Embodiment 1
[0029] see Figure 1-2 As shown, the present invention provides a kind of technical scheme: a kind of two-stage grafting method of multi-color magnolia, and described two-stage grafting method specifically comprises the following steps:
[0030] 1). Select the scion: choose the first scion on the adult purple magnolia that is free from diseases and insect pests and grows vigorously. The scion has 3 to 5 plump, large, and pest-free spores. Keep some young leaves and petioles, and remove them. Old yellow leaves, the thickness of the scion is 1.5-2.0cm, and the length is 5-8cm. Split the scion from the middle, continue to cut off part of the xylem at the bottom of the scion, and cut the bottom of the scion into beveled edges. Apply a mixed solution of 80-100mg / L indoleacetic acid and naphthaleneacetic acid on the place, seal it with plastic wrap, and store it cold at 15-20°C;

Abstract
The invention discloses a two-stage grafting method for multicolor magnolia denudata. The two-stage grafting method specifically comprises the following steps of selecting the current growth shoots ofadult purple and yellow magnolia denudata as scions, cutting to form a groove, and cutting edges after splitting; selecting 1-2-year-old shoots of adult white magnolia denudata as rootstocks, flattening the rootstocks through cutting, and then cutting to form bulges on the rootstocks to cooperate with the scions; firstly combining the scions, applying an auxin mixture, putting the scion groove onthe bulges on the rootstocks, wrapping with preservative film, wrap with a wet gauze, using a cable tie for bundling, after wounds are healed and spores and tender leaves are grown, removing the preservative film, and conducting some post-treatment to obtain the two-stage grafted multicolor magnolia denudata; the method grafts the magnolia denudata with a variety of colors onto a monochromatic magnolia denudata tree, which not only enhances the ornamental value of the monochrome magnolia denudata, but also develops the market potential, excellent traits and plants remains, the multicolor magnolia denudata blossoming in advance is promoted, the economic potential is improved, and the method is conducive to the popularization of the magnolia denudata.
