Abstract
The invention discloses a kind of asexual cuttage breeding method of winterhazel, propose from adopting bar, cutting bed prepares, a whole set of the asexual cuttage breeding method of winterhazel of management after cuttage branch process to cuttage and cuttage, by selecting of the right age branch, suitable plant growth regulator is concentration and processing time extremely, prepare suitable cutting bed etc. and carry out cottage propagation, promote cutting Rapid Rooting, effectively add rooting rate and quality of rooting, this method of operating is simple, do not need technical professional or means, and outfit material price is cheaply easily bought, and cuttage survival rate is high, Be very effective, vegetative propagation for winterhazel provides simple and effective method, there is very strong practicality.
Description
Technical field
The present invention relates to arboriculture technology, especially relate to a kind of asexual cuttage breeding method of winterhazel.
Background technology
Winterhazel belongs to Hamamelidaceae winterhazel and belongs to machaka, China's endemic plant, be distributed in the Yangtze river basin and on the south each province.Winterhazel first spends posterior lobe early spring, and inflorescence is again and again sagging, and gloss is as beeswax, and look is yellow and fragrance is pleasant, mutually sets off that aobvious altogether the garden was gay with bloosoms of every bue with cercis, flowering peach intermingle; Its autumn leaves turns yellow, and slightly dye is purple dizzy, is the excellent ornamental tree species of garden fragrance; The root skin of winterhazel and leaf are containing quercitrin, Bergenin etc., and can be used as medicine and control confusing stupor, be important traditional Chinese medicine.Winterhazel is China's endemic plant, the important view indigenous tree species in Jiangsu Province and characteristic fragrance medicinal plant, but little to the development and research of these seeds for a long time, a small amount of winterhazel is sporadicly distributed in Ning Zhen and raises in low mountains and hills, and germ plasm resource faces exhaustion.
The propagation method of current winterhazel has field transplanting, seed germination etc., but field transplanting method can cause very large destruction to primary border, seed germination method, all should not as the main Reproduction method of winterhazel then due to the inconvenient and output instability of gathering of seed.
Summary of the invention
Goal of the invention: there is instability and to the problem of natural environment compared with havoc to solve in prior art existing current propagation method, the present invention proposes a kind of survival rate high, easy and simple to handle, do not destroy the asexual cuttage breeding method of winterhazel of natural environment.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme: a kind of asexual cuttage breeding method of winterhazel, comprises the steps:
(1) adopt bar: choose the growth age in the growing up of 8-10, robust growth, anosis winterhazel plant is as maternal plant;
(2) cutting bed prepares: cuttage bed is using the thick river sand after being exposed to the sun of 25-35cm as bottom matrix, and matrix does cuttage vessel with forest cave dish, and the river sand after being exposed to the sun is filled up in coiling in cave, takes sunshade measure;
(3) process of cuttage branch: branch is cut into the cuttings that 15-20cm is long, otch is upper flat declivity, and otch lower end distance closes on internode 0.3-0.5cm, often props up cuttings and stays bud or blade 3-4; It is soak 1-2h in the a-methyl α-naphthyl acetate of 100ug/L that cuttage is prepended to mass concentration;
(4) cuttage: select carry out cuttage summer, before cuttage, 2-3d carries out sterilizing to cutting bed, and cutting bed temperature remains on 25-35 DEG C, and the cuttage degree of depth is 6-10cm, and cutting density is 4cm × 6cm; Water immediately after cuttage, within 3rd, water for the second time afterwards, third time watered afterwards on 5th;
(5) management after cuttage: regular watering, diligent weeding, prevents damage by disease and insect.
More preferred, adopting the bar time in described step (1) is 7-9 month.
More preferred, in described step (2), cutting bed surrounding builds up with cement.
In order to ensure the effect of matrix, in described step (2), river sand used is exposed to the sun 1-3d.
Further, sterilizing adopts mass concentration to be that the carbendazim solution of 1g/L carries out in described step (4).
Beneficial effect: the asexual cuttage breeding method of a kind of winterhazel provided by the invention, propose from adopting bar, cutting bed prepares, a whole set of the asexual cuttage breeding method of winterhazel of management after cuttage branch process to cuttage and cuttage, by selecting of the right age branch, suitable plant growth regulator is concentration and processing time extremely, prepare suitable cutting bed etc. and carry out cottage propagation, promote cutting Rapid Rooting, effectively add rooting rate and quality of rooting, this method of operating is simple, do not need technical professional or means, and outfit material price is cheaply easily bought, and cuttage survival rate is high, Be very effective, vegetative propagation for winterhazel provides simple and effective method, there is very strong practicality.
