Abstract
The present invention relates to seedling growth field, more particularly to a kind of Acacia continma root turion cuttage and seedling culture method；The survival rate of Acacia continma root turion cuttage taken root is set to improve by the improvement of a variety of conditions by the optimization of exogenous hormone condition and the control of dose；Due to semi-lignified fringe bar maturation more more stable than spray fringe bar internal structure, resistance is preferable, and since Acacia continma fringe bar viscosity is low, the present invention is using the higher IAA of concentration as exogenous hormone, pass through spraying time appropriate, the generation for promoting Acacia continma root restriction, enables IAA to promote the synthesis of Acacia continma endogenous hormones and the conversion of nutriment and transport, to have the function that improve the survival rate of Acacia continma root turion cuttage and seedling culture.
Description
Technical field
The present invention relates to seedling growth field, more particularly to a kind of Acacia continma root turion cuttage and seedling culture method.
Background technology
Acacia continma (Acacia cincinnata) bark taupe brown, lobe.Phyllode light green color, elliptic-lanceolate are long
10-16cm, wide 1.5-3cm have three apparent longitudinal veins, and tightly there is sparse silvery white villus on leaf two sides.It is grey to lark, fringe
Locusta, October at florescence, May in next year seed maturity, pod is strip-spiral.This seeds originates in 16-18 ° of Queensland the north
The ground such as Keynes, the frazier island of 25-28 ° of Mai Kai and its south, Brisbane, about between 16-28 ° of south latitude.Roll up pod
Vanguard tree seed of the yearning between lovers as afforestation, the characteristics such as adaptable strong, fast-growing, the excellent, nodule nitrogen fixation of material.In China
The current application amount in Fujian Province is larger.
Seedling is the material base and prerequisite of afforestation, and can accelerate sapling multiplication speed then be relationship forestry hair
An important factor for exhibition.Using high quality tree species nursery, afforestation, there is low risk, less investment, quick, benefit to a certain extent
The advantages that high.But the seedling production cycle it is long, it is of high cost, for just introducing Acacia soon, even more encounter introduces a collection
The nursery stock differentiation of insufficient significant problem, and Acacia, generative propagation is serious.It is numerous with cuttage compared with generative propagation
The clonal offspring grown is less prone to segregation phenomenon, keeps the original merit of Acacia, has yield per unit area
Height, is convenient for the features such as management at forest form is neat, is to obtain maximum Forestry Ecological also in compliance with sexual breeding, the asexual strategy utilized
The means of economic benefit.
Invention content
The technical problem to be solved by the present invention is to：A kind of root turion cuttage and seedling culture method suitable for Acacia continma is provided,
Solve the problems, such as more difficult to take root, conditional instability of taking root present in traditional Acacia continma cuttage and seedling culture method.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of Acacia continma root turion cuttage and seedling culture method, includes the following steps：
Step 1：Forest land is flattened, chesson inside sets gutter；
Step 2：It is laid with seedbed on the forest land of leveling, matrix is laid on seedbed；
Step 3：The semi-lignified fringe bar of Acacia continma maternal plant root turion is cut into the cuttage item of 2-4cm long, tilts 40-60 degree
Cuttage is in seedbed；
Step 4：Acacia continma by cuttage in seedbed is trimmed, and 2-3 full buds are retained；
Step 5：To cuttage in a concentration of 490-510mg/ of Acacia continma sprinkling the exogenous hormone IAA, the IAA in seedbed
The processing time of L, the IAA are 10-20s；
Step 6：It applies fertilizer in the seedbed for having Acacia continma to cuttage, dose is every plant of 1-3g phosphate fertilizer and 1-3g potash fertilizer.
The beneficial effects of the present invention are：In Acacia continma root turion cuttage and seedling culture method provided by the invention, by that will roll up
The semi-lignified fringe bar of pod yearning between lovers maternal plant root turion is cut into the cuttage item of 2-4cm long, using 40-60 degree the cuttage of inclination cuttage in
Seedbed makes Acacia continma root turion skewer by the optimization of exogenous hormone condition and the control of dose by the improvement of a variety of conditions
The slotting survival rate taken root improves；Due to semi-lignified fringe bar maturation more more stable than spray fringe bar internal structure, resistance is preferable, and
Since Acacia continma fringe bar viscosity is low, the present invention uses the higher IAA of concentration as exogenous hormone, when by sprinkling appropriate
Between, promote the generation of Acacia continma root restriction, IAA is enable to promote the synthesis of Acacia continma endogenous hormones and turning for nutriment
Change and transport, to have the function that improve the survival rate of Acacia continma root turion cuttage and seedling culture.
