The invention discloses a garden seeder for breeding. The garden seeder comprises one frame (1) and a seed case (3) and is characterized in that a plurality of tunnels (9) are evenly arrayed at the bottom of the frame (1), each tunnel (9) is provided with one steel rod (8) capable of being inserting into the tunnel (9) thereon, the length of the steel rod (8) is greater than that of the tunnel (9) and can penetratingly move in the tunnel (9), all the steel rods (8) are joined together through a horizontal pipe (6), and the horizontal pipe (6) is connected with a connecting rod (2) greater than the frame (1) in length through a bend board (10). By the arrangement, row spacing, line spacing and depth are basically assuredly identical in seed sowing of crops, and the garden seeder is simple in structure, easy to operate and high in efficiency.
