FIELD: agricultural engineering. SUBSTANCE: seeding unit has horizontal rotary shaft equipped with drive and immovably fixed casing positioned so as to embrace said shaft and provided with upper and lower openings. Lower opening is connected to seed guide. Partition wall is fixed on shaft for providing periodic communication between casing cavity and seed guide through lower opening. At least one ejector and counterweight are fixed on partition wall. Casing lower opening is formed as shaped dosing slot. Shaft is positioned for effecting reciprocating vibratory rotations at predetermined frequency within the range of 50-200 Hz and vibration amplitude of 1-50 deg for forming fluidized bed for seeds.
