Abstract: Based on the practice of planting Dioscorea polystachya in Ulan Buh Desert, this paper summarized the key points of mechanized planting technology in Ulan Buh Desert Dioscorea polystachya from the aspects of variety selection, land selection, tillage, sowing, field management, harvest and storage, taking the integration of planting agronomy and agricultural machinery as the technical route, aiming at providing technical support for planting Dioscorea polystachya in Ulan Buh Desert. The restriction factors and bottleneck problems of Dioscorea polystachya planting in Ulan Buh Desert were discussed, and suggestions were put forward to carry out research on the application of Dioscorea polystachya seeding machine, Dioscorea polystachya harvesting machine and biodegradable mulch film, so as to realize the full mechanization and green high quality Dioscorea polystachya planting.
