[0054] The germination status of corn seeds can be detected by the detection camera 231. Since there is only one corn seed in each planting circle 304 and the planting circles 304 are arranged neatly, it is easy to calculate statistics. Different corn seeds can also be placed in each germination tray 205 to detect the germination status of corn seeds under the same environment, thereby expanding the detection range of the device.

[0055] The germination test component 2 can simulate the temperature difference between soil and air in different environments as needed, so that the germination test is closer to the germination conditions in different natural environments. The germination auxiliary component 3 is used in conjunction with the germination test component 2. The heat conductive strip 301 and the air vent 302 make the heat more uniform. The planting circle 304 and the smoothing scraper 310 are more convenient for the placement and counting of corn seeds, making the test more convenient and easy to conduct, and easy to operate.
