Technical Field

[0001] This utility model relates to the field of forestry maintenance technology, specifically a composite maintenance structure for moisturizing and preventing erosion of forest tree roots. Background Technology

[0002] In the process of forestry planting and protection, the moisture retention and erosion prevention of tree roots are among the key factors affecting the growth and survival of trees, especially in harsh environments such as drought, sandstorms, and rainstorms, where tree roots are easily damaged by water loss and soil erosion.

[0003] Traditional maintenance methods typically involve simple soil covering or watering, but these methods have limited moisture retention and are easily damaged, making it difficult to effectively solve the problems of root moisture retention and erosion prevention. Furthermore, they are prone to failure in harsh environments. Therefore, a maintenance structure that can effectively retain moisture, prevent erosion, and is structurally stable is needed to protect tree roots. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite maintenance structure for moisturizing and preventing erosion of forest tree roots, so as to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A composite maintenance structure for moisturizing and preventing erosion of forest tree roots includes an annular trench. The annular trench is opened in the soil surrounding the tree roots. The annular trench is provided with an air-permeable layer, a moisture-permeable layer, and an anti-erosion layer. The air-permeable layer is located at the bottom of the inner wall of the annular trench, the moisture-permeable layer is located at the top of the air-permeable layer, and the anti-erosion layer is located at the top of the moisture-permeable layer. A biodegradable support is arranged around the annular trench, and the biodegradable support is located outside the air-permeable layer, the moisture-permeable layer, and the anti-erosion layer.

[0007] Preferably, the breathable layer has porous and water-permeable properties and is made of coconut coir or ceramic granules, with a thickness of 5-10cm.

[0008] Preferably, the moisturizing layer is composed of a mixture of highly absorbent resin and humus in a ratio of 1:5 to 1:10, with a thickness of 10-15 cm.

[0009] Preferably, the anti-erosion layer is made of straw woven material or geotextile, and the surface is provided with a flow channel. The flow channel is a circular hole that penetrates the anti-erosion layer, with a hole diameter of 2-5cm and a spacing of 10-15cm.

[0010] Preferably, slow-release fertilizer capsules are uniformly embedded in the moisturizing layer, and the slow-release fertilizer capsules have a particle size of 1-2 cm.

[0011] Preferably, the biodegradable support is made of bamboo strips or polylactic acid plastic, with a height of 20-30cm and an insertion depth of 15-20cm into the soil.

[0012] Preferably, a plurality of U-shaped nails are provided above the anti-corrosion layer, and the anti-corrosion layer is fixed to the surface of the biodegradable bracket by the U-shaped nails, with the fixing points spaced 30-50cm apart.

[0013] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: Through a scientific layered structure and material selection, it achieves high efficiency and ecological sustainability in forestry tree root maintenance.

[0019] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0020] Please see Figure 1-4A composite maintenance structure for moisturizing and preventing erosion of forest tree roots includes an annular trench 1, which is opened in the soil around the tree roots. The annular trench 1 is provided with an air-permeable layer 2, a moisture-permeable layer 3, and an anti-erosion layer 4. The air-permeable layer 2 is located at the bottom of the inner wall of the annular trench 1, the moisture-permeable layer 3 is located at the top of the air-permeable layer 2, and the anti-erosion layer 4 is located at the top of the moisture-permeable layer 3. A biodegradable support 5 is arranged around the annular trench 1, and the biodegradable support 5 is located around the air-permeable layer 2, the moisture-permeable layer 3, and the anti-erosion layer 4.

[0021] Through the above technical solution, the annular trench 1 provides a stable space for the air-permeable layer 2, the moisture-retaining layer 3, and the anti-erosion layer 4, allowing each layer to be stacked in an orderly manner. The air-permeable layer 2 ensures good air circulation between the soil and the outside air, providing sufficient oxygen to the tree roots, which is beneficial for root respiration and promotes root growth and development. The moisture-retaining layer 3 absorbs and retains a large amount of water, providing a continuous water supply to the tree roots, effectively reducing water evaporation, prolonging the retention time of water in the soil, and maintaining a relatively humid environment around the tree roots to meet the water requirements for tree growth. The anti-erosion layer 4 can effectively prevent the erosion of the soil around the tree roots by natural factors such as rainwater erosion, protect the soil structure around the tree roots, and reduce soil erosion. The biodegradable support 5 surrounds the outer perimeter of each layer, which not only enhances the stability of the entire composite maintenance structure and prevents it from shifting under the influence of external factors, but also avoids long-term pollution of the soil environment due to its biodegradable characteristics, which is conducive to maintaining the sustainability of forestry ecology.

[0022] The breathable layer 2 has porous and water-permeable properties and is made of coconut coir or ceramic granules, with a thickness of 5-10cm;

[0023] Through the above technical solutions, the porous and permeable properties of coconut coir or ceramsite can ensure the aeration of the soil around the tree roots, allowing the roots to breathe normally. At the same time, excess water can be drained in time, preventing root rot caused by water accumulation, and creating a good soil environment for the healthy growth of trees.

[0024] The moisturizing layer 3 is composed of a mixture of highly absorbent resin and humus in a ratio of 1:5 to 1:10, with a thickness of 10-15cm.

[0025] Through the above technical solution, the superabsorbent resin in the moisturizing layer 3 can absorb and store a large amount of water, and then slowly release it to provide a continuous water supply for the tree roots. The humus can improve the soil structure and increase soil fertility. The moisturizing layer 3 formed by mixing the two in a specific ratio can significantly improve the soil's water and fertilizer retention capacity, reduce water evaporation and nutrient loss, and promote tree growth.

[0026] The anti-erosion layer 4 is made of straw woven material or geotextile, and the surface is provided with a guide groove 7. The guide groove 7 is a circular hole that penetrates the anti-erosion layer 4, with a hole diameter of 2-5cm and a spacing of 10-15cm.

[0027] Through the above technical solutions, the anti-erosion layer 4 is made of straw woven material or geotextile, which can effectively block rainwater from directly eroding the underlying moisture-retaining layer 3 and breathable layer 2, reducing soil erosion. The surface drainage channel 7 design can guide rainwater to quickly and evenly penetrate into the moisture-retaining layer 3, improve rainwater utilization, and ensure that the tree roots can fully absorb water.

[0028] Slow-release fertilizer capsules 6 are evenly embedded in the moisturizing layer 3, with a particle size of 1-2 cm.

[0029] Through the above technical solution, the slow-release fertilizer capsules 6, which are uniformly buried in the moisturizing layer 3, can slowly release nutrients over time, providing a long-term and stable supply of fertilizer for tree growth. This avoids the waste of nutrients and soil pollution caused by one-time fertilization, and the uniform burial method allows the tree roots to absorb nutrients from all directions, promoting balanced root growth.

[0030] The biodegradable support 5 is made of bamboo strips or polylactic acid plastic, with a height of 20-30cm and an insertion depth of 15-30cm into the soil.

[0031] Through the above technical solution, the biodegradable support 5 is made of bamboo strips or polylactic acid plastic, which has good strength and stability. It can firmly fix the breathable layer 2, the moisturizing layer 3 and the anti-corrosion layer 4, preventing them from shifting and deforming. At the same time, its biodegradable characteristics allow it to decompose naturally after a period of use, without causing harm to the soil and the environment.

[0032] Multiple U-shaped nails 8 are installed above the anti-corrosion layer 4. The anti-corrosion layer 4 is fixed to the surface of the biodegradable bracket 5 by the U-shaped nails 8, with a fixing point spacing of 30-50cm.

[0033] Through the above technical solution, the U-shaped nail 8 firmly fixes the anti-corrosion layer 4 to the surface of the biodegradable support 5, ensuring that the anti-corrosion layer 4 remains stable under natural conditions such as wind and rain, preventing it from being lifted or displaced, thereby better playing its anti-corrosion role and ensuring the integrity and effectiveness of the entire composite maintenance structure.

[0034] During construction, first clear away debris around the tree roots and dig a circular trench 1 20-30cm deep, ensuring no damage to the main root. Then, lay a 5-10cm thick aeration layer 2 of coconut coir or expanded clay pebbles at the bottom of the circular trench 1, compacting it to ensure water and air permeability. Next, fill the aeration layer 2 with a moisture-retaining layer 3 formed by a mixture of highly absorbent resin and humus, 10-15cm thick, compacting it appropriately as you fill to ensure the moisture-retaining layer 3 is dense. When the moisture-retaining layer 3 is about half full, evenly bury the slow-release fertilizer capsules 6 at certain intervals. Then continue filling with the remaining moisture-retaining layer 3 material. Afterward, use scissors or a knife to cut the anti-erosion layer 4 material to a suitable size, matching the shape and size of the circular trench 1 to avoid wrinkles or gaps. Then, smoothly cover the surface of the moisture-retaining layer 3, ensuring the anti-erosion layer 4 material completely covers the moisture-retaining layer 3. The edges of the anti-erosion layer 4 should extend a certain distance beyond the circular trench 1 for fixation. Finally, place the biodegradable support 5 along the circular trench 1. The edges are inserted into the soil to form a ring frame. The insertion depth of the biodegradable support 5 should ensure its stability, generally 15-30cm into the soil and 5-10cm above the ground. Then, use U-shaped nails 8 to fix the edge of the anti-erosion layer 4 to the biodegradable support 5. The fixing points are evenly distributed to ensure that the anti-erosion layer 4 will not shift due to wind or rain. After installation, the breathable layer 2 quickly drains accumulated water to prevent root rot and ensures air circulation. The moisture-retaining layer 3 collects rainwater or irrigation water and releases it slowly. Humus provides long-lasting fertility, and the slow-release fertilizer capsules 6 replenish nutrients as water penetrates. The anti-erosion layer 4 blocks rainwater from directly washing away the roots. The drainage channel 7 concentrates rainwater into the moisture-retaining layer 3 to reduce surface runoff. The biodegradable support 5 fixes the layered structure to prevent displacement. After the material degrades naturally, it integrates into the soil to avoid pollution. Through the above structure, moisture retention, breathability, anti-erosion, and fertilization are integrated, effectively solving the problems of root moisture retention and anti-erosion, improving the tree's resistance, and suitable for arid, sloping, and urban greening scenarios.
