Abstract

The invention relates to a rapid culture method for magnolia grandiflora and belongs to the technical field of plant grafting. The method comprises the following steps: carrying out rootstock culture: culturing Magnolia denudata as rootstock at the last ten days of March, and carrying out disinfecting and fertilizing treatment on culture seedling beds; carrying out grafting preparation: carrying out grafting at the second or third 10 days of March; carrying out graft selecting: selecting annual magnolia grandiflora branches as grafts; carrying out a grafting process: smearing rootstock incisions and graft faces with a disinfecting and growth-promoting solution during grafting; carrying out grafting management: shading grafted seedlings with shading nets after grafting is completed, removing binding films when the length of each grafted graft bud reaches 20cm, and carrying out top application with a compound fertilizer; and carrying out transplanting management: transplanting the grafted seedlings out of gardens after the grafted seedlings are cultured for 2 years. The rapid culture method for the magnolia grandiflora, provided by the invention, has the advantages that the survival rate of the grafted seedlings is high, and the growth speed is high.
