The invention discloses a hybrid-driven planetary gear system transmission and orientation transplanting apparatus. No apparatus capable of directionally delivering pot seedlings is discovered. A planetary frame is driven by a constant-speed motor, and a central shaft is driven by a speed-regulating motor; a first intermediate gear makes non-uniform rotation, and a transplanting arm swings in a plane by virtue of variable-speed transmission from a second intermediate gear to a first planetary gear; a second sun gear, a third intermediate gear and a second planetary gear are engaged to transfer the power to a first bevel gear in the transplanting arm, and a second bevel gear engaged with the first bevel gear drives a transplanting claw to rotate by virtue of a transplanting shaft; the first planetary gear rotates relative to the planetary frame, so that a conjugate cam formed by a first cam and a second cam transfers the power to a seedling pushing rod by virtue of a roller, a connecting member and an oscillating rod; and seedling pushing blocks of the seedling pushing rod clamp or release two leaf springs of the transplanting claw so as to clamp or plant the seedlings. By adopting the hybrid-driven planetary gear system transmission and orientation transplanting apparatus, the self-adaptive adjustment of an azimuth of the pot seedling can be realized.
