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.

摘要： 日光温室传统的南北垄向种植方式垄数多且垄长短，温室内空间狭小，农机作业时存在‘头难调、门难进、路难走、边难耕’等诸多问题，为了适应机械化发展，需要一种新的种植模式。以辣椒为研究对象，通过比较移栽机东西垄向与人工南北垄向种植模式下作物的性状、产量、果实等参数，探讨机械化种植模式的可行性。结果表明：移栽深度6 cm、行距30 cm、株距40 cm为移栽机的最佳作业参数；人工模式辣椒株高在35、70 d时高出4.1%和3.95%，机械化模式茎粗在35、70 d时高出5.72%和3.63%，差异较为显著；两种模式地下部分差异较小，地上部分机械化模式积累量较高，性状较为合理；机械化模式有效产量为2.38 t，比人工模式增产11.21%；两种模式下的辣椒营养成分组成相同，含量各有优劣。机械化种植模式对比人工种植模式存在一定优势，可以在日光温室内采用该模式进行辣椒的生产。
