摘要：
A row unit for a seeding machine includes a seed reservoir and a seed meterhaving a meteringmember with a seed side facing the seed reservoir, a non-seed side oppositethe seed side, and aplurality of apertures. The seed meter is operable by pressure differentialbetween the non-seedside and the seed side to adhere seeds to the seed side and move seeds fromthe seed reservoir. Aconduit has a venturi with a throat disposed adjacent the metering member. Thethroat presentsan opening directed toward the seed side and the plurality of apertures. Theopening isconfigured to receive a seed adhered to one aperture of the plurality ofapertures. An air pressuresource is configured to provide greater than atmospheric air pressure on thenon-seed side suchthat during operation of the row unit an air stream passes through the oneaperture toward theopening.
