Efficacy of Sweet Potato Transplanting Machine for Different Cultivation Systems in Northern China

China is the world’s biggest producer of sweet potato (Ipomoea batatas (L). Lam.), and approximately 55% global supply from China. Raised beds (RB) raised mulched with plastic film (RBF) are two main cultivation systems now widely used in northern Planting placement multiple nodes buried shallow soil layers additionally required for to achieve higher yields reduce pests diseases this area, which increases difficulty transplanting mechanically. Therefore, a 2CGFS-2 compound transplanter was developed, key parameters slips apparatus were designed paper. Furthermore, its performance investigated over years under four treatments different varieties (Jishu 26 Pushu 32) (RBF RB). The results showed that missing seedling rate qualified population each treatment by using <1.2% >95.0% both 2020 2021, while mean values plant spacing variation coefficient depth during 2020–2021 4.53% 96.28%, respectively. length slip inserted into almost same, ca. 195 mm. accurate reduced differences tuber weight per caused manual transplanting. These considerable importance RB RBF systems.
