Description

Technical Field

[0001] This application relates to the technical field of identification devices, and in particular to an identification device for the salt and alkali tolerance of rice seedlings. Background Technology

[0002] Currently, soil salinization in my country is severe. At the same time, insufficient salt and alkali tolerance often leads to low rice yield and poor quality. Therefore, the selection and identification of rice seedlings with salt and alkali tolerance has become an important part of rice cultivation. The methods for identifying the salt and alkali tolerance of rice seedlings mainly include laboratory culture and field trials. When conducting identification in the laboratory, identification devices are often required to cultivate and identify rice seedlings.

[0003] When using the relevant identification device, rice seedlings are usually placed in petri dishes containing solutions of different concentrations of salt and alkaline for cultivation. Then, by observing the survival rate of the rice seedlings, varieties with strong salt and alkali tolerance can be quickly identified.

[0004] However, when using the above-mentioned methods for identification, rice seedlings often have high requirements for environmental temperature and light, while laboratory environments are usually relatively cold and have poor lighting conditions. This leads to some rice seedlings withering and becoming inactive due to low temperature and insufficient light during salinity and alkalinity testing, which can easily affect the final identification results and reduce the accuracy of the identification. Therefore, those skilled in the art have provided a device for identifying the salinity and alkalinity tolerance of rice seedlings to solve the problems mentioned in the background art.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a device for identifying the salt and alkali tolerance of rice seedlings. (Refer to...) Figure 2 Figure 3 A device for identifying the salt and alkali tolerance of rice seedlings includes a seedling board 1, with several seedling troughs 101 formed on the top of the seedling board 1, and a temperature control mechanism 2 for heat preservation on the top of the seedling board 1.

[0024] Several seedling clamping mechanisms 5 are located on the side walls of several seedling troughs 101 to assist in positioning rice seedlings.

[0025] The temperature control mechanism 2 includes a transparent cover 201, a rotating component 3, and a temperature control component 4. One end of the transparent cover 201 is installed on the top of the seedling board 1 through the rotating component 3, and the temperature control component 4 is installed on the inner wall of the transparent cover 201. The transparent cover 201 is made of transparent glass.

[0026] The rotating assembly 3 includes a support frame 301, a rotating block 302, and two torsion springs 303. One end of the support frame 301 is fixedly connected to the top of the seedling board 1, and one end of the transparent cover 201 is rotatably connected to the middle of the support frame 301 through the rotating block 302. The two ends of the two torsion springs 303 are fixedly connected to the side wall of the support frame 301 and the side wall of the rotating block 302, respectively.

[0027] The temperature control component 4 includes a mounting bracket 401, a temperature sensor 402, a microcontroller 403, a display screen 404, and a heating wire 405. The side wall of the temperature sensor 402 is fixedly connected to the inner top of the transparent cover 201 through the mounting bracket 401. The microcontroller 403 is fixedly connected to the inner top of the transparent cover 201. The display screen 404 is fixedly connected to the top of the transparent cover 201. The heating wire 405 is fixedly connected to the inner wall of the transparent cover 201.

[0028] Two plant growth lights 203 are also fixedly connected to the top inner side of the transparent cover 201, and several ventilation holes 202 are opened on the side wall of the transparent cover 201.

[0029] In this embodiment, firstly, supported by the support frame 301, the transparent cover 201 is rotated to open at the center of the support frame 301 via the rotating block 302. Then, the prepared saline-alkaline solution is poured into the seedling trough 101 on the seedling plate 1. Rice seedlings are then placed in the seedling trough 101 for cultivation and evaluation. Next, by releasing the transparent cover 201, the rotating block 302 is rotated at the center of the support frame 301 by the reaction force provided by the torsion spring 303. The transparent cover 201 is closed by rotating twice, thus enclosing the rice seedlings in the seedling trough 101. This effectively reduces heat loss and allows staff to observe the seedlings' survival from the outside. Ventilation holes 202 on the side wall of the transparent cover 201 ensure airflow, and the plant growth lamps 203 provide supplemental lighting for the seedlings. The transparent cover 201 provides sufficient light for the normal growth and development of rice seedlings. Simultaneously, a temperature sensor 402, supported and fixed by a bracket 401, can monitor the temperature inside the transparent cover 201 in real time. A microcontroller 403 processes the data from the temperature sensor 402, and the temperature value is displayed on a screen 404. This allows staff to quickly determine the temperature of the environment in which the rice seedlings are located. When the temperature sensor 402 detects a temperature drop, the microcontroller 403 receives and processes the signal, then controls the heating wire 405 to be energized. The energized heating wire 405 generates heat, thereby raising the temperature inside the transparent cover 201. This allows for real-time monitoring and control of the rice seedling cultivation environment temperature while providing sufficient light, ensuring that the temperature and light conditions in the rice seedling cultivation environment remain consistent and suitable. This avoids the impact of low temperatures and poor light conditions on the survival of rice seedlings, effectively reducing identification errors and improving the accuracy of identification results.

[0030] Furthermore, the seedling clamping mechanism 5 includes two positioning clamps 501 and a telescopic component 6, with one end of the two positioning clamps 501 mounted on the side wall of the seedling trough 101 via the telescopic component 6;

[0031] The telescopic assembly 6 includes two telescopic slides 601, two springs 602, and two telescopic slide rods 603. The two telescopic slides 601 are symmetrically opened on the side wall of the seedling trough 101. One end of each of the two springs 602 is fixedly connected to one end of each of the two telescopic slides 601. The two telescopic slide rods 603 are slidably connected to the side wall of each of the two telescopic slides 601. One end of each of the two telescopic slide rods 603 is fixedly connected to the other end of each of the two springs 602. The other end of each of the two telescopic slide rods 603 is fixedly connected to one end of each of the two positioning clips 501.

[0032] Based on the above embodiment, by pulling the positioning clips 501 open to both sides, the two positioning clips 501 slide open within the telescopic groove 601 via the telescopic slide rod 603. At this time, rice seedlings are placed in the seedling trough 101 and positioned between the two positioning clips 501. Then, the positioning clips 501 are released, and the reaction force provided by the spring 602 with a small elastic force causes the telescopic slide rod 603 to spring back and extend from within the telescopic groove 601. The springback extension of the telescopic slide rod 603 causes the positioning clips 501 to spring back and close. The closing of the positioning clips 501 clamps and positions the rice seedlings placed in the seedling trough 101. This achieves the effect of clamping, positioning, and assisting in the straightening of rice seedlings for cultivation and identification, thereby facilitating the normal cultivation and identification of rice seedlings within the seedling trough 101.

[0033] The implementation principle of the rice seedling salt-alkali tolerance identification device in this application embodiment is as follows: In use, firstly, supported by the support frame 301, the transparent cover 201 is rotated to open via the rotating block 302 in the middle of the support frame 301. Then, the prepared salt-alkali solution is poured into the seedling trough 101 on the seedling plate 1. Next, the positioning clips 501 are pulled open to both sides, causing them to slide open within the telescopic groove 601 via the telescopic slide rod 603. At this time, the rice seedling is placed in the seedling trough 101 and positioned between the two positioning clips 501. Then, the positioning clips 501 are released, and the reaction force provided by the spring 602 (with low elasticity) causes the telescopic slide rod 603 to be forced open from the telescopic groove 601. The inner spring extends, and the telescopic slide rod 603 extends, causing the positioning clamp 501 to spring back and close. The closing of the positioning clamp 501 clamps and positions the rice seedlings placed in the seedling trough 101, thus effectively facilitating the clamping, positioning, and alignment of the rice seedlings for cultivation and identification. This ensures the normal cultivation and identification of rice seedlings within the seedling trough 101. Next, by releasing the transparent cover 201, the torsion spring 303 provides a reaction force, causing the rotating block 302 to rotate in the middle of the support frame 301. The rotation of the rotating block 302 causes the transparent cover 201 to rotate and close. At this point, the closing of the transparent glass cover 201 closes the seedling trough 101. The rice seedlings inside the transparent cover 201 are enclosed, effectively reducing heat loss while allowing staff to observe their survival from the outside. Ventilation holes 202 on the side wall of the transparent cover 201 ensure proper airflow. Plant growth lights 203 provide supplemental lighting for the seedlings. A temperature sensor 402, supported by a bracket 401, monitors the temperature inside the transparent cover 201 in real time. A microcontroller 403 processes the data from the temperature sensor 402, and the display screen 404 shows the temperature readings, allowing staff to quickly determine the ambient temperature of the rice seedlings. After the sensor 402 detects a temperature drop, the microcontroller 403 receives and processes the signal, then controls the heating wire 405 to be energized. The energized heating wire 405 generates heat, thereby increasing the temperature inside the transparent cover 201. This allows for real-time monitoring and control of the temperature in the rice seedling cultivation environment while providing sufficient light for the seedlings. This ensures that the temperature and light in the rice seedling cultivation environment remain constant and suitable, avoiding the impact of low temperature and poor light conditions on the survival of the rice seedlings. This effectively reduces identification errors and improves the accuracy of identification results. Finally, by observing the survival of the rice seedlings in the seedling trough 101, the salt and alkali tolerance of the rice seedlings can be identified.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
