摘要:
A precision seeder for sowing seeds to obtain a predetermined number of plants per unit of length comprises a seed discharging tube (13) adapted to feed said seed by means of an excess air pressure from a seed distributing device (11) to a seed outlet (14), a seed furrow opener (15) comprising two sowing discs (15a, 15b) arranged at an angle relative to each other, and a resilient press surface (16) for pressing the seed into the soil. The press surface (16) is designed such that a direction of flow (F) of the seeds at the seed outlet (14) intersects or is substantially tangent to at least a portion of the press surface (16). The seed outlet (14) is located between the sowing discs (15a, 15b) and, as seen in the transverse direction, inside or immediately adjacent to the periphery of at least one of the sowing discs (15).
