Embodiment 1

[0028] A kind of cultivation method of ring elm, comprises the following steps:

[0029] (1), grafting of Ulmus ulmis, grafting by branch grafting method: in spring, select the branches of annual Ulmus ulmis growing robustly and without pests and diseases as scions, and the scions of Ulmus ulmis are cut before germination, stored in sand under natural conditions in the field, before grafting, from Take it out from the sand storage, soak in water for 24 hours, then cut the branches into branches with one bud left, seal the cut wound with paraffin, and use it as a scion for later use. The branches are cut off or sawn off as rootstock, and the lower end of the scion is cut into a horse-ear-shaped large slope, and then on the windward side of the rootstock, the cortex of the rootstock is pried off with a knife or hand, and the large slope of the cut scion faces the rootstock. The xylem is inserted at one time until the large slope of the scion is no longer white, and then the graf...

[0034] A kind of cultivation method of ring elm, comprises the following steps:

[0035] (1), grafting of Ulmus ulmis, grafting by branch grafting method: in spring, select the branches of annual Ulmus ulmis growing robustly and without pests and diseases as scions, and the scions of Ulmus ulmis are cut before germination, stored in sand under natural conditions in the field, before grafting, from Take it out from the sand storage, soak in water for 24 hours, then cut the branches into branches with one bud left, seal the cut wound with paraffin, and use it as a scion for later use. Cut off or saw off as a rootstock, cut the lower end of the scion into a horse-ear-shaped slope, and then pry off the cortex of the rootstock on the windward side of the rootstock with a knife or hand, and place the large slope of the scion facing the xylem of the rootstock , insert it at one time until the large slope of the scion is no longer white, and then bind the grafted part with a plastic b...

Embodiment 3

[0040] A kind of cultivation method of ring elm, comprises the following steps:

[0041](1) Grafting of weeping elm, grafting by bud grafting: in the growing season, select the branches of the annual weeping elm that grow robustly and have no diseases and insect pests as the scion, then cut the branches into branches with 2 buds, choose common elm trees that have just germinated Cut off or saw off the branches of the elm as the rootstock, cut the lower end of the scion into a horse-ear-shaped slope, and then pry off the cortex of the rootstock with a knife or hand on the windward side of the rootstock, and place the large slope of the cut scion facing the rootstock The xylem of the scion is inserted at one time until the large slope of the scion is no longer white, and then the grafted part is bound with a plastic bag;

[0042] (2) After the grafted weeping elm grows branches, take a branch to form an "8" shape, thus forming two rings, and the remaining branches are removed im...

Abstract

The invention belongs to the technical field of cultivation methods of landscape modeling tree species and particularly relates to a cultivation method and an application of an annular elm. The cultivation method of the annular elm comprises following steps: (1), a common elm which is 3 m high is selected as a stock, and is grafted with ulmus pumilavar pendula scions by selecting an appropriate height according to application of the elm; (2), after ulmus pumilavar pendula grows branches, the needed branches are retained to constitute a ulmus pumilavar pendula ring, and the other branches are cut off at the germination stage; (3), the ulmus pumilavar pendula branches are grafted with common elm scions, the bilaterally symmetrical common elm scions keep balanced upward growth, and the tree is formed finally. The problem of single elm modeling in the city at present is solved, the elm not only can realize the greening effect for the city, but also can enhance the decorative sense of the city, meanwhile, the ulmus pumilavar pendula ring is used as a ring seat, and therefore, the value of the elm is further developed.

Description

technical field [0001] The invention belongs to the technical field of garden modeling tree species cultivation methods, and in particular relates to a method for cultivating ring-shaped elm and its application. Background technique [0002] Elm is a positive tree species that likes light, is resistant to drought, cold, and barrenness, does not choose soil, and has strong adaptability. It can thrive even under different climatic conditions in the vast land of our country. Well-developed root system, strong wind resistance and soil retention. It is anti-pollution and has strong ability to retain dust on the leaf surface. Not only can it increase the oxygen concentration through photosynthesis, but it is also a good medicine for the serious air quality problems in urban construction. In addition, elm has the characteristics of strong germination, resistance to pruning, fast growth and long life. [0003] But the elm plant in the city does not have any molding at present, ca...
