Micheliacompressa grafting method

Abstract

The invention relates to a micheliacompressa grafting method, comprising the steps of A, tulip tree stock cultivation, B, micheliacompressa cion preprocessing, C, the grafting method and D, post-graft management, wherein the micheliacompressa is grafted by adopting the tulip tree as the stock, cutting slips are inserted into the stock after being soaked by a plant growth regulator and 1% of DMSO (dimethylsulfoxide) in sequence, and the after forming layers of the cutting slips and the stock are leveled, an anti-drop film is adopted to tightly wind and wrap the joint from top to bottom. The micheliacompressa grafting method can enable the seedling of the tulip tree grafted in the next year to achieve 98%, the survival rate of the grafted micheliacompressa to achieve 95% and has a broad 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 grafting method 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 fragrance. Thro...

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 defects such as low survival rate and long seedling cultivation cycle, generally about 2 years, general tree vigor after transplanting, easy to be frozen, and difficult to survive low temperature in winter, which makes the commercial cultivation cycle longer and increases the cost of seedling cultivation; The best time for commercial seedlings to go on the market affects economic benefits
