Gold leaf elm grafting method

Abstract

The invention discloses a gold leaf elm grafting method. Either the ground grafting or high branch grafting is adopted. White elms are selected as a foundation of a crosstie; scions are selected and prepared, stems with the length ranging from 9 cm to 12 cm of gold leaf elms are selected; grafting is carried out at the end of May in every year after foliation and skin removing of trees; the stored scions and taken out to dewaxed, and one ends of the stored scions are sharpened to be inserted into the crosstie, tightly wrapped by environment-friendly plastic strips and then sleeved with environment-friendly plastic bags; after 10 days, the environment-friendly plastic bags and the environment-friendly plastic strips are removed. The gold leaf elm grafting method is applicable to grafting with white elm seedlings growing for one to two years as crossties. By the adoption of the gold leaf elm grafting method, the gold leaf elm survival rate is more than 95% and is high, the reproduction speed is high, and the problem that large-area planting of gold leaf elm cannot be achieved due to the fact that a small number of gold leaf elms exist is solved. Environment-friendly plastic bags are used in the grafting method, so that pressure caused by non-degradable plastic bags to environment is reduced or even avoided.

Description

technical field [0001] The invention relates to the grafting technology of agricultural plants, and in particular provides a method for grafting elm elm. Background technique [0002] As a landscape tree, golden leaf elm grows rapidly, has dense branches, is resistant to heavy pruning, has rich shapes, and has high ornamental value. It gradually replaces other landscape trees. In addition, golden leaf elm has strong adaptability to cold and arid climates, and has strong resistance to salt and alkali. The engineering maintenance management is relatively extensive, so it is an irreplaceable species of landscape trees. Golden leaf elm is a variant of white elm. It has a long natural reproduction cycle and is rare in number. Although it has a tendency to replace other landscape tree species, it still cannot be planted in large areas. Contents of the invention [0003] The object of the present invention is to provide a method for grafting of elm elm, which adopts one of groun...
