To address problems caused by rice machine transplanting such as injury to the seedlings and recovery period that extend growth period, this study explored the effects of different machine transplanting methods on the physiological and yield characteristics of late rice in China, and determine the appropriate machine transplanting method for late rice, which was expected to provide a basis for high-yield and high-efficient cultivation of machine-transplanted late rice. Hybrid indica rice Taiyou 398 and conventional indica rice Jing Gangruanzhan were selected as the research objects, and large-pot carpet seedling machine transplanting (M1), conventional pot carpet seedling machine transplanting (M2) and ordinary carpet seedling machine transplanting (M3) were adopted respectively to analyze their effects on seedling quality, population physiological characteristics, yield and its components and economic benefits of late rice. The results showed that compared with M2 and M3, M1 achieved higher seedling quality, showing significant advantages in the early stage despite average root entwining force that met the requirement of machine transplanting. The seedlings transplanted using M1 had shorter recovery period after mechanical transplanting, with earlier tillering, earlier peak seedling, and slower declining of stems and tillers in the late stage; the peak seedling number was not high, but the effective tiller number and earbearing tiller percentage were significantly higher than those achieved by the other two machine transplanting methods. Also, M1 achieved stronger photosynthetic capacity of flag leaves before HS, with more photosynthetic products in stems and leaves transported to panicles and more efficiently after HS. Compared with seedlings transplanted using M2 and M3, the recovery period of those transplanted using M1 was shortened by 3 and 5 d, the heading stage (HS), and maturity stage (MS) were advanced, which effectively reduced the risk and impact of "cold dew wind" on machine-transplanted late rice. M1 had significant yield increase advantage and economic benefit, with better grain maturity, and "larger panicles, more panicles, more and fuller grains". M1 achieved an average yield increase of 10.31%-11.10%, 20.67%-25.10% in 2 years, and an average income increase of 18.65%-131.06% and 62.85%-323.78%, respectively. Therefore, vigorously developing M1 is the key to the high-yield and high-efficient cultivation of machine-transplanted late rice in China.

“…The mechanism mainly includes a frame, a crank, a connecting rod, a rocker bar, a cam, a swing push rod, and a seedling clamping device. A swing push rod (2), a cam (3), a crank (4), and a rocker bar (7) are installed on the frame (1). A seedling clamp is installed on the connecting rod, and the angle between the two is 30°.…”

“…At present, the planting methods of sweet potato seedlings mainly include oblique planting, vertical planting, ' boat-bottom' planting, and horizontal planting. Among these, the ' boat-bottom' planting can make sweet potato seedlings have more nodes in the soil [7] , so the percentage of large and medium sweet potatoes in each plant and the average yield are relatively high.…”

“…The small self-propelled clip transplanter produced by ISEKI Co., Ltd. in Japan, is suitable for loose soil operations such as volcanic ash and has poor compaction, especially in areas where the soil is not easily crushed. Therefore, this type of transplanter is not suitable for planting sweet potato seedlings in China [7] . Domestic research on sweet potato seedling transplanting began in recent years and has been at a standstill due to problems such as complex structures, high production costs, and difficulty in coordinating machinery and planting agronomy [19,20] .…”

Planting on mulched soil is the main cultivation mode for sweet potato slips in spring in northern China. The 'boatbottom' planting method can bring high quantity and similar size for sweet potatoes. In this study, a mechanism for transplanting sweet potato seedlings on mulched was proposed, which could realize 'boat-bottom' transplanting trajectory and improve the planting efficiency. The virtual prototype model of the transplanting mechanism was constructed using ADAMS software, a soil particle model and a flexible body model of sweet potato seedling were established using EDEM software, and then a joint simulation was carried out to find out the interaction of mechanism, seedling and soil. By simulation, the trajectory of the clamping point, the sweet potato seedling posture, soil particles, pits, and relative force were all analyzed, which verified the rationality of the transplanting mechanism design. Finally, three kinds of sweet potato seedlings, watermelon red, Yan-25, and purple sweet potato seedlings were selected, and transplanting experiments were carried out on the mulch to verify that the theoretical trajectory, the simulated trajectory, and the actual trajectory were consistent. The transplanting success rates of the three kinds of sweet potato seedlings were all above 85%, indicating that different varieties of sweet potato seedlings had little effect on the transplanting effect of the mechanism, which reflected that the transplanting mechanism had good practicability and adaptability.
