Grafting and shaping method of big ulmus parvifolia tree

Abstract

The invention discloses a grafting and shaping method of a big ulmus parvifolia tree. The method includes the steps of selecting a big ulmus parvifolia tree 20 years old or older with the diameter of 30 cm or more and the height of 7 m or more, cutting branches, transplanting and planting the big ulmus parvifolia tree, grafting grafted branches of golden leaf ulmus pumilavar pendula onto the big ulmus parvifolia tree, and conducting synusia shaping on the braches of golden leaf ulmus pumilavar pendula when the branches of golden leaf ulmus pumilavar pendula are 1.5 m long or longer after grafting. By means of the method, the additional value of the big ulmus parvifolia tree is improved, the characteristics of a primary species are broken through, the advantages of two products are combined, the synusia shaping mode is utilized, gold yellow leaves of ulmus pumilavar pendula are completely displayed with the aid of high branches of the big ulmus parvifolia tree, and the scene of getting a new lease of life is achieved. Meanwhile, the forming time of shaped trees is shortened, and cost is reduced; grafting and shaping are directly achieved through the big ulmus parvifolia tree, grafting is conducted in the current year, shaping is conducted in the next year, forming and selling are conducted in the third year; compared with the traditional situation that it takes people several decades to shape a big tree, forming time is shortened and land and labor cost are reduced.

Description

technical field [0001] The invention relates to a method for grafting and modeling forest trees, in particular to a method for grafting and modeling a large elm tree. Background technique [0002] During the transplanting process of the big elm tree (take the company’s acquisition as an example), for the convenience of transportation, only the main branch will be kept, and all the side branches will be sawed off (the short part of the side branch can be kept as needed), and then several large trees will be loaded and transported to reduce transportation costs. How to make the transplanted elm tree have more image characteristics, and how to make up for the weakness of the abrupt and single tree shape caused by pruning, has become a management and maintenance problem in the later stage, which directly affects the economic value of the tree? [0003] The existing models of the elm tree have limited eye-catching power due to the small leaves and dull leaf color, and the modeli...
