Asexual propagation method of michelia compressa

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 ...

AI Technical Summary

Problems solved by technology

Liu Xingjian et al., Taiwan Michelia's introduction performance and grafting and propagation experiments in Nanjing, disclosed the method of grafting Taiwan Michelia as rootstock with white magnolia in 1999 and 2001 respectively, and achieved a survival rate of 27% and 72%. There are disadvantages such as low survival rate and long seedling raising period, generally about 2 years. Tissue culture technology to obtain root-containing seedlings for grafting can greatly increase the number of seedlings, reduce the cultivation cycle, reduce the cost of seedling cultivation, and increase economic benefits
