Abstract
The invention relates to a method for rapid breaking of Pyrus betulifolia Bunge seed dormancy and promotion of germination. The method comprises the steps of: (1) seed collection and cleaning: collecting the fruits of trees that have unadulterated seed tree variety, grow robustly and are free of diseases and pests; (2) seed soaking in warm water: conducting warm ironing treatment; (3) short-term storage in sand: selecting washed fine sand, watering the sand thoroughly, mixing the seeds and the sand uniformly in a volume ratio of 1:2-3, loading the mixture into a woven bag, then putting the bag into a 0-5DEG C refrigerator or cold storage for 10 days; and (4) germination acceleration technique: taking out the Pyrus betulifolia Bunge seeds, washing the fine sand, at the same time soaking the seeds wet, flatly spreading the clean seeds on cotton cloth evenly to a thickness of not more than 2cm, covering the seeds with cotton cloth, spraying water to the cotton cloth appropriately, maintaining a room temperature, and 2-3 days later when 93% of the seeds start germination, conducting sowing.
Description
Technical field
The present invention is to combine short-term sand at low temperature with water seed soaking to hide quickly breaking dormancy of birch-leaf pear seeds, and the method for presprouting of seeds technology,
Belong to technical field of plant production.
Background technology
The method of existing process birch-leaf pear seed has three classes: a class is to use lamination method breaking dormancy of birch-leaf pear seeds.By seed and wet sand etc.
After wet matters mixing or layering store about 60 days breaking dormancies under conditions of being placed on low temperature, moistening, ventilation, sowing just can be sprouted
Bud.Often seed is often because holding bad moisture, aeration condition or Stratification time during sand is hidden, and easily affects seed proper solution except stopping
Sleep, cause after planting that seed can not germinate or germination percentage is low, even cause seed to go rotten.Stratification duration is long, each department temperature
Humidity difference is big, and lamination environment is not easy to grasp.Seed during sand is hidden often because holding bad moisture, aeration condition or lamination time
Between, easily affect the normal breaking dormancy of seed, cause after planting that seed can not germinate or germination percentage is low, the most mildew and rot.Such as 2014
This processing method is taked in year large area nursery, and more than 90% nursery failure, emergence rate is less than 10%.
Equations of The Second Kind be use Chemical treatment quickly breaking dormancy of birch-leaf pear seeds, as hydroxylamine chloride, sodium nitroprusside, different sulfur guanidine urea,
H2SO4、NaOH、kNO3\H2O2Deng seed soaking, but often with 0.1% mercuric chloride solution soaking disinfection before seed soaking, then use chemical drugs
Agent processes, the most dangerous, in addition it is also necessary to suitable Thermo-Photo sensitive.(patent [publication number]: CN101563969；Patent
Queried for items is numbered: 201010203725；Patent consulting bullets: 201010189755；" seed " 2009 (01)
109-111)
3rd class is low temperature and HORMONE TREATMENT breaking dormancy of birch-leaf pear seeds.Naturally the birch-leaf pear seed of storage 1a is with 1000mg/LGA3
Soak seed respectively 24h with hormones such as 200mg/L6-BA, germination percentage can be significantly improved in conjunction with taking K cryogenic treatment 25d.And to working as
New seed of gathering in year promotes that sprouting effect is the least.And Corticosteroids concentration is the lowest, scientific research uses it is also possible that produce popularization and be difficult to
Grasp." north gardening " 2009 (4) 47-49.
Summary of the invention
In order to solve the problems referred to above, shortening birch-leaf pear seed treatment period, easy and simple to handle as far as possible, is greatly improved breeding efficiency, it is simple to
Production nursery operates, and does not the most damage seed, harmless to human body and seed, production safety.The present invention provides the one of birch-leaf pear seed
Germination accelerating method fast and effectively, improves potentiality of seed, germination percentage, promotes early Seedling, strong sprout, Qi Miao, to solve to produce upper anvil
Wood seed must carry out the problem that long-time cold stratification could be sprouted, and this new method can realize 12 days completing to release stopping
Sleeping, the technical solution used in the present invention is as follows: a kind of quickly breaking dormancy of birch-leaf pear seeds, the method promoting to sprout, including following
Step:
(1) collection of seed and cleaning: after birch-leaf pear seed fully maturation, take that elite stand kind is pure then, robust growth,
Without the fruit of pest and disease damage tree body, compost method is taked in the cleaning of seed, and thickness is 25～30cm, and temperature controls below 30 DEG C,
Often stirring during accumulation, make seed lose vigor in case temperature is too high, sarcocarp is rubbed broken sarcocarp in time and is removed sarcocarp after rotting,
With wet cleaning process, go not plump, roguing, remove brokenly grain, take out seed, make purity reach more than 95%, rinse well with clear water, be placed on room
Interior or shady and cool place dries, and should not be exposed to the sun；
(2) water seed soaking: take lukewarm water to process, selected birch-leaf pear seed goes after the removal of impurity through 55 water seed soakings, is stirred continuously
10min so that it is cooling, then soaks seed 48 hours by normal-temperature water, and the most every 12 hours of period changed 1 water, prevented and treated birch-leaf pear souring
Smelly, remove simultaneously and swim in the flat seed of the water surface, rotten seed, until seed soaking water is so clear that you can see the bottom；
(3) short-term sand is hidden: chooses flushed fine sand, waters permeable, holds with fine sand agglomerating, looses one's grip i.e. to dissipate and is advisable, according to kind
The ratio mix homogeneously of husky volume ratio 1: 2-3, loads in woven bag, is then placed in the refrigerator of 0-5 DEG C or in freezer 10 days,
Often within 3-4 days, stirring once, suitably spraying water when husky surface is dry keeps appropriateness；
(4) Stratification technique: take out birch-leaf pear seed, fine sand is cleaned, seed is soaked simultaneously, by evenly laid out for clean seed
On cotton, thickness is less than 2cm, covers seed with cotton, suitably sprays water to cotton, is maintained at room temperature, seed after 2-3 days
Show money or valuables one carries unintentionally and just can sow up to more than 93%.
Use above technical scheme, compared with prior art, have the advantage that
Birch-leaf pear seed seed soaking+short-term in spring sand Tibetan+germination hastening method is in pear tree seedling raising process, and birch-leaf pear seed uses warm water leaching before next spring sowing
Planting accelerating germination+short-term bag Tibetan, indoor+germination hastening method, ratio sand in winter hides Stratificated treatment, Chemical treatment and hormone-treated method, tool
Have that the cool stratification time is short, can effectively shorten pears seedling raise period, simple efficiently, low cost, easily operation, production safety, go out
The advantages such as bud is neat, avoid seed mildewy.Promote on a large scale in being suitable for producing.
The birch-leaf pear seed of the process of the application present invention, starts rudiment, whole rudiments about a week for after planting 3 days, and germination percentage is high
Reach more than 82%.The present invention release method simply, easily and fast, safety, there is good application and promotion prospect.
