Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental treatment technology for plants, specifically an experimental device for treating plants to withstand waterlogging stress. Background Technology
[0002] In existing technologies, waterlogging stress treatment is a commonly used experimental treatment method in research on plant waterlogging tolerance and related fields. The main purpose of this experiment is to study the response mechanism of plants to waterlogging damage, including physiological, biochemical, and molecular changes, to understand how plants adapt to or resist waterlogged environments. This allows for the screening of plant varieties or genotypes with waterlogging tolerance characteristics, providing waterlogging-tolerant germplasm resources for agricultural production and ecological restoration, exploring the expression and regulation mechanisms of waterlogging-related genes, providing a theoretical basis for breeding waterlogging-tolerant crop varieties through genetic engineering, and assessing the growth, development, and yield loss of different plants under waterlogging conditions. This provides a scientific basis for formulating reasonable farmland drainage and irrigation management measures and ecosystem protection strategies.
[0003] The following are common methods for treating waterlogging stress in plants in the existing technology:
[0004] Field flooding method: Under natural field conditions, the water level is artificially controlled to partially or completely immerse the plant roots in water, simulating a waterlogging environment. Different flooding depths and durations can be set according to research needs, such as shallow flooding (water surface covers the base of the plant) and deep flooding (water surface approaches or exceeds the top of the plant), with flooding durations ranging from several days to several months.
[0005] Potted plant flooding method: Plant the plant in a flowerpot, then place the flowerpot in a container or pool of water to keep the soil in the flowerpot saturated with water or to partially submerge the plant. This method allows for easy control of flooding conditions and can be used to study the effects of different soil textures, fertility, and other factors on plant waterlogging tolerance.
[0006] Hydroponic flooding method: Plants are cultivated using a hydroponic system. By increasing the water level in the hydroponic container, the plant roots are completely submerged in the water, and the dissolved oxygen, nutrients and other conditions in the water are controlled. This method can precisely control environmental factors and is often used to study the physiological response and signal transduction mechanism of plant roots to flooding stress.
[0007] The hydroponic submersion method is the most common experimental method in existing technologies, especially in laboratories. The specific experimental setup of the existing hydroponic submersion method is relatively simple. Usually, an experimental box is set up, and the hydroponic plants are placed in the experimental box for submersion. However, the control of various conditions in the experimental box is not very precise or rapid. In addition, the placement of various sensors in the existing technology is not reasonable enough. When placing hydroponic plants, it is possible to damage the sensors, which is not worth the risk.
[0008] In addition, the operating space inside the test chamber cannot be adjusted in the existing technology. If there are few plants to be tested, but the same amount of water is required, it will result in a waste of water resources.
[0009] Therefore, in order to solve the above problems, it is necessary to develop an experimental device for treating waterlogging stress in plants that has a reasonable structure, protects all sensors, and saves water resources. Utility Model Content
[0010] The purpose of this invention is to address the shortcomings of existing technologies by providing an experimental device for treating waterlogging stress in plants; the technical solution is as follows:

[0015] Furthermore, the liquid level sensor, temperature sensor, pH sensor, and oxygen content sensor inside the protective mesh cover are all located within this placement area.
[0016] Furthermore, the inlet and outlet pipes are located on both sides of the protective mesh cover, extending downwards from the bottom plates on both sides of the protective mesh cover.
[0017] Furthermore, the experimental box has at least two rings of card slots, and adjacent card slots are equally spaced.

[0032] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0033] like Figure 1 and Figure 2 As shown, an experimental device for treating waterlogging stress in plants includes an experimental chamber 1, a processor 2, and a controller 3. Several plant cultivation containers 4 are placed inside the experimental chamber 1, and the experimental chamber 1 is also equipped with a liquid level sensor 5, a temperature sensor 6, a pH sensor 7, and an oxygen content sensor 8. Each sensor is connected to the processor 2, which processes the information from each sensor and displays the data.
[0034] It also includes a heating water tank 9, which is equipped with a heater 10. The processor 2 is connected to the controller 3, which controls the heater 10 in the heating water tank 9. The heating water tank 9 is also equipped with a water inlet pipe 11, which is connected to the experimental chamber 1 and is equipped with a water pump 12. The experimental chamber 1 is also equipped with a water outlet pipe 13, which is equipped with a solenoid valve 14.
[0035] A protective mesh cover 15 is installed in the middle of the experimental chamber 1, and the liquid level sensor 5, temperature sensor 6, pH value sensor 7 and oxygen content sensor 8 are all installed inside the protective mesh cover 15.
[0036] like Figure 3 and Figure 4As shown, it also includes several sets of closed baffles 16 for adjusting the container space; the bottom plate of the experimental box 1 is provided with several inner and outer rings of slots 17, the size of the closed baffle 16 is consistent with the range of the slots 17 on the bottom plate, and the bottom of the closed baffle 16 is provided with a card plate 18, which is installed in the slots 17 to fix the closed baffle 16 in the experimental box 1, and the area enclosed by the closed baffle 16 is the placement area of the plant cultivation container 4;
[0037] Furthermore, the liquid level sensor 5, temperature sensor 6, pH value sensor 7, and oxygen content sensor 8 inside the protective mesh cover 15 are all located within this placement area; the water inlet pipe 11 and the water outlet pipe 13 are located on both sides of the protective mesh cover 15, and the water inlet pipe 11 and the water outlet pipe 13 extend downward from the bottom plate on both sides of the protective mesh cover 15.
[0038] The test chamber 1 has at least two rings of slots 17, and adjacent slots 17 are equally spaced; the test chamber 1 has a cuboid structure, a cube structure, or a circular structure; the shape of the closed baffle 16 inside the test chamber 1 is set according to the shape of the test chamber 1, and is set as a rectangular baffle, a square baffle, or a circular baffle; the bottom plates 18 of the closed baffle 16 are all covered with sealing strips.
[0039] The specific working process and principle of this device are as follows: The water in the experimental chamber of this device is a flowing water system. Water is continuously injected into the experimental chamber through a water pump and an inlet pipe, and continuously drained through an outlet pipe and a solenoid valve. The water level is controlled by a liquid level sensor to keep it 3-5 cm above the soil surface in the plant cultivation container. The water temperature is controlled by a temperature sensor to keep it at around 23±0.5℃. The continuous flow of water in the experimental chamber can simulate the waterlogging resistance of tree roots on the bank, thus improving the accuracy of the test. In addition, the pH value in the experimental chamber is monitored in real time by a pH sensor, and the oxygen content of the water in the experimental chamber is monitored by an oxygen content sensor. Real-time monitoring of various data information in the experimental chamber effectively controls the experimental data and improves the accuracy of the test.
[0040] In this device, a protective mesh is set in the middle of the experimental chamber, and each sensor is placed inside the protective mesh. On the one hand, it can effectively protect the internal sensors and prevent them from being accidentally damaged when the plant cultivation container is placed or removed; on the other hand, it can be used with the sealing baffle to adjust the internal space of the container.
[0041] The experimental chamber of this device has many grooves inside and multiple annular closed baffles. The lower end of each closed baffle has a retaining plate and is covered with a sealing strip. By selecting a groove and installing the retaining plate into it, the space inside the closed baffle becomes the experimental area. Plant cultivation containers can be placed in this area, and water can be added to it. When conducting experiments with different numbers of plant cultivation containers, different area sizes can be selected by using the closed baffles, which effectively saves water resources and does not require filling the entire experimental chamber. The structure is reasonable.
[0042] Furthermore, when the volume of the experimental chamber changes, it is necessary to ensure that all the sensors inside are always located within the experimental area. This device places the protective mesh in the middle position, so no matter what size of the enclosed baffle is selected, the protective mesh is always located within the experimental area, effectively monitoring various data. The structure is reasonable and ingenious.
[0043] In addition to the fact that the positions of each sensor must correspond to the experimental area, the positions of the inlet and outlet pipes must also correspond. Therefore, this device sets the inlet and outlet pipes on both sides of the protective mesh cover. So no matter what size of closed baffle is selected, the inlet and outlet pipes are always located inside the experimental area, which facilitates water intake and drainage and has a reasonable structure.
[0044] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims.
