Description
Technical field
The present invention relates to tree cuttage technical fields, and in particular to a kind of Chinese yew old branch high-survival rate cutting propagation side
Method.
Background technology
Chinese yew, also known as Japanese yew, share 11 kinds in the world, and there are taxusyunnanensis, Xizang Taxus chinensis, northeast in China
Chinese yew, five kinds of Chinese Chinese yew and southerm yew, wherein southerm yew category mutation kind.
Wild red bean China fir natural propagation is pecked at japanese yew fruit by bird, and Chinese yew seed is discharged by excrement, after landing also
It need to could germinate by 2 years rest periods, be easy to be eaten by toys such as mouse, squirrels on mountain in the meantime, if do not had
There is the Chinese yew seed pecked at by bird that cannot germinate, so the breeding of wild red bean China fir is slow, and emergence rate is not high, thus
Chinese yew is classified as first-grade state protection plant by country.
Last century the nineties, artificial seed broadcast breeding southerm yew and succeed, and southerm yew is able to large area and pushes away
Extensive farming is planted, but seed is broadcast breeding Chinese yew and had the following disadvantages：First, Chinese yew seed has to pass through the dormancy awakening phase, the period is longer；
Manually the protective layer outside seed is ground second is that Chinese yew has to pass through, is otherwise not easy to germinate, not only time-consuming but also increase cost；Three
It is Chinese yew seed to broadcast sowing in spring in the coming year, and the good temperature and humidity of to master, otherwise seed does not germinate or rots；Fourth, seed is broadcast
Or the method for other cutting propagation Chinese yew is not easy to transplant.Because Chinese yew grows to certain altitude, basin must be transplanted or change,
Seed, which is broadcast, or the Chinese yew of other cuttages is transplanted or changes basin seedling taking must injure Chinese yew if method is improper from soil
Root system influences survival rate；Fifth, the survival rate for broadcasting breeding Chinese yew using seed is not high, it is unable to Rapid Popularization.
Currently, the normal cutting propagation reproduction technique that Chinese yew uses is into artificial propagation, but the overwhelming majority there are survival rates low, training
Educate the problems such as period is long, and cultivation is of high cost, difficult to take root.Even if also some take root and cuttage sprig, spray.It rises
Not much effect.And the cuttage root-taking for the stem thickness of 100 years above Chinese yew of the age of tree in the old branch of 5-10cm is just more difficult to
It realizes.Since Chinese yew density is big, material is hard, is not easy to take root, and has more than 5 centimeters of old branch item and generally takes 2 years and just takes root,
And usually 13-15 or more just can as a result, breeding the time it is long, be unable to Rapid Popularization.
Invention content
Overcome the deficiencies in the prior art of the present invention, it is therefore an objective to which a kind of Chinese yew old branch high-survival rate cutting propagation side is provided
Method.
To achieve the above object, the technical solution adopted in the present invention is：A kind of Chinese yew old branch high-survival rate cuttage is numerous
Method is grown, is included the following steps.
a）The selection of cuttage branch：Select the age of tree in the old branch item of >=50 years elite stands, old branch stem thickness 5-10cm is long
30-40cm；
b）The construction in seedbed：Nursery soil matrix is 1 according to weight ratio by vinegar grain, perlite, plaster, river sand, clinker:2-3:1-
2:1:0.5-0.8 is uniformly mixed and is configured to soil matrix, reuses vinegar and allocates the pH of soil matrix to 4.5-5.5, soil
Water content of substrate should be 60-70%；12-24h is placed, adjusts the temperature of soil matrix at 25-30 DEG C before cuttage.
c）The processing of cuttage branch：Old branch bottom is cut into 60 ° of smooth scarves, impregnates 1-5min with 75% alcohol；
It is impregnated after being configured to aqueous solution with root-inducing powder and airing is spare.
d）By the good nursery soil Medium Culture of the cuttage branch insertion process handled well, cuttage depth is the 1/ of branch length
3。
e）After cuttage, ground temperature is 22-28 DEG C at the deep 5-10cm in seedbed, and temperature of shed is 26-29 DEG C.
Preferably, the weight ratio of root-inducing powder and water is 1：10, the soaking time for amidin of taking root is 5min.
Meanwhile illumination is also needed to control, direct sunlight should be avoided when not taking root also.Branch after cuttage
Top covers sunshade net.Sunshade rate in rooting process is 60-70%.Sunshade rate gradually declines in growth course, until branch at
It lives and gradually removes sunshade net after taking root.
Compared with prior art the invention has the advantages that：The present invention overcomes Chinese yew old branch to not easily pass through skewer
The problem of inserting rooting propagation, by the control to soil matrix composition proportion, acid-base value and the soil moisture, realizes Chinese yew
Old branch, the especially cutting propagation to the old branch of the above Chinese yew 5-10cm stem thicknesses of the century-old age of tree.For soil matrix, select
Vinegar grain and perlite, plaster, river sand, clinker are prepared in proportion, more through containing in the remaining husk decomposition product of everfermentation in vinegar grain
Kind organic substance, trace element and active enzyme component, play facilitation, in addition, vinegar grain in the rooting process of excitation old branch
Characteristic with porosity and looseness itself improves the ventilative of soil matrix entirety during with other compositions mixed preparing
Performance, and very strong heat and moisture preserving is made it have, provide best growing environment for taking root for Chinese yew old branch.Pass through vinegar
The acid-base value for adjusting soil matrix, keeps it under moderate acid environment, is conducive to the work of growth-promoting root tissue and enzyme in old branch
Property, the efficiency of taking root of old branch can be improved, root-inducing powder is used cooperatively, the root survival of old branch is made to significantly improve.Positioned at seedbed
It is the position that cuttage old branch are most sensitive in growth course and metabolism is most fast, keeping constant temperature contributes at deep 5-10cm
Old branch are taken root.The method of the present invention is simple and easy to do, and can greatly reduce cost, and the Chinese yew old branch survival rate of institute's cuttage reaches
80-95%, and can result in cuttage current year.
