Research Progress on Key Technology and Equipment of Potato Mechanized Harvest

In China, potato planting area is large and the scope is wide, and artificial harvest has high labor intensity and high cost. Mechanized harvest is the inevitable direction of potato industry development, and also the key technical link in the whole mechanized potato production. The mechanized potato harvest mainly includes the key technologies such as seedling removal, excavation, separation, screening and transportation. In this paper, the development status and characteristics of potato mechanization harvesting technology at home and abroad were analyzed, and the key technologies in potato mechanization harvesting were summarized. The research status of potato harvesting equipment at home and abroad was summarized and the performance parameters of representative models of potato harvesting equipment at home and abroad were introduced. It is pointed out that low loss, high efficiency and intelligent large-scale combined potato harvesting technology and equipment are the core development direction of potato mechanized harvesting technology and equipment in hilly areas.
