Abstract
A kind of method of dalbergia odorifera softwood cutting propagation, comprising the following steps: step 1: it is 70%-75%, humidity 85%-90% that closed greenhouse-environment requirement, which is light transmittance,；Step 2: clip cutting length is 4-5cm, retains 2 compound leaf growing points；Step 3: cutting medium selects perlite and peat earth mixtures；Step 4: cuttage will be carried out after the quickly dipped 1 ‰ ABT1 solution of cuttings；Step 5: the young plant that will take root, which migrates in bulk container, to be cultivated.The advantage is that effectively improve dalbergia odorifera shoot cutting rooting rate and survival rate by the control to the factors such as cuttage environment, cuttings processing, cutting medium and disinfection, expands for child care dalbergia odorifera fine individual plant germ plasm resource and clone cuttage and numerous provide technical guarantee.
Description
Technical field
The invention belongs to plant cuttage propagation field more particularly to a kind of methods of dalbergia odorifera softwood cutting propagation.
Background technique
Dalbergia odorifera, also referred to as Huanghua Pear, and narra, Door frame, ferreous mesua and claim the big name of ancient Chinese four wooden.Now it is
Chinese Second Class Key Protected Plant.Numerous for the germ plasm resource of child care fine individual plant and clone cuttage expansion, various regions research institution is in " dalbergia wood
Yellow wingceltis cutting propagation technology " is though be able to success in research, and survival rate is lower, so being not yet widely applied.
Summary of the invention
To solve the above problems, the present invention provides, one kind is easy to operate, low in cost, take effect a kind of significant dalbergia odorifera
The method of softwood cutting propagation.
To achieve the above object, it is addressed by following technical proposals: a kind of side of dalbergia odorifera softwood cutting propagation
Method, comprising the following steps:
Step 1: cuttage environmental factor is arranged in closed greenhouse, light transmittance 70%-75%, periodically spraying to keep the humidity to be
85%-90%；
Step 2: the processing of cuttings clip selects cuttage branch for semi-lignified middle and upper part；
Step 3: cutting medium selection, cutting medium are perlite and peat earth mixtures；
Step 4: HORMONE TREATMENT carries out cuttage after cuttings is dipped in 1 ‰ ABT1 solution；
Step 5: the young plant that will take root, which migrates in bulk container, to be cultivated.
Further, the cutting length of clip is 4-5cm in step 2, retains 2 compound leaf growing points, most on compound leaf protect
3-4 piece leaflet is stayed, remaining is cut.
Further, the volume ratio that perlite is mixed with peat soil in step 3 is 1:1, keeps higher gas permeability.
Further, the particle slow release fertilizer of every cubic metre of mixed-matrix addition 3-4kg, is loaded using the seedling culture hole plate in 50 caves
Matrix is arranged in the seedbed of wide 1.2-1.4m, is sterilized 1 day with the totally-enclosed close plastic shed of 3 ‰ liquor potassic permanganates.
Further, cuttings is dipped in cuttage after 1 ‰ ABT1 solution continue 5-10 seconds, is inserted into base by the cuttage process of step 4
Half branch in matter.
Further, the selection of time of cuttage is in month in spring 4-5.
Further, take root young plant transplant time in October current year.
Further, watering is combined to carry out disinfection after cuttage, 7-10d alternately applies 600 times of 50% carbendazol wettable powder
1000 times of liquid of liquid or 30% hymexazol.
The invention has the beneficial effects that: technical solution of the present invention is applied, by cutting time, cuttage environment, cuttings
The control of the factors such as processing, cutting medium significantly improves dalbergia odorifera shoot cutting rooting rate and survival rate, and ratio of taking root mentions
Rise 60%-80% or more.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
A kind of method of dalbergia odorifera softwood cutting propagation, comprising the following steps:
Step 1: closed greenhouse is selected, light transmittance 70%-75% is periodically spraying to keep humidity for 85%-90%, when people enters
Sultry sense of discomfort is had, takes root for cuttage strain and control environment is provided.
Step 2: selecting cuttage branch for semi-lignified middle and upper part, and the cuttings branch length of clip is 4-5cm, retains 2
Compound leaf growing point；
Step 3: cutting medium selection, cutting medium select perlite and peat earth mixtures；The peat soil content of organic matter can be high
Up to 60% or more, perlite is loose ventilative, and rotten the case where will not occur in peat soil because of airtight in such cuttings.
Step 4: cuttage carries out cuttage after cuttings is dipped in 1 ‰ ABT1 solution, is inserted into Medium Culture half branch.
A kind of method of dalbergia odorifera softwood cutting propagation, the cuttings branch of clip are branch semi-lignified middle and upper part, most
On compound leaf retain 3-4 piece leaflet, remaining is cut.
A kind of method of dalbergia odorifera softwood cutting propagation, the volume ratio that perlite is mixed with peat soil in step 3 are 1:
1。
The mixed-matrix of a kind of method of dalbergia odorifera softwood cutting propagation, every cubic metre of perlite and peat adds 3-
The particle slow release fertilizer of 4kg loads matrix using the seedling culture hole plate in 50 caves, the seedbed of wide 1.2-1.4m is arranged in, with 3 ‰ permanganic acid
The totally-enclosed close plastic shed of potassium solution sterilizes 1 day.
Cuttings is dipped in 1 ‰ ABT1 solution and held by a kind of method of dalbergia odorifera softwood cutting propagation, the cuttage process of step 4
At once cuttage after continuous 5-10 seconds will all inhibit root by contrasting data it is found that ABT1 solution concentration is too low or long soaking time
System's growth.
A kind of method of dalbergia odorifera softwood cutting propagation, the selection of time of cuttage is in month in spring 4-5.Experiments have shown that 5
The rooting rate of spring in month cuttage is 83%, higher than the rooting rate 79% of Autumn Cutting in November.It should be noted that when Autumn Cutting
Ambient humidity should be reduced to 75%-80%, reduce rooting rate to prevent root-rot.
The step of a kind of method of dalbergia odorifera softwood cutting propagation, spring cuttage five takes root young plant transplanting should be in current year 10
In month, the young plant of taking root of Autumn Cutting is transplanted should be in second year 3-4 month.Root system well-grown at this time, when selecting successive cloudy days
It migrates in bulk container.
A kind of method of dalbergia odorifera softwood cutting propagation combines watering to carry out disinfection after cuttage, and 7-10d is alternately applied
1000 times of 800 times of liquid of 50% 600 times of carbendazol wettable powder liquid or 50% thiophanate methyl wettable powder or 30% hymexazol
Liquid.
Contrasting data:
By contrasting data it is found that using heretofore described technical solution, cuttage root-taking ratio, which has, to be obviously improved, and is promoted
Ratio is about 60%-80%.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms, therefore no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
