The invention belongs to the technical field of agricultural machinery and discloses a feeding recovery method for tobacco seedling breeding and a feeding recovery all-in-one machine. The feeding recovery all-in-one machine comprises a hopper 2, a material grabbing hopper 3, a chain wheel 4, a chain and a machine frame 1; the parallel power-driven chain wheel 4 and a drum A 5 are arranged at the upper end of the machine frame 1; a drum B 7 capable of turning around the chain is arranged below the power-driven chain wheel 4 and the drum A 5; a drum C 10 for recovering seedling raising base of a breeding machine is arranged on one side of the bottom end of the machine frame 1; a drum D 11 capable of turning around the chain is arranged on the other side of the bottom end of the machine frame 1; the hopper 2 is arranged above the drum D 11; the material grabbing hopper 3 is arranged on the chain; and the chain is wound on the power-driven chain wheel 4, the drum A 5, the drum C 10 and the drum D 11. The feeding recovery all-in-one machine can realize automatic feeding during seedling raising of tobacco leaves and can recover base leaking from the breeding machine and recycle the base automatically; and the invention has the advantages that the work intensity of tobacco growers can be relieved, the feeding efficiency is improved, and the requirement for large-scale and intensive breeding of tobacco leaves can be met.
