Description
Technical field
The present invention relates to a kind of efficiently breeding sequoia sempervirens cuttage seedling-growing method.
Background technology
Sequoia sempervirens is that Taxodiaceae sequoia sempervirens belongs to evergreen huge arbor, originates in the mountain region of West Coast North America year, is the world
Precious fast-growing few survivors seeds.Sequoia sempervirens is both excellent commerical tree species, is also graceful landscape seeds.It is world-renowned
Big-diameter wood seeds, growth is rapid, and volume recovery is high, and the excellent long lifespan of material, individual volume can reach 100m3.Sequoia sempervirens tree performance
Grandness, the four seasons are evergreen, and isolated planting or mass-planting in lakeside, lawn are suitable in gardens, and landscape is beautiful, grandeur.
Sequoia sempervirens, which has in very strong sound-insulating and heat-insulating ability, its substantial amounts of cell cavernous structure, is filled with air, turns into
The best timber of thermal insulation effect, effect of heat insulation is considerably beyond brick, cement and steel.Sequoia sempervirens trunk is logical straight satisfactory, raw
Length is tall and straight.Its sapwood is cream color, and durable heartwood is rufous；Wood grain is averaged, and has soft to medium hardness and medium
Intensity, heartwood has good anti-corrosion, protection against the tide, the characteristic of insect prevention with raw；It is odorous during processing；It is easy to combine and hold with paint
Long；Its burr has bright and beautiful orange red, and structure is peculiar, slightly processes just honorable charming.Suitable for especially dry or moist ring
In border, service life is 30 to 50 years.The outstanding physical property of sequoia sempervirens, become valuable senior building and
Thin woodenware material, is widely used in outdoor deck, park structure, veneer, chooses mouth decoration, fence and bench, be also to make each
Plant the ideal material of carving part.
From 1972 introduce China, the research through more than 40 years of scientific worker, sequoia sempervirens Shanghai, Hangzhou, Nanjing,
The ground such as Kunming, Hubei introducing and planting.Years of researches show that not only increment, the speed of growth are higher than existing China master to sequoia sempervirens
Reproducting tree species, such as China fir, larch-tree, cryptomeria are wanted, and its material is also better than above-mentioned seeds.
Sequoia sempervirens uses seed seedling-raising more in actual production, need to be introduced a fine variety by Chinese arboreal seeds branch, and seed
It is expensive.It concurrently there are low percentage of seedgermination, exposed root and shoot forestation survival rate, the low problem of storage rate.So as to cause to be produced into
This height, low production efficiency.Though there are associated mechanisms, expert to carry out seed by harvesting the seed of the successful sequoia sempervirens of introducing and planting
Seedling growth test, but result is unsatisfactory, and germination percentage is extremely low.
In recent years, the paper of sequoia sempervirens cuttage and seedling culture research, data are more.And have sequoia sempervirens cuttage and seedling culture correlation
Patent is produced, but is focused mostly on sequoia sempervirens nursery stock large-scale breeding technology, crooked, inclined with regard to sequoia sempervirens cuttage seeding trunk
Hat, it is slow-growing the problems such as or avoidance or do not explain clear.And afforested using the sequoia sempervirens cuttage seeding of routine techniques,
Afforestation Effects are not also high.It is unfavorable for the popularization of produce reality application.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of efficient breeding sequoia sempervirens cuttage seedling-growing method.
The technical scheme is that：A kind of efficiently breeding sequoia sempervirens cuttage seedling-growing method, it is characterised in that including following
Step：
A. cuttings：Introduced a fine variety with Chinese arboreal seeds branch, the sequoia sempervirens tree seedling of culture, gather 1 year raw sequoia sempervirens
Healthy and strong, I grades of side shoots of no disease and pests harm, remove the radical leaves of 1/2 cuttings length；Then carry out disinfection processing；
B. cuttage seedbed：Select traffic convenience, be easy to irrigation, the plot that physical features is gentle, draining is good, illumination is divulged information；Autumn
Site preparation is carried out after receipts, more than 25cm is ploughed deeply, it is in small, broken bits to turn over rear soil, and removes stone, weeds, grass roots；Carry out disinfection processing；Seedbed
Wide 70-80cm；Surrounding drainage trenching, tap drain depth 30cm, secondary ditch depth 20cm, the wide 40cm of pavement；
C. the preparation of Light media container：With peat soil 60%, perlite 20%, charing husk 15%, fermented rape cake 3%,
Phosphate fertilizer 1%, potash fertilizer 1% are well mixed to form Light media；Light media is filling in the cylindric appearance that specification is 5-6cm × 6-8c m
In device, and neatly closely it is placed on cuttage seedbed, holding container upper cut is smooth, good with earth culture around seedbed, between container
Space is tamped with fine earth, is carried out disinfection；
D. cuttage：An aperture is first pricked with small wooden, depth 3-5cm inserts the cuttings of processing in Light media container, pressure
Real, cuttings is micro- to incline, overlay film heat and moisture preserving immediately after sterilization, removes plastic sheeting mid-April, shading shed screening is taken within 20-25 days after inserting
It is shady；Growth is allowed to, bed is stayed 1 year, during which notes weeding；
E. transplant：Second Year to transplanting at the beginning of 6 months, removes unnecessary coppice shoot by the end of May during transplanting, retain most healthy and strong upright coppice shoot,
One plant one of formation is dry.
It is preferred that, acquisition method used is in step a：Length 6-10cm band terminal bud fringes are trimmed to scissors or grafting knife
Bar, trims smooth, smooth lower cut, ovalisation, without broken skin and splitting；Described sterilization method is：First use 50% carbendazim
500 times of immersions there are not cuttings 30min to carry out disinfection, the rear IAA solution submergence cuttings base portion 1min with 2000mg/L.
It is preferred that, the disinfection treatment method described in step b is：50% Mancozeb 3g/ ㎡, 6% is close up to 1.5g/㎡,
50% phoxim 2g/ ㎡, mix fine earth and spread fertilizer over the fields in soil respectively.
It is preferred that, the water content of the Light media described in step c is 10-15%；Described cylindrical container is used can be certainly
The non-woven fabrics so degraded is made；It with concentration is that 0.1-0.2% potassium permanganate solutions irrigate sterilization that described sterilization method, which is,.
It is preferred that, the method that the sterilization described in step d is used is to dilute 500 times of liquid with 50% carbendazim to irrigate.
A kind of efficiently breeding sequoia sempervirens cuttage seedling-growing method, it is characterised in that comprise the following steps：
A. cuttings：Introduced a fine variety with Chinese arboreal seeds branch, the sequoia sempervirens tree seedling of culture, gather 1 year raw sequoia sempervirens
