Abstract
The invention discloses a kind of methods for improving Acacia continma graft survival rate, using cut-grafting method, by stock above the well-grown first branch living cutting strunk at 3~5cm, and retain the work branch；After cutting strunk, the notch of longitudinal sectional 2~4cm from the top down from the forming layer of side makes its expose xylem, forming layer and bast；It will be whittled into section with the processed scion of IBA, and cut 2 bevels；Then it keeps to the side to cut on stock along cotyledon petiole direction, the scion cut is inserted into immediately, clutches junction, anvil fringe forming layer is opposite, and stock and the forming layer of scion is made to coincide naturally, and it is real to wrap drawing with plastic foil.Propagation by grafiting technology of the invention can not only make Acacia continma retain the merit of stock and scion, can also enhance its adaptability and resistance to environment, shorten the breeding time limit, substantially increase graft survival rate, and high survival rate is up to 81%；Meanwhile propagation by grafiting technology of the invention is also to promote the most effective approach of high quality tree species generation.
Description
Technical field
The present invention relates to forest genetics reproduction technique fields, more particularly, to a kind of raising Acacia continma graft survival rate
Method.
Background technique
Roll up English yearning between lovers（Acacia.cincinnata）, the tree-like tall and big, resistance of tree species, have nodule nitrogen fixation effect.In 90
China is introduced at the beginning of age, is the quick growing species of trees of short circulation phase, trunk is logical straight, and seedling differentiation degree is low, forest form is neat, general
Under land occupation condition afforest 6-8a can final felling, be eucalyptus mostly generation even plant ground be ideal crop rotation and substitution tree species.Timber is averaged
Conduit width minimum is about 199.41 μm, and Measuring Average Microfiber Thread Angle is up to 18.8 °, density 617kg/m3, form is good, wood
Line is beautiful, for making solid wood furniture and decoration veneer and quality pulp tree.
For a long time, Acacia Species seed in China's is mainly introduced from Australia's purchase, expensive, is greatly hindered
The process of artificial culture breeding.However China is concentrated mainly on cutting propagation and tissue cultures side to its vegetative propagation at present
Face, but because of many reasons, breeding coefficient is lower, these practical problems all constrain Acacia continma and promote and apply use.Propagation by grafiting
It so that achievements in forest-tree seedling is retained stock and scion merit, it can also be enhanced to environmental suitability and resistance, contracting
The short breeding time limit, and substantially reduce production cost.
Summary of the invention
It is an object of the invention in view of the shortcomings of the prior art, providing a kind of side for improving Acacia continma graft survival rate
Method.
To achieve the above object, the present invention adopts the following technical scheme that：
A method of Acacia continma graft survival rate, which is improved, using cut-grafting method specifically includes following steps：
（1）The selection of stock：It selects ground diameter in 9~12mm and the Acacia continma at least retaining well-grown side branch living grows directly from seeds
Seedling is as stock；
（2）The acquisition and processing of scion：Scion selects semi-lignified spray in the middle part of Acacia continma elite stand, with adopting with connecing, if you need to outer
Ground acquires scion, fresh-keeping at 10-15 DEG C；50mgL is used in the scion of acquisition before grafting-1Exogenous hormone IBA impregnate
1min；
（3）Grafting period：The 3-4 month；
（4）Engrafting method：By stock above the well-grown first branch living cutting strunk at 3~5cm, and retain the work branch；Cutting strunk
Afterwards, the notch of longitudinal sectional 2~4cm from the top down from the forming layer of side makes its expose xylem, forming layer and bast；It will
Step（2）Processed scion is whittled into section, and length 4cm stays 2~3 kryptoblast, cuts 2 bevels, two bevels difference that one is long and the other is short
For 2.0cm and 0.5cm；Then it keeps to the side to cut on stock along cotyledon petiole direction, the scion cut is inserted into immediately, clutches combination
Place, anvil fringe forming layer is opposite, and stock and the forming layer of scion is made to coincide naturally, and it is real to wrap drawing with plastic foil；
（5）Managing after grafting：After grafting survival, the work side shoot on former stock and rudiment of erasing in time are wiped out immediately, is poured on time
Water.
The beneficial effects of the present invention are：Propagation by grafiting technology of the invention can not only make Acacia continma retain stock with
The merit of scion can also enhance its adaptability and resistance to environment, shorten the breeding time limit, substantially increase grafting
Survival rate, high survival rate is up to 81%；Meanwhile propagation by grafiting technology of the invention is also to promote the most effective way of high quality tree species generation
Diameter.
Detailed description of the invention
Fig. 1 is cut-grafting method schematic diagram of the invention；
Fig. 2 is the management schematic diagram after grafting survival.
Specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described, but the present invention is not limited only to these embodiments.
Embodiment
A method of Acacia continma graft survival rate being improved, using cut-grafting method（Such as Fig. 1）, specifically include following steps：
（1）The selection of stock：It selects ground diameter in 10mm and at least retains the Acacia continma seedling of well-grown side branch living
As stock；
（2）The acquisition and processing of scion：Scion selects semi-lignified spray in the middle part of Acacia continma elite stand, with adopting with connecing；Acquisition
50mgL is used in scion before grafting-1Exogenous hormone IBA impregnate 1min；
（3）Grafting period：Mid-March in spring；
（4）Engrafting method：By stock above the well-grown first branch living cutting strunk at 4cm, and retain the work branch；After cutting strunk,
The notch of longitudinal sectional 3cm from the top down from the forming layer of side makes its expose xylem, forming layer and bast；By step（2）
Processed scion is whittled into section, and length 4cm stays 3 buds, cuts 2 bevels, one is long and the other is short two bevels are respectively 2.0cm and
0.5cm；Then it keeps to the side to cut on stock along cotyledon petiole direction, the scion cut is inserted into immediately, clutches junction, anvil fringe shape
It is layered opposite, so that stock and the forming layer of scion is coincide naturally, it is real to wrap drawing with plastic foil；
（5）Managing after grafting：After grafting survival, the work side shoot on former stock and rudiment of erasing in time are wiped out immediately, is poured on time
Water.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
