Description

Technical Field

[0001] This utility model relates to the field of container seedling technology, specifically to a water-storage seedling container for vegetation ecological restoration. Background Technology

[0002] In river and lake banks, reservoir drawdown zones, wetlands, water-land transition zones, artificial wetlands, ecological slope protection, and vegetation restoration projects, it is often necessary to pre-cultivate emergent plants, wetland plants, herbaceous slope protection plants, shrubs and grasses, or other ecological restoration plants to improve the survival rate after transplanting and the ecological restoration effect. After transplanting, ecological restoration plants typically need to adapt to complex environments such as water level fluctuations, bank erosion, poor substrate, and alternating wet and dry conditions. Therefore, developing a well-developed, downward-extending root system during the seedling stage is crucial for improving the plant's resistance to erosion, drought resistance, and planting stability.

[0003] Currently, the cultivation of seedlings for ecological restoration plants typically uses ordinary plastic seedling pots, seedling bags, plug trays, turnover pots, or ordinary flower pots. While these containers can meet the needs of conventional seedling cultivation, they still have certain shortcomings in practical application. For example, the side walls of ordinary seedling pots or flower pots are mostly smooth, allowing plant roots to easily coil horizontally along the pot walls during growth, forming root entanglement and hindering the vertical downward extension of the roots. This can lead to problems such as slow seedling establishment, shallow rooting, and insufficient resistance to lodging after transplanting.

[0004] Meanwhile, existing seedling containers typically only have drainage holes at the bottom, and the side walls have poor air permeability, making it easy for water to accumulate inside the container after watering, leading to root suffocation or insufficient aeration. Although some existing root control pots or air-guided root pruning pots have through holes, protrusions, or root-guiding structures on the side walls, which can improve root growth to some extent, these containers are mostly integral injection-molded structures with varying sizes, taking up a lot of space during transportation and storage. They are also inconvenient for flat-pack transportation and stacking during large-scale ecological restoration seedling cultivation and on-site transfer in engineering projects.

[0005] Furthermore, ecological restoration seedling cultivation and plant research experiments often require zoned cultivation based on different plant species, substrate conditions, water conditions, experimental treatment groups, engineering areas, or batches. Existing conventional seedling containers have fixed specifications and inflexible assembly methods; multiple containers typically can only be placed side-by-side, resulting in poor overall integrity and making unified handling, numbering, identification, and management inconvenient. If a container is partially damaged or ages, it usually needs to be replaced entirely, increasing usage costs.

[0006] In research on plant ecology, root architecture, seedling regulation, and vegetation ecological restoration technologies, parallel and control experiments are typically conducted for different plant species, substrate conditions, water supply conditions, root control methods, or culture batches. Scientific experiments require standardized culture units, easily identifiable and recordable treatment conditions, and the ability to remove the root ball as completely as possible after the experiment to observe root extension, lateral root branching, root coiling, and root distribution. Existing common seedling pots often lack standardized modular structures, experimental group identification structures, and bottom water level control structures. Furthermore, root damage is easily caused during disassembly and root removal, making them unsuitable for the needs of ecological restoration plant seedling research and root control experiments.

[0007] On the other hand, plant roots exhibit hydrotropism. During seedling cultivation, if a suitable amount of water can be retained at the bottom of the container, a moist root-inducing zone can be formed at the bottom of the container, guiding the roots to grow downwards. However, existing root-control pots or aeration pots often have many holes in the bottom and side walls to improve drainage and aeration performance. After watering, water is quickly lost, making it difficult to form a stable, small amount of residual water layer at the bottom. If ordinary trays are used separately, there are often problems such as unstable fit, easy misalignment, inconsistent appearance, and inconvenience in combined use. Utility Model Content

[0008] To address the problems of existing seedling containers for ecological restoration and scientific research, such as root entanglement, insufficient downward root formation, slow root establishment after transplanting, poor sidewall aeration, inconvenient transportation and storage due to their integral structure, inflexible size combinations, difficulty in replacement after partial damage, difficulty in group identification in scientific research experiments, easy damage to the root system when removing roots from pots, and difficulty in retaining an appropriate amount of root-inducing moisture at the bottom, this utility model provides a water-storage seedling container for ecological restoration. This container has advantages such as simple structure, easy assembly and disassembly, convenient flat-pack transportation and storage, suitability for mass seedling production, promotion of downward root growth, ability to induce branching roots through air pruning, bottom water storage for root induction, and ease of use for scientific research control experiments and zone identification and management.

[0009] A water-storage seedling container for vegetation ecological restoration includes a base plate with multiple drainage and ventilation holes that are open at both ends. A seedling area is located above the base plate, and a water storage area is located below the base plate. The seedling area includes multiple side plates that are inserted end to end, forming a polygonal space. The lower ends of the side plates are inserted into the upper surface of the base plate. The water storage area includes an overflow tray inserted below the base plate. A water storage tray is fitted around the overflow tray, and an overflow port communicating with the water storage tray is provided on the side of the overflow tray.

[0010] If too much water is poured into the container, the excess water can flow into the overflow tray through the drainage and ventilation holes on the bottom plate for temporary storage. When a small amount of residual water remains in the overflow tray, a moist root-inducing area can be formed at the bottom of the water storage seedling container, guiding the plant roots to continue to extend downwards. When there is too much water in the overflow tray and it submerges the plant roots, the water will flow into the external water storage tray through the overflow outlet for temporary storage.

[0011] Preferably, the inner surface of the side plate is provided with a guide groove, which is a series of grooves and / or rib grooves extending in the vertical direction.

[0012] Preferably, the guide root groove has a curved structure.

[0013] The root guide groove is used to guide plant roots to grow vertically downward along the inner wall of the side plate, reducing the roots from winding horizontally along the side plate.

[0014] Preferably, the lower part of the side plate is provided with at least one air shearing hole, which is located near the bottom plate. After the plant roots grow downward along the root guide groove to the lower part of the side plate, the root tips come into contact with the external air at the air shearing hole, thereby generating an air shearing effect, which encourages the root system to form more branching roots and absorbing roots inside the container.

[0015] Preferably, the root guide groove is arranged vertically or adjacently to the air shear hole, so that the root system can grow downward along the root guide groove to the vicinity of the air shear hole.

[0016] Preferably, the inner wall of the side plate is provided with a soil-proof filter at the air shear hole. The soil-proof filter can reduce the loss of seedling substrate from the air shear hole.

[0017] Preferably, the lower surface of the base plate is provided with support feet, which are used to create a gap between the base plate and the bottom surface of the overflow tray, so that excess water can enter the overflow tray and form a water storage space in the overflow tray.

[0018] Preferably, the side wall of the water storage tray is provided with a water level indicator line to indicate and control the amount of water retained in the tray, preventing the seedling substrate from becoming too wet due to prolonged high water levels. An artificial drainage outlet is provided at the bottom of the water storage tray.

[0019] Preferably, the outer side of the side plate is provided with an identification slot, which is a frame with an L-shaped cross-section.

[0020] Preferably, the base plate, side plate, overflow tray, and water storage tray are all made of plastic, such as PP, PE, HDPE, or ABS.

[0021] In use, insert the lower end of the side panel into the side panel slot on the base plate, and then connect and fix adjacent side panels using corner connectors or intermediate connectors, or directly insert adjacent side panels to form a single or multiple planting space. Then, nest the overflow tray and water storage tray under the base plate, add seedling substrate to the planting space, and plant ecological restoration plants or experimental plants. For scientific research experiments, multiple planting spaces of the same specifications can be set up for different plant species, different substrate conditions, different water treatment conditions, or different experimental treatment groups, and distinguished and recorded using structural components, identification plates, or numbered areas of different colors. After watering, excess water enters the overflow tray through the drainage and ventilation holes of the base plate for temporary storage. The small amount of water retained in the overflow tray forms a moist root-inducing area at the bottom. Plant roots grow downwards along the root guide grooves on the inner side of the side panel. When the roots reach the air shear holes distributed laterally below the side panel, the root tips come into contact with air and are pruned by air. After cultivation, the side plate that is connected to the base plate can be removed to take out the root ball in order to observe the degree of root penetration, the branching of lateral roots, and the condition of root coiling.

[0022] The beneficial effects of this utility model are as follows: 1. This utility model adopts a detachable and interlocking structure of bottom plate, side plate and water storage tray, which can realize flat transportation, stacking and storage and rapid on-site assembly, and is suitable for large-scale seedling cultivation and engineering application of ecological restoration plants; the inner side of the side plate is provided with vertically downward root guide grooves, which can guide the plant roots to grow downward and reduce the roots from winding horizontally; the lower part of the side plate is provided with air shear holes, which can realize air trimming when the roots reach the bottom of the container and promote the formation of branch roots; the bottom is nested with a water storage tray without air holes, which can temporarily store excess water and create a root-inducing environment through the residual water at the bottom.

[0023] 2. This utility model adopts standardized modular planting units, which can form multiple cultivation spaces with uniform specifications, facilitating parallel and control experiments with different plants, substrates, water conditions, and root control treatments; different colored structural components, identification plates, or numbered areas facilitate the identification of experimental groups, sample management, and recording of the cultivation process; water level marking lines or overflow structures in the water storage pan facilitate the control and comparison of the bottom water supply status of different cultivation units; and the detachable side plate structure reduces disturbance to the root ball during sampling, making it easier to observe and record plant root morphology.

[0024] 3. This utility model is applicable not only to plant seedling cultivation in vegetation ecological restoration projects, but also to scientific research experiments on plant root growth, root control effects, seedling substrate and water management.

[0025] 4. This utility model can be widely used in plant seedling cultivation, domestication and pre-transplanting cultivation in vegetation ecological restoration projects such as river and lake banks, reservoir drawdown zones, wetlands, water-land transition zones, ecological slope protection, artificial wetlands, mine revegetation and bare land restoration. It can also be used for scientific research such as plant root system architecture observation, comparison of root control seedling cultivation effects, plant culture control experiments under different substrate or water conditions, and screening of ecological restoration plants.

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings, but the present invention is not limited to the following embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example 1 like Figures 1 to 11 As shown, this utility model discloses a water-storage seedling container for vegetation ecological restoration. The water-storage seedling container includes a seedling area enclosed by the upper surface of the bottom plate 3, four side plates 1, and four corner connectors 2, and a water storage area enclosed by the lower surface of the bottom plate 3 and the water storage tray 5.

[0032] The base plate 3 is a square plate structure. The upper surface of the base plate 3 has downwardly extending side plate slots 3.4 and permeable drainage and ventilation holes 3.1. The side plate slots 3.4 are located along the perimeter of the base plate 3 and are used to install side plates 1. The drainage and ventilation holes 3.1 are distributed in the central area of ​​the base plate 3 to drain excess water from the seedling area and improve bottom ventilation. The lower surface of the base plate 3 has support feet 3.2 and fitting grooves 3.3. The support feet 3.2 are used to stably support the base plate 3 within the overflow tray 4, and the fitting grooves 3.3 are used to interlock with the upper insertion bosses 4.2 on the upper surface of the overflow tray 4.

[0033] Side panel 1 is made of plastic sheet. A lower tongue is provided at the lower end of side panel 1, which inserts into the side panel slot 3.4 on the upper surface of the base plate 3, thus vertically fixing side panel 1 to the perimeter of the base plate 3. Side panels 1 have side insertion parts on their left and right sides, and the corner connector 2 has connecting grooves. The side insertion parts of two adjacent side panels 1 are respectively inserted into the connecting grooves on different sides of the same corner connector 2, thereby achieving the connection and fixation of adjacent side panels 1.

[0034] The inner surface of the side plate 1 is provided with multiple root guide grooves 1.1, which extend vertically downwards. The root guide grooves 1.1 can be grooves or troughs formed by adjacent ribs. Both grooves and ribs can be straight lines, wavy lines, or curved lines, extending vertically along the side plate 1. After the plant roots contact the side plate 1, they grow downwards along the inner side of the side plate 1 under the guidance of the root guide grooves 1.1, thereby reducing the roots from winding laterally along the inner wall of the container.

[0035] The lower part of the side plate 1 is provided with multiple air shear holes 1.2, which are arranged in a row along the transverse direction and concentrated near the bottom plate 3. The air shear holes 1.2 can be circular, oblong, elliptical, or strip-shaped. When the plant roots grow downward along the root guide groove 1.1 to the vicinity of the air shear holes 1.2, the root tips come into contact with the external air, creating an air shearing effect, thereby promoting the generation of more branch roots inside the seedling substrate.

[0036] The inner side of the side plate 1 is provided with a soil-proof filter slot, into which a soil-proof filter can be detachably inserted. The soil-proof filter is used to reduce the loss of seedling substrate from the air shear hole 1.2, while maintaining the air ventilation conditions at the air shear hole 1.2.

[0037] The water storage tray 5 is a transparent disc-shaped structure without air holes. Multiple insertion grooves 5.1 are processed on the upper surface of the edge of the water storage tray 5. The lower insertion protrusion 4.3 on the lower surface of the edge of the overflow tray 4 is inserted into the insertion groove 5.1, and the overflow tray 4 is embedded and connected to the inner cavity of the water storage tray 5. A water storage cavity is formed between the inner surface of the water storage tray 5 and the outer surface of the overflow tray 4. A water level marking line is set on the outer side of the water storage tray 5. The water level marking line is used to indicate the appropriate water level in the water storage tray 5 to avoid excessive water storage and long-term over-wetting of the seedling substrate.

[0038] The upper insertion boss 4.2 on the upper surface of the overflow tray 4 interlocks with the fitting groove 3.3 on the bottom of the base plate 3, allowing the overflow tray 4 to be detachably installed under the base plate 3. An overflow port 4.1 is machined on the side of the overflow tray 4, connecting the inner cavity of the overflow tray 4 to the water storage cavity. After watering the seedling area, excess water flows into the overflow tray 4 through the drainage and ventilation holes 3.1 of the base plate 3 for temporary storage. The small amount of water remaining in the overflow tray 4 can form a moist root-inducing area at the bottom of the seedling container, guiding the roots to continue growing downwards. When the water level in the overflow tray 4 is too high and exceeds the overflow port 4.1, the water in the overflow tray 4 flows into the water storage cavity through the overflow port 4.1, ensuring that the water in the overflow tray 4 is always in a state where it does not contact the roots. When the water level in the water storage cavity is higher than the marking line, the artificial drainage port at the bottom of the water storage tray 5 is opened to release some water.

[0039] In use, first insert the four side panels 1 into the side panel slots 3.4 on the four sides of the base plate 3, and then use the corner connectors 2 to connect and fix adjacent side panels 1 to form a single planting space; then, install the overflow tray 4 under the base plate 3 and the water storage tray 5 under the overflow tray 4. Add seedling substrate to the planting space and plant ecological restoration plants or experimental plants. During plant growth, the roots extend downward along the root guide grooves 1.1 on the inner side of the side panel 1, are pruned by air near the air shear hole 1.2 at the bottom of the container, and continue to grow downward under the induction of residual water in the overflow tray 4.

[0040] Example 2 like Figures 12 to 14 As shown, the difference between this embodiment and embodiment 1 is that adjacent side plates 1 are directly interlocked with each other, and the shape of the base plate 3 is not limited to a quadrilateral, but can also be a pentagon, hexagon or more polygons of different moduli, forming a polygonal water storage seedling container planting unit.

[0041] Example 3 like Figure 15 and Figure 16 As shown, in this embodiment, multiple side plates 1, middle partitions, corner connectors 2 and intermediate connectors can be selectively plugged into each other to form a water storage and seedling raising assembly, thereby forming a double-cell, triple-cell or multi-cell planting space.

[0042] Two adjacent planting spaces can share a central partition or each can have its own side panel 1. Vertical root guide grooves 1.1 can be provided on both sides of the central partition to ensure that the plant roots in the two adjacent planting spaces can receive root guidance.

[0043] In this embodiment, the side panels 1, corner connectors 2, or intermediate connectors corresponding to different planting spaces can be made of different colors. For example, the structural components corresponding to the first planting space are green, the structural components corresponding to the second planting space are white, and the structural components corresponding to the third planting space are blue or other colors. Different colored structural components can be used to distinguish different plant species, different seedling batches, different ecological restoration project areas, or different experimental treatment groups, facilitating scientific research and engineering management.

[0044] Example 4 This embodiment illustrates the application of this invention in seedling cultivation for vegetation ecological restoration.

[0045] In vegetation restoration projects on river and lake banks, wetlands, reservoir drawdown zones, or water-land transition zones, the water-storage seedling container of this invention can be used for the pre-cultivation of emergent plants, wetland plants, herbaceous slope protection plants, or shrubs and grasses. During use, a seedling substrate suitable for the growth of ecological restoration plants is filled into the planting space. This seedling substrate can be garden soil, humus, river sand, expanded clay, coconut coir, wetland sediment amendment substrate, or a mixture thereof.

[0046] After planting, the roots grow downwards along the vertical root guide groove 1.1 on the inner side of the side plate 1, and are pruned by air at the air shear hole 1.2 at the bottom of the side plate 1. The small amount of water retained in the overflow tray 4 forms a moist root-inducing area at the bottom of the container, which can further promote the downward extension of the roots. After the plant has developed a relatively well-developed root system, the side plate 1 can be removed to take out the root ball, reducing damage to the root system when removing the plant from the pot, and the plant can be transplanted to the ecological restoration site.

[0047] Example 5 This embodiment is used as a control experiment for plant root growth status, root guidance and control effect, seedling substrate conditions, or bottom water supply conditions.

[0048] The base plate 3 is a multi-cell structure with multiple standard modular units. Each standard modular unit has the same size and structure. Each standard modular unit is enclosed by a side plate 1, a connector, and an overflow tray 4 to form an independent planting space. Each planting space is filled with the same or different seedling substrates and planted with the same or different types of experimental plants.

[0049] When conducting control experiments, some planting spaces can be designated as control groups, while other planting spaces can be designated as treatment groups. For example, different planting spaces can be configured with different substrate compositions, different bottom water storage capacities, different air shear hole 1.2 settings, or different plant species. The side panels 1, connectors, or identification plates corresponding to different treatment groups should be of different colors, or numbered identification plates should be installed in the identification slots 1.3 to facilitate differentiation, recording, and management by experimental personnel.

[0050] The water storage tray 5 is a transparent tray with water level markings on its outer wall, allowing researchers to control the amount of water retained in the tray and thus create a recordable and repeatable bottom-moistening root-inducing condition. During the growth of the experimental plants, the roots extend downwards along the vertical root guide groove 1.1 on the inner side of the side plate 1 and are pruned by air at the air shear hole 1.2 at the bottom of the side plate 1.

[0051] After the cultivation experiment is completed, the connector and side plate 1 can be removed sequentially. The plant can be taken out while keeping the seedling substrate and root ball as intact as possible for observation and recording of indicators such as the downward growth length of the root system, the branching status of the lateral roots, the degree of root coiling, and the integrity of the root ball. This structure is suitable for observing plant root system architecture, screening plants for ecological restoration, comparing the effects of root-controlled seedling cultivation, and conducting seedling cultivation experiments under different water management methods.

[0052] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0053] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
