Abstract
The invention belongs to garden shaping tree species breeding method technical fields, breeding method and its application more particularly to a kind of annular elm, a kind of breeding method of annular elm highly grafts Ulmus pumila var. pendula scion according to the selection of the purposes of elm is suitable the following steps are included: (1), the common elm for select 3 meters high be stock；(2), after Ulmus pumila var. pendula branch out, the branch of needs is left and constitutes Ulmus pumila var. pendula ring, remaining branch is just cut in the budding period, and (3) graft common elm scion on Ulmus pumila var. pendula branch, it keeps symmetrical common elm scion balance to grow up, ultimately forms tree.The present invention solves the problems, such as that elm moulding is single in current city, makes elm that can not only generate Greening functions to city, moreover it is possible to enhance the decoration sense in city, while the present invention is used Ulmus pumila var. pendula ring as annular seat, further developed the value of elm.
Description
Technical field
The invention belongs to garden shaping tree species breeding method technical fields, and in particular to it is a kind of annular elm breeding method and
It is applied.
Background technique
Elm is heliophilous species, light, drought-enduring, is resisted cold, barren-resistant, does not select soil, adaptability is very strong, even China is distant
It can also grow up strong and sturdy under different weather conditions on wealthy territory.Well developed root system, wind resistance power, soil conservation power are strong.Have resistance tocrocking,
Blade face regulation of absorbing dust capability is strong.Not only oxygen concentration can be promoted by photosynthesis, but also to air matter serious in urban construction
Amount problem is also one good medicine.Furthermore there are also the resistance to trimmings by force of rudiment power for elm, and growth is fast, the feature of service life length.
But the elm kind plant in city cannot decorate city without any moulding well at present, and purposes is single.
Summary of the invention
The present invention, aiming to the above problems, provides a kind of breeding method of annular elm and its applications.
The invention adopts the following technical scheme in order to achieve the above objectives:
A kind of breeding method of annular elm, comprising the following steps:
(1), Ulmus pumila var. pendula is grafted, graft using whip grafting: spring selects the branch of annual Ulmus pumila var. pendula robust growth no disease and pests harm
For scion, Ulmus pumila var. pendula scion is cut before germination, and sand is hidden under the natural conditions of field, before grafting, is taken out from sand hiding, is soaked in water
Branch, is then cut into the branch section for staying 2 buds of l-, the wound cut off is sealed with paraffin by bubble 24 hours, spare as scion, is transferred
When connecing, common elm is selected, the common elm branch just to have germinateed is cut off or amputated as stock, one knife of scion lower end is whittled into
The big inclined-plane of horse ear shape, the side windward on stock, is pried open stock cortex with knife or hand, by the big inclined-plane of the scion cut immediately
Xylem towards stock is disposably inserted into until the big inclined-plane of scion do not show money or valuables one carries unintentionally, then bundlees grafting part with polybag；
(2), after Ulmus pumila var. pendula branch out to be grafted, branch is left and taken, constitutes annulus, forms Ulmus pumila var. pendula ring；
(3), common elm branch is grafted, is grafted using bud grafting method: after Ulmus pumila var. pendula ring is constituted, on the end of the branch of Ulmus pumila var. pendula branch,
Common elm branch is grafted, the season of growth, selecting the branch of annual common elm robust growth no disease and pests harm is scion, grafting
When, it is desirable that scion and Ulmus pumila var. pendula stock thickness are close, 1-2 ㎝ under scion bud, and 1-2 ㎝ on bud a, knife is whittled into transferring for date core shaped
Junction, few with wooden, immediately on the top of stock Ulmus pumila var. pendula, a knife is whittled into the scion that will have been cut with an equal amount of wound of scion
It is placed on stock wound, and is sticked together by the viscosity of elm sap, then bundled tightly with polybag, common elm
Branch grows up to form tree.
Further, the Ulmus pumila var. pendula ring in the step (2) is divided into monocycle, bicyclic and polycyclic, monocycle: the Ulmus pumila var. pendula of grafting grows branch
After item, a branch being left and taken, constituting annulus, remaining branch just removes immediately in the budding period, and the annulus of composition is with an equal amount of
Annulus iron wire is fixed；Bicyclic elm: after the Ulmus pumila var. pendula branch out of grafting, the branch difference structure of left and right two in the same plane is left and taken
At annulus or branch composition " 8 " type is left and taken, to constitute two annulus, remaining branch just removes immediately in the budding period, will
Two annulus constituted are tied up to be fixed on annulus iron wire；Polycyclic elm: after the Ulmus pumila var. pendula branch out of grafting, no less than three are left and taken
A branch, respectively constitutes annulus, remaining branch just removes immediately in the budding period, and multiple annulus of composition are tied up respectively in annulus
It is fixed on iron wire.
Further, the common elm branch grafted in the step (3), the symmetrical common elm branch in left and right to
It to keep balancing during upper growth, pinching need to stay sublateral shoot on enriching shoot if uneven or sublateral shoot is gone to pay attention to, on weak branch
Retain and then all retain, after ready to balance, then remove extra branch, to reduce the light of elm by reducing branch area and blade
Cooperation is used, to slow down the speed of growth of elm branch, two branch balanced growths is kept for a long time, to keep Ulmus pumila var. pendula ring
Shape invariance shape.
Further, Ulmus pumila var. pendula ring can select 1-2 to grow up to according to the diameter of required ring.
Further, several Ulmus pumila var. pendula scion can be grafted simultaneously when grafting Ulmus pumila var. pendula scion in the step (1).
Further, bud grafting method grafting can also be used when step (1) the grafting Ulmus pumila var. pendula, grafting is general in the step (3)
Whip grafting grafting can also be used when the branch of Tongyu.
A kind of application of annular elm, for annular seat or ornamental tree.
Further, the common elm stock height of grafting Ulmus pumila var. pendula is 0.5-0.6 meters when annular elm is used for annular seat, Ulmus pumila var. pendula
The grafting height of scion is apart from ground 0.4-0.5 meters, and the Ulmus pumila var. pendula ring of formation is in horizontally disposed；Annular elm is used for for watching
When, the common elm stock height for grafting Ulmus pumila var. pendula is 2.5-3 meters, and the grafting height of Ulmus pumila var. pendula scion is to be formed apart from ground 2-3 meters
Ulmus pumila var. pendula ring in being vertically arranged.
Invention has the advantage that compared with prior art
1, annular elm of the invention, can not only play the role of green planted city, and make city with more ornamental value；
2, it is always maintained at balance in the symmetrical common elm branch growth course that the present invention grafts, can be very good
Keep the shape invariance shape of Ulmus pumila var. pendula ring；
3, Ulmus pumila var. pendula ring is used the value for further developing elm by the present invention as annular seat；
4, the size and quantity of the adjustable Ulmus pumila var. pendula ring of the present invention number, change the moulding of annular elm, make annular elm
Moulding have diversified feature.
