Abstract: There are many kinds of small seed crops in China，and the planting area is extensive.But it is difficult for precision seeding because of its small size，light weight and irregular shape of some seeds.Research status of precision seeder for small seeds at home and abroad was described.Current characteristics and existing problems of China′s precision seeder for small seeds were summarized.Based on these，development trend and direction of China′s precision seeder for small seeds were pointed out.It provided reference for study of precision seeder for small seeds.
