Description

Technical Field

[0001] This utility model relates to the field of wetland plant research technology, specifically to an experimental device for studying the ecological performance of key wetland plants in Butterfly Lake. Background Technology

[0002] The hydrological rhythms of lakes and other wetlands cause alternating wet and dry periods in sandbar wetlands, leading to significant differences in aquatic plant communities across seasons. During the dry season, sandbar wetlands emerge above the water, exhibiting wetland plant communities dominated by sedges and emergent plant communities dominated by reeds. During the wet season, these wetland and emergent plant communities disappear as the sandbar wetlands are submerged, giving rise to submerged plant communities dominated by Potamogeton malaianus, Vallisneria natans, and Hydrilla verticillata. For butterfly-shaped lakes, which exhibit typical flood and recession patterns, and whose wetland plant communities are sensitive to these hydrological changes, it is necessary to study the impact of hydrological changes on the growth of wetland plants in butterfly-shaped lakes. This will provide theoretical support for wetland biodiversity conservation and ecological restoration. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example

[0023] Please see Figure 1The diagram shown is a structural schematic of the experimental apparatus in this embodiment. The experimental apparatus includes:

[0024] The container 10 with an open top has a scale 13 on its inner or outer side wall that is perpendicular to the bottom surface of the container 10, and an inlet valve 14 and an outlet valve 16 are respectively installed at the top and bottom of the side wall of the container 10.

[0025] A hanging rack 20 is placed at the opening of container 10, which is used to suspend the planting bucket 40 planted with key wetland plants, so that the planting bucket 40 is located inside container 10.

[0026] A peristaltic pump 30 is connected to a water pumping pipe 31, one end of which is located inside the container 10. The peristaltic pump 30 is used to pump water out of the container 10 or pump external water into the container 10 through the water pumping pipe 31.

[0027] In this application, water from the butterfly-shaped lake is introduced into container 10 through inlet valve 14. Container 10 can be used to simulate the habitat environment of key wetland plants in the butterfly-shaped lake. Planting buckets 40 containing key wetland plants of the butterfly-shaped lake are suspended in container 10 using hanging frame 20. By observing the growth of key wetland plants in planting buckets 40, the influence of key wetland plants on the growth of butterfly-shaped lake can be studied.

[0028] The container 10 is cylindrical, such as round or square, with a height generally between 1.5m and 3.0m, and a base diameter or side length between 0.5m and 2m. The material can be PVC, PU, ​​or acrylic, with the appropriate light transmittance selected based on the light requirements of the key wetland plant being studied. The container 10 can be a single-piece molded container or formed by connecting the cylindrical wall 11 and the base 12. The connection method is not limited, as long as it ensures that the container 10 is leak-proof. For example, the cylindrical wall 11 and the base 12 can be connected by heat fusion, mechanical connection, or clamp-on connection. In this embodiment, the container 10 is connected by heat fusion of the cylindrical wall 11 and the base 12, with an open top, a cylindrical shape, a base diameter of 1m, a height of 2m, and is made of semi-transparent PVC.

[0029] A scale 13 perpendicular to the bottom surface of the container 10 is provided on the side wall of the container 10. The scale 13 is used to visually observe the water depth inside the container 10. The scale 13 can be located on the inner or outer side wall of the container 10. When the container 10 is made of opaque or semi-transparent material, the scale 13 is located on the inner side wall of the container 10; when the container 10 is made of transparent material, the scale 13 is located on the outer side wall of the container 10. In this embodiment, the length of the scale 13 is equal to the height of the container 10, its length is 2m, and its smallest division is millimeters.

[0030] In this embodiment, an inlet pipe 15 with a diameter of 8mm is connected to the outlet end of the inlet valve 14. The inlet pipe 15 is placed inside the container 10 with its outlet end pressed against the inner wall of the container 10. Water from the butterfly-shaped lake is introduced into the container 10 through the inlet valve 14 and the inlet pipe 15. The close contact between the outlet end of the inlet pipe 15 and the inner wall of the container 10 ensures minimal water disturbance during water intake. An outlet valve 16 is installed at the bottom of the side wall of the container 10 for emptying the container 10.

[0031] The hanging frame 20 is made of metal or wood with good load-bearing capacity. In this embodiment, the hanging frame 20 is made of metal. The planting bucket 40 is frustum-shaped with a bottom diameter of 20cm and a height of 18cm. The side walls and bottom of the planting bucket 40 are provided with several small holes for water inlet and outlet. The planting bucket 40 is filled with in-situ soil and planted with wetland plants 41. The planting bucket 40 is suspended from the hanging frame 20 using a nylon rope 50. Specifically, the bottom end of the rope 50 is connected to the handle of the planting bucket 40, and the top end is connected to a hook or hanging ring, which is then fixed to the hanging frame 20.

[0032] In this embodiment, to suspend a larger number of planting buckets 40, the suspension frame 20 is composed of several suspension rods 21 that are intersected at the center. Each suspension rod 21 is of equal length and can be made of steel or wood. When the suspension rods 21 are made of steel, they are intersected at the center and welded together. When the suspension rods 21 are made of wood, they are intersected at the center and fixed together with bolts. To ensure the suspension frame 20 is placed more stably at the opening of the container 10, a slot corresponding to each suspension rod 21 is provided at the edge of the opening of the container 10. The outer end of each suspension rod 21 is placed in the slot, which limits its movement and prevents it from shifting.

[0033] The peristaltic pump 30 is connected to a water suction pipe 31, one end of which is placed inside the container 10. This end of the water suction pipe 31 is fixed to the inner wall of the container 10 and is lower than the bottom of the suspended lowest planting bucket 40. In this embodiment, the flow rate of the peristaltic pump 30 ranges from 0.03 mL / min to 1500 mL / min. In this embodiment, a graduated drain bucket 32 ​​is also included, which is connected to the water suction pipe 31 to receive the water output from the peristaltic pump 30.

[0034] In this application, the peristaltic pump 30 and the pumping pipe 31 can be used to adjust the water depth in the container 10, thereby simulating the butterfly lake habitat environment at different water levels and simulating the rise and fall of water. By controlling the flow rate of the peristaltic pump 30, the speed at which the water level rises or falls in the container 10 can be controlled, thereby simulating the rise and fall of water at a specific speed.

[0035] This invention's device is lightweight and easy to assemble. When erected near the butterfly-shaped lake, water from the lake is introduced into container 10, allowing for a more accurate simulation of the habitat environment of key wetland plants in the lake. This device can be used to conduct various observational experiments on key wetland plants in the butterfly-shaped lake, including but not limited to the following:

[0036] (1) By adjusting the water depth in container 10 and the hanging height of planting bucket 40, the water depth of wetland plant 41 in planting bucket 40 is adjusted. By observing the growth of wetland plant 41 under different water depths and different water durations, the influence of water depth and water duration on the growth of wetland plant 41 is analyzed.

[0037] (2) By controlling the flow rate of the peristaltic pump 30, water in the container 10 is pumped out at a specific speed or external water is pumped into the container 10 at a specific speed, so as to simulate different water receding speeds or different water rising speeds. By observing the growth of wetland plants 41 under different water receding or rising speeds, the influence of water receding and rising speeds on the growth of wetland plants 41 is analyzed.
