Description

A kind of basswood propagation by grafiting technology

Technical field

The present invention relates to a kind of basswood propagation by grafiting technology.

Background technology

America forging leaf is roomy, and the long 20cm in elliptical or oval shape, wide 15cm, blade tip is cone type, and limb edge has sawtooth, table Face fold, dark green, smooth disleaf oxter, back side portion has outside brown tuft, Yu Wumao, petiole without hair, long 2.5-3cm.Spend light Yellow, be preced with width 1.5cm width, typically have five petal, fragrance of blooming midsummer, 10 clusters are sagging, every cluster have one long The bract of about 10cm surrounds that bract square is circular or wide lanceolar, and long 3.5-7cm, without hair;The most spherical, close by brown hair, footpath 0.5-1cm, bark brown or lead, above there is long crack, there is fish scale-shaped fold on surface.

Basswood main ecological cause, as very much like with the forging of the indigenous tree purple of Chinese elite in weather, soil etc., have Vast potential for future development.But data shows forging tree flower protandry, the most sterile from flower, cross-pollination, and setting percentage is relatively low, one As less than 10%, and solid there is obvious periodicity, major part fruit is also without the seed of growth.

Summary of the invention

It is an object of the invention to provide a kind of basswood propagation by grafiting technology, to solve proposition in above-mentioned background technology Problem.

For achieving the above object, the present invention provides following technical scheme: a kind of basswood propagation by grafiting technology, including step It is as follows,

1), material selection:

A, choosing of stock, select seedling age 3a, grow vigorous, well developed root system, without freeze injury and the purple forging seedling of pest and disease damage, away from root Border 20cm cutting strunk, diameter of section is 0.5-1.5cm；

B, plants bar and the selection of scion, and planting bar is the healthy and strong nursery stock of America forging taking from 5a seedling age, selects and stock diameter of section The current-year branch that 0.5-1.5cm is close, kind of a bar top is taken from scion, is top more than the 5th leaf bud of top down;

2), scion grafting, scion base portion is whittled into wedge shape, the long 2.5-3cm of bevel, outward slightly thicker than inner side, cut 2-3 bud of reservation afterwards Truncate, then by stock at base portion 20cm truncate, rive downwards from stock section intermediate vertical with cleft grafting cutter, the degree of depth and scion Bevel length is similar, the scion cut is inserted in rootstock opening-cleaving, makes both cambium layer align, touch, then use plastic seal The diameter of bar bondage, stock and scion is the most close；

3), bud grafting, at the top 1cm-1.5cm of scion branch bud, cut, extremely with sharp bud grafting knife-band xylem is the most flat 1cm-1.5cm below bastem, more laterally cut sth. askew and take off bud sheet, retain the petiole of the other blade of bastem, then away from ground on stock 8-10cm, the smooth place of lee face, cut a tangent plane similar with sheet length and width of buddering from the top down, the oblique partial application in lower end is removed and is cut Sheet, bud sheet aligns with cambium layer so that it is being close on the bevel on stock, tighten with plastic sealing strip, bud exposes.

Further, described step 2) and 3) time be spring.

Compared with prior art, the invention has the beneficial effects as follows: this method scion grafting in spring, bud grafting height increament then are respectively It is respectively 9.26mm and 8.88mm for 37cm and 31.9cm, base Diameter growth amount, is widely popularized the need that can alleviate market to nursery stock Ask.

Detailed description of the invention

Below the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment It is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area The every other embodiment that art personnel are obtained under not making creative work premise, broadly falls into the scope of protection of the invention

A kind of basswood propagation by grafiting technology, as follows including step,

1), material selection:

A, choosing of stock, select seedling age 3a, grow vigorous, well developed root system, without freeze injury and the purple forging seedling of pest and disease damage, away from root Border 20cm cutting strunk, diameter of section is 0.5-1.5cm；

B, plants bar and the selection of scion, and planting bar is the healthy and strong nursery stock of America forging taking from 5a seedling age, selects and stock diameter of section The current-year branch that 0.5-1.5cm is close, kind of a bar top is taken from scion, is top more than the 5th leaf bud of top down;

2), scion grafting, scion base portion is whittled into wedge shape, the long 2.5-3cm of bevel, outward slightly thicker than inner side, cut 2-3 bud of reservation afterwards Truncate, then by stock at base portion 20cm truncate, rive downwards from stock section intermediate vertical with cleft grafting cutter, the degree of depth and scion Bevel length is similar, the scion cut is inserted in rootstock opening-cleaving, makes both cambium layer align, touch, then use plastic seal The diameter of bar bondage, stock and scion is the most close；

3), bud grafting, at the top 1cm-1.5cm of scion branch bud, cut, extremely with sharp bud grafting knife-band xylem is the most flat 1cm-1.5cm below bastem, more laterally cut sth. askew and take off bud sheet, retain the petiole of the other blade of bastem, then away from ground on stock 8-10cm, the smooth place of lee face, cut a tangent plane similar with sheet length and width of buddering from the top down, the oblique partial application in lower end is removed and is cut Sheet, bud sheet aligns with cambium layer so that it is being close on the bevel on stock, tighten with plastic sealing strip, bud exposes.

Grafting time is spring.

Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace And modification, the scope of the present invention be defined by the appended.
