Embodiment 1

[0016] Hybridization method: a new variety Mengxing was obtained by crossing Lechang Michelle as the female parent and Zihua Michelle as the male parent.

[0017] In 2003, Lechang smiled ( Michelia chapensis ) is the female parent, and Zihua smiles ( Michelia crassipes ) as the male parent to obtain the new variety Mengxing. In 2003, half-bloomed flowers were collected during the full flowering stage of Michelia japonica, the stamens were picked off, the anthers were naturally split at room temperature, pollen was released, the pollen was collected and dried at low temperature; When the tepals are not yet fully opened, gently pull the tepals, remove the stamens, pollinate them with fresh or stored pollen of Michelia chinensis, and quickly restore the tepals to wrap the pistil group, bag them, put them on a tag, and remove the bags after 7 days; 9- In October, when the color of the follicles turns dark red, pick the fruits and place them in a ventilated room. After crack...
