In the process of mechanized harvesting of root crops,problems such as large working resistance and serious harvest damage are often encountered,which affect the harvest efficiency.Research on methods to reduce excavation resistance and harvest damage during mechanized harvesting of root crops can improve the harvest effect,help to improve the overall level of agricultural mechanization in China,and promote the balanced development of root crop industry in the country.This paper introduces the research status of low-resistance and low-loss harvesting technology for root crops at home and abroad,analyzes and compares the working principle,characteristics and performance of the existing low-resistance and low-loss harvesting machines and tools,explores the low-resistance and low-loss harvesting methods of rhizome crops,and makes prospects for the problems existing in the current research.The above research can theoretically expand the research methods of the harvesting mechanism of rhizome crops with low resistance and low loss,which is directly related to the development of the national economy in practical application,and has important scientific significance and application value.
