They are now widely cultivated in temperate regions around the world and are important food crops in many places in Northeast, North, Northwest, and South China. In order to expand the planting range of potatoes, during the potato cultivation process, it is necessary to identify the cold tolerance of potato seedlings, select potato seedlings with strong cold tolerance, and then continue the cultivation.

Next, extend the third electric cylinder 31 and the fourth electric cylinder 32.

[0049] As Figures 1 to 10 shown, a device for identifying the cold tolerance of potato seedlings at the seedling stage, on the basis of Example 1, further includes:

[0050] The cultivation mechanism includes multiple groups of connecting rods 40, multiple groups of frames 41, multiple groups of fourth motors 42, multiple groups of conveyor belts 43, multiple groups of fifth motors 44 and multiple groups of fifth electric cylinders 45. A camera is arranged in the space on the right side inside the box body 1. One ends of multiple groups of connecting rods 40 are all rotatably installed in the space on the right side inside the box body 1. Multiple groups of fourth motors 42 are respectively fixedly installed on multiple groups of connecting rods 40. Multiple groups of frames 41 are respectively rotatably installed on multiple groups of connecting rods 40. And the output shafts of multiple groups of fourth motors 42 are respectively connected to one ends of multiple groups of frames 41. Multiple groups of conveyor belts 43 are respectively installed on multiple groups of frames 41. Multiple groups of fifth motors 44 are respectively installed on multiple groups of frames 41. And multiple groups of fifth motors 44 respectively provide power for multiple groups of conveyor belts 43. One ends of multiple groups of fifth electric cylinders 45 are all rotatably installed in the space on the right side inside the box body 1. The other ends of multiple groups of fifth electric cylinders 45 are respectively rotatably installed on multiple groups of connecting rods 40;

[0051] The staff controls the electrical equipment on the device through the touch screen 5 and displays the operating conditions of each electrical component in the device. By extending multiple first electric cylinders 3, multiple first guide rails 2 slide inside the box body 1, and the left parts of the multiple first guide rails 2 are extended to the left side of the box body 1. Then, the clamping mechanism moves on the multiple first guide rails 2, so that the clamping mechanism moves to the left side of the box body 1. Then, the seedling raising pots are placed on the top of the support seats 8. The second motor 13 is turned on, driven by the speed reducer 12, and then driven by two sets of positive and negative lead screws 11, so that the two sets of clamping plates 10 move towards each other to clamp the seedling raising pots. Then, multiple first electric sliders 6 slide on the two sets of first guide rails 2 simultaneously to adjust the positions of the potato seedlings. Then, the multiple first electric cylinders 3 contract, so that the multiple first guide rails 2 reset, and the touch screen 5 closes the left part of the box body 1. By operating multiple rolling door drivers 16, multiple rolling doors 17 are loosened respectively, so that the multiple rolling doors 17 divide the inside of the box body 1 into three spaces. Then, by operating two sets of first exhaust pumps 20, air is discharged into multiple first sealing air bags 18 and multiple second sealing air bags 19, so that the multiple first sealing air bags 18 and the multiple second sealing air bags 19 expand to seal the gaps between the multiple rolling doors 17 and the box body 1. Then, the potato seedlings are conveyed into the left space inside the box body 1 by the clamping mechanism. Two sets of second solenoid valves 27 are closed, and the second exhaust pump 23 is turned on, so that the air inside the box body 1 flows through the second exhaust pump 23, the rear part of the circulation pipe 22, the humidifier 24 and the air injection pipe 25 in sequence, and then returns to the box body 1. And in this process, the air inside the rear part of the circulation pipe 22 is cooled by the semiconductor refrigeration plate, so that a dry and cold low temperature is formed in the left space inside the box body 1, or water is discharged into the humidifier 24. During the air circulation process, the humidifier 24 is turned on to atomize the water, so that the water mist and the low temperature air enter the left space inside the box body 1 together, so that a wet and cold low temperature is formed in the left space inside the box body 1, or after cooling for a period of time, two sets of first solenoid valves 26 are closed, and two sets of second solenoid valves 27 are opened, so that the air inside the box body 1 flows through the second exhaust pump 23, the front part of the circulation pipe 22, the humidifier 24 and the air injection pipe 25 in sequence, and then returns to the box body 1. And in this process, the air inside the rear part of the circulation pipe 22 is heated by the heating element, so that the temperature inside the left space inside the box body 1 rises. Then, the above steps are repeated to continue cooling, and repeated repeatedly, so that a high and low temperature violently changing environment is formed in the left space inside the box body 1. After the potato seedlings are subjected to low temperature, the left space inside the box body 1 is heated again to evaporate the moisture on the surface of the potato seedlings. Then, the internal pressures of the multiple first sealing air bags 18 and the multiple second sealing air bags 19 are released respectively through the electronically controlled pressure relief valves on the multiple conveying pipes 21. Then, by operating multiple rolling door drivers 16, the multiple rolling doors 17 are rolled up respectively. The potato seedlings are conveyed into the middle space inside the box body 1 by the clamping mechanism. Then, the potato seedlings are conveyed into the middle space inside the box body 1 by the clamping mechanism again. By turning on the third motor 33,Drive the fourth electric cylinder 32 to rotate to adjust the angle of the negative electrode end 35. Then, slide the second electric slider 29 and the third electric slider 30 on the second guide rail 28 to adjust the positions of the positive electrode end 34 and the negative electrode end 35. Next, extend the third electric cylinder 31 and the fourth electric cylinder 32. Before the potato seedlings undergo low temperature, make the positive electrode end 34 and the negative electrode end 35 contact the potato seedlings and discharge a weak current into the potato seedlings to detect the conductivity of the potato seedlings. Or insert the negative electrode end 35 into the seedling raising pot to detect the conductivity of the roots of the potato seedlings. After the potato seedlings undergo low temperature, repeat the above steps to detect the conductivity of the potato seedlings. By comparing the results of the two detections, judge the cold tolerance of the potato seedlings. And after the potato seedlings undergo low temperature, turn on the first motor 9 to drive the support seat 8 to rotate to adjust the angle of the potato seedlings. Slide the camera 38 on the third track 36 to adjust the position of the fourth electric slider 37. Then, take a picture of the potato seedlings through the fourth electric slider 37. Next, receive the image taken by the fourth electric slider 37 through the data receiving module. Then, perform denoising and grayscale removal on the image through the data preprocessing module. After that, use a convolutional neural network in the data analysis module to analyze and process the preprocessed image to judge the cold tolerance of the potato seedlings. Then, store the image data and the analysis results through the data storage module. Then, the clamping mechanism conveys the identified potato seedlings to the right-side space in the box body 1. Extend the fifth electric cylinder 45 to lower the conveyor belt 43 and make the top of the conveyor belt 43 lower than the top of the support seat 8. Extend the second electric cylinder 14 to push the seedling raising pot onto the conveyor belt 43 with the push plate 15. Then, turn on the fifth motor 44 to drive the conveyor belt 43 to run and adjust the position of the seedling raising pot to enable the potato seedlings that have undergone cold tolerance identification to continue growing in the right-side space in the box body 1. At the same time, take pictures of the growth process of the potato seedlings through the camera to facilitate the staff to judge the cold tolerance of the potato seedlings after low temperature, thereby improving the practicability of the equipment.
