Abstract: The traditional south-north ridge planting method in sunlight greenhouse has many short ridges. The space of greenhouse is narrow, so there are many problems in agricultural machinery operation, such as difficulty of adjusting direction, entering the door, walking on the road, and ploughing on the side. To adapt  the development of mechanization, a new mechanized planting mode is needed. Taking pepper as  research object, this paper studied crop traits, yield, fruit and other parameters under the two modes of mechanical east-west ridge planting and artificial north-south ridge planting to explore the feasibility of mechanical planting mode. The results showed that transplanting depth of 6 cm, row space of 30 cm and plant space of 40 cm were the best working parameters of the transplanter. The plant heights of artificial mode were 4.1% and 3.95% higher than that of mechanical mode at 35 and 70 d, while the stem diameters of mechanized model was 5.72% and 3.63% higher at 35 and 70 d. The difference was significant between them. However, the difference between the underground part of the two modes was small, while the accumulation of the mechanized part of the above ground was high and the characters were reasonable. The effective yield of mechanical mode was 2.38 t, which was 11.21% higher than that of artificial mode. The two planting modes had the same nutritional composition and different contents. Therefore, the mechanical planting mode had certain advantages over the artificial planting mode and it could be used in  sunlight greenhouse for pepper production.
