China has a large geographical area and a diverse agricultural variety. To withstand drought, cold, diseases, and pests, reduce field crop growing period, boost yield per unit area, and develop high-yield and effective agriculture, seedling growing and transplanting are crucial. Mechanized transplanting is a key technical link in crop mechanized production. Its technology does reflect the level of mechanization and modernization of agricultural production. That being so, the current state of research and development of mechanized transplanting technology and equipments for field crops in China and abroad was summarised, the structures and types of automatic seedling picking and planting equipments used in transplanters in China and abroad were analysed and summarised, and the working principle and structural features of diverse transplanting technologies and mechanisms were explained. The cornerstone of transplanting equipment innovation was transplanting mechanism innovation, and mechanism synthesis lied at the heart of mechanical transplanting mechanism innovation. The current state of transplanting mechanism configuration research and the dimension synthesis approach were discussed. Finally, the issues that risen in China’s development of mechanized transplanting technology and equipments were examined, and suggestions for future development were made. It was stated that efficient, precise, and reduced failure of seedling picking and planting technologies and mechanisms were important indications for automatic transplanting in paddy and dry fields, and that efficient automatic transplanting technologies and equipments based on information and intelligent technologies were an important direction for the future development of mechanized transplanting technology.
