Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plant growth experiments and relates to a seawater submerged lawn experimental device used for testing the growth of lawns in a seawater submerged environment. Background Art
[0002] Lawns have important application value in environmental research, ecological restoration, landscape design and other fields. In the experimental research process, the seawater submerged lawn experiment can simulate a certain natural environment and study the growth status and ecosystem of the lawn. However, the traditional seawater submerged lawn experimental methods and devices often have many problems, such as experimental instability, complex operation, difficult control, etc., which have a certain impact on the accuracy and reliability of experimental research. The traditional experimental method is to set up a closed box in the laboratory to plant lawns, irrigate with seawater, open a drainage port at the bottom to let the seawater flow out, or soak in seawater. The biggest problem is that the seawater cannot be drained, resulting in salt accumulation in the soil where the lawn grows, affecting the experimental results, or conducting field experiments, directly opening up a piece of land in the field and irrigating with experimental seawater, which will also cause a large amount of seawater to remain.
[0003] Therefore, it is objectively necessary to develop a new type of special device for seawater flooding lawn experiments to improve the accuracy and reliability of the experiments and provide strong support for related research. Utility Model Content
[0004] The utility model aims to provide a seawater submerged lawn experimental device which can simulate the growth of lawn under the seawater submerged condition.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A seawater submerged lawn experimental device comprises a bottom plate, to which a plurality of side panels perpendicular to the bottom plate surface are connected, the bottom plate and the side panels define a box body, the side panels comprise side grille panels and blocking panels, and the blocking panels are detachably connected to the outer sides of the side grille panels.
[0007] Optionally, a slide groove is provided at the edge position of the top surface of the bottom plate, and the blocking plate is slidably connected in the slide groove.
[0008] Optionally, it also includes a plurality of U-shaped clips buckled on the top of the side panel, and the width of two inner walls of the U-shaped clips is equal to the sum of the widths of the grille plate and the blocking plate.
[0009] Optionally, a sealing device, such as a rubber sealing strip, is also provided on the outer edge of the blocking plate.
[0010] Optionally, the blocking plate is a transparent plate, such as an acrylic plate.
[0011] Optionally, a bottom grid plate is provided on the bottom plate to ensure that seawater can be discharged from the soil as much as possible while preventing the internal planting soil from being lost, and to support the soil while allowing the seawater to flow out so that it does not fall out. After being soaked in seawater, the outer transparent plates around and at the bottom, such as acrylic plates, are all removed to allow the seawater to flow out fully.
[0012] Optionally, the side grid plate and the bottom grid plate are an integral whole, fixedly connected to each other and cannot be disassembled, and the outer blocking plate and the bottom plate (acrylic plate) can be disassembled, similar to a circle of removable plates outside a basket. Without removing the surrounding plates, water will not leak out of the basket. After the plates are removed, all the water flows out.
[0013] The beneficial effects of the utility model include:
[0014] The advantage of the seawater submerged lawn experimental device disclosed in the utility model is that it can provide a relatively closed environment for conducting seawater submerged lawn experiments. By connecting the surrounding buckles and rubber strips, seawater leakage can be effectively prevented and the accuracy of the experiment can be guaranteed. At the same time, the blocking plate and the bottom plate are both made of acrylic plates with good transparency, so that the growth of the lawn can be clearly observed, which is convenient for recording and analyzing the experimental results.
[0015] When using the utility model to conduct experiments, first, the cube needs to be connected with the surrounding buckles and the joints need to be sealed to prevent seawater from leaking out. Then, the lawn needs to be planted on the internal grid structure and a certain amount of seawater needs to be injected. During the experiment, the growth of the lawn and parameters such as the water level change of the seawater need to be recorded regularly. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the figure: 1, bottom plate; 2, side grille plate; 3, blocking plate; 4, buckle; 5, slide groove; 6, through hole; 7, bottom grille plate. DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1 The figure shows an exemplary embodiment of the seawater submerged lawn experimental device disclosed in the utility model.
[0020] The seawater submerged lawn experimental device includes a base plate 1 and a plurality of side panels vertically mounted on the base plate surface. The base plate 1 and the side panels connected end to end form a box body with a accommodating cavity. The bottom of the box body, i.e., the base plate 1, can accommodate planting soil and other planting substrates, and lawns can be planted on the planting substrates.
[0021] The side panels include an inner side grille plate 2 and a detachable blocking plate 3 connected to the outer side of the grille plate. The side grille plate 2 is densely covered with many through holes 6. The blocking plate 3 is a waterproof whole plate. The blocking plate 3 arranged on the outer side of the side panels enables the box to contain fluids such as seawater. When planting lawn, the blocking plate 3 is removed from the side panels, and only the inner side grille plate 2 is retained to provide a breathable environment for the lawn in the box to grow normally.
[0022] Since a seawater submerged lawn experiment is to be conducted, when the lawn in the box grows to a length that meets the experimental requirements, the blocking plate 3 is installed on the outside of the side grid plate 2 to close the box so that the box can contain seawater. After the blocking plate 3 is installed, seawater is poured into the box to start the seawater submerged lawn experiment.
[0023] The seawater submerged lawn experimental device disclosed in the utility model also includes a U-shaped buckle 4, and the spacing between the two opposite side panels of the U-shaped buckle 4 is equal to the thickness of the blocking plate 3 and the side grid plate 2. Therefore, the U-shaped buckle 4 can be buckled on the edge of the side panel to ensure the fit between the blocking plate 3 and the side grid plate 2, and at least three U-shaped buckles 4 with equal spacing are arranged on the top of each side panel.
[0024] A slide groove 5 is also formed at the edge of the top surface of the base plate 1, and the width of the slide groove 5 is equivalent to the width of the blocking plate 3. The blocking plate 3 can be snapped into the slide groove 5. When installing the blocking plate, first insert the blocking plate 3 into the slide groove 5 so that the blocking plate 3 is installed on the base plate, and then use the U-shaped buckle 4 to buckle it on the top of the side panel to fix the blocking plate 3 on the outside of the side grille plate 2.
[0025] In order to ensure the accuracy of the experiment and avoid leakage of seawater in the box, rubber sealing strips are provided on the edges of the blocking plates.
[0026] In one embodiment, the bottom plate 1 and the blocking plate 3 are transparent acrylic plates, so that the experimenter can observe the growth and development changes of the lawn in the box.
[0027] In one embodiment, a bottom grid plate 7 is disposed on the bottom plate 1 , and similarly, the bottom grid plate 7 is also provided with through holes.
[0028] In one embodiment, the side grid plate 2 and the bottom grid plate 7 are integrally formed and fixedly connected to each other and cannot be disassembled, and the outer blocking plate 3 and the bottom plate 1 can be disassembled.
[0029] When cultivating the lawn, the outer panels are not inserted. When conducting the seawater submersion experiment, the bottom of the outer panels around the lawn are first inserted into the chute 5 at the bottom edge of the whole body, and then reinforced with the U-shaped buckle 4 to make the inner and outer layers fit tightly. The lower outer layer panel fits tightly with the protruding part of the bottom edge of the whole body through the U-shaped buckle 4 to prevent seawater from seeping out.
[0030] Some of the ways and scenarios of using the utility model are described as follows:
[0031] The utility model is used to set the soaking time during the experiment, such as setting a control group of 10 minutes, 30 minutes, or 1 hour per day. The purpose of the experiment is to verify that in the coastline part, some areas will not be invaded by seawater most of the time, but will be invaded by seawater and soaked for several hours or days under special circumstances, to study which lawn grass can adapt to or select the best lawn grass for planting. During the experiment, the lawn grass is planted in the box, and the acrylic plate is fixed around the grille to be impermeable. At this time, the whole device is in a water-holding state, and the experimental seawater is poured in. After the time is set, the acrylic plate around and at the bottom is removed to allow the seawater to flow out from the grille as much as possible. The control group is irrigated and rinsed with clean water, and the experimental group is not rinsed with clean water. The experiment lasts for 1 month, and the growth state and mortality rate of the experimental lawn are determined. Another experiment is to spread experimental grass seeds, repeat the above experiment, and observe the germination rate of the grass seeds. This experiment is carried out indoors or at an experimental base. The whole device is not large in size and is not exposed to strong light. The time of each experiment does not exceed 3 hours, and the evaporation can be ignored. If the evaporation needs to be measured, a lid and an evaporation measurement device will be added to measure the evaporation. If salt accumulation is an issue, a control group can be set up to measure salt accumulation as part of the experiment.
[0032] The above-mentioned related explanations and descriptions of the embodiments are for the convenience of ordinary technicians in the technical field to understand and apply the utility model. It is obvious that those familiar with the technology in the field can easily make various modifications to these contents and apply the general principles described here to other embodiments without creative work. The utility model is not limited to the above-mentioned related explanations and descriptions of the embodiments. Improvements and modifications made by technicians in the field based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
