Description

Technical Field

[0001] This utility model relates to the technical field of planting bag devices, specifically a planting bag for vegetation restoration and water retention. Background Technology

[0002] In vegetation restoration projects, traditional planting bags often employ a single-bag structure, resulting in poor water retention and difficulty in supplying water to plants during periods of water scarcity. Uneven seed distribution within the bag affects the uniformity of vegetation cover. When exposed to rain, the substrate inside the planting bag is easily washed away, damaging the plant's growth environment. While existing technologies incorporate water-retaining materials into the planting bags, these agents often mix with the planting layer, leading to uneven distribution and failing to fully utilize their water-retaining properties. Furthermore, existing planting bags lack directional protective structures for seed germination, making seeds susceptible to adverse external factors and resulting in low vegetation restoration efficiency. Therefore, a novel water-retaining planting bag for vegetation restoration is urgently needed to address these problems and improve vegetation restoration effectiveness. Utility Model Content

[0026] Example 1

[0027] Combined with appendix Figure 1 To be continued Figure 4 A vegetation restoration water-retaining planting bag includes a bag body 1, a water-retaining layer 2, a seed layer, and a covering layer 4. The bag body 1 is made of biodegradable non-woven fabric and has a cylindrical structure with drainage holes 5 evenly distributed at the bottom. The water-retaining layer 2 is attached and fixed to the inner wall of the bag body 1. The seed layer is located in the central area inside the bag body 1 and contains multiple independent receiving cavities 6, which are filled with plant seeds and nutrient substrate. The covering layer 4 is located above the seed layer and has a porous and breathable structure. It is connected to the edge of the bag body 1 by heat pressing. The independent receiving cavities 6 of the seed layer are separated by diaphragms 8.

[0028] The water-retaining layer 2 is formed by mixing and pressing a water-retaining agent with plant fiber, and has a thickness of 5-10 mm. The water-retaining agent is sodium polyacrylate or starch-based composite material.

[0029] The surface of the cover layer 4 is provided with a micropore array 7, and the material of the cover layer 4 is a biodegradable plastic film, which is selected from polylactic acid or starch-based composite materials.

[0030] Example 2

[0031] A vegetation restoration water-retaining planting bag includes a bag body 1, a water-retaining layer 2, a seed layer, and a covering layer 4. The bag body 1 is made of biodegradable non-woven fabric and has a cylindrical structure with drainage holes 5 evenly distributed at the bottom. The water-retaining layer 2 is attached and fixed to the inner wall of the bag body 1. The seed layer is located in the central area inside the bag body 1 and contains multiple independent receiving cavities 6, which are filled with plant seeds and nutrient substrate. The covering layer 4 is located above the seed layer and has a porous and breathable structure. It is connected to the edge of the bag body 1 by heat pressing. The independent receiving cavities 6 of the seed layer are separated by diaphragms 8.

[0032] The water-retaining layer 2 is formed by mixing and pressing a water-retaining agent with plant fiber, and has a thickness of 5-10 mm. The water-retaining agent is sodium polyacrylate or starch-based composite material.

[0033] The covering layer 4 is made of plant fiber nonwoven fabric, which is made of wood pulp fiber, bamboo fiber or coconut shell fiber.

[0034] The working principle of this invention is as follows: The water-retaining layer 2 is made of a mixture of water-retaining agent and plant fiber, which is then pressed together. The water-retaining agent (such as sodium polyacrylate or starch-based composite material) has a strong water absorption and retention capacity, absorbing and storing a large amount of water. When the external environment is dry, it slowly releases the water, providing a continuous water supply for the plant seeds and growing plants in the seed layer, ensuring plant growth. The independent containing chambers 6 of the seed layer are filled with plant seeds and nutrient substrate, providing the nutrients needed for seed germination and early growth. The diaphragms 8 between the independent containing chambers 6 prevent interference between the seeds and substrate in each chamber, ensuring uniform seed distribution. The covering layer 4 has a porous and breathable structure, ensuring air circulation required for seed germination and plant growth while preventing rainwater from directly impacting the seed layer 3 and preventing nutrient substrate loss. The drainage holes 5 at the bottom of the bag 1 drain excess water in a timely manner, preventing the seeds and plant roots from rotting due to water accumulation.

[0035] The working process of this utility model is as follows:

[0036] 1. Preparation stage: Plant seeds and nutrient substrate are filled into each independent cavity 6 of the seed layer according to a certain ratio. Then, the covering layer 4 is connected to the edge of the bag body 1 by heat pressing, completing the assembly of the vegetation restoration water-retaining planting bag.

[0037] 2. Planting stage: Place the assembled planting bags in the area where vegetation restoration is needed.

[0038] 3. Water Management Stage: During rainfall, rainwater enters the planting bag through the micropore array 7 of the covering layer 4. Some of the water is absorbed and stored by the water-retaining layer 2, while excess water is discharged through the drainage holes 5 at the bottom of the bag body 1. During droughts, the water-retaining layer 2 slowly releases the stored water to supply water to the seeds in the seed layer and the growing plants.

[0039] 5. Seed Germination and Growth Stage: Under suitable moisture, temperature, and air conditions, the seeds within the independent seed chamber 6 of the seed layer begin to germinate. The nutrient substrate provides the seedlings with the nutrients needed for initial growth. The covering layer adopts a porous and breathable structure. Whether the material is a biodegradable plastic film or plant fiber non-woven fabric, it possesses a certain degree of toughness and permeability. As the plant grows, the pushing force generated during the seedling growth will act on the covering layer. Because the microporous array of the covering layer itself reserves a certain space for seedling growth, and the covering material will gradually be stretched and torn under the continuous pushing force of the seedling, the plant can successfully break through the covering layer and grow upwards into the external environment.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
