A kind of velvet crape myrtle high grafting seedling raising method

Abstract

The invention belongs to the technical field of tree vegetative propagation methods, and specifically relates to a method for raising seedlings by high grafting of velvet crape myrtle. The method comprises the following steps: selecting and cultivating rootstock seedlings: selecting 25-year-old seedling crape myrtle trees as rootstocks; velvet crape myrtle The scion is grafted to the crape myrtle tree, and the cultivation base is selected; the selection and collection of the scion: the developing branches of the velvet crape myrtle sapling are selected as cuttings, and 2-3 buds are reserved for each cutting; the upper joint is flat, 1.3cm away from the terminal bud, and the lower joint is It is flat, below the internodes or below the buds to facilitate healing; the present invention is mainly used to provide a method for raising seedlings by high grafting of velvet crape myrtle. Compared with the prior art, the method for raising seedlings by high grafting of velvet crape myrtle of the present invention not only has simple conditions, The operation is easy, the reproduction cost is low, and it can also significantly increase the success rate of grafting, reduce the incidence of powdery mildew, and obviously improve the quality of grafted seedlings.

Problems solved by technology

The present invention is mainly used to provide a method for raising seedlings by high grafting of velvet crape myrtle, which is used to solve the problem that the sealing wax is made of paraffin, which is brittle and easily broken or even crushed after being stressed, and the melting point of paraffin is low, which in turn leads to When sealing the wax, the grafting joints are sealed too tightly. Under the strong sunlight, the sealing wax is easy to melt and penetrate into the buds of the scion, which will kill the sprouting buds of the scion and affect the survival rate of the graft.
