Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, and more specifically, to a novel submerged plant planting mat. Background Technology

[0002] In recent years, eutrophication of rivers and lakes has become an increasingly serious problem. To restore the ecology of these eutrophic water bodies, aquatic plant restoration has been widely applied. Submerged plants, as an important component of aquatic systems, are entirely submerged underwater, playing a role in improving water quality and maintaining the ecological balance of aquatic ecosystems.

[0003] Currently, common methods for cultivating submerged plants include direct sowing and using planting containers. Direct sowing involves scattering plant seeds or vegetative propagules directly onto the bottom of the water body, allowing them to grow naturally. However, this method often results in uneven plant distribution, difficulty in controlling plant growth direction, and a low survival rate. While using planting containers, such as pre-planting submerged plants in them, can improve the survival rate to some extent, in high-velocity water, the containers cannot be stably fixed to the bottom, making it difficult for plant roots to penetrate and grow steadily, further impacting the survival rate of submerged plants.

[0004] A Chinese invention patent, titled "An Underwater Protection Planting Device and Method for Submerged Plant Communities Resisting Water Disturbance" with publication number CN117502026A, includes a planting substrate bed with several grooves forming submerged plant planting troughs. Each planting trough contains planting substrate, forming a plant planting mat, in which submerged plants are inserted. Multiple microporous aeration discs are positioned above the planting substrate bed, and multiple barbed posts are positioned below it. Each barbed post has multiple layers of upward-sloping barbs around its circumference to ensure the planting container is fixed to the bottom of the river. However, this invention relies on the barbed posts to fix the planting substrate bed, lacking dynamic adaptation to the plant growth stages. It provides weak direct protection for seedlings, and the fixation by the barbed posts in the later stages of plant growth restricts natural plant growth and root expansion, thus affecting plant health and survival rate. Utility Model Content

[0005] The purpose of this application is to provide a new type of submerged plant planting mat, which solves the technical problem that existing submerged plant planting mats lack dynamic adaptation to the plant growth stages during use, and provides full-cycle protection for submerged plants from the initial planting stage to maturity.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0007] This utility model provides a novel submerged plant planting mat, comprising a protective layer, a planting layer, and a fixing layer stacked sequentially from top to bottom; characterized in that: the planting layer is a biodegradable planting box, the planting box is detachably connected to the fixing layer; the planting box includes multiple upward-opening grooves, the grooves are filled with a planting substrate layer, and the bottom of the grooves is provided with multiple fixing holes;

[0008] The fixing layer is a biodegradable mesh structure woven in a cross shape. The top surface of the mesh structure has forward-leaning anchor hooks at the cross nodes, which pass through part of the fixing holes to fix the planting box. The bottom surface of the mesh structure has backward-leaning barbs at the cross nodes, which penetrate into the bottom of the river to resist the impact of water flow.

[0009] In some embodiments, the grooves are arranged in a rectangular array or a honeycomb array.

[0010] In some embodiments, the opening area at the top of the groove is larger than the area at the bottom of the groove, forming an inverted trapezoidal cross-sectional structure.

[0011] In some embodiments, the bottom sidewalls of adjacent grooves are separated to form a gap, and the gap is filled with a weight block.

[0012] In some embodiments, the weight block is a porous ceramic block.

[0013] In some embodiments, the circumferential edge of the planting box is provided with a connecting portion, and the connecting portion is provided with a through hole.

[0014] In some embodiments, the surface of the protective layer is provided with a perforation hole corresponding to the position of the groove opening.

[0015] The technical solution of this application has at least the following advantages and beneficial effects:

[0016] 1. This utility model comprises a protective layer, a planting layer, and a fixing layer stacked sequentially from top to bottom. The planting layer is a planting box, which includes multiple upward-opening grooves. These grooves enable uniform planting of submerged plants, improving planting efficiency. Furthermore, the partitioned design of the grooves avoids nutrient competition caused by the entanglement of multiple seedling roots. The fixing layer is a biodegradable mesh structure woven in a cross shape. The top surface of the mesh structure has forward-leaning anchor hooks at the intersections, which pass through some fixing holes to fix the planting box. The bottom surface of the mesh structure has backward-leaning barbs at the intersections. These barbs mechanically engage with soft bottom mud or hook onto stones, adapting to different bottom environments and improving resistance to water flow impact.

[0017] 2. This utility model provides full-cycle protection for submerged plants from the initial planting stage to maturity. In the early stage of plant growth, submerged plant seedlings are planted in the grooves of the planting box. The partitioned design of the grooves avoids nutrient competition caused by the entanglement of multiple seedling roots, and the protective layer protects the seedlings from external physical damage. In the middle stage of plant growth, the planting box gradually degrades. At this time, the plant roots pass through the fixing holes and the mesh structure in sequence, penetrate deep into the bottom of the river and take root naturally. During this period, the mesh structure provides temporary support for the plant, further improving the plant's resistance to lodging. In the later stage of plant growth, the mesh structure gradually degrades. At this time, the plant's root system has fully developed and is stably rooted in the bottom of the river, completely replacing the fixing function of the planting mat, and realizing a smooth transition from artificial assistance to natural ecology.

[0024] Example 1

[0025] Please refer to Figures 1-2 This utility model provides a novel submerged plant planting mat, which is the same as the prior art, including a protective layer, a planting layer and a fixing layer stacked from top to bottom;

[0026] The protective layer is used to prevent the loss of planting substrate due to water flow in the early stages of planting, and at the same time reduces physical damage to plant seedlings caused by external interference.

[0027] In this embodiment, the protective layer is a biodegradable non-woven fabric layer with planting holes on its surface corresponding to the groove positions; the planting holes are reserved channels for plant growth to ensure light penetration and that seedlings can successfully pass through the protective layer.

[0028] The planting layer is used to grow submerged plants.

[0029] The anchoring layer is used to secure the planting layer to the bottom of the riverbed.

[0030] Unlike existing technologies, the planting layer is a planting box 1, which is detachably connected to the fixing layer. The planting box 1 includes multiple upward-opening grooves, the inside of which is filled with a planting substrate layer, and multiple fixing holes are provided at the bottom of the grooves.

[0031] The fixing layer is a cross-woven mesh structure 2. The top surface of the mesh structure 2 has forward-leaning anchor hooks 5 at the cross nodes. The anchor hooks pass through some fixing holes to fix the planting box 1. The bottom surface of the mesh structure 2 has backward-leaning barbs 6 at the cross nodes. The barbs penetrate into the bottom of the river channel to resist the impact of water flow.

[0032] It should be noted that both the planting box 1 and the mesh structure 2 are made of biodegradable materials. During the plant growth process, the planting box 1 and the mesh structure 2 degrade sequentially, providing full-cycle protection for submerged plants from the initial planting stage to maturity.

[0033] It should be noted that in areas with rapid water flow, the riverbed is often composed of soft soil, such as silt. The backward-inclined barb 6, through its inclined design and barbed structure, can effectively penetrate the soft bottom mud and form a mechanical interlock, thereby firmly fixing the mesh structure 2 to the riverbed, resisting the impact of water flow and preventing the planting mat from shifting. In some rocky areas, the backward-inclined barb 6 can hook onto rocks or embed itself in rock crevices through its hook structure, thus ensuring the stability of the planting mat in complex bottom environments and avoiding displacement or overturning caused by water flow impact or uneven bottom.

[0034] It should be explained that the fixing holes not connected to the anchor hooks provide a channel for the seedling roots inside the planting box 1 to extend downwards; during the middle stage of plant growth, as the planting box 1 gradually degrades, the plant roots penetrate deep into the bottom of the river through the fixing holes and take root naturally, thereby achieving a smooth transition from artificial fixing to natural anchoring and further enhancing the stability of the plant under the impact of water flow.

[0035] To facilitate understanding of the working process of this utility model, the following description is provided:

[0036] like Figure 3 As shown, submerged plant seedlings are planted in the groove of planting box 1. Some fixing holes at the bottom of planting box 1 are fixedly connected to the mesh structure 2 by anchor hooks. A protective layer is laid on the top of planting box 1, which finally forms a complete planting mat. When laying, the planting mat is placed in the river channel, with the hook end facing the upstream water flow and the barb end penetrating the riverbed substrate. The mechanical interlocking and hook structure achieve double fixation to resist the impact of water flow.

[0037] In the early stages of plant growth, submerged plant seedlings are planted in the grooves of planting box 1. The partitioned design of the grooves can prevent nutrient competition caused by the entanglement of the roots of multiple seedlings.

[0038] When the plant reaches the middle stage of growth, the planting box 1 gradually degrades. At this time, the plant's roots pass through the fixing holes and the mesh structure 2 in sequence, penetrate deep into the bottom of the river and take root naturally. During this period, the mesh structure 2 provides temporary support for the plant, further improving the plant's resistance to lodging.

[0039] As the plant grows, the net structure 2 gradually degrades. At this time, the plant's root system has fully developed and is firmly rooted in the bottom of the river, completely replacing the fixing function of the planting mat and achieving a smooth transition from artificial assistance to natural ecology.

[0040] In this embodiment, the planting box 1 is made of biodegradable seedling paper with a certain degree of hardness, which can effectively protect the seedlings from damage caused by water waves; the barbs and anchor hooks are integrally formed on the mesh structure 2, which is made of biodegradable polylactic acid (PLA) material. It fixes the planting box 1 in the early stage of plant growth, provides stable support for the plant in the middle stage of plant growth, until the plant roots are fully developed and naturally replace the fixing function of the mesh structure 2.

[0041] Furthermore, the grooves are arranged in a rectangular or honeycomb array, and the regular grid structure enables uniform planting of submerged plants, thus improving planting efficiency.

[0042] Furthermore, the opening area at the top of the groove is larger than the area at the bottom of the groove, forming an inverted trapezoidal cross-sectional structure.

[0043] Furthermore, the bottom sides of adjacent grooves separate to form gaps, which are filled with weight blocks.

[0044] In this embodiment, the weight block is a porous ceramic block 4. When it comes into contact with water, it absorbs water through the pores and increases its weight, thereby increasing the vertical pressure of the planting blanket on the bottom of the river channel, thus enhancing the adhesion between the fixed layer mesh structure 2 and the bottom of the river channel. At the same time, the porous structure of the porous ceramic block 4 allows water to flow through, which reduces the lateral hydrodynamic resistance of the planting blanket and avoids lateral displacement of the planting blanket caused by the impact of water flow.

[0045] It should be explained that the ceramic material itself is non-toxic and harmless and will not have a negative impact on the aquatic ecosystem. After the planting box 1 and the mesh structure 2 degrade, the remaining porous ceramic blocks 4 can remain at the bottom of the water for a long time, which helps to enhance the submerged plants' ability to withstand the problem of falling over when the stems are too long and the water flow is too fast in the later stages of growth, and provides additional support and stability for the submerged plants.

[0046] In this embodiment, the circumferential edge of the planting box 1 is provided with a connecting part 3, and the connecting part 3 is provided with a through hole. The through hole is used to splice and fix two adjacent planting boxes 1, which increases the planting area and reduces the risk of displacement or overturning of a single planting box 1.

[0047] The specific connection method is as follows: Align the through holes on the connecting part 3 of adjacent planting boxes 1, use fasteners to pass through the two through holes in sequence and lock them to achieve a stable splicing between planting boxes 1;

[0048] It should be explained that the fasteners include, but are not limited to, ropes and hooks, wherein the ropes are made of biodegradable coconut fiber and the hooks are made of biodegradable polylactic acid (PLA) material.

[0049] It should be noted that the through-hole facilitates fixing the planting blanket in a suitable position underwater or at the water's edge.

[0050] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
