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

The preparation method of the vertical elm of tree-shaped gold goal

Technical field

The present invention relates to a kind of ornamental trees and shrubs graft modeling method, be specifically related to a kind of method of tree-shaped elm two look dimorphism moulding, belong to ornamental trees and shrubs modeling technology area.

Background technology

In modern garden, much with the trees of flower that open several colors (kind) on one tree, but and for moulding object, the ornamental trees and shrubs of grafting different shape were never met on same one tree.

General elm kind weeping branch elm or gold leaf elm, all moulding is applied in gardens respectively.Single landscape, lacks peculiar sense.Also never met the report of the peculiar sight sculpt of growing on same elm weeping branch elm and two kinds of colors of gold leaf elm, two kinds of forms.

Summary of the invention

The object of the invention is to overcome above-mentioned deficiency, a kind of brand-new ornamental trees and shrubs Modeling Types is provided, make the long peculiar view that has two shapes of two kinds of colors on one tree shape elm.Formation take gold leaf elm ball as main scape, take vertical elm as background, weeping branch elm is hung down, and to set off gold leaf elm by contrast spherical for a flat branch sheet, under contrast, gold goal is more outstanding and emphasize.In the literature, be referred to as " gold goal hang down elm " moulding tree.To improve sight, artistry and the scientific and technological content of ornamental trees and shrubs.

The object of the present invention is achieved like this: the ornamental trees and shrubs newtype of having two kinds of shapes of two kinds of colors on a kind of tree-shaped elm---" gold goal hang down elm " peculiar landscape tree, and its preparation method is:

Step 1, stock are cultivated

Cultivate thin and tall elm seedling by sowing dense planting method (seeding row spacing 6*6cm) April, naked transplanting of Second Year, and seeding row spacing 130*130cm, fixed dry at trunk height 130cm place, strengthen rich water and maintenance management, promote growth.

Step 2, high-grafting

In the 7-8 month, with polygerm long tube, overlap connection, select stock and scion that thickness is identical, to being about the weeping branch elm scion of 5cm, stubborn flute is socketed on elm (stock) branch of having shelled the long bark of 5cm, scion sleeve pipe is set to the elm branch bottom of peeling 5cm always, the two is coincide, without tying up and bagging.Gold leaf elm scion grafting is identical therewith.Complete high-grafting process.

Step 3, pruning

After high-grafting survives, the branch sheet that weeping branch elm self-assembling formation hangs down flat, and the constantly upwards growth of gold leaf elm, as long as it is carried out to repeatedly cutting back, has just formed gold leaf elm hemispherical tree crown.So far, the peculiarly shaped view of tree-shaped two look dimorphism elm---" gold goal hang down elm " just made out.

Specific implementation method:

One, stock is cultivated

Take to sow dense planting method (seeding row spacing 6*6cm) with elm money and cultivate thin and tall elm seedling April, naked transplanting of Second Year, and seeding row spacing 130*130cm, fixed dry at trunk height 130cm place, strengthen rich water and maintenance management, promote growth.

Two, high-grafting

In the 7-8 month, with polygerm long tube, overlap connection, select stock and scion that thickness is identical, to being about the weeping branch elm scion of 5cm, stubborn flute is socketed on elm (stock) branch of having shelled the long bark of 5cm, scion sleeve pipe is set to the elm branch bottom of peeling 5cm always, the two is coincide, without tying up and bagging.Gold leaf elm scion grafting is identical therewith.Complete high-grafting process

Three, pruning

After high-grafting survives, weeping branch elm grows up to the branch sheet that hangs down flat naturally, and the constantly upwards growth of gold leaf elm, as long as it is implemented to repeatedly cutting back, has just fashioned into gold leaf elm hemispherical tree crown.So far, the peculiarly shaped view of tree-shaped two look dimorphism elm---" gold goal hang down elm " just made out.

Embodiment

Between 2013 Nian Chun， Beijing Forestry University dormitory building of worker, in greenery patches, biennial three strain elms are first carried out to dry (130cm) surely, implemented again grafting high and changing head, be expected can make first appearance the end of the year.

Claims

1. on a tree-shaped elm, have the ornamental trees and shrubs newtype of two kinds of shapes of two kinds of colors the gold goal peculiar landscape tree of elm that hangs down, is characterized in that its preparation method is:

A) by the method for dense planting, cultivate stock nursery stock.

B) with the scion of weeping branch elm and the scion of gold leaf elm respectively high being connected on elm stock, carry out high-grafting.

C) after pruning high-grafting survives, the branch sheet that weeping branch elm self-assembling formation hangs down flat, and the constantly upwards growth of gold leaf elm, as long as it is carried out to repeatedly cutting back, has just formed gold leaf elm hemispherical tree crown.So create the peculiarly shaped view of tree-shaped two look dimorphism elm---" gold goal hang down elm ".

2. a kind of ornamental trees and shrubs newtype according to claim 1

" gold goal hang down elm " peculiar landscape tree, is characterized in that by sowing dense planting method (seeding row spacing 6*6cm), cultivating thin and tall elm seedling, naked transplanting of Second Year April, seeding row spacing 130*130cm, fixed dry at trunk height 130cm place, strengthen rich water and maintenance management, promote growth.

3. a kind of ornamental trees and shrubs newtype according to claim 1 and 2

" gold goal hang down elm " peculiar landscape tree, the concrete operation method that it is characterized in that high-grafting is: in the 7-8 month, with polygerm long tube, overlap connection, select stock and scion that thickness is identical, to being about the weeping branch elm scion of 5cm, stubborn flute is socketed on elm (stock) branch of having shelled the long bark of 5cm, scion sleeve pipe is set to the elm branch bottom of peeling 5cm always, the two is coincide, without tying up and bagging.Gold leaf elm scion grafting is identical therewith.
