Wine grape industrialized hard-twig graft seedling cultivation method

The invention discloses a wine grape industrialized hard-twig graft seedling cultivation method. The method includes steps: S1, seedling collection and storage; S2, seedling treatment; S3, a process of selecting stock and graft twigs uniform in thickness, adopting a Germany omega one-time forming graft machine for grafting, and quickly dipping a graft union in molten union wax solution to seal the graft union, wherein the wax solution temperature is kept in a range of 76-80 DEG C; S4, electric hot bed based root growth promotion; S5, greenhouse seedling cultivation. The method is simple and easy in operation, time saving and land saving are realized, cultivation of more than 1,500,000 grafted seedlings per hm can be realized, graft union combination is superior to that of traditional hard-twig grafting, seedling cultivation cost is lower than that of traditional graft seedling cultivation, cold resistance and drought resistance of seedlings can be improved by greenhouse seedling hardening, high seedling quali
