Abstract: The mechanized transplanting of sweet potato is the weak link of the current mechanized sweet potato planting. Due to the physical characteristics such as stem bending and group entanglement which may occur during the growth of sweet potato seedlings, the technology of dividing seedlings and taking seedlings during the transplanting process has become a key problem which restricts the design and development of automatic sweet potato transplanters and needs to be solved urgently. This paper expounds the research status of sweet potato seedlings and harvesting technology at home and abroad, analyzes the problems existing in the sweet potato automatic transplanters currently in use, such as too high manual participation, few special devices for sweet potato seedling and great regional differences. This paper puts forward the relevant suggestions and countermeasures, such as establishing the standard of sweet potato seedling raising and cutting, refining the transplanting process, strengthening the application of visual identification and information technology, for the development direction of sweet potato automatic seedlings and harvesting technology.
