TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental protection, in particular to a forest desertification treatment method. BACKGROUND

[0002] Due to the continuous destruction of natural vegetation for a long time, large areas of steep slopes are cultivated, causing the surface to be exposed, and the soil in mountainous areas is thin, the bedrock is shallow, and the rainstorm scouring force is strong. After a large amount of water and soil loss, the rock gradually appears exposed, and the organic matter is lost, showing a desertification phenomenon. With the passage of time, the degree and area of desertification are also deepening and developing. Desertification directly leads to the loss of land resources. Due to the lack of vegetation in the desertification area, water conservation is not possible, and the desertification phenomenon caused by continuous loss of water and soil resources often accompanies serious drinking water difficulties for people and livestock. Not only does the desertification phenomenon worsen the conditions of agricultural production, but it also causes the ecological environment to deteriorate, the biodiversity to decrease sharply, and natural disasters to occur frequently. The increasingly deteriorating fragile ecological environment in the desertification area seriously restricts the development of the local economy and society. The population problem, survival problem, and energy problem in the desertification area have become unavoidable problems. It is urgent to speed up the prevention and control of desertification.

[0003] Desertification is one of the most difficult ecological degradation phenomena to control in the world at present, and is called "earth cancer". Desertification has become one of the most serious environmental and socio-economic problems today. At present, the treatment of desertification mainly includes afforestation, returning farmland to forest, and other measures to restore vegetation and conserve water and soil in desertification areas. However, it is difficult to effectively cover green plants on steep rock walls during the treatment of mountain forest desertification, especially the planting of plants on large stone blocks forming cliffs in mountain forests, which makes the treatment of desertification more difficult.

[0004] Therefore, how to effectively cover green plants on steep rock walls, especially how to plant plants on large stone blocks forming cliffs in mountain forests, so as to improve the treatment effect of desertification is a problem that those skilled in the art need to solve. SUMMARY

[0022] Optionally, when the planting layer is laid on the surface of the stone wall in S4, the planting layer is cut and spliced according to the topography, and the opening on the planting pocket piece is arranged upward.

[0023] By adopting the technical scheme, the planting layer is cut and spliced, which can be more suitable for the topography of the stone desertification area, so as to ensure that the planting layer fully covers the stone wall, and the opening of the planting pocket piece is arranged upward, on the one hand, rainwater can more easily enter the inside of the planting cavity through the opening, and on the other hand, the plant seeds or plant seedlings can normally grow upward.

[0024] Optionally, when the planting layer is fixed in S5, a steel nail is used to directly fix the planting layer on the stone wall, and an elastic gasket is sleeved on the head of the steel nail.

[0025] By adopting the technical scheme, the steel nail fixing method has the advantages of convenience and rapidity, and the position and number of the steel nails can be reasonably arranged according to actual needs, the elastic gasket sleeved on the head of the steel nail can prevent the head of the steel nail from damaging the planting layer, and can also increase the friction between the head of the steel nail and the planting layer, so as to ensure the reliable fixation of the steel nail on the planting layer.

[0026] Optionally, a water filtering hole is formed in the end of the planting pocket piece away from the opening, and the water filtering hole is opposite to the opening on the adjacent planting pocket piece arranged along the length direction of the water filtering hole.

[0027] By adopting the above technical scheme, the water filter hole is arranged at one end of the planting pocket away from the opening, so that the excess water in the planting cavity can be discharged during use, which can avoid the phenomenon that the roots of the planted plants are flooded, and the discharged water can also be drip filtered into the planting cavity inside another planting pocket located below, which is beneficial to ensure that each planting cavity can have appropriate amount of water to ensure plant growth.

[0028] Optionally, the water storage pool is arranged at a high place of the mountain forest, the water supply pipes are connected to the same water supplement pipe at one end thereof facing the opening, one end of the water supplement pipe away from the water supply pipe is connected to the bottom of the water storage pool, an automatic valve assembly is connected in series on the water supplement pipe, and the water supply pipes are connected to the same drain pipe at one end thereof away from the opening.

[0029] By adopting the above technical scheme, the water storage pool is arranged at a high place of the mountain forest, and the water stored in the water storage pool can enter the water supply pipe through the water supplement pipe under the action of gravity by opening the automatic valve assembly, so that the water in the water pipe can enter the planting cavity through the pipe joint, thereby achieving water supplement of the planting cavity, and ensuring that the plants planted in the planting cavity will not be affected in growth due to lack of water.

[0030] Optionally, the automatic valve assembly comprises a valve outer box, two mounting holes penetrating the side wall of the valve outer box are arranged on the valve outer box, the water supplement pipe is in sealed series communication with the valve outer box through the mounting holes, a valve inner box is in sealed sliding connection in the valve outer box, water-absorbing cotton arranged in the open air is filled in the valve inner box, an elastic member is in abutting connection between the valve outer box and the valve inner box, and a water seepage hole is arranged in the side wall of the valve inner box and in communication with the valve outer box.

[0031] By adopting the technical scheme, the water-absorbing cotton can absorb and store rainwater in the rainy season, and the water-absorbing cotton can increase the gravity of the valve inner box after absorbing the rainwater, so that the valve inner box slides downward, and the outer side wall of the valve inner box is blocked on the mounting hole, thereby preventing water flow from passing through the valve outer box. When entering dry weather, the gravity of the valve inner box is reduced after the water-absorbing cotton evaporates inside, the elastic member pushes the valve inner box to slide upward, the outer side wall of the valve inner box is away from the mounting hole, thereby allowing water flow to pass through the valve outer box. When the water flow passes through the valve outer box, a small part of the water enters the inside of the valve inner box through the water seepage hole, so that the water-absorbing cotton slowly absorbs water and increases the gravity of the valve inner box, so that the valve inner box slides downward again, and the outer side wall of the valve inner box is blocked on the mounting hole again, thereby preventing water flow from passing through the valve outer box again. This not only realizes automatic opening of the valve assembly, but also automatically closes after a certain time of automatic opening, and only needs to design the size of the water seepage hole to control the water seepage time to realize the time control of the automatic opening of the valve assembly. The design structure is simple and ingenious, and can automatically control the opening and closing of the valve assembly, which not only ensures the water needed for plant growth, but also avoids waste of water resources.

[0033] By adopting the above technical scheme, the water stored in the water storage tank can enter each planting cavity, thereby avoiding the problem that water flow directly passes through the tee joint, causing more water in the low place and less water in the high place during water supply, and effectively ensuring the uniformity of water replenishment.

[0034] In summary, the present application has at least one of the following beneficial technical effects:

[0035] 1. The present application can effectively cover green plants on steep stone walls by laying and fixing the planting layer on the surface of the stone wall and planting plants in the planting cavity on the planting layer, the influence of the slope of the stone wall on plant planting can be ignored, and plants can be planted on large stone blocks forming a cliff in a mountain forest, thereby improving the management effect of stone desertification in the mountain forest.

[0036] 2. The present application can ensure that the water stored in the water storage tank can enter the water supply pipe inside through the water replenishment pipe under the action of gravity by opening the automatic valve assembly, and the water in the water pipe can enter the planting cavity through the pipe joint, thereby realizing water replenishment for the planting cavity. This can ensure that the plants planted in the planting cavity will not be affected by water shortage.

[0037] 3. The application divides the nutrient soil into a water filtering layer, an isolation layer and a planting layer. The water filtering layer can quickly drain rainwater into the planting cavity, and a small amount of water can pass through the isolation layer into the planting layer to supply the plant growth, while the isolation layer can prevent too much water from entering the planting layer, causing the loss of nutrients in the planting layer, thereby providing a good growth environment for the plant growth.

[0038] 4. The application uses the characteristics of the weight increase of the water-absorbing cotton after absorbing water, and combines a simple and ingenious structure design, to automatically close the valve assembly during the working process. Meanwhile, the application uses the characteristics of the weight decrease of the water-absorbing cotton after the evaporation of the internal water, to automatically open the valve assembly during the working process. The automatic opening and closing of the valve assembly is achieved ingeniously, which not only ensures the supplement of water required by the plant growth, but also avoids the waste of water resources caused by excessive water supplement during the water supplement process.

[0049] The present application discloses a forest desertification control method.

[0050] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, a forest desertification control method mainly comprises the following steps:

[0051] S1, preparing a planting layer 100, the planting layer 100 comprises a composite geomembrane 101, the composite geomembrane 101 is a water-impermeable material composed of a geotextile and a geomembrane, a plurality of through holes 102 are uniformly distributed on the surface of the composite geomembrane 101, a planting pocket 103 is fixedly and sealingly connected to the surface of the composite geomembrane 101 corresponding to each through hole 102, the planting pocket 103 is in the form of a semicircular conical sheet, and a planting cavity 105 is formed between the planting pocket 103 and the composite geomembrane 101; all the planting cavities 105 are arranged with openings 104 facing the same direction, the planting layer 100 can be processed and manufactured inside the factory during preparation, and after manufacturing, the planting layer 100 can be cut into a long strip according to the commonly used specifications for easy rolling and storage.

[0052] S2, during use, only the rolled and stored planting layer 100 needs to be transported to the desertification area, the planting layer 100 is preliminarily cut according to the needs of the laying area, and the planting cavity 105 is filled with nutrient soil 300 through the opening 104.

[0053] S3, planting plants inside the nutrient soil 300; planting plants inside the nutrient soil 300 can effectively ensure the nutrients required for plant growth and help ensure the survival rate of plants.

[0054] S4, laying the planting layer 100 on the surface of the stone wall, and laying the composite geomembrane 101 connected to the surface of the planting pocket 103 outward, so that the plants planted in the planting pocket 103 can effectively perform photosynthesis under sunlight.

[0055] S5, fixing the planting layer 100, laying and fixing the planting layer 100 on the surface of the stone wall, and planting plants in the planting cavity 105 on the planting layer 100, which can ignore the influence of the slope of the stone wall on plant planting, effectively cover green plants on steep stone walls, especially on large stone blocks forming cliffs in mountain forests, and improve the management effect of stone desertification in mountain forests.

[0056] S6, watering the surface of the planting layer 100; watering can provide sufficient water for the plants, which is beneficial to ensure that the plants can grow quickly.

[0057] S7, spraying a viscous mud on the surface of the planting layer 100, which can effectively prevent the planting layer 100 from being exposed to the air, thereby reducing ultraviolet radiation and increasing the anti-aging performance of the composite geomembrane 101.

[0058] Please refer to Figure 1 , Figure 3 and Figure 4 In one embodiment of the present application, in S1, when connecting the planting pocket 103, the through hole 102 is located inside the planting cavity 105 near the opening 104, the through hole 102 is fixed and sealed with a pipe joint 106 by hot melting welding, all pipe joints 106 at the same longitudinal position are detachably and sealingly connected to the same water supply pipe 107, and the end of the water supply pipe 107 away from the opening 104 is connected to a water storage tank 201. The water storage tank 201 can be built by excavating the ground, or it can be replaced by an artificial container. The water storage tank 201 can be used to collect rainwater or spring water in the forest for future use. In the dry season, the rainwater in the water storage tank 201 can be discharged through the water supply pipe 107 to supplement the water in the planting cavity 105. On the one hand, it can reduce the erosion of the nutrient soil 300 filled in the planting cavity 105 by rainwater, and on the other hand, it can improve the utilization rate of rainwater.

[0059] Please refer to Figure 5In an embodiment of the present application, the nutrient soil 300 filled in the planting cavity 105 in S2 includes a water filtering layer 301 laid along the surface of the planting pocket 103 and the composite geomembrane 101 using coarse-grained sand, and a separation layer 302 arranged inside the water filtering layer 301, the separation layer 302 being laid along the inner surface of the water filtering layer 301 using fine-grained soil, and the inside of the separation layer 302 being provided with a soil planting layer 303, the soil planting layer 303 being filled in the center of the separation layer 302 using mixed fertilizer soil. During the filling process, the water filtering layer 301, the separation layer 302 and the soil planting layer 303 can be filled simultaneously from bottom to top in a layered filling manner, so as to avoid confusion of the layers and ensure clear layering. By dividing the nutrient soil 300 into the water filtering layer 301, the separation layer 302 and the soil planting layer 303, rainwater can be quickly drained into the inside of the planting cavity 105 by the water filtering layer 301, and a small amount of water can pass through the separation layer 302 into the inside of the soil planting layer 303 to supply the required water for plant growth, while the separation layer can also prevent excessive water from entering the inside of the soil planting layer 303, causing loss of nutrients in the inside of the soil planting layer 303, so as to provide an excellent growth environment for the growth of plants.

[0060] In an embodiment of the present application, the plants in S3 include drought-resistant and easy-to-survive plant seeds, such as centipede grass and Bermuda grass. It can be understood that in other embodiments of the present application, the plants in S3 include drought-resistant and easy-to-survive plant seedlings, such as grapevines and honeysuckle, and of course, mixed planting can also be performed, such as mixing and planting seeds of centipede grass and grapevine seedlings. By planting drought-resistant and easy-to-survive plant seeds and / or seedlings in the inside of the planting cavity 105, the survival rate of the plants can be ensured in the early stage of planting, and thus the cost of breeding and maintenance after planting can be reduced.

[0061] In a specific embodiment of the present application, when the planting layer 100 is laid on the surface of the stone wall in S4, the planting layer 100 can also be secondarily cut according to the topography and geomorphology, and the planting layer 100 can be made to fit the topography and geomorphology of the stone desertification area to fully cover the stone wall by splicing. At the same time, the opening 104 on the planting pocket 103 is arranged upward. The opening 104 on the planting pocket 103 is arranged upward, on the one hand, so that rainwater can more easily enter the inside of the planting cavity through the opening 104, and on the other hand, so as to ensure that the plant seeds or plant seedlings can grow normally upward.

[0062] Please refer to Figure 2 and Figure 3In an embodiment of the present application, the planting layer 100 is fixed in S5, the steel nails 400 are used to directly fix the planting layer 100 on the stone wall, and a nail hole is drilled on the corresponding position of the stone wall before the steel nails are inserted, so as to facilitate the insertion and fixation of the steel nails. The steel nail fixing method has the advantages of convenience and rapidity, and the positions and the number of the steel nails 400 can be reasonably arranged according to actual needs. In addition, the elastic gaskets 401 made of rubber material are sleeved on the heads of the steel nails 400. The elastic gaskets 401 sleeved on the heads of the steel nails 400 can prevent the heads of the steel nails 400 from damaging the planting layer 100, and can also increase the friction between the heads of the steel nails 400 and the planting layer 100, so as to ensure the reliable fixation of the planting layer 100 by the steel nails 400.

[0063] Please refer to Figure 3 and Figure 5 In an embodiment of the present application, the water filtering holes 108 are formed on the ends of the planting pockets 103 away from the openings 104, and the water filtering holes 108 are opposite to the openings 104 on the adjacent planting pockets 103 along the length direction. The water filtering holes 108 formed on the ends of the planting pockets 103 away from the openings 104 can drain the excess water in the planting cavities 105 during use, so that the roots of the plants are not flooded, and the drained water can also drip into the planting cavities 105 in the planting pockets 103 below, which is beneficial to ensure that each planting cavity 105 has an appropriate amount of water to ensure the growth of the plants.

[0064] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the water storage pool 201 is arranged at a high position of the mountain forest, the ends of the water supply pipes 107 towards the openings 104 are connected to the same water supplement pipe 203, the end of the water supplement pipe 203 away from the water supply pipes 107 is connected to the bottom of the water storage pool 201, the automatic valve assembly 500 is connected in series on the water supplement pipe 203, and the ends of the water supply pipes 107 away from the openings 104 are connected to the same drain pipe 202. The water storage pool and the water suction device are arranged at a high position of the mountain forest, and the water stored in the water storage pool 201 can enter the water supply pipes 107 through the water supplement pipe 203 under the action of gravity by opening the automatic valve assembly 500, so that the water in the water supply pipes 107 can enter the planting cavities 105 through the pipe joints 106, thereby achieving water supplement for the planting cavities 105. In this way, the plants planted in the planting cavities 105 can not be affected by the lack of water.

[0065] Please refer to Figure 1 and Figure 6In an embodiment of the present application, the automatic valve assembly 500 comprises a valve outer box 501, two mounting holes 502 are formed in the side wall of the valve outer box 501, the water supply pipe 203 is in sealed series communication with the valve outer box 501 through the mounting holes 502, a valve inner box 503 is in sealed sliding connection inside the valve outer box 501, the valve inner box 503 is filled with water absorbing cotton 504, a rainwater collecting bucket 507 is fixedly connected to the top of the valve inner box 503, the water absorbing cotton 504 is exposed to the air through the rainwater collecting bucket 507, and the water absorbing cotton 504 can be made of sponge, cotton or other materials with water absorbing and storing properties. The valve inner box 503 is in abutting connection with the valve outer box 501 through an elastic member 505, and a water permeation hole 506 is formed in the side wall of the valve inner box 503 and in communication with the valve outer box 501. In the rainy season, the water absorbing cotton 504 absorbs and stores rainwater, and the weight of the valve inner box 503 increases after the water absorbing cotton 504 absorbs the rainwater, so that the valve inner box 503 slides downward, and the outer side wall of the valve inner box 503 blocks the mounting holes 502, thereby preventing water flow through the valve outer box 501. When it is dry, the weight of the valve inner box 503 decreases after the water absorbing cotton 504 evaporates, so that the elastic member 505 pushes the valve inner box 503 to slide upward, and the outer side wall of the valve inner box 503 is away from the mounting holes 502, thereby allowing water flow through the valve outer box 501. When water flows through the valve outer box 501, a small amount of water enters the valve inner box 503 through the water permeation hole 506, so that the water absorbing cotton 504 slowly absorbs water and increases the weight of the valve inner box 503, and the valve inner box 503 slides downward again, and the outer side wall of the valve inner box 503 blocks the mounting holes 502 again, thereby preventing water flow through the valve outer box 501 again. In this way, the automatic valve assembly 500 can not only be automatically opened, but also be automatically closed after a certain period of time, and the size of the water permeation hole 506 can be designed to control the water permeation time, so as to control the time of automatic opening of the valve assembly 500. The design is simple and ingenious, and can automatically control the opening and closing of the valve assembly 500, which not only ensures the water needed for plant growth, but also avoids waste of water resources.

[0066] It can be understood that, in other embodiments of the present application, the water absorbing cotton 504 can be replaced by directly collecting rainwater in the valve inner box 503, and a one-way valve can be arranged in the water permeation hole 506, so that a part of water flow enters the valve inner box 503 through the one-way valve when the water pressure of the water storage tank 201 is used to drain water, thereby automatically stopping the automatic valve assembly 500. In the present embodiment, the water absorbing cotton 504 can not only reduce the process of water evaporation by using the water storage property of the water absorbing cotton 504, but also more stably and reliably guide water from the outside of the valve inner box 503 into the valve inner box 503 through the water permeation hole 506 by using the water absorbing property of the water absorbing cotton 504.

[0067] Please refer to Figure 3 and Figure 4 In one specific embodiment of the present application, a three-way joint 205 is sealingly and fixedly installed on each pipe joint 106 corresponding to the same longitudinal direction on the water supply pipe 107, the three-way joint 205 is sealingly and fixedly connected with the pipe joint 106, the three-way joint 205 is fixedly connected with a water stop plate 206 inside, and the water stop plate 206 is obliquely arranged. By fixing the water stop plate inside the three-way joint, it can be ensured that the water stored in the water storage tank can enter each planting cavity, thereby avoiding the problem that the water flow directly passes through the three-way joint, causing the water to be more in the low place and less in the high place during the water supply process, effectively ensuring the uniformity of water replenishment.

[0068] The present application is mainly aimed at the problem that it is difficult to effectively cover green plants on steep cliffs during the process of governing mountain forest desertification, especially the problem that it is difficult to plant plants on huge stone blocks forming cliffs in mountain forests.

[0069] Firstly, the planting layer 100 is made in a large quantity in the factory, then the soil is filled and planted in the planting cavity 105 on the planting layer 100, and finally the planting layer 100 is fully covered on the steep cliff in a fixed manner, so as to cover the steep cliff or even the huge stone block forming the cliff with green plants through the growth of plants to achieve the purpose of governing desertification.

[0070] At the same time, during the growth of plants, the water storage tank 201 can collect rainwater during the rainy season, and when there is no precipitation for a long time during the dry season, the water stored in the water storage tank 201 can enter the inside of the water supply pipe 107 through the water replenishment pipe 203 by automatically opening the automatic valve assembly 500, so that the water in the water supply pipe 107 can enter the inside of the planting cavity 105 through the pipe joint 106, thereby achieving water replenishment for the planting cavity 105. In this way, rainwater can be stored in the water storage tank during the rainy season, and the water in the water storage tank can be automatically discharged into the planting cavity 105 to replenish water for plants during the dry season; effectively reducing the work intensity of human intervention and maintenance during the process of desertification governance.

[0071] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
