The invention discloses a seeding and furrowing integrated device. The seeding and furrowing integrated device comprises a seeding box, a base, a seed box, a seed rotating wheel and a furrower. The seed rotating wheel is arranged in the seed box to driven the seed box to rotate, the seed box is internally and symmetrically provided with a plurality of one-way seed inlet holes, and one side of the bottom of the seed box is provided with a seed outlet hole. The furrower is arranged at the bottom of the seed box and comprises a metal frame, a plough share, a V-shaped scribing blockand a group of flared earth-up plates. Due to arrangement of a curved arc blade, seeds are easy to fall down, so that seeding omission is avoided, and great seeding effects are achieved; owing to the waved seed inlet holes, the seeds are enabled to enter easily, and seeding omission is avoided; by a soft brush which protects the seeds from breakage, the germination rate and survival rate of the seeds are high, and secondary seeding is avoided; owing to separate performing of furrowing and scribing, gradient deformation of soil is realized, great forming effects and less proneness to collapse are realized, repetitive operations of secondary furrowing are avoided, and high efficiency and low labor intensity are realized; due to twice earthing up, soil is softer and loosened well, so that low seed groundbreaking pressure, high germination rate, great seeding effects and high production yield are achieved.
