Description

Technical Field

[0001] This utility model relates to the field of corn seed germination technology, and more specifically, to an experimental device for corn seed germination. Background Technology

[0002] Corn is an important food crop, with the largest planting area and highest total yield in the world. With the global population growing and food demand rising, ensuring corn production is crucial for food security. The uniformity of corn germination is a key factor in ensuring overall productivity. Seed germination rate refers to the percentage of normally germinated seeds at the end of a germination test under specified conditions and time. To ensure the maximum germination potential of corn seeds and compare the quality of different corn seeds, germination experiments are necessary.

[0003] Traditional experiments require manual sowing, trenching, covering with soil, watering, etc., which is inefficient. Furthermore, manual sowing makes it difficult to maintain uniform spacing and precise control of depth, and it is impossible to ensure consistent experimental conditions for the same batch, which affects the germination rate measurement results. Therefore, a maize seed germination experimental device is proposed. Utility Model Content

Then, start the first motor 8 and control the second motor 20 to start, so that the seeds inside the seed box 6 fall into the middle of the discharge pipe in sequence. At the same time, the trenching plate 15 opens trenches in the soil, and the seeds fall into the trenches. Then, the soil covering plate 16 is used to cover the soil, and the sowing of the seeds is completed.

[0038] After sowing is completed, control the electric push rod 13 to drive the lifting plate 10 to move the furrowing plate 15 and the soil covering plate 16 out from the middle of the seedling box 5, and then control the first motor 8 to drive in reverse to control the seed box 6 to reset in sequence.

[0039] When water needs to be added during seedling experiments, liquid is injected into the water plate 2 and sprayed evenly onto the center of the seedling box 5 through the nozzle 3, thus achieving automatic water replenishment. Excess liquid will be automatically discharged through the drain pipe 22 at the bottom of the positioning groove 4.
