Abstract: Potato stem and leaf silage technology and feed utilization are the main ways to promote the upgrading of potato industry and the realization of the resource-based and efficient utilization of agricultural waste, which is also the key technical point of potato mechanization in the whole process. In this paper, the research progress and development trend of potato stem and leaf silage harvest was systematically analyzed through the comparison of different operation methods and different operation machines and tools in the links of seedling cutting, picking, chopping, harvesting, baling and coating of potato stem and leaf silage point at the present condition of potato stem and leaf silage in China. It was proposed that the key to promote rapid development of mechanized harvesting of potato stem and leaf silage was to improve the technical system, improve the research and development of machines and tools, improve the degree of mechanical automation. This will provide a reference basis for further development of potato stem and leaf silage related machine.
