2 is:

[0066] An overflow port I 21 is provided at the head end of the degradable planting trough 1, an overflow port II 22 is provided at the tail end of the degradable planting trough 1, a U-shaped card slot I 23 is integrally provided at the tail end of the degradable planting trough 1, a ring-shaped card plate I 24 is integrally provided at the head end of the degradable planting trough 1, docking columns 25 are integrally provided on both sides of the tail end of the degradable planting trough 1, an overflow port III 26 is provided through the degradable planting trough 1 in the docking column 25, a U-shaped card slot II 27 is integrally provided on the docking column 25 on one side, and a ring-shaped card plate II 28 is integrally provided on the docking column 25 on the other side.

[0067] It can be understood that when multiple degradable planting troughs 1 are connected longitudinally, the ring-shaped card plate I 24 of one degradable planting trough 1 is engaged into the U-shaped card slot I 23 of another degradable planting trough 1. After the ring-shaped card plate I 24 and the U-shaped card slot I 23 are engaged, the overflow port I 21 of one degradable planting trough 1 is communicated with the overflow port II 22 of another degradable planting trough 1; when multiple degradable planting troughs 1 are connected transversely, the ring-shaped card plate I 24 of one degradable planting trough 1 is engaged into the U-shaped card slot II 27 of another degradable planting trough 1, or the U-shaped card slot I 23 of one degradable planting trough 1 is engaged with the ring-shaped card plate II 28 of another degradable planting trough 1, so that the overflow port III 26 of one degradable planting trough 1 is communicated with the overflow port I 21 or the overflow port II 22; after the overflow port I 21, the overflow port II 22, and the overflow port III 26 are communicated, the water, microorganisms, and earthworms in multiple degradable planting troughs 1 can communicate with each other, avoiding the insufficient water, microorganisms, and earthworms in individual degradable planting troughs 1, which may lead to the difficult growth or death of local planted grass.

[0068] As Figures 5-7 shown, a plurality of T-shaped guide rails 8 and a plurality of vertical guide rails 81 are integrally provided on both sides of the inner wall of the degradable planting trough 1. The vertical guide rails 81 are located above the T-shaped guide rails 8. The bottom end of the vertical guide rail 81 abuts against the end of the vertical section of the T-shaped guide rail 8. The width of the vertical section of the T-shaped guide rail 8 is greater than the width of the vertical guide rail 81. The two degradable mesh plates include a degradable mesh plate I 31 and a degradable mesh plate II 32. A plurality of limiting ports I are provided on both sides of the degradable mesh plate I 31. The limiting ports I are slidably connected to the vertical sections of the T-shaped guide rails 8. A plurality of limiting ports II are provided on both sides of the degradable mesh plate II 32. The limiting ports II are slidably connected to the vertical guide rails 81.

[0069] It is understandable that when the degradable mesh plate I 31 is connected, after multiple limiting ports I of the degradable mesh plate I 31 pass through the vertical guide rails 81, the multiple limiting ports I are slidably connected to the vertical section of the T-shaped guide rail 8. After the degradable mesh plate I 31 slides along the vertical section of the T-shaped guide rail 8 through the multiple limiting ports I, the bottom end of the degradable mesh plate I 31 abuts against the horizontal section of the T-shaped guide rail 8, and the degradable mesh plate I 31 is connected in place; when the degradable mesh plate II 32 is connected, the multiple limiting ports II of the degradable mesh plate II 32 are slidably connected to the multiple vertical guide rails 81. After the degradable mesh plate II 32 slides along the multiple vertical guide rails 81, the bottom end of the degradable mesh plate II 32 abuts against the end of the vertical section of the T-shaped guide rail 8, and the degradable mesh plate II 32 is connected in place; thus, the connection positions and connection heights of the degradable mesh plate I 31 and the degradable mesh plate II 32 are positioned.

[0070] As Figure 2 and Figure 8 shown, the water guiding mechanism 4 includes:

[0071] Multiple degradable partition cylinders 41, the degradable partition cylinders 41 are connected to the middle position inside the degradable planting trough 1, and a plurality of water inlet holes 42 are opened at the bottom of the degradable partition cylinders 41, and the inner bottom end of the degradable planting trough 1 is set as an arc bottom end;

[0072] Multiple degradable conical cylinders 43, the degradable conical cylinders 43 are connected through the degradable mesh plate, and the bottom of the degradable conical cylinders 43 is arranged inside the degradable partition cylinders 41;

[0073] Multiple cotton strips 44, the cotton strips 44 are arranged inside the degradable partition cylinders 41 and the degradable conical cylinders 43, and a placing portion 45 is integrally arranged at the top section of the cotton strips 44, and the placing portion 45 is used for placing grass seeds.

[0074] It can be understood that when the compost mixture is filled into the bottom of the degradable planting trough 1, the compost mixture is filled around the degradable cylinder 41. After the compost mixture is filled, the top end of the degradable cylinder 41 protrudes from the top end of the compost water storage layer 12. Subsequently, the degradable mesh plate I 31 is connected inside the degradable planting trough 1, and the degradable conical cylinder 43 connected to the degradable mesh plate I 31 penetrates into the degradable cylinder 41. After the biological breeding layer 13 is filled on the degradable mesh plate I 31, the top end of the degradable conical cylinder 43 connected to the degradable mesh plate I 31 protrudes from the top end of the biological breeding layer 13. Subsequently, the degradable mesh plate II 32 is connected inside the degradable planting trough 1, and the degradable conical cylinder 43 connected to the degradable mesh plate II 32 penetrates into the degradable conical cylinder 43 connected to the degradable mesh plate I 31. After the two degradable conical cylinders 43 and the degradable cylinder 41 are connected, a water delivery channel is formed. The cotton strip 44 is penetrated into the water delivery channel, and grass seeds are placed on the placement part 45. The water in the compost water storage layer 12 is transported to the grass seeds through the cotton strip 44 to ensure the water supply for the roots of the grass seeds after germination. And by setting the inner bottom end of the degradable planting trough 1 as an arc-shaped bottom end, the water in the compost water storage layer 12 accumulates towards the middle position at the bottom end and then enters the degradable cylinder 41 through a plurality of water inlet holes 42 to soak the cotton strip 44, thereby ensuring the water supply.
