Potato full-procedure integrated seeder and seeding method thereof

The invention discloses a potato full-procedure integrated seeder and a seeding method thereof, and belongs to the field of agricultural machinery. The problem that a potato seeder is uneven in soil covering, cannot be used for shaping ridge bodies and cannot be used for carrying out ridge-body imitating mulching is solved. The potato full-procedure integrated seeder comprises a rotary tillage andridging device, a ridge shaping and seeding device, a ridging film soil covering device and a ridge-body imitating mulching device; the ridging film soil covering device comprises two soil covering units which are oppositely arranged; each soil covering unit comprises a soil lifting shovel, a rotating shaft, a disc and soil throwing blades; and in each soil covering unit, the disc is convex and protrudes inwards, the soil throwing blades are uniformly distributed on the inner side of the disc in the radial direction, the soil throwing blades incline downwards along the axial direction of therotating shaft, an outer s
