The current cultivation of apple trees mainly relies on grafted seedlings to achieve seedling regeneration of apple trees. The commonly used splice grafting, V-shaped grafting and tongue grafting mostly use plastic film for fixation and sealing. After one year, the wrapped plastic film needs to be removed to avoid affecting the growth of the seedlings. This paper introduces a brand new grafting technology which uses tongue grafting iron nails for fixation and growth fixation wax for sealing (SDRG). The process of mechanized grafting for apple nursery stock is determined, and the fixation and sealing problems with the grafting parts of seedlings are solved. The technology is characterized by quick speed, high efficiency, improved seedling survival rate lower labor cost and great significance to the promotion of industrialized nursery and mechanized grafting.
