The seeding device is produced with the main structure as a carrying tube (1), which is closed at each end, and has planting tubes (2)suspended down from the body of the main tube. The lower ends (7) of the planting tubes are shaped as an inverted cone and are pierced through the central axis. Mounted above the main tube and feeding into it, is the injector (4), which is linked through a valve control to the air circuit (5), to supply the motive force to carry the seeds.
