The method of grafting white magnolia to purple magnolia

Abstract

The invention discloses a method for grafting magnolia liliiflora to michelia alba. The method is characterized by comprising the following steps: (1) selecting a michelia alba branch of which the age is more than 2 years and the main diameter is more than 1cm to serve as a stock, wherein the difference between the diameter of the top and the diameter of the bottom of the michelia alba branch is small, and the michelia alba branch is free of pests; (2) selecting an annual magnolia liliiflora branch to serve as a cion, wherein the length of magnolia liliiflora is from 10cm to 15cm; earthing the magnolia liliiflora branch, and then, performing patch grafting on the magnolia liliiflora branch and the michelia alba branch with a diagonal plane of 45 degrees; (3) performing conservation according to traditional tree grafting management; earthing on the magnolia liliiflora refers to paving the magnolia liliiflora flat on a nutrition matrix, covering the paved magnolia liliiflora branch with a layer of mixed soil which is 5-10cm thick, keeping the soil water content of the nutrition matrix and the soil water content of the mixed soil be 10-20 percent, earthing for 10-25 days, and then, taking out for grafting. The method disclosed by the invention is simple and feasible; compared with the traditional breeding method, the method disclosed by the invention has the advantages that the survival rate can reach more than 90 percent, the survival rate after grafting is greatly increased, the planting cost is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of grafting, in particular to a method for grafting white magnolias with purple magnolias.
