Abstract: At present, the problem of adhesion reduction and desorption of soil touching parts of agricultural machinery is still perplexing experts and scholars at home and abroad, which is a technical problem to be solved urgently. In order to provide a reference for the development of adhesion-reducing and desorption technology of soil contact parts of agricultural machinery in China, the causes of soil adhesion in agricultural machinery and the influence of soil adhesion on agricultural machinery operation were systematically summarized. This paper mainly introduces the current research status of adhesion reduction and desorption technology for earth-contact parts of agricultural machinery at home and abroad from five aspects of surface modification, surface modification, electroosmosis, mechanical adhesion reduction, and thermal adhesion reduction. Compared to the research status abroad, it was found that the current domestic agricultural machinery soil contact parts adhesion reduction and desorption technology was lacking comprehensive research on soil adhesion mechanism as well as high accuracy test equipment. It was concluded that the future development direction of the technology was to strengthen interdisciplinary integration, strengthen the research of soil viscosity reduction technology, and strengthen the development of multi-parameter testing equipment. At the end of the paper, the future development direction of the technology is to strengthen the interdisciplinary integration, strengthen the research of soil viscosity reduction technology and strengthen the development of multi-parameter testing equipment.
