Abstract

The invention discloses a method for grafting large branches of Camellia japonica, comprising the following steps: (1) selection of stock; (2) selection of scion; (3) treatment of stock; (4) treatment of scion; (5) grafting: scion embedded in stock In the "V" groove, the two sides are closely connected. Tie the joint tightly with thin iron wire, and make the excess part face down, then wrap the joint with film, and wrap the scion with film at the same time. The plastic film does not Completely wrap the excess iron wire so that the interface will not accumulate water and at the same time keep it breathable; (6) Manage after grafting. The invention improves the grafting survival rate of camellia camellia, promotes the growth and flowering of scions, shortens the cultivation cycle of large-scale plants, and has a good role in promoting the development of camellia camellia industry.
