Abstract: With development of sweet potato industry, mechanization level of sweet potato production is constantly improving, especially in cultivation and land preparation process, which develops the fastest．However, lack of suitable transplanter has made transplanting process a bottleneck in industrial development．Main types of sweet potato transplanter abroad were briefly described, its homework characteristics and scope of application were analyzed．Existing sweet potato transplanting tools and machinery in China were listed, their respective structural characteristics and applicable planting modes were analyzed．Based on current new domestic agricultural techniques for sweet potato planting, current cutting-edge technology in domestic sweet potato mechanical research was analyzed．Meanwhile, suggestions for research focus and development goals of sweet potato transplanter in China were put forward．
