Description

Technical Field

[0001] The utility model relates to the technical field of automatic direct seeding of rice, in particular to a direct seeding device for rice. Background Art

[0002] Direct seeding of rice is an agricultural planting method that refers to directly sowing rice seeds without going through the seedling stage.
