A portable vegetation recovery method suitable for soil and rock pile slopes

Abstract

This solution discloses a portable vegetation capsule method for vegetation restoration on rocky slopes, applicable to the field of ecological restoration engineering technology. The method includes five steps: manual slope clearing, preparation of a water-collecting and water-retaining granule-sowing mixture, excavation of planting holes, planting in the vegetation capsules, and post-planting maintenance. Water-collecting and water-retaining granules, native tree, shrub, and grass seeds, and slow-release granular fertilizer are mixed in a precise ratio, filled into biodegradable vegetation capsules, and then planted manually in the gravelly soil area of ​​the rocky slope. The water-collecting and water-retaining granules expand upon contact with water, forming a sticky fibrous covering layer, which enhances seed adhesion, resists wind and rain erosion, and continuously supplies moisture. This invention is suitable for rocky slopes with a slope of ≤30°, and has the advantages of minimal slope disturbance, convenient construction, low cost, and high vegetation survival rate, effectively achieving ecological restoration and soil and water conservation on rocky slopes.

Description

Technical Field

[0001] This invention relates to the field of ecological restoration engineering technology, and in particular to a portable vegetation capsule method for vegetation restoration suitable for soil and rock slopes. Background Technology

[0002] Mountainous areas, influenced by karst geological structures and uneven distribution of water and soil resources, experience slow soil formation rates and fragile ecosystems. Large amounts of soil and rock waste generated from urbanization and mining are haphazardly dumped on roadside slopes and in valleys, creating extensive exposed soil and rock piles. These piles have loose surface layers, making seed implantation difficult and resulting in long natural vegetation recovery cycles. Furthermore, concentrated rainfall and frequent short-duration heavy downpours in mountainous areas easily trigger secondary geological disasters such as soil erosion, landslides, and even mudslides, making ecological restoration urgently needed.

[0003] Existing vegetation restoration techniques for rocky slopes mainly involve soil covering and hydroseeding with netting. Soil covering requires a thick layer of soil, which is susceptible to erosion by rainwater, and obtaining high-quality soil is difficult. Hydroseeding with netting requires large-scale equipment, which is limited by transportation conditions in mountainous areas, and also involves high initial investment and high ongoing maintenance costs. Therefore, these technologies are difficult to widely implement in ecological restoration projects on rocky slopes in mountainous areas. Summary of the Invention

[0004] The present invention aims to provide a portable vegetation capsule method for vegetation restoration suitable for soil and rock slopes, in order to solve the problems of high construction difficulty, high maintenance cost and easy induction of soil and water loss in traditional restoration techniques.

[0005] This scheme includes a portable vegetation capsule vegetation restoration method suitable for earth and rock pile slopes, comprising the following steps: S1: Manual slope clearing: screening earth and rock pile slopes with a slope of ≤30°, and manually removing loose rocks and loose stones from the slope surface; S2: Preparation of water-collecting and water-retaining granule sowing mixture: per square meter, it includes 360g of water-collecting and water-retaining granules, 2g of slow-release compound fertilizer, and 5g of granular organic fertilizer. Plant seeds should be deep-rooted native tree, shrub, and grass seeds. All materials should be thoroughly mixed to ensure that the seeds and fertilizers are evenly dispersed around the water-collecting and water-retaining granules. S3: Planting hole excavation: In the gravelly soil area of ​​the earth-rock slope, manually excavate planting holes with a size of 10cm×10cm×10cm, and control the spacing between planting holes within 1m. S4: Planting in biodegradable planting bags: Fill the mixed materials into biodegradable planting bags, then place the planting bags into the planting hole, ensuring that the planting bags are in close contact with the surrounding gravel and soil to complete the artificial planting. S5: Post-construction maintenance: After construction, regularly observe the germination and growth of vegetation, replant in areas with low germination rates in a timely manner, and water appropriately during dry seasons to ensure the survival rate of vegetation.

[0006] Furthermore, the water-collecting and water-retaining particles are made of wood fiber, cellulose fiber, adhesives, and other additives, with a diameter of 5-20 mm and a length of 5-50 mm. Upon contact with water, these particles rapidly expand and disperse, forming a sticky fiber layer covering the slope. This layer not only secures the seeds against wind and rain erosion but also locks in moisture, providing a stable humidity environment for seed germination and root growth.

[0007] Furthermore, the plant capsules are made of natural fibers such as coconut fiber and hemp fiber, or biodegradable plastics, possessing excellent air permeability and degradation properties. The plant capsules gradually decompose in the natural environment, preventing secondary pollution, while providing a stable carrier for the initial growth of seeds.

[0008] Furthermore, the plant seeds include 5g of black locust seeds, 3g of ailanthus seeds, 5g of lespedeza seeds, 5g of mulberry seeds, 15g of tall fescue seeds, and 3g of euonymus seeds. Deep-rooted plants can enhance the soil stabilization capacity of slopes, and native plants are highly adaptable and have a high survival rate. The combination of trees, shrubs, and grasses can construct a stable slope vegetation community.

[0009] The working principle and beneficial effects of this method are as follows: This method causes minimal disturbance to the slope surface of the rockfill mound, eliminating the need for operations that easily damage the slope structure, such as thick soil covering, spraying, drilling, and netting. It can prevent the artificial substrate from being washed away by rainwater from the source, thereby reducing the risk of soil erosion and secondary disasters such as slope collapse and debris flow. At the same time, the entire construction process does not require large equipment or dedicated construction access roads and can be completed manually, making it suitable for rockfill mound scenarios in mountainous areas with inconvenient transportation and possessing extremely high construction feasibility. The water-collecting and water-retaining particles in the vegetation pots expand when they come into contact with water, forming a sticky fiber layer that can effectively fix seeds, resist wind and rain erosion, lock in water and retain moisture, and continuously supply nutrients with slow-release fertilizer, significantly improving seed germination and seedling growth conditions, and increasing vegetation germination rate and survival rate. In addition, this method makes full use of the original gravelly soil environment of the rockfill mound, eliminating the need for additional investment in obtaining high-quality soil sources and renting large machinery. The process is simple, the construction period is short, and the later maintenance cost is low, achieving a balance between soil and water conservation, ecological restoration, and engineering investment cost control.

[0012] The following detailed explanation illustrates the specific implementation methods: The basic implementation examples are as follows: Figures 1-4 As shown: A portable vegetation capsule method for vegetation restoration on soil and rock slopes includes the following steps: S1 Slope Cleaning: A 25° slope of soil and rock pile in a mountainous area was selected as the test site. Loose boulders and loose stones with a diameter greater than 20cm were removed manually. After cleaning, the flatness of the slope met the planting requirements. S2 mixture preparation: Weigh the following per square meter: 5360g water-collecting and water-retaining granules, 5g black locust seeds, 3g ailanthus seeds, 5g lespedeza seeds, 5g mulberry seeds, 15g tall fescue seeds, 3g euonymus seeds, 2g slow-release compound fertilizer, and 5g granular organic fertilizer. A mixture of seeds consisting of black locust seeds, ailanthus seeds, lespedeza seeds, purslane seeds, tall fescue seeds, and euphorbia seeds; The slow-release compound fertilizer and granular organic fertilizer are combined to form a mixed fertilizer 6; the water-collecting and water-retaining granules 5 are in the middle of the plant capsule 7, and the mixed fertilizer 6 and mixed seeds 8 are wrapped around the water-collecting and water-retaining granules 5. S3 Planting Hole 2 Excavation: In the densely distributed area of ​​gravel and soil 3 on the ground line 1 of the slope, manually excavate planting holes 2 with a size of 10cm×10cm×10cm. The spacing between planting holes 2 is set to 0.8m, and they are arranged in a quincunx pattern. S4 Planting in Planting Bag 7: Fill the mixed material into the planting bag 7 made of coconut fiber. The filling amount of each bag is 1.1 times the volume of the corresponding planting hole 2. Place the planting bag 7 into the planting hole 2, backfill with gravel soil 3 and gently compact it to ensure that the planting bag 7 is firmly fixed. D5 Post-planting care: After planting, observe the germination of vegetation weekly. Seeds begin to germinate on the 10th day after planting, and the germination rate reaches 85% on the 30th day. Spray seedlings with water during dry periods and check slope drainage in a timely manner during the rainy season. By the 6th month after planting, the vegetation coverage on the slope reaches 70%, demonstrating significant soil and water conservation effects.
