Abstract: As one of China's important economic crops, green onion has the world's largest planting area and yield．Green onion industry in China is currently undergoing an important transformation from traditional field seedling cultivation model to factory-intensive seedling cultivation and planting model．At present, most of mechanical equipment used for intensive green onion seedling cultivation and planting is vegetable universal machinery, mainly using mechanical suction-type seeders．There are relatively few specialized seedling cultivation and planting technologies and equipment for green onions, which have not been able to solve problems such as precise seeding, missing seeds, and seed injury during onion seeding．To accelerate development of green onion planting mechanization, research progress of domestic and foreign green onion seedling cultivation and planting machinery wass being collected to provide a certain reference and guidance for development of green onion precise seeding and seedling cultivation technology and equipment in China．
