Abstract: Seedling planting quality directly affects the yield of vegetables.Seedling planter with high seeding quality and stable operation is the need for modern agriculture development.Taking YM-0913 type seedling planting machine as the research object，planting experiments of eggplant and bell pepper were made.Results showed that eggplant seeding single grain index was 92.13%，loss index was 4.86% and replay index was 3.01%.Bell pepper seeding single grain index was 94.91%，loss index was 3.94% and replay index was 1.16%.This seeder met the seed diameter ＜5 mm needs.Through changing different specifications suction nozzle，it could expand the sowing of vegetable varieties.YM-0913 type seeder would have a broad application prospect in plant facilities in the park scale breeding.
