Description

Technical Field

[0001] The invention relates to the technical field of seed germination devices, in particular to a cultivation device for seed germination experiments. Background Art

[0002] Sorghum is an annual herb of the genus Sorghum in the Poaceae family, with aliases such as milo, reed sorghum, and black grass. Sorghum stalks are thick and erect. The leaves are linear to linear-lanceolate, dark green on the surface, light green or with white powder on the back. The panicles are loose, the main axis is exposed, and the peduncle is erect or slightly curved. The caryopsis is flat and convex on both sides, light red to reddish brown, with the top slightly exposed. The flowering and fruiting period is from June to September. When calculating the germination rate of sorghum seeds, it is necessary to place the seeds in culture solution or culture medium for culture, and observe the germination rate and short-term growth of sorghum seeds in the same environment, so as to facilitate the selection of sorghum seeds suitable for planting in this area.

[0003] In order to supplement nutrition conveniently, the existing seed germination culture usually directly uses culture solution to culture the seeds. For example, Chinese patent announcement number CN218353111U discloses "a kind of plant seed germination", which is provided with a plate body, small holes and a sliding device. The user fits the sponge plate with the plate body, so that the second absorbent cotton is engaged with the small hole, and the large hole is engaged with the first absorbent cotton. The user then starts the sliding device to adjust the height of the dispersion device inside the fixed groove according to the different stages of seed germination. At the same time, the user puts one seed in the small culture groove and two or more seeds in the large culture groove, so that the user can culture seeds in different states at the same time, and effectively avoids the accumulation of cultured seeds in the area to affect the germination of seeds and the counting and calculation of the germination rate of seeds after the seeds germinate, and reduces the workload of the experimenter. However, in actual use, some seeds, such as sorghum and corn, germinate and grow relatively high, and require deeper culture dishes for cultivation. At the same time, they absorb more nutrient solution, and a large amount of nutrient solution needs to be stored for easy absorption. The nutrient solution is prone to breed algae after being exposed to light in the environment, and some effective substances in the nutrient solution will react, causing the nutritional content of the nutrient solution to be different from expectations.
