Abstract: With the continuous development of lotus root industry in China, the mechanized harvesting technology of lotus root has been paid more and more attention in China. The development of reliable lotus root harvesting machinery has become the most important part of the modernization process of lotus root industry in China. Therefore, this paper summarized and analyzed the characteristics and harvesting requirements of lotus root plants, compared and analyzed the lotus root harvesting machinery at home and abroad, summarized the types, advantages and disadvantages of lotus root harvesting machinery in China, listed the representative research and development achievements of lotus root harvesting machinery in China, and pointed out that the planting mode of lotus root was not uniform in China. The problems of low degree of automation and single mechanical structure and function of lotus root harvesting machinery were put forward. Combined with Chinas national conditions, some development suggestions were put forward, such as standardizing the regional standardized planting mode of lotus root, formulating the standard requirements of lotus root harvester and increasing the research on key technologies of lotus root harvesting machinery, so as to provide reference for the further development of lotus root harvesting machinery.
