Description

Technical Field

[0001] This invention belongs to the field of rapid vegetation restoration technology, and particularly relates to a device and method for rapid vegetation restoration in karst plateau mountainous areas. Background Technology

[0002] Karst landforms are formed by the dissolution and precipitation of soluble rocks by groundwater and surface water, erosion and deposition, as well as gravity-induced collapse and deposition. They are named after the Karst Plateau in Slovenia. Due to the complex terrain and thin soil layer of the karst plateau, soil erosion is extremely severe. This makes planting vegetation on karst landforms very difficult. When planting vegetation on karst landforms, special attention must be paid to land protection and water management to prevent soil erosion and water pollution. Common soil protection measures include afforestation, grassland restoration, avoiding overgrazing and over-cultivation, and controlling wildfires. These measures can effectively prevent soil erosion and water pollution, improve the land's water retention and flood resistance, and restore and improve the ecological environment.

[0003] Vegetation restoration is a crucial step in combating rocky desertification and an effective way to improve soil quality. Soil is the material basis for plant survival and plays a vital role in vegetation restoration. In karst regions, soil erosion and loss are severe, with large areas of bedrock exposed and extensive land degradation occurring. Soil transport and loss of both surface and subsurface soil accelerate the formation of rocky desertification. Therefore, ensuring soil preservation and reducing soil loss in karst regions plays a crucial role in ecological restoration and reconstruction, providing a guarantee for improving karst soil quality and sustainable agricultural development.

[0004] In order to improve the rapid recovery of vegetation in karst plateau mountainous areas, there is an urgent need for a cheap and biodegradable device to help vegetation recover and reduce vegetation death caused by soil erosion. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus and method for rapid vegetation restoration in karst plateau mountainous areas, in order to solve the above-mentioned problems, and to achieve the goal of significantly improving the survival rate of vegetation and reducing the impact of soil erosion on plant root development while controlling costs, and at the same time, being able to degrade naturally in nature without polluting the environment.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] A device for rapid vegetation restoration in karst plateau mountainous areas includes: a compressed soil shell, an inner groove at the top of the compressed soil shell, a bottom groove at the bottom of the inner groove, the diameter of the bottom groove being smaller than the diameter of the inner groove, an inner layer of compressed soil within the inner groove, an inner layer of compressed soil slope at the top of the inner layer of compressed soil, and an inner layer of compressed soil perforation on the inner side of the inner layer of compressed soil, the height of the top of the inner layer of compressed soil perforation being lower than the height of the edge of the inner layer of compressed soil slope, the bottom groove and the inner layer of compressed soil perforation being filled with loose soil, a seed planting site being provided in the portion of the loose soil located at the inner layer of compressed soil perforation, and fungal capsules being provided at the bottom of the loose soil.

[0008] Preferably, the loose soil comprises 5 parts humus, 2 parts sawdust, and 1 part sand.

[0009] Preferably, the height of the top of the loose soil is higher than the height of the top of the perforation of the inner layer of pressed soil, and the top surface of the loose soil is higher than the perforation of the inner layer of pressed soil.

[0010] Preferably, the top of the compressed soil shell has a plurality of vertically formed perforations, and the plurality of perforations are arranged at equal intervals along the periphery of the inner groove.

[0011] A method for using a device for rapid vegetation restoration in karst plateau mountainous areas includes:

[0012] S1. Prepare the compressed soil shell;

[0013] S2. Prepare the inner layer of compressed soil and install the inner layer of compressed soil into the inner groove.

[0014] S3. The compressed soil shell is buried in an array at the location where planting is needed to form a vegetation community;

[0015] S4. The groove at the bottom end will be filled with loose soil into the perforation of the inner layer of compressed soil.

[0016] S5. Plant the plants in the loose soil;

[0017] S6. Water the inner layer of soil to moisten and loosen the soil and press down the outer layer of soil.

[0018] S7. Regularly observe the plant's development and growth, and replenish water as needed.

[0019] Preferably, the solidified mixed soil comprises 2 parts natural neutral soil, 2 parts sawdust, 2 parts fine sand, 1 part perlite powder, and 1 part clay.

[0020] Preferably, the water-absorbing mixed soil comprises 2 parts vermiculite powder, 5 parts humus, 2 parts clay, and 1 part sand.

[0021] Preferably, the fungal capsules include a decomposing paper outer layer, and the decomposing paper outer layer is filled with a dried fungal mixture soil.

[0022] Compared with the prior art, the present invention has the following advantages and technical effects:

[0023] The compressed soil shell, formed by pressing, drying, and solidifying, possesses considerable strength and is not easily dissolved. It serves as an initial protective shell, effectively preventing soil erosion and improving plant survival rates. It allows sufficient time for root development. Made from natural materials, the compressed soil shell degrades naturally in approximately 12 weeks, during which time plants can generally develop robust root systems. As the compressed soil shell degrades, the eroded soil moves downwards. The special material of the compressed soil shell slows down soil erosion, allowing plant roots to extend through it and utilize the decomposed soil for further development. This design is well-suited to the porous, water-constrained terrain of karst plateaus and mountainous areas.

[0024] In addition, an inner layer of pressed soil is set up. The inner layer of pressed soil is composed of water-absorbing natural materials, which can retain moisture well and provide initial development space for plant roots. This greatly improves the water retention effect of the device. As the water is moistened and time goes by, the inner layer of pressed soil will gradually decompose and merge with the central loose soil to form a concave soil layer, which can provide initial development conditions for plants and improve the survival rate of plants.

[0025] By utilizing these structural designs, a device and method for the rapid restoration of vegetation in karst plateau mountainous areas has been developed that can effectively improve plant survival rates, significantly reduce soil erosion rates, and can be mass-produced without polluting the environment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1: Refer to Figures 1-3 As shown, the present invention provides a device for rapid vegetation restoration in karst plateau mountainous areas, comprising: a compressed soil shell 1, an inner groove 102 at the top of the compressed soil shell 1, a bottom groove 103 at the bottom of the inner groove 102, the diameter of the bottom groove 103 being smaller than the diameter of the inner groove 102, an inner layer of compressed soil 2 within the inner groove 102, an inner layer of compressed soil slope 202 at the top of the inner layer of compressed soil 2, an inner layer of compressed soil perforation 201 on the inner side of the inner layer of compressed soil 2, the height of the top of the inner layer of compressed soil perforation 201 being lower than the height of the side of the inner layer of compressed soil slope 202, the bottom groove 103 and the inner layer of compressed soil perforation 201 being filled with loose soil 3, a seed burial site 4 being provided in the part of the loose soil 3 located in the inner layer of compressed soil perforation 201, and fungal cysts 5 being provided at the bottom of the loose soil 3.

[0036] The compressed soil outer shell 1 is a support structure that has been compressed, dried, and solidified. It possesses a certain strength and is not easily dissolved, making it suitable as an initial protective shell. This effectively prevents soil erosion, significantly improving plant survival rates and allowing sufficient time for root development. Furthermore, the compressed soil outer shell 1 is made of natural materials and degrades naturally in approximately 12 weeks, during which time plants can generally develop sufficiently strong root systems. As the compressed soil outer shell 1 degrades, the eroded soil moves downwards. Due to the special material of the compressed soil outer shell 1, the rate of soil erosion is slowed. Plant roots extend downwards through the compressed soil outer shell 1, utilizing the decomposed soil for further development. This design demonstrates excellent adaptability to the porous, water-constrained terrain of karst plateaus and mountainous areas.

[0037] In addition, an inner layer of pressed soil 2 is set up. The inner layer of pressed soil 2 is composed of water-absorbing natural materials, which can retain moisture well and provide initial development space for plant roots. It greatly improves the water retention effect of the device. As the water is moistened and time goes by, the inner layer of pressed soil 2 will gradually decompose and merge with the central loose soil 3 to form a concave soil layer, which can provide initial development conditions for plants and improve the survival rate of plants.

[0038] The solution was further optimized, with loose soil 3 consisting of 5 parts humus, 2 parts sawdust, and 1 part sand.

[0039] The scheme is further optimized so that the height of the top of the loose soil 3 is higher than the height of the top of the inner layer pressed soil perforation 201, and the top surface of the loose soil 3 is higher than the inner layer pressed soil perforation 201.

[0040] A method for using a device for rapid vegetation restoration in karst plateau mountainous areas includes:

[0041] S1. Prepare the compressed soil shell 1;

[0042] S2. Prepare inner layer compacted soil 2 and install inner layer compacted soil 2 into inner groove 102.

[0043] S3. The compressed soil shell 1 is buried in an array at the location where planting is needed to form a vegetation community. During actual installation, different spacing is determined according to the type of plant and the terrain to be restored, in order to ensure a rapid restoration effect.

[0044] S4. Fill the bottom groove 103 and the inner layer of pressed soil perforation 201 with loose soil 3. When filling with loose soil 3, avoid compaction and ensure that the bottom groove 103 is completely filled. The loose soil 3 allows plant seeds to grow well when germinating.

[0045] S5. Plant plants in loose soil 3;

[0046] S6. Water the inner layer of compacted soil 2 to moisten the loose soil 3 and the outer shell of compacted soil 1. When watering, water slowly along the slope 202 of the inner layer of compacted soil to ensure that the inner layer of compacted soil 2 is fully moistened. The water flow along the slope 202 will moisten the loose soil 3, while excess water will seep into the outer shell of compacted soil 1, preferentially moistening the bottom of the outer shell 1 and degrading it, which also meets the needs of plant root growth. When watering, be careful not to flood the soil or directly water the loose soil 3, ensuring that the loose soil 3 remains loose and aerated to prevent the plant roots from being soaked and rotting.

[0047] S7. Regularly observe the plant's development and growth, and replenish water as needed.

[0048] Further optimization of the solution, step S1 includes:

[0049] S1.1: Add the solidified mixed soil to the mixer, add an appropriate amount of water and mix thoroughly;

[0050] S1.2: The mixed soil is placed in a compressor for compaction to obtain a high-strength compacted soil shell 1;

[0051] S1.3: Dry and solidify the outer shell 1 of the compressed soil.

[0052] The solution was further optimized, and the solidified mixed soil consisted of 2 parts natural neutral soil, 2 parts sawdust, 2 parts fine sand, 1 part perlite powder, and 1 part clay.

[0053] Further optimization of the solution, step S2 includes:

[0054] S2.1: Add the water-absorbing mixed soil to the mixer, add an appropriate amount of water and mix thoroughly;

[0055] S2.2: The mixed water-absorbing soil is placed in a compressor for compaction to obtain inner layer compacted soil 2 with strong water absorption capacity;

[0056] S2.3: Make an inner layer compacted soil perforation 201 on the inner side of the inner layer compacted soil 2, and trim the periphery of the inner layer compacted soil 2 to fit the size of the inner groove 102.

[0057] S2.4: Place the inner layer of compacted soil 2 into the inner groove 102 and press the inner layer of compacted soil 2 to ensure that the inner layer of compacted soil 2 is in close contact with the outer shell 1 of the compacted soil.

[0058] The solution was further optimized, and the water-absorbing mixed soil consisted of 2 parts vermiculite powder, 5 parts humus, 2 parts clay, and 1 part sand.

[0059] Further optimizing the design, the fungal capsule 5 includes a decomposable paper outer layer, filled with a dried microbial mixture. The decomposable paper outer layer is preferably made from rapidly degradable paper folded together, while the dried microbial mixture is soil containing Bacillus subtilis. Under dry conditions, Bacillus subtilis forms spores that are preserved within the decomposable paper outer layer. When water is applied from above, these spores are soaked and regrow. Bacillus subtilis can rapidly decompose the sawdust within the compressed soil outer shell 1, helping to loosen it and allowing plant roots to penetrate the shell and enter the soil layer below.

[0060] Example 2:

[0061] Reference Figures 4-5 As shown, the only difference between this embodiment and Embodiment 1 is that:

[0062] Further optimizing the design, several permeable holes 101 are vertically formed at the top of the compacted soil shell 1, and these permeable holes 101 are arranged at equal intervals along the periphery of the inner groove 102. The presence of these permeable holes 101 can significantly increase the decomposition rate of the compacted soil shell 1. In actual use, water can be injected into the interior as needed to keep the interior of the compacted soil shell 1 moist, thereby increasing the decomposition rate and allowing it to degrade in response to plant growth.
