Result 2TYB-450 rice seedling seeder adopted the synchronous driving wheel, the equipment for vibrating and homogeneous sowing and the guiding sowing plate with seed box cross, so it didn't slip when driving and had high eligible ratio of sowing, good effect of filling seeds, less sowing seed number per seedling area and high working stability, with the sowing eligible ratio of 68.67%, the sowing blank-hole ratio of 1.89% and the sowing seed number per seedling area of 4.19. The working performance of 2FBS-840 seeder was next and that of MR-BZ840A seeder was worst.
