Description
Technical field
the present invention relates to a Plants asexual reproduction method, be specifically related to a kind of red maple cuttage breeding method.
Background technology
Acer palmatum (Acer paimatum) calls refined maple, is Aceraceae Acer L, is ornamental tree species famous and precious in urban look.Originate in Yangtze River in China basin, also there is distribution in Japan, the Korea peninsula.China is mainly distributed in Yangtze river basin each province, is born in below height above sea level 1200m mountain region, the border on hills or sparse woods more.Shank Acer defoliation small arbor, height is 8m about, bark Dark grey, annual shoot purple or pale purple green; Perennial branch light gray, purple or darkviolet.Shank mapler leaf is to life, and diameter 7-10 centimetre, base portion cuts shape, palmate drastic crack, sliver 5-9, and usual 7 split, sliver ovum shape Long Circle or drape over one's shoulders pin, and the sharp point in top or long sharp point, there is irregular heavy sawtooth at edge, the close raw pubescence of tender leaf.Blade is first red rear green in spring, becomes red to autumn.Corymb top is raw, blooms after foliation, flower aubergine.Samara is just aubergine, and be brown color after ripe, nutlet is spherical, diameter 7 millimeters, and vein is remarkable; Wing and nutlet long 2-2.5 centimetre altogether, wide 1 centimetre, flare up obtuse angle.May at florescence, really September phase.
Acer palmatum warm, the humid climate of happiness and half cloudy environment, intolerant to waterlogging, more drought-enduring, to subject to day bright evil summer in the isolated planting of direct sunlight place; Suitable be born in fertile, moistening and draining is good soil, cold resistance is not strong, acid, neutral and calcareous soil all can adapt to, because it has high ornamental value, to the performance of urban look, there is considerable effect, the figure of local its grace that is seen everywhere such as Middle Isolated Grassland of Highway, park, square, greenbelt in little residential region is the excellent ornamental tree species competitively cultivated in recent years.
Red maple (Acer palmatum ' Sangokaku ') is one of Acer palmatum gardens variation kind, originates in Japan, China can in the middle part of north to Xinjiang, South Liaoning, reach Hunan in the south, Jiangxi, Northern Sichuan Province grow in region.Red maple is defoliation small arbor, plant height 3.5-4.5 rice, and limb takes on a red color throughout the year, leaf and size like Acer palmatum, young leaves milk yellow, summer is yellow green, and autumn, blade presented magnificent gold, winter blade to the greatest extent after limb the representing coral red of dazzling the eyes.Red maple is widely used in little flower garden and Landscape, can isolated planting, and winter and pure white are avenged in vain and mutually set off, and have much temperament and interest.
At present, red maple, based on seminal propagation, be unfavorable for the Rapid Popularization application of improved seeds, and the nursery stock of seminal propagation differs greatly, and can not keep maternal good characteristic.For expanding the reproduction coefficient of elite plant strain as early as possible, expand sapling multiplication quantity, cottage propagation is a kind of effective technological means, and the Technique on Cuttage Propagation of red maple, also there is not relevant report at present.
Summary of the invention
namely object of the present invention is to overcome the deficiencies in the prior art, provides a kind of and can keep the red maple cuttage breeding method of one that maternal merit, reproduction speed are fast, survival rate is high, simple to operate, practical.
The object of the invention is to be achieved through the following technical solutions: a kind of red maple cuttage breeding method, it comprises the following steps:
S1. cutting time: annual April ~ August;
S2. cutting medium and sterilization: the cutting medium of red maple is perlite; Before cuttage, the wettable powder of carbendazim 500 with 80% or 800 times spray cutting medium, ensure that matrix uses after irrigating rear plastic mulching 2 ~ 3d; Before cuttage, with clear water, flushing is carried out 2 ~ 3 times to matrix, poison in case too much disinfectant produces cuttings; Wherein, described scissors and bucket are that the alcohol of employing 75% has carried out spray disinfectant;
S3. adopt fringe: in the cloudy day or morning, dew was not dry time carry out adopting fringe, choose the red maple elite stand of robust growth, with scissors clip, raw rugosity is 0.3 ~ 0.8cm branch is then fringe bar, and the fringe bar of clip is put into the bucket that clear water is housed; Described scissors and bucket are that the alcohol of employing 75% has carried out spray disinfectant;
S4. cuttings is prepared: the fringe bar scissors removing the tender part of taper children is cut into the short fringe that length is 8 ~ 12cm, and the top clip of cuttings is truncate, bottom clip 30-45 °, apart from joint 0.5cm; Cuttings lower blade all cuts off, and top retains 2 ~ 3, blade, the cuttings made is put into the bucket moisturizing that clear water is housed;
S5. cuttings sterilization: the wettable powder of carbendazim with 80% 700 ~ 800 times soaks the two ends of cuttings, uses clean water 2 ~ 3 times after soaking 5 ~ 10min, removes the carbendazim that cuttings is residual;
S6. HORMONE TREATMENT: after the cuttings base portion moisture after to be cleaned is slightly dry, cuttings base portion is immersed in 3 ~ 4h in the IBA solution of 580 ~ 620mg/L;
S7. cuttage: first draw slotting with sterile glass bar or thin waddy, then the cuttings after HORMONE TREATMENT is inserted in matrix, cuttage spacing in the rows 2 ~ 3cm, line-spacing 4.5 ~ 5.5cm, the cuttage degree of depth 2 ~ 3cm, when cuttings is inserted in matrix, should conveniently by real; Should water immediately after cuttage, to ensure that cuttings base portion fully contacts with matrix;
S8. management after inserting: adopt full-automatic spraying system, during cuttage root-taking, keeps relative air humidity 80 ~ 95%, air themperature 25 ~ 28 DEG C, intensity of illumination 5000 ~ 8000LX; In order to prevent cuttings from rotting, every 7 ~ 10d spray disinfectant agent 1 time after cuttage, just can carry out, until nursery stock stops spray disinfectant agent after all taking root after spraying must be stopped between the lights; Wherein, described disinfectant is wettable powder of carbendazim 700 ~ 800 times of solution of 80%;
S9. transplant: cuttings cuttage 18 ~ 23d starts to take root, can above pot transplanting after 60d.
The invention has the beneficial effects as follows: red maple cuttage breeding method of the present invention, cutting plantation reaches more than 85%, and transplanting survival rate can reach 80%.The inventive method has can keep the advantage that maternal merit, reproduction speed are fast, survival rate is high, simple to operate, practical, on red maple good seed vegetative propagation is produced, has important using value.
