Abstract

A crape myrtle nursery stock cultivation method includes the following steps that a crape myrtle sapling with the trunk diameter ranging from 1 cm to 1.5 cm and for grafting is cultivated; a crape myrtle trunk with the diameter meeting expected requirements is cut into segments, the two ends of the crape myrtle trunk are sawn flat, and the crape myrtle trunk serves as a rootstock trunk; grafting of a root of the rootstock trunk is conducted; two or more longitudinal wedge-shaped long openings are formed in the lower end of the rootstock trunk, the crape myrtle sapling for grafting is excavated, the root system of the crape myrtle sapling is retained, the trunk and the canopy, above the position, 30-50 cm away from the root portion, of the crape myrtle sapling are cut off, the grafting portion is cut to be matched with that of the wedge-shape long openings in shape, is tied up through a grafting film after grafting, and is reinforced and fixed; the two ends of the rootstock trunk and the grafting portion are respectively coated with a layer of wound plastics, and the portion, 20 cm below the rootstock trunk top end is wound with a layer of protective film; after the above steps, the rootstock trunk with the grafting root is planted in the soil, the rootstock trunk is supported and fixed, a sunshelter is built, and daily cultivation management is conducted; half a year later after cultivation, the protective film is removed, the sunshelter is removed, and daily cultivation management is conducted.
