Description

Technical Field

[0001] The invention belongs to the technical field of vegetation restoration, and in particular relates to matrix particles and structures for restoring slope vegetation in high-altitude areas. Background Art

[0002] The ecological environment in high-altitude areas is extremely harsh, with characteristics such as strong solar radiation, long sunshine hours, low temperature, large temperature difference between day and night, and thin air. This leads to limited environmental carrying capacity of high-altitude areas themselves. The soil layer is relatively young and weak, and it takes hundreds or even thousands of years to form weak soil and meadow layers. Once the soil layer is destroyed, it is difficult for vegetation to recover in a short period of time or the recovery effect is poor.

[0003] At present, natural restoration is mostly used for slope vegetation restoration in high-altitude areas, but the natural restoration of slope vegetation is slow and the effect is poor. It is difficult for vegetation to survive on slopes with poor soil. Some people also spray nutrient matrix on the surface of the slope to increase the nutrient content of the slope, but general matrix particles are difficult to adapt to the harsh environment of high-altitude areas and have poor resistance to freezing and thawing, which leads to the problems of short growth cycle, low wintering rate and poor vegetation recovery rate of slope vegetation. At the same time, it is also easy for the vegetation system to degenerate.

[0004] Therefore, in view of the above technical problems, it is necessary to provide matrix particles and structures for slope vegetation restoration in high-altitude areas.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The purpose of the present invention is to provide matrix particles and structures for slope vegetation restoration in high-altitude areas, which can solve the problem of poor freeze-thaw resistance of the vegetation restoration matrix.

[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0008] Matrix particles for slope vegetation restoration in high-altitude areas include matrix soil and additives. The matrix soil includes the following components by mass percentage: 40-48 parts of planting soil, 10-15 parts of vermiculite, 20-25 parts of straw, 3-6 parts of compound fertilizer, and 12-18 parts of peat; the additives include the following components: 0.1-0.8 parts of binder, 5-10 parts of bentonite and 4-8 parts of anti-transpiration agent.

[0009] In one or more embodiments of the present invention, the matrix particles include matrix soil and additives. In terms of mass percentage, the matrix soil includes the following components: 45 parts of planting soil, 12 parts of vermiculite, 22 parts of straw, 4 parts of compound fertilizer, and 16 parts of peat; the additives include the following components: 0.6 parts of binder, 7 parts of bentonite and 6 parts of anti-transpiration agent.

[0010] In one or more embodiments of the present invention, the planting soil is sandy loam, abandoned soil or abandoned farmland soil, and the straw is at least one crop straw of rice, wheat, corn, peanut, sweet potato, rapeseed and soybean.

[0011] In one or more embodiments of the present invention, the binder is one or more combinations of polyvinyl acetate, carboxymethyl cellulose, and attapulgite powder, and the anti-transpiration agent is one or a combination of potassium polyacrylate and polyacrylamide.

[0012] In one or more embodiments of the present invention, the preparation steps of the matrix particles are:

[0013] S1. Weigh planting soil, straw and binder according to mass proportions, place in a stirrer and stir at a speed of 200 r / min for 0.5 h;

[0014] S2. Add compound fertilizer, peat and bentonite into the mixer and mix at a speed of 160 r / min for another 0.5 h;

[0015] S3. Finally, add the anti-transpiration agent in a stirrer and stir evenly to obtain the matrix particles.

[0016] A structure for restoring vegetation on slopes in high altitude areas comprises the matrix particles and a water retaining layer, wherein the water retaining layer is laid on the surface of the slope, a planting piece is arranged on the water retaining layer, and the planting piece is connected to the slope through a plurality of anchor rods, a planting trough is arranged in the planting piece, a restoration layer is arranged in the planting trough, and seeds are buried in the restoration layer, wherein the seeds are one or a combination of sand-fixing grass, Tibetan sand sedge, cosmos, hairy-petaled oxtera, alpine rhododendron and juniper seeds.

[0017] In one or more embodiments of the present invention, a drainage groove is formed between a pair of the planting members to transport rainwater from the slope to prevent rainwater from impacting the planting members and ensure the firmness of the planting members;

[0018] The surface of the recovery layer is covered with a heat absorption layer. Due to the long lighting time in high-altitude areas, the heat absorption layer can absorb more heat, so that the recovery layer can be maintained at a temperature suitable for seed growth, thereby greatly improving the survival rate of the seeds and preventing the seeds from being affected by low temperatures.

[0019] In one or more embodiments of the present invention, the recovery layer is composed of matrix particles and a plurality of heat preservation mechanisms, and the plurality of heat preservation mechanisms are parallel to each other. The heat preservation mechanisms are used to keep the recovery layer warm, thereby optimizing the heat preservation effect of the recovery layer, and preventing the normal survival of seeds from being affected by the large temperature difference between day and night in high altitude areas. In addition, by setting up a plurality of parallel heat preservation mechanisms, the recovery layer can be aggregated to prevent the recovery layer from becoming loose when exposed to light for a long time, thereby greatly recovering the evaporation of water in the layer;

[0020] The heat preservation mechanism includes a hollow tube, and the hollow tube is used to contain a heat preservation liquid. The heat preservation liquid is contained in the hollow tube. The heat of the sunlight during the day will be absorbed and stored by the heat preservation liquid. Since the temperature difference between day and night is large in high altitude areas and the heat preservation liquid has a large specific heat capacity, the heat preservation liquid can release heat at night and keep the recovery layer warm, thereby optimizing the heat preservation effect of the recovery layer, preventing the seeds from being affected by low temperature, and thus ensuring the survival rate of the seeds;

[0021] In addition, the insulation liquid can also replenish moisture to the recovery layer to prevent the recovery layer from being overly dry.

[0022] In one or more embodiments of the present invention, a reinforcing tube is connected to the hollow tube, and the reinforcing tube is used to install the heat conducting rod;

[0023] A heat-conducting rod is provided in the reinforcing tube, and one end of the heat-conducting rod outside the reinforcing tube is connected to a top plate, and the top plate is made of metal. During the day, the heat from sunlight is transferred to the top plate through the heat-absorbing layer, and the top plate is then transferred to the insulation liquid through the heat-conducting rod, and the insulation liquid is used to store the heat; at night, the insulation liquid releases heat to the recovery layer through the heat-conducting rod and the top plate to optimize the insulation effect of the recovery layer.

[0024] In one or more embodiments of the present invention, the hollow tube is connected with a plurality of hydrophobic strips, which may be cotton ropes, one end of which is disposed in the thermal insulation liquid, and the top plate and the hydrophobic strips are both buried in the recovery layer. If the recovery layer is relatively dry, the thermal insulation liquid in the hollow tube will be slowly released through the hydrophobic strips to moisten the recovery layer. If the recovery layer is relatively moist, the thermal insulation liquid will not be released through the hydrophobic strips.

[0025] The hollow tube is connected with a supplementary tube, one end of which is arranged in the drainage groove. When rain falls on the slope, rainwater flows in the drainage groove, and part of the rainwater enters the hollow tube through the supplementary tube for storage, so as to supplement the insulation liquid.

[0026] A one-way valve is installed on the replenishing pipe to prevent the insulation liquid in the hollow pipe from evaporating through the replenishing pipe.

[0027] Compared with the prior art, the matrix particles and structure for restoring vegetation on slopes in high altitude areas of the present invention have high thermal insulation properties, which can further improve the freeze-thaw resistance of the matrix particles, allowing vegetation to grow stably on slopes in high altitude areas, effectively solving the problems of short growth cycle of slope vegetation, low wintering rate and poor vegetation recovery rate, thereby ensuring the restoration effect of slope vegetation in high altitude areas.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] like Figures 1 to 7 As shown, the structure for restoring vegetation on slopes in high altitude areas includes a water retaining layer 1, which is laid on the surface of the slope and is used to retain water and prevent rainwater from penetrating into the slope. Planting pieces 2 are arranged on the water retaining layer 1, and the planting pieces 2 are connected to the slope through a plurality of anchor rods 201.

[0041] A drainage groove 202 is formed between a pair of planting members 2 to transport rainwater from the slope, thereby preventing rainwater from impacting the planting members 2 and ensuring the firmness of the planting members 2.

[0042] In addition, a planting groove 203 is provided in the planting member 2, and the planting groove 203 is used to accommodate a recovery layer 204. The planting groove 203 is provided with a recovery layer 204, and the recovery layer 204 is used to provide a suitable environment for the seeds to ensure the normal growth of the seeds.

[0043] Preferably, the thickness of the recovery layer 204 is 5 cm.

[0044] Specifically, the recovery layer 204 is composed of matrix particles and a plurality of heat-insulating mechanisms 3. The matrix particles include matrix soil and additives. In terms of mass percentage, the matrix soil includes the following components: 40 parts of planting soil, 10 parts of vermiculite, 20 parts of straw, 3 parts of compound fertilizer, and 12 parts of peat; the additives include the following components: 0.1 parts of binder, 5 parts of bentonite, and 4 parts of anti-transpiration agent.

[0045] The planting soil is sandy loam, the straw is a mixture of rice, wheat and corn straw, the binder is polyvinyl acetate, and the anti-transpiration agent is potassium polyacrylate.

[0046] The preparation steps of matrix particles are:

[0047] S1. Weigh planting soil, straw and binder according to mass proportions, place in a stirrer and stir at a speed of 200 r / min for 0.5 h;

[0048] S2. Add compound fertilizer, peat and bentonite into the mixer and mix at a speed of 160 r / min for another 0.5 h;

[0049] S3. Finally, add the anti-transpiration agent in a stirrer and stir evenly to obtain the matrix particles.

[0050] In addition, seeds are buried in the recovery layer 204, and the seeds are rhododendron.

[0051] Specifically, the surface of the recovery layer 204 is covered with a heat absorption layer 205. Due to the long lighting time in high altitude areas, the heat absorption layer 205 can absorb more heat, so that the recovery layer 204 can maintain a temperature suitable for seed growth, thereby greatly improving the survival rate of the seeds and preventing the seeds from being affected by low temperatures.

[0052] Preferably, the heat absorption layer 205 is activated carbon.

[0053] like Figures 1 to 7 As shown, a plurality of heat preservation mechanisms 3 are parallel to each other, and the heat preservation mechanisms 3 are used to keep the recovery layer 204 warm, thereby optimizing the heat preservation effect of the recovery layer 204, and preventing the normal survival of seeds from being affected by the large temperature difference between day and night in high altitude areas. In addition, by setting a plurality of parallel heat preservation mechanisms 3, a lattice structure can be formed, and the recovery layer 204 can be fixed by the lattice structure, so as to prevent the recovery layer 204 from becoming loose when exposed to light for a long time, thereby greatly reducing the evaporation of water in the recovery layer 204.

[0054] Among them, the insulation mechanism 3 includes a hollow tube 301, and the hollow tube 301 is used to contain an insulation liquid 302. The hollow tube 301 contains the insulation liquid 302, and the insulation liquid 302 is water. The heat from the daytime sunlight will be absorbed and stored by the insulation liquid 302. Since the temperature difference between day and night in high-altitude areas is large, and the insulation liquid 302 has a large specific heat capacity, the insulation liquid 302 can release heat at night and insulate the recovery layer 204, thereby optimizing the insulation effect of the recovery layer 204, preventing the seeds from being affected by low temperature, and thus ensuring the survival rate of the seeds.

[0055] In addition, the heat-insulating liquid 302 can also replenish moisture to the recovery layer 204 to prevent the recovery layer 204 from being overly dry.

[0056] Specifically, the hollow tube 301 is connected with a reinforcing tube 303, and the reinforcing tube 303 is used to install a heat-conducting rod 304. The reinforcing tube 303 is provided with a heat-conducting rod 304, and one end of the heat-conducting rod 304 located outside the reinforcing tube 303 is connected with a top plate 305, and the top plate 305 is made of metal. During the day, the heat from sunlight is transferred to the top plate 305 through the heat-absorbing layer 205, and the top plate 305 is then transferred to the insulation liquid 302 through the heat-conducting rod 304, and the insulation liquid 302 is used to store heat. At night, the insulation liquid 302 releases heat to the recovery layer 204 through the heat-conducting rod 304 and the top plate 305 to optimize the insulation effect of the recovery layer 204.

[0057] like Figures 1 to 7As shown, a plurality of hydrophobic strips 306 are connected to the hollow tube 301. The hydrophobic strips 306 are made of cotton material. One end of the hydrophobic strips 306 is disposed in the thermal insulation liquid 302. The top plate 305 and the hydrophobic strips 306 are both buried in the recovery layer 204. If the recovery layer 204 is relatively dry, the thermal insulation liquid 302 in the hollow tube 301 will be slowly released through the hydrophobic strips 306 to moisten the recovery layer 204. If the recovery layer 204 is relatively moist, the thermal insulation liquid 302 will not be released through the hydrophobic strips 306.

[0058] The hollow tube 301 is connected with a supplementary tube 307, one end of which is disposed in the drain groove 202. When rain falls on the slope, rainwater flows in the drain groove 202, and part of the rainwater enters the hollow tube 301 through the supplementary tube 307 for storage, and is used to supplement the insulation liquid 302.

[0059] In addition, a check valve is installed on the replenishing pipe 307 to prevent the insulation liquid 302 in the hollow tube 301 from evaporating through the replenishing pipe 307 .

[0076] In addition, the heat-insulating liquid 302 can also replenish moisture to the recovery layer 204 to prevent the recovery layer 204 from being overly dry.

[0077] Specifically, the hollow tube 301 is connected with a reinforcing tube 303, and the reinforcing tube 303 is used to install a heat-conducting rod 304. The reinforcing tube 303 is provided with a heat-conducting rod 304, and one end of the heat-conducting rod 304 located outside the reinforcing tube 303 is connected with a top plate 305, and the top plate 305 is made of metal material, and the top plate 305 can be in contact with the heat-absorbing layer 205. During the day, the heat from sunlight is transferred to the top plate 305 through the heat-absorbing layer 205, and the top plate 305 is then transferred to the heat-insulating liquid 302 through the heat-conducting rod 304, and the heat is stored by the heat-insulating liquid 302. At night, the heat-insulating liquid 302 releases heat to the recovery layer 204 through the heat-conducting rod 304 and the top plate 305 to optimize the heat-insulating effect of the recovery layer 204.

When rain falls on the slope, rainwater flows in the drain groove 202, and part of the rainwater enters the hollow tube 301 through the supplementary tube 307 for storage, and is used to supplement the insulation liquid 302.

[0102] In addition, a check valve is installed on the replenishing pipe 307 to prevent the insulation liquid 302 in the hollow tube 301 from evaporating through the replenishing pipe 307 .

[0103] Embodiment 4

[0104] like Figures 1 to 7As shown, the structure for restoring vegetation on slopes in high altitude areas includes a water retaining layer 1, which is laid on the surface of the slope and is used to retain water and prevent rainwater from penetrating into the slope. Planting pieces 2 are arranged on the water retaining layer 1, and the planting pieces 2 are connected to the slope through a plurality of anchor rods 201.

[0105] A drainage groove 202 is formed between a pair of planting members 2 to transport rainwater from the slope, thereby preventing rainwater from impacting the planting members 2 and ensuring the firmness of the planting members 2.

[0106] In addition, a planting groove 203 is provided in the planting member 2, and the planting groove 203 is used to accommodate a recovery layer 204. The planting groove 203 is provided with a recovery layer 204, and the recovery layer 204 is used to provide a suitable environment for the seeds to ensure the normal growth of the seeds.

[0107] Preferably, the thickness of the recovery layer 204 is 5 cm.

[0108] Specifically, the recovery layer 204 is composed of matrix particles and a plurality of heat-insulating mechanisms 3. The matrix particles include matrix soil and additives. In terms of mass percentage, the matrix soil includes the following components: 46.3 parts of planting soil, 14.8 parts of vermiculite, 24 parts of straw, 5.6 parts of compound fertilizer, and 16 parts of peat; the additives include the following components: 0.75 parts of binder, 7.8 parts of bentonite, and 7 parts of anti-transpiration agent.

[0109] The planting soil is abandoned farmland soil, and the straw is a mixture of sweet potato, rapeseed and soybean crop straw.

[0110] In addition, the binder is a mixture of polyvinyl acetate, carboxymethyl cellulose and attapulgite powder, and the anti-transpiration agent is polyacrylamide.

[0111] The preparation steps of matrix particles are:

[0112] S1. Weigh planting soil, straw and binder according to mass proportions, place in a stirrer and stir at a speed of 200 r / min for 0.5 h;

[0113] S2. Add compound fertilizer, peat and bentonite into the mixer and mix at a speed of 160 r / min for another 0.5 h;

[0114] S3. Finally, add the anti-transpiration agent in a stirrer and stir evenly to obtain the matrix particles.

[0115] In addition, seeds are buried in the recovery layer 204, and the seeds are rhododendron.

[0116] Specifically, the surface of the recovery layer 204 is covered with a heat absorption layer 205. Due to the long lighting time in high altitude areas, the heat absorption layer 205 can absorb more heat, so that the recovery layer 204 can maintain a temperature suitable for seed growth, thereby greatly improving the survival rate of the seeds and preventing the seeds from being affected by low temperatures.

[0117] Preferably, the heat absorption layer 205 is activated carbon.

[0118] like Figures 1 to 7 As shown, a plurality of heat preservation mechanisms 3 are parallel to each other, and the heat preservation mechanisms 3 are used to keep the recovery layer 204 warm, thereby optimizing the heat preservation effect of the recovery layer 204, and preventing the normal survival of seeds from being affected by the large temperature difference between day and night in high altitude areas. In addition, by setting a plurality of parallel heat preservation mechanisms 3, a lattice structure can be formed, and the recovery layer 204 can be fixed by the lattice structure, so as to prevent the recovery layer 204 from becoming loose when exposed to light for a long time, thereby greatly reducing the evaporation of water in the recovery layer 204.

[0119] Among them, the insulation mechanism 3 includes a hollow tube 301, and the hollow tube 301 is used to contain an insulation liquid 302. The hollow tube 301 contains the insulation liquid 302, and the insulation liquid 302 is water. The heat from the daytime sunlight will be absorbed and stored by the insulation liquid 302. Since the temperature difference between day and night in high-altitude areas is large, and the insulation liquid 302 has a large specific heat capacity, the insulation liquid 302 can release heat at night and insulate the recovery layer 204, thereby optimizing the insulation effect of the recovery layer 204, preventing the seeds from being affected by low temperature, and thus ensuring the survival rate of the seeds.

[0120] In addition, the heat-insulating liquid 302 can also replenish moisture to the recovery layer 204 to prevent the recovery layer 204 from being overly dry.

[0121] Specifically, the hollow tube 301 is connected with a reinforcing tube 303, and the reinforcing tube 303 is used to install a heat-conducting rod 304. The reinforcing tube 303 is provided with a heat-conducting rod 304, and one end of the heat-conducting rod 304 located outside the reinforcing tube 303 is connected with a top plate 305, and the top plate 305 is made of metal material, and the top plate 305 can be in contact with the heat-absorbing layer 205. During the day, the heat from sunlight is transferred to the top plate 305 through the heat-absorbing layer 205, and the top plate 305 is then transferred to the heat-insulating liquid 302 through the heat-conducting rod 304, and the heat is stored by the heat-insulating liquid 302. At night, the heat-insulating liquid 302 releases heat to the recovery layer 204 through the heat-conducting rod 304 and the top plate 305 to optimize the heat-insulating effect of the recovery layer 204.

[0122] like Figures 1 to 7As shown, a plurality of hydrophobic strips 306 are connected to the hollow tube 301, one end of the hydrophobic strips 306 is disposed in the heat preservation liquid 302, and the top plate 305 and the hydrophobic strips 306 are both buried in the recovery layer 204. If the recovery layer 204 is relatively dry, the heat preservation liquid 302 in the hollow tube 301 will be slowly released through the hydrophobic strips 306 to moisten the recovery layer 204. If the recovery layer 204 is relatively moist, the heat preservation liquid 302 will not be released through the hydrophobic strips 306.

[0123] The hollow tube 301 is connected with a supplementary tube 307, one end of which is disposed in the drain groove 202. When rain falls on the slope, rainwater flows in the drain groove 202, and part of the rainwater enters the hollow tube 301 through the supplementary tube 307 for storage, and is used to supplement the insulation liquid 302.

[0124] In addition, a check valve is installed on the replenishing pipe 307 to prevent the insulation liquid 302 in the hollow tube 301 from evaporating through the replenishing pipe 307 .

[0131] The planting soil is sandy loam, and the straw is a mixture of wheat, corn, peanuts and soybeans.

[0132] In addition, the binder is a mixture of polyvinyl acetate and attapulgite powder, and the anti-transpiration agent is a mixture of potassium polyacrylate and polyacrylamide.

[0133] The preparation steps of matrix particles are:

[0134] S1. Weigh planting soil, straw and binder according to mass proportions, place in a stirrer and stir at a speed of 200 r / min for 0.5 h;

[0135] S2. Add compound fertilizer, peat and bentonite into the mixer and mix at a speed of 160 r / min for another 0.5 h;

[0143] Specifically, the hollow tube 301 is connected with a reinforcing tube 303, and the reinforcing tube 303 is used to install a heat-conducting rod 304. The reinforcing tube 303 is provided with a heat-conducting rod 304, and one end of the heat-conducting rod 304 located outside the reinforcing tube 303 is connected with a top plate 305, and the top plate 305 is made of metal material, and the top plate 305 can be in contact with the heat-absorbing layer 205.
