There are multiple limiting magnetic blocks 500 in the limiting grooves 421, and a seed receiving groove for storing a single seed is formed between two adjacent limiting magnetic blocks 500.

[0038] The limiting groove 421 serves to limit the position of the limiting magnetic block 500. Since the length of the limiting groove 421 and the length of the sowing roller 420 are parallel to each other, a seed receiving groove for storing a single seed is formed between two adjacent limiting magnetic blocks 500. Therefore, the seed receiving grooves in the same limiting groove 421 are in the same straight line. That is, when the sowing roller 420 rotates, each row of seed receiving grooves can transfer the seeds in the sowing bucket 410 out of the discharge port 411, and then sow rows of seeds on the seedling tray 200, and finally sow a seed in each seedling groove of the seedling tray 200.
