The utility model relates to a seeding part and corresponding seeder, the system of burying (5), depth control device (6), closing device (7), rolling wheel (15) and closed dish (16) are installed including support (2) to seeding part (1) on the support, and rolling wheel (15) and closed dish (16) extend between the system of burying (5) and compaction device (7). The characterized in that of seeder (1), rolling wheel (15) and closed dish (16) are fixed on public articulated elements (20) that have the horizontal axis. Seeder (30) distribute in the frame including frame (31), at least one seeding part (1). Borrow this, compaction and the closure of furrow improve, because of the seed drop a little and the compaction device between the distance shorten, utilize shorter seeding part, even also obtained the assurance to the cover of furrow in the curvilinear figure seeding, favorable is that the constitution component quantity of seeding part reduces.
