Embodiment Construction

[0048] A method for asexual propagation of Michelia taiwanensis, which is characterized in that it comprises the following steps: A. cultivation of seedlings of Michelia taiwanensis, B. pretreatment of scion of Michelia taiwanensis, C. grafting method, D, management after grafting;

[0049] Wherein A Taiwan Michelia seedlings are cultivated specifically as follows:

[0050] (1) Selection and disinfection of explants: In late June, select the young tops of the year as explants, rinse them with tap water, and then disinfect them. The disinfection method is: use a brush dipped in a little detergent to scrub the surface, Rinse with running water for 30 minutes, then sterilize with 50-fold diluted 84 disinfectant on a shaking table for 10 minutes, rinse with running water for 3 minutes, disinfect with 75% ethanol for 50-60 seconds on a sterile operating table, and immediately pour 0.1% (0.1 g mercuric chloride: 100ml water) mercuric sterilized for 10 minutes, and finally washed 3 t...

Abstract

The invention relates to an asexual propagation method of michelia compressa. The asexual propagation method includes the steps that firstly, seedlings of the michelia compressa are manufactured; secondly, pretreatment of a scion of michelia compressa is performed; thirdly, a grafting method is adopted; fourthly, management after grafting is performed. Liriodendron chinense is used as a rootstock, and the cut-grafting method is used for grafting the michelia compressa. After cutting is sequentially soaked into a plant growth regulator and 1%DMSO, the rootstock is inserted, and after the cambium of the scion and the cambium of the rootstock are aligned, an anti-drop film is used for tightly winding and wrapping a port from bottom to top. According to the asexual propagation method of the michelia compressa, a great number of root-included seedlings of the michelia compressa can be obtained, the rate of reproduction is 81-86 times, and after the seedlings are obtained, the seedlings are grafted on the Liriodendron chinense, namely the rootstock, and the survival rate is 95%. After transplantation on a field is achieved for two years, the tree vigor is strong, a tree is resistant to diseases and capable of wintering safely, the problem of vacancy of the market resource of the michelia compressa is effectively solved, and the asexual propagation method of the michelia compressa is wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of grafting and propagation of plant seedlings, and in particular relates to a method for asexual reproduction of Taiwan Michelle. Background technique [0002] Michelia compressa from Taiwan belongs to the plant of the genus Michelia L. in the family Magnoliaceae. Large evergreen tree, bark taupe, slightly smooth. The leaves are entire or wavy, leathery, and the leaf buds and flower buds are covered with reddish brown hairs. Among the evergreen broad-leaved tree species, the landscape effect of Taiwan Michelia is outstanding, the tree shape is compact, the trunk is strong, the crown is nearly conical, the side branches are all obliquely extending upwards and approaching the main trunk, and the dark green and shiny leaves are densely grown on 1, The tops of the 2-year-old branches form a green and dense crown in all seasons. The flowers are petite and elegant, and the breeze blows gently, exuding a faint ...
