Description
Technical field
The present invention relates to breeding plant technical fields, more particularly to a kind of breeding method of colorful leaf elm.
Background technique
Elm: also known as Japanese elm is known as the title of " elm pimple ", is Ulmaceae deciduous tree, and treelet bark is smooth, taupe or
Light gray, the skin dark gray of big tree, irregular depth lobe are coarse；Sprig is hairless or hairiness, without the phellem layer and protrusion expanded
Cork wing；Hibernaculum is subsphaeroidal or oval.Elliptic leaf shape is oval etc., and blade face is smoothly hairless, and there is pubescence in when blade back children, becomes nothing afterwards
Hair or part arteries and veins have tufted hair, and there is pubescence in petiole face.Hua Xianye opening is giving birth to the axil of branch into fasciation shape.Samara is dilute
Ovate is round.The flowering fruit bearing stage 3-6 month
Color leaf tree is also known as color leaf arbor, refers to that its blade, stem etc. show the plant of heterochromatic (non-green) throughout the year, such as gold
Leaf metasequoia, bedleaf cherry plum, Acer palmatum ' Atropurpureum', gold leaf Chinese scholar tree, the red smoke tree of purple leaf, Lan Bingbai, Wong Kam-po tree, floral leaf Lan Ren etc..
Color leaf tree is popular tree species in recent years.It can become a scape of gardens Tourism Garden of Ecological, or urban afforestation increases
Add color.Wherein modern garden Tourism Garden of Ecological meets the person's of visiting a park vision to allow tourist in the unique charm for wherein experiencing the Nature
The needs of effect exactly configure foliage plant in addition to pooled applications flowers different with configuration.Foliage tree kind is because with seasonal variations
Obviously, it is different to watch length of time.Ornamental form:
Spring sees leaf: red, aubergine and yellow is presented in the tender leaf of spring kainogenesis, colourful more under the brushing of spring breeze
Coloured silk, great glamour, and because its spring scenery is red or yellow, it is warm tones, warmness can be increased to early spring barely warm but still cool, feel people
To comfortable and pleasant.
Autumn sees leaf: at this point, Acer palmatum ' Atropurpureum' has started to change colour, the especially Acer palmatum ' Atropurpureum' of full wafer mass-planting has imposing manner, " sees red all over the hills and plains very much
All over, row upon row of trees exhaustion ", this is shocking scene.
Whole year sees leaf: normal Colour-leaved trees and spot Colour-leaved trees keep gay colours or have coloured silk in the entire season of growth
Spot, especially midsummer and severe winter etc. lack the adolescence, can enrich the color of city trees and shrubs.This plant was both economical and economical,
Throughout the year or sees flower or see leaf.Such as: red autumnal leaves oriental cherry.
Color plant is generally divided into foundation planting, isolated planting tree, grove, woodlot using plantation form in gardens.
Most of color leafed plants are combined in addition to itself different color of every kind of trees, are exactly that different color trees are cultivated in ornamental
Garden.Color is extremely dull, and the probability of success is low in cultivating process, and the success rate of elm is especially low, influences the economic effect cultivated
Benefit.The present invention has studied the inoculation method of colorful leaf elm as a result, to improve ornamental values and the economic values.
Summary of the invention
The present invention solves the technical problem of existing more color leafed plants, dull coloring and success rate is low influences more
The development of color leafed plants.
In order to solve the above technical problems, a technical solution of this use is: providing a kind of cultivation side of colorful leaf elm
Method, the breeding method the following steps are included:
1. the selection of stock, select 2 years or more and 3.0~4.0cm be thick, no disease and pests harm, stalwartness, well developed root system nursery stock
Make stock；
2. the full Health of Tree branch of 0~1 year life, leaf bud is picked up from the selection of scion；
3. stock need to be grafted at scion matching smearing reagent by grafting, select 2~3 different leaf colors, leaf trees scion into
Row grafting, is completed.
In a specific embodiment of the invention, the grafting method is selected from bud and connects, scion grafting, one of is abutted against or a variety of
Mixing.
The bud connects, and selects two or more different leaf color, leaf rosaceae trees.Cut on stock it is a piece of,
The inclined cut of a low-angle is done, a small groove is generated.The bud of scion is placed into the center of notch, scion is in stock
On as far as possible alignment place.It is fastened scion with flexible rubber material around stock.External scion bud is connected to anvil
The wooden top obtains space advantage, and anthology stock top leaf bud grafts in the affinity advantage that this trees is applied in stock lower part.It is transferring
It connects after leaf bud survives, prunes the stock branch of topmost grafting bud or more, it is ensured that scion bud has sufficient moisture and nutriment supply.
One tree grows leaf not of the same race after grafting survival.
The scion grafting, the trees for selecting two or more different leaf color, leaf affiliation close.In warm and moist
Season, removal connect end of the ear, and the scion of acquisition tilts excision end again.It selects the stock branch that can be matched with scion to do to incline
Beveling is cut, then a tongue type wedge mouth is cut on the section of stock and scion, it is necessary to allow the two matching to get up to be intimately associated together, really
The subcortical forming layer of the two is protected all to be aligned.It is wound up with flexible rubber material around stock and scion engaging portion,
Expose leaf bud above scion.All twigs being grown under grafted branch are all removed, but to leave partial leaflet, until grafted branch
Until the nutrient on tree can be successfully drawn to.
The trees that are described to be abutted against, selecting two or more different leaf color, leaf affiliation to be closer to.The anvil being abutted against
The wooden root system wants flourishing, sapling of the plantation for (especially cut off and be not easy after maternal plant to take over a job) plant scion around it.When being abutted against
There to be the plant of root system, is being easy to stem's all truncated section cortexes close to each other, is being interconnected immediately, with flexible rubber
Material is wound up around stock and scion engaging portion.After interface healing, the top of stock and the lower part of scion are cut off,
As independent new plant.
In one particular embodiment of the present invention, the grafting method connects for bud.
In the present invention, the reagent is selected from one of fragrant amino thiocarbamide, p-totuidine base thiocarbamide, diethyl aminoethyl hexanoate or a variety of
Mixture aqueous solution.
In the present invention, the reagent is the mixture aqueous solution of p-totuidine base thiocarbamide, diethyl aminoethyl hexanoate.
In a specific embodiment of the invention, the toluidino thiourea solution concentration is 1~3.4wt%, and amine is fresh
Aqueous solution of ester concentration is 6~9.5wt%.
In one particular embodiment of the present invention, the toluidino thiourea solution concentration is 2.8wt%, diethyl aminoethyl hexanoate
Concentration of aqueous solution is 8.3wt%.
In the present invention, the scion is selected from two or more of mixing of Chinese pumila, gold leaf Chinese scholar tree, yellow Yuzhong.
In one particular embodiment of the present invention, the scion is Chinese pumila, Huang Yu.
In the present invention, the scion rugosity is 0.5~1.0cm.
The beneficial effects of the present invention are: being in contrast to the prior art, fast, sight is operated using breeding method of the invention
It is good to appreciate effect, success rate is high, and success rate is up to 99.8% in one particular embodiment of the present invention.
