An automatic seedling pick-up and seedling feeding device for a transplanter, comprising a seedling pick-up mechanism (1), a seedling guide device (2), a transfer mechanism (3) and seedling separating mechanisms (4), the seedling pick-up mechanism being mounted above the transfer mechanism, two seedling separating mechanisms being symmetrically provided on two sides of the transfer mechanism, the seedling guide device being fixed above the seedling separating mechanisms. The transfer mechanism transports the plug seedlings to a seedling pick-up point, the seedling pick-up mechanism moves each seedling pick-up claw (1-11) to the seedling pick-up point to pick up seedlings, and to a seedling feeding point to feed seedlings, the seedling guide device enables a seedling pot to enter the seedling separating mechanism according to a predetermined trajectory, and the seedling separating mechanism transfers, in a rotated manner, the pot body to a seedling drop-off point to drop seedlings. The device realizes continuous seedling pick-up in rows, and synchronous seedling feeding, improving the seedling pick-up efficiency, the seedling feeding efficiency and the success rate； furthermore, the plug tray only needs to perform a longitudinal transport motion, improving the transport efficiency of the plug tray. The seedling pick-up claw needle, before being inserted into the pot body, has a function of sorting the seedlings, improving the quality of the picked seedlings. The seedling guide device receives the seedlings in a stationary manner, shortening the distance of free-fall motion, enabling precise seedling feeding.La présente invention concerne un dispositif automatique de ramassage de semis et d'alimentation en semis pour une repiqueuse, comprenant un mécanisme de ramassage de semis (1), un dispositif de guidage de semis (2), un mécanisme de transfert (3) et des mécanismes de séparation de semis (4), le mécanisme de ramassage de semis étant monté au-dessus du mécanisme de
