[0055] Furthermore, because the movable detection rod 506 is slidably mounted on the circular ventilation pipe 301, and the detection button 507 is fixedly mounted on the front side of the movable detection rod 506, and the arc-shaped force-bearing block 508 is fixedly mounted on the front side of the detection button 507, when the transparent roll 504 is in the winding state, the transparent roll 504 can press the detection button 507 through the arc-shaped force-bearing block 508; when the transparent roll 504 is not in the winding state, the transparent roll 504 cannot press the detection button 507 through the arc-shaped force-bearing block 508; and because of the control...

Next, the external temperature control module, humidity control module, and water / fertilizer addition module are installed in the breeding shell 100, and electrically connected to the controller 600. Then, the controller 600 controls the motor 503 to move the transparent roll 504, which in turn moves the circular solid rod 505 upwards. The soil and the corn to be cultivated are placed in the five movable planting boxes 202. The controller 600 then controls the motor 503 to move the circular solid rod 505, which in turn moves the transparent roll 504 upwards. The transparent roll 504 moves downwards; when it is in the retracted state, it can press the detection button 507 through the arc-shaped force block 508; when it is not in the retracted state, it cannot press the detection button 507 through the arc-shaped force block 508; when the detection button 507 is pressed and the four electric telescopic rods 203 or the fan 304 are working, the alarm in the controller 600 will sound an alarm, prompting the staff to close the transparent roll 504 in time; when the detection button 507 is not pressed and the four electric telescopic rods 203 or the fan 304 are working, the alarm in the controller 600 will not sound an alarm.

When the output shaft of the right electric telescopic rod 203 extends, the two movable planting boxes 202 on the rear slide to the left. When the output shaft of the front electric telescopic rod 203 extends, the movable planting box 202 on the right slides backward, allowing the five movable planting boxes 202 to rotate within the rectangular outer shell 201. This changes the position of the corn being cultivated, allowing it to contact different positions within the selection shell 100, thus improving the accuracy of the cultivation. When the output shaft of one of the electric telescopic rods 203 extends, the water in the gaps is squeezed out, allowing excess water to enter the two adjacent movable planting boxes 202 through the two connecting slots 2021, which is beneficial to the cultivation of the five movable planting boxes 202. The soil absorbs bottom moisture; the controller 600 controls the intermittent operation of the solenoid valve 303 and the fan 304. When the fan 304 is working, externally filtered air can enter the breeding shell 100 through the circular ventilation pipe 301; when the solenoid valve 303 is open, carbon dioxide gas, under the action of the fan 304, can enter the breeding shell 100 along with the external air, which is beneficial to improving the growth effect of corn seedlings; when the fan 304 is working, under the action of gas pressure, the movable sealing frame 403 will slide downward, allowing the gas in the circular ventilation pipe 301 to enter the breeding shell 100 through the gap between the circular ventilation pipe 301 and the movable sealing frame 403. The gas in the breeding shell 100 is discharged through two rows of exhaust holes 101, realizing automatic ventilation in the breeding shell 100. At the same time, carbon dioxide can be added periodically according to the cultivation situation; when the fan 304 stops working, the movable sealing frame 403 automatically returns to its original position under the action of the return spring a405, achieving a sealing effect.
