Abstract: The Bashang area of Zhangjiakou has formed its own mechanized production mode for openair headed leafy vegetables, including mechanized agronomy and supporting agricultural machinery and equipment. However, synchronous mechanical ‘sealing’ cannot be achieved during mechanical transplanting, and ‘sealing’ still needs to be completed manually, resulting in chain scission in mechanization of transplanting, which restricts the development and realization of full mechanization. In view of the above problems, this study proposes to adjust the mulch film ‘sealing’ process problem that cannot be solved by the transplanting machine after transplanting to the ridging process before transplanting to solve the ‘soil sealing method and technology of mulch film mouth after machine transplanting’. Through the optimization and improvement of a variety of ridging film mulching machines, an active film mulching ridging machine supporting this technology has been successfully developed. The test showed that the qualified rate of ‘sealing’ of seedling holes after transplanting could reach more than 98%. The technical scheme and supporting equipment formed in this study complement the mechanized chain breaking in the transplanting process, which can basically realize the full mechanization of heading leaf vegetables in Bashang area. At the same time, it can also be used as a common technology and equipment for mechanized transplanting of openfield vegetables on film to demonstrate and promote in the whole country, so as to improve the mechanization level of Chinas vegetable industry.
