Abstract
The invention discloses a balance dormancy breaking and seedling cultivation method of cerasus campanulata seeds. The method comprises the following steps: collecting and treating the seeds, namely, soaking the seeds in a 0.3% potassium permanganate solution for 60 minutes, and then washing the seeds with water until the seeds are colorless; evenly spreading out the seeds under the sun at the temperature of 20-30 DEG C from 10 A.M. to 3 P.M. in a sunny day, exposing to the sun for 40-60 minutes, putting away the seeds when the longitudinal seam apex acuminate of hard seed coat has tiny crack, and then treating by accelerating germination; breaking dormancy and accelerating germination, namely, fully mixing the seeds with washed river sand having the water content of 18-25% according to the ratio of 1: (3-4), then putting the mixture into a basket or a bag, and storing in an air-conditioning fruit and vegetable fresh-keeping refrigeration house having the temperature of 2-5 DEG C and the relative humidity of 90-95% for 70-80 days; carrying out seedling cultivation. The method for breaking dormancy as well as culturing and transplanting seedlings of the cerasus campanulata seeds is capable of remarkably improving the germination rate and the emergence rate, thus being suitable for popularization and application.
Description
Technical field
The invention belongs to breeding plant technical field, relate to a kind of rare Woody flower Cyclobanopsis chungii seedling raising technology, specifically, relate to the balanced breaking dormancy of a kind of Cyclobanopsis chungii seed and sprout cultivating method.
Background technology
Cyclobanopsis chungii (Prunus campanulata Maxim), for the rose family, be subordinate to deciduous tree, be distributed widely in Fujian, Zhejiang, Guangdong, osmanthus, the provinces and regions such as platform, bloom the earliest in all oriental cherries, the one that pattern is the richest and the most gaudy, at the beginning of last month of spring in winter, first spend posterior lobe, full-blown flowers are completely set, charming colourful, afford a magnificent spectacle, occasionally also show floral leaf with putting, light green leaflet and fresh flower sew full end of the branch, rich in variety, spring's colours fill the garden, ornamental value can with Tokyo oriental cherry (C.yedoensi, also known as someiyoshine), weeping branch cherry morning (C.subhirtella var.pendula) etc. compares favourably, very popular, be widely used in the Landscape of south China.
Cyclobanopsis chungii belongs to the seed of physiology and strong dual hibernation feature, on the one hand Cyclobanopsis chungii seed embryo not yet full maturity of (when exocarp changes cherry fruit maturation into) when gathering, need experience latter stage of ripening (1-2 month) could germinate; On the other hand, even if the Cyclobanopsis chungii seed going through latter stage of ripening is also because the longitudinal opposite joint of its exosper is tight and hard, moisture not easily immerses, and makes seed can not imbibition, and the impermeable stratum (strong exosper) of this seed causes the dormancy of seed.In addition, through the Cyclobanopsis chungii seed sowing nursery of vernalization, the impact being easily subject to extraneous factor causes emerges uneven, and then causes the differentiation of the seedling growth of seedling raising process serious.At present, the method that open report breaks Cyclobanopsis chungii seed dormancy and seeding and seedling raising mainly contains: with adopting with broadcasting, refrigeration autumn sowing, refrigeration is sowed in spring, alternating temperature sand hides autumn sowing, alternating temperature sand is hidden and is sowed in spring, air-dry autumn sowing, air-dry spring sowing, husky Tibetan autumn sowing, the multiple methods such as husky Tibetan spring sowing, but utilize air-dry autumn sowing, air-dry spring sowing, the method germination rate sowed in spring in husky Tibetan autumn sowing and husky Tibetan is all below 50%, adopt and emerge extremely irregular with the method germination rate broadcast less than 80% with adopting, though the germination rate adopting refrigeration autumn sowing and alternating temperature sand to hide autumn sowing method can reach 80-90%, but germinateing needs the duration to reach more than 30 days, the uneven seedling growth that causes that germinates breaks up seriously, qualified seedling outplanting rate is low, though the bud ratio adopting refrigeration spring sowing and alternating temperature sand to hide spring seeding method can reach more than 95% but cause growing-seedling period to extend 1 year.Therefore; incur loss for avoiding seedling raising process; ensure that germination rate is high and seedling growth is neat; improve high-quality seedling outplanting rate; production is badly in need of research fast and the mature technology of Cyclobanopsis chungii seed dormancy and nursery is broken in equilibrium; thus amount reproduction high-quality seedling, for city and Rural Afforestation and landscape renovation provide precious famous-brand and high-quality nursery stock.
Summary of the invention
In order to solve the technical problem existed in prior art; the invention provides the balanced breaking dormancy of a kind of Cyclobanopsis chungii seed and sprout cultivating method, be a kind of can significantly improve germination rate and emergence rate Cyclobanopsis chungii seed breaking dormancy, sprout cultivating and transplanting seedling-cultivating method.Its technical scheme is as follows:
The balanced breaking dormancy of a kind of Cyclobanopsis chungii seed and sprout cultivating method, comprise the following steps:
The first step: seed collection process
Annual by the end of April to the first tenday period of a month in May, gather pericarp and change the fully ripe Cyclobanopsis chungii fruit of cerise into by bluish yellow look, removing pericarp, pulp, with clear water rinsing decontamination and obsolete seed, clean and dry in the shade.As temporarily need not, for subsequent use by plastic sack stored refrigerated at 3-5 DEG C of temperature;
Second step: seed disinfection sterilization with bask seeds
The seed of front step 0.3% liquor potassic permanganate is soaked seed 60 minutes, then washes with water to colourless; Evenly spread out under again seed being placed on 20-30 DEG C of sunlight be exposed to the sun 40-60 minute (point at 10 in the morning to afternoon 3 in fine day), pack up during longitudinal opposite joint first distal process point fine fisssure of the hard seed coat of seed, then carry out vernalization process.After this as temporarily need not, for subsequent use by plastic sack stored refrigerated at 3-5 DEG C of temperature;
3rd step: breaking dormancy and vernalization
Be that the washing river sand of 18-25% fully mixes in the ratio of 1 ︰ 3 ~ 4 and fills basket or pack by the seed of front step and moisture content, be stored in temperature 2-5 DEG C, in the controlled atmosphere preserving fruit and vegetable utilizing freezer of relative moisture 90-95% 70 ~ 80 days, sift out whole seed, cross clear water, drain for subsequent use;
4th step: sprout cultivating
The seed of front step is poured in the pallet being covered with about 10 layers fully drenched newspaper (or about 5 layers are divided drenched cotton) porous, tiling 3-5 layer seed, then about the 10 layers newspapers fully drenched (or about 5 layers are divided drenched cotton) are covered, again the pallet cultivating tooth seedling is loaded in plastic sack, is filled with air, tightens sack, continue to be stored in temperature 2-5 DEG C, in the controlled atmosphere preserving fruit and vegetable utilizing freezer of relative moisture 90-95%, go through 30 ~ 40 days, germination rate reaches more than 95%, and height of seedling reaches 2-3cm.
5th walks out of transplantation of seedlings
To continue in the bud transplantation of seedlings of front step to the Light media nutritious bag through sterilizing (4.5 ~ 5.5) × 10cm to cultivate.
Compared with prior art, beneficial effect of the present invention:
1, the sun is basked seeds, and causes hard seed coat fine fisssure, makes the easy imbibition of seed.
2, germination rate high, sprout neat, seedling stage breaks up less, and high-quality seedling rate is high, is convenient to scale seedling raising.
3, traditional germination accelerating method germinates uneven, and bud transplantation of seedlings is wanted frequent founding heap, picked bud seedling, wastes time and energy.
4, low-temperature germination, suppress the generation of various mould, loss of seeds is few.
