Description

Technical Field

[0001] This utility model belongs to the field of ecological restoration technology, specifically relating to a plant growth container for ecological restoration. Background Technology

[0002] In the field of ecological restoration, especially in scenarios such as slope greening, saline-alkali land management, desertification control, and mine reclamation in water-scarce areas, plant growth containers are core equipment for maintaining vegetation survival. Currently, mainstream container technologies are mainly divided into two categories: traditional plant growth containers and plant growth containers with simple water storage functions.

[0003] Traditional plant growing containers, primarily ordinary planting pots and precast concrete troughs, only possess basic soil-bearing capacity and lack active water collection, storage, and replenishment mechanisms, relying entirely on artificial irrigation. These containers face significant drawbacks in arid and semi-arid regions, such as ineffective rainwater collection and utilization, with natural rainfall utilization rates below 20%, water evaporation losses exceeding 70%, and vegetation survival rates generally below 60%.

[0004] Plant growth containers with simple water storage functions add a water storage layer and absorbent cotton rope to the bottom of traditional plant growth containers, achieving limited passive water replenishment. Compared with traditional plant growth containers, the water supply effect is better, but there are also significant drawbacks. For example, although rainwater is stored in the bottom water storage chamber, there is a lack of active water collection structure; the cotton rope is used to conduct water, but the conduction efficiency is uncontrollable, and the conduction path is easily blocked or over-absorbed due to alternating soil moisture, leading to drought or oxygen deficiency in the plant roots. Both types of containers have design flaws. On the one hand, rainwater collection relies solely on the container opening, and the small water collection area of ​​the opening leads to insufficient water collection; on the other hand, it cannot utilize condensation water and dew from deep soil layers, resulting in water waste. In addition, during maintenance, due to insufficient water, artificial irrigation is required to maintain plant growth, which leads to high maintenance costs, poor sustainability, and high energy consumption in complex terrain or remote areas. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a plant growth container for ecological restoration, solving the issues of dependence on external water sources and low plant survival rates.

[0029] Example 1

[0030] This embodiment discloses a plant growth container for ecological restoration, including a container body 1, which is a hollow column with an open top. The upper part of the container body 1 is provided with a rainwater / dew collection top edge 3. The inner wall of the middle section of the container body 1 is provided with an annular water storage box 9 along its circumference. A condensation bottom plate 6 is provided above the water storage box 9. The condensation bottom plate 6 is a circular plate with a high center and low periphery. A space is left between the condensation bottom plate 6 and the inner wall of the container body 1.

[0031] The container body 1 has multiple guide holes 11 on the side wall of the condensing base plate 6, and a rainwater / dew collection guide channel 10 is provided around the side wall of the container body 1. The bottom of the rainwater / dew collection guide channel 10 is flush with the guide holes 11.

[0032] It also includes multiple water-absorbing strips 12, one end of which is located inside the water storage box 9, and the other end of which passes through the condensing bottom plate 6 and extends into the inner cavity of the container body 1 above the condensing bottom plate 6.

[0033] Its functions are as follows: The inner cavity of the container body 1 above the condensing bottom plate 6 is used to fill the substrate 8. An open rain (dew) water collection and diversion channel 10 is set on the outer wall of the container body, which can expand the rainwater collection area. Even under light rainfall, the rainwater collected on the outer walls of the container can be gathered into the water storage box 9, solving the limitation of traditional containers that only rely on top precipitation; After the condensing bottom plate 4 loses heat at night, the surface temperature of the bottom plate 4 is lower than the soil water vapor dew point, promoting condensation. The "high in the middle and low around the edges" design accelerates the water flow into the water storage box, realizing "soil water vapor condensate recovery"; At the same time, when the air humidity is relatively high... When the water level is high, it can collect dew to supplement the plants' water needs. It can effectively store excess rainwater or irrigation water that seeps into the substrate 8, water vapor evaporated from the soil below the bottom of the plant growth container condensed by the condensation base plate 6, and rainwater and dew collected by the external rain (dew) water collection and diversion channel 10 for the plants' growth needs. The water-absorbing strip 12 is made of non-woven fabric and other new water-absorbing materials. Through the capillary action of the fiber material in the strip, water can be transferred bidirectionally between the water storage box and the substrate, avoiding the substrate from being too dry or too wet, so as to adapt to the water requirements of the ecological restoration plants.

[0034] The system efficiently collects natural precipitation (rainwater and dew) and soil water vapor condensation, reducing dependence on external water sources and enhancing plant survival rates.

[0035] The container body 1 in this embodiment is made of polypropylene plastic, and is cylindrical in shape, with a height of 400mm, an inner diameter of 300mm, and a wall thickness of 1mm. It has a 20mm wide rainwater / dew collection edge 3 at the top. The condenser base plate 6 is also made of polypropylene plastic, with six evenly arranged absorbent strip holes 13, each 5mm in diameter. Non-woven absorbent strips 12 are inserted through the absorbent strip holes 13. The condenser base plate 6 has a diameter of 300mm and a wall thickness of 2mm. Four support columns 7, made of polypropylene plastic and 50mm high, are evenly placed on the condenser base plate 6. These four support columns 7 are placed in the water storage box 9. The plant growth substrate 8 is supported on the condenser base plate. The water storage box 9 is made of polypropylene plastic and is shaped like a circular trough. One side of the water storage box uses the inner wall of the container body as the trough wall. The circular trough has a cross-sectional width of 40mm, a height of 40mm, and a wall thickness of 2mm. The externally open rainwater (dew) collection and diversion channel 10 is made of polypropylene plastic, surrounds the outer wall of the container body, is 10mm wide and 10mm high, and the lowest end is connected to the water storage box 9 through a diversion hole 11 with a diameter of 6mm.

[0036] In this embodiment, after the substrate 8 is filled, an anti-evaporation top plate 4 is placed on the upper surface of the substrate 8. A distance is left between the anti-evaporation top plate 4 and the inner wall of the container body 1, and the anti-evaporation top plate 4 has plant growth holes 5 for plant growth. The anti-evaporation top plate 4 blocks direct sunlight, reduces surface evaporation, and minimizes substrate moisture loss. The anti-evaporation top plate 4 is composed of two semicircles made of polypropylene plastic, with a higher center and lower edges, a diameter of 300mm, and a wall thickness of 1mm. A plant planting hole 5 with a diameter of 80mm is located in the center. The anti-evaporation plate is divided into two halves for easy installation and removal.

[0037] This embodiment utilizes rainwater (dew) collection, condensate recovery, and anti-evaporation measures to ensure that a single water storage can meet the plant's water needs for 20-45 days, reducing irrigation water consumption by more than 50%. Through water regulation and nutrient supply measures, the substrate inside the container guarantees the plant's water and fertilizer requirements, significantly improving the plant survival rate to over 95%. The water-absorbing strips greatly reduce irrigation costs, extending the maintenance and management cycle to 4-6 times that of conventional containers, meeting the environmental protection requirements of ecological restoration projects, and reducing maintenance and management costs by more than 30%.

[0038] In this embodiment, at least two support columns 7 are provided between the condenser base plate 6 and the inner bottom of the water storage box 9. Each support column 7 is evenly distributed around the circumference of the condenser base plate 6 to stably fix the condenser base plate 6 above the water storage box 9.

[0039] In this embodiment, the condensing base plate 6 is provided with multiple condensing protrusions in the radial direction. Each condensing protrusion can form a corrugated protrusion, which increases the condensing area, enhances the condensation efficiency of soil water vapor, and guides water flow into the water storage box 9.

[0040] In this embodiment, each flow guide hole 11 is evenly distributed along the circumference of the container body 1.

[0041] In this embodiment, the inner bottom of the container body 1 is a screen base 15, which is made of polypropylene plastic screen with a mesh diameter of 10mm. The screen base 15 and the condensation bottom plate 6 form a soil water vapor collection space 14. In this embodiment, the soil water vapor collection space 14 also serves as an isolation layer for saline-alkali land.

[0042] In this embodiment, multiple absorbent strips 12 are evenly distributed around the container body 1. The absorbent strips 12 are made of non-woven fabric and other new absorbent materials. The water conduction rate is adaptively adjusted through the capillary action of the fiber material in the strip, maintaining a certain moisture content in the substrate and avoiding the substrate from being too dry or too wet. The absorbent strips 12 pass through the reserved holes 13 in the condensation bottom plate, with the lower part submerged 50mm below the water surface of the water storage box 9 and the upper part extending to 2 / 3 of the height of the substrate 8.

[0043] This embodiment also takes into account the poor soil characteristics of the ecological restoration area, by placing slow-release fertilizer and microbial agents inside the water storage box 9. Preferably, nutrient sticks containing nitrogen, phosphorus, and potassium compound fertilizer and microbial agents are used, which are then soaked in water to simultaneously improve soil fertility and microecology, achieving integrated water and fertilizer management and reducing the frequency of manual fertilization. The substrate 8 uses a modified soil mixture of peat moss, perlite, and volcanic rock in a 3:3:4 ratio, with a thickness of 260mm.

[0044] Assemble the above components and plant the plant in the growth container. After at least 30 days of manual management and once the plant has established itself, transport the plant growth container and the plant together to the abandoned mining area. The lifting ring 16 can be used for convenient transportation. Level the land in the area where the plant growth container will be placed, bury the condenser base plate 6 and below in the soil, leaving the area above the condenser base plate 6 exposed to the air to facilitate the collection of soil water vapor below the base 15.
