Abstract

The application discloses a method for grafting magnolia denudata with magnolia grandiflora, and belongs to the technical field of plant grafting and maintenance. The method for grafting magnolia denudata with magnolia grandiflora is characterized by using magnolia denudata as a stock, using a branch of magnolia grandiflora as a scion, adopting the bud-embedding grafting method, and combining with field water and fertilizer management in the later period to obtain the grafted plant. In the second year after grafting, a special spraying agent for magnolia grandiflora is sprayed. The grafting method is simple in process, and the survival rate of grafting is above 70% by selecting a suitable magnolia denudata stock, a suitable magnolia grandiflora scion, a suitable grafting time and a correct grafting mode, so that the propagation efficiency of magnolia grandiflora seedlings is greatly improved, and large-scale seedling raising of magnolia grandiflora can be realized, with low cost and high benefit. After the spraying agent is used, the number of flowers and the quality of flowers of magnolia grandiflora can be effectively improved, the spraying agent is convenient to use, is mild and safe, and the flowering ornamental property of magnolia grandiflora is improved.
