Description
Technical field
The invention belongs to breeding plant technical field, is related to a kind of rare Woody flower Cyclobanopsis chungii seedling and breeds skill
Art, specifically, it is related to a kind of Cyclobanopsis chungii seed equilibrium breaking dormancy and sprout cultivating method.
Background technology
Cyclobanopsis chungii (Prunus campanulata Maxim), for the rose family, it is subordinate to deciduous tree, is distributed widely in
The provinces and regions such as Fujian, Zhejiang, Guangdong, osmanthus, platform, it is to be bloomed in all oriental cherries earliest, pattern one kind the richest and the most gaudy, at the beginning of last month of spring in winter, after first spending
Leaf, full-blown flowers are completely set, charming colourful, are afforded a magnificent spectacle, and occasionally also show floral leaf with putting, light green leaflet sews full end of the branch, Wan Ziqian with fresh flower
Red, spring's colours fill the garden, and ornamental value can be with Tokyo oriental cherry (C.yedoensi, also known as someiyoshine), weeping branch morning cherry
(C.subhirtella var.pendula) etc. compares favourably, very popular, is widely used in the gardens of south China
Make in scape.
Cyclobanopsis chungii belongs to the seed of physiology and strong dual hibernation feature, and one side Cyclobanopsis chungii seed is harvesting
When embryo not yet full maturity (when exocarp is changed into cherry fruit maturation), latter stage of ripening (1-2 months) need to be undergone
Can germination；On the other hand, even if the Cyclobanopsis chungii seed after latter stage of ripening also because its exosper longitudinal direction opposite joint is close and hard,
Moisture is not easy to immerse, and preventing seed, the impermeable stratum (strong exosper) of the seed causes the dormancy of seed from imbibition.This
Outside, the Cyclobanopsis chungii seed sowing nursery through vernalization, easily influenceed to cause uneven emergence by extraneous factor, and then caused
The seedling growth differentiation of seedling raising process is serious.At present, open report breaks the side of Cyclobanopsis chungii seed dormancy and seeding and seedling raising
Method mainly has：With adopt with broadcast, refrigerate autumn sowing, refrigeration springs sowing, the autumn sowing of alternating temperature sand storage, alternating temperature sand storage are sowed in spring, air-dry autumn sowing, air-dried spring
Broadcast, a variety of methods such as sand storage autumn sowing, sand storage are sowed in spring, but utilize air-dry autumn sowing, air-dry sow in spring, sand storage autumn sowing and sand storage are sowed in spring
Method germination percentage is below 50%, and using with adopting with the method germination percentage broadcast less than 80% and emergence is extremely irregular, use is cold
Though hide the germination percentage of autumn sowing and alternating temperature sand storage autumn sowing method needs the duration to be up to more than 30 days up to 80-90% but germination, hair
Bud is uneven to cause seedling growth differentiation seriously, and qualified seedling outplanting rate is low；Sowed in spring using refrigeration and alternating temperature sand storage spring seeding method goes out
Though bud rate is up to more than 95% but causes growing-seedling period to extend 1 year.Therefore, to avoid seedling raising process from incurring loss, hair is ensured
Bud rate is high and seedling growth is neat, improves high-quality seedling outplanting rate, is badly in need of research in production quickly and Cyclobanopsis chungii is broken in equilibrium
Seed dormancy and the mature technology of nursery, so as to the high-quality seedling of amount reproduction, carried for city and Rural Afforestation and landscape renovation
Rise and precious famous-brand and high-quality nursery stock is provided.
The content of the invention
In order to solve technical problem present in prior art, the invention provides a kind of equilibrium of Cyclobanopsis chungii seed to beat
Broken dormancy and sprout cultivating method, it is that a kind of can significantly improve germination percentage and the Cyclobanopsis chungii seed of emergence rate is broken not
The method for culturing seedlings of dormancy, sprout cultivating and transplanting.Its technical scheme is as follows：
A kind of Cyclobanopsis chungii seed equilibrium breaking dormancy and sprout cultivating method, comprise the following steps：
The first step：Seed collection processing
The fully ripe Cyclobanopsis chungii fruit of cerise is changed into by bluish yellow color to the first tenday period of a month in May, collection pericarp by the end of April every year
It is real, pericarp, pulp are removed, decontamination and the seed of agensis is rinsed with clear water, cleans and dry in the shade.As not having to temporarily, polybag is used
It is stored refrigerated standby at a temperature of 3-5 DEG C；
Second step：Seed disinfection is sterilized with basking seeds
The seed of preceding step is soaked seed 60 minutes with 0.3% liquor potassic permanganate, is then washed with water to colourless；Seed is put again
Put and uniformly spread out and be exposed to the sun 40-60 minutes under 20-30 DEG C of sunlight (at 10 points in the morning at 3 points in the afternoon of fine day), seed it is hard
Packed up during longitudinal opposite joint elder generation distal process point fine fisssure of kind skin, then carry out vernalization processing.Hereafter as not having to temporarily, with polybag in 3-
It is stored refrigerated standby at a temperature of 5 DEG C；
3rd step：Breaking dormancy and vernalization
The seed of preceding step and moisture content are sufficiently mixed dress basket or dress for 18-25% washing river sand in 1 ︰ 3~4 ratio
Bag, be stored in 2-5 DEG C of temperature, relative humidity 90-95% controlled atmosphere preserving fruit and vegetable utilizing freezer in 70~80 days, sift out whole seeds,
Cross clear water, drained and standby；
4th step：Sprout cultivating
The seed of preceding step is poured into and is covered with 10 layers or so fully drenched newspapers (or 5 layers or so points of drenched cottons) porous
In pallet, tile 3-5 layer seeds, then covers 10 layers or so fully drenched newspapers (or 5 layers or so points of drenched cottons), then
The pallet for cultivating tooth seedling is fitted into polybag, be filled with air, tightens sack, continues to be stored in 2-5 DEG C of temperature, relative humidity 90-
In 95% controlled atmosphere preserving fruit and vegetable utilizing freezer, after 30~40 days, for germination percentage up to more than 95%, height of seedling reached 2-3cm.
5th walks out of transplantation of seedlings
The sprout of preceding step is transplanted in the Light media nutrient bag through sterilizing (4.5~5.5) × 10cm and continues to cultivate.
Compared with prior art, beneficial effects of the present invention：
1st, the sun is basked seeds, and is caused hard kind skin fine fisssure, is made the easy imbibition of seed.
2nd, germination percentage is high, budding is neat, and seedling stage breaks up less, and high-quality seedling rate is high, is easy to scale seedling raising.
3rd, traditional germination accelerating method germination is uneven, and sprout transplanting wants frequent founding heap, picks sprout, wastes time and energy.
4th, low-temperature germination, suppresses the generation of various moulds, and loss of seeds is few.
