Abstract: Mechanized planting is one of the key technical links in the efficient production of sweet potato. The realization of mechanized planting of sweet potato is of great significance to reduce labor intensity and improve planting quality and efficiency. This paper analyzes the current development status of mechanized technology and equipment for sweet potato planting both domestically and internationally, focusing on the research status and progress of key technologies and equipment of sweet potato chain （band） clip type, multi-link rod type, flexible disk type and other transplanting institutions. This paper mainly introduces the distribution characteristics of the main sweet potato production areas and the agronomic requirements for sweet potato planting. This paper analyzes the development status of sweet potato planting mechanization technologies and equipment at home and abroad. This article focuses on the working characteristics, research focus, and application fields of sweet potato chain （belt） clip-type, multi-link type, flexible disc type and other transplanting mechanisms. This article points out that the existing key technologies and equipment for mechanized sweet potato planting are faced with problems such as low level of sweet potato transplanting machinery, insufficient innovation in key technologies, lack of mature and applicable models that meet the agronomic requirements of sweet potato planting, and lack of automated and intelligent operation equipment. This paper proposes suggestions such as strengthening basic theoretical research, breaking through key technologies, researching diversified technologies and equipment for sweet potato transplanting, and conducting automation and intelligent research, so as to provide reference for the innovative design of key technologies and equipment of sweet potato planting mechanization.
