Description

Technical Field

[0001] This utility model relates to the field of marine ecological aquaculture, and in particular to a device for simulating the growth of coastal wetland plants throughout their entire life cycle. Background Technology

[0002] Coastal wetlands, situated in the transitional zone between land and sea, extend from 6 meters below sea level to above the spring tide line. They comprise freshwater or brackish lakes and marshes connected to inland river basins, as well as river sections flowing into the sea that are not reached by seawater upstream. They represent one of the most biodiverse ecosystems on Earth. Due to their unique geographical location and ecosystem services, the conservation of coastal wetlands faces significant challenges.

[0003] To address the sharp decline in coastal wetland area and the degradation of its ecological functions, bioremediation has become an important means of restoring the productivity of coastal wetland ecosystems and establishing a long-term mechanism for coastal wetland protection. The selection of plant species for vegetation restoration in bioremediation should follow the principle of adapting to local conditions. Furthermore, the unique natural environmental conditions of coastal wetlands make plant species selection criteria more stringent and complex. Therefore, a coastal wetland plant full-life-cycle growth simulation device can efficiently pre-select plant species under simpler and more effective conditions, providing a reference for the ecological restoration of coastal wetlands.

[0004] The main shortcomings of current laboratory studies on plant growth in coastal wetlands are: 1) lack of in-situ observation of root growth during the seedling stage under tidal flooding conditions in coastal wetlands; 2) lack of simulation of air humidity in coastal wetlands; 3) lack of recycling of experimental saline water; and 4) lack of real-time comparative monitoring of the quality of experimental saline water and water in the incubator. Therefore, this invention discloses a simulation device for the entire growth cycle of coastal wetland plants to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A simulation device for the full growth cycle of coastal wetland plants includes a plant cultivation box and a self-circulating saline water tank. The plant cultivation box and the self-circulating saline water tank are connected to the water level control device through inlet and outlet water pipes. The plant cultivation box is equipped with a plant supplement light and a temperature and humidity control device. The plant cultivation box is equipped with a water quality testing device; The plant culture box is equipped with a detachable transparent culture tank assembly; The main body of the self-circulating saltwater tank is divided into a water collection layer, a filter layer, and a water purification layer from top to bottom; The self-circulating brine tank is equipped with a long-handled funnel at the top, and an automatic stirring device and a salinity sensor at the bottom of the funnel.

[0006] Furthermore, the separate transparent culture tank assembly consists of several rectangular transparent plastic plant culture tanks whose height decreases gradually from left to right.

[0007] Furthermore, the water inlet and outlet pipes inside the plant cultivation box consist of four PVC pipes of the same diameter, which are connected end to end and laid around the bottom of the plant cultivation box. Each PVC pipe has two rows of holes with a diameter of about 2cm. The spacing between the holes in the same row is 10cm, and the angles between the two rows of holes and the center of the ground are 30° and 60°, respectively.

[0008] Furthermore, the plant grow light is an LED light source, which can provide light sources with different wavelengths and light intensities, and the light cycle can be set.

[0009] Furthermore, the temperature and humidity control device is connected to a temperature and humidity sensor, and a temperature and humidity cycle can be set.

[0010] Furthermore, the water level control device controls the water pump and inlet / outlet to regulate the water level in the plant cultivation box via a water level sensor, and the water level cycle can be set.

[0011] Furthermore, the upper filter layer in the self-circulating saltwater tank consists of a fine mesh sand-trapping layer, a quartz sand layer, and a fluffy cotton layer from top to bottom.

[0012] Furthermore, the long-handled funnel at the top of the self-circulating brine tank displays the salinity of the brine in the purified water layer in real time via a salinity sensor. The salinity sensor is connected to a salinity controller, which can adjust the salinity of the brine in the purified water layer by controlling the switch of the feed inlet of the long-handled funnel.

[0013] Compared with the prior art, the main advantages of this utility model are: This device features a set of separate transparent culture tanks inside the plant culture box, providing a feasible solution for in-situ observation of plant root growth. This device simulates changes in air humidity in coastal wetlands, providing more optimized environmental conditions for research on the growth of plants in coastal wetlands.
