Method for cultivating tree-shaped gold-ball elms

Abstract

The invention relates to a method for cultivating tree-shaped gold-ball elms. The method aims to create a 'gold-ball ulmus pumila' which is an exotic landscape elm and is a novel type of garden tree, and two colors and two shapes grow on the elm. The method is characterized in that thin and tall elm seedlings are cultivated by a seeding close planting process in April, bare roots are transplanted in the second year, trunks are set when the heights of the tree trunks reach 130cm, and fertilizer and water management and conservation management are intensified, so that growth of the elm seedlings can be promoted; rootstocks and scions with identical thicknesses are selected by a multi-bud long tube sleeving process in July and August, the ulmus pumila scions with the lengths of about 5cm are wrung and sleeved on elm branches (the rootstocks) of which barks with the lengths of 5cm are peeled, scion sleeving tubes are sleeved to the bottoms of the elm branches of which the barks with the lengths of 5cm are peeled, and each scion sleeving tube and the corresponding elm branch are matched with each other without binding or bagging; scion grafting for ulmus pumila cv. Jinye is carried out in the same manner; a top grafting and breed changing procedure is completed; drooping and flat branches of ulmus pumila naturally grow after the ulmus pumila survives, the ulmus pumila cv. Jinye continuously grows upwardly, and a hemispherical crown of the ulmus pumila cv. Jinye can be formed only by means of repeatedly cutting back the ulmus pumila cv. Jinye.

Description

technical field [0001] The invention relates to a grafting modeling method for ornamental trees, in particular to a two-color and two-shape modeling method for tree-like elms, and belongs to the technical field of ornamental tree modeling. Background technique [0002] In modern gardens, it is not uncommon to have trees with flowers of several colors (species) on the same tree, but it has never been seen to graft different types of ornamental trees on the same tree for modeling purposes. [0003] The general elm species, weeping elm or golden leaf elm, are shaped separately and used in gardens. The landscape is monotonous and lacks a sense of strangeness. I have never seen reports of the strange landscape shapes of weeping elm and golden leaf elm growing on the same elm tree in two colors and two forms. Contents of the invention [0004] The purpose of the present invention is to overcome above-mentioned deficiency, provides a kind of brand-new landscaping tree modeling ...
