Abstract

The invention relates to a pregemination method for the seeds of Euscaphis konishii, which is characterized in that, firstly, a layer of river sand is arranged in a room or an air permeable vessel; the water content of the river sand is no more than 5%, and the thickness of the river sand ranges from 5cm to 10cm; then a layer of seeds with a thickness of about 2cm is arranged; then a layer of river sand with a thickness of about 5cm is arranged; according to the method, the seeds are arranged in sequence. The stratification height is nor more than 40cm to 50cm; during the sand storaged process, except for winter, seeds are sieved by a screen every 15 days, and obviously bad seeds are eliminated; then the water content of the sand is adjusted to 4% to 5%, and the seeds are storaged in sand as before; after around 150 days, the seeds begin to break; when the breaking seeds are around 10%, the seeds are sieved and sown. The pregemination method for the seeds of Euscaphis konishii has the advantages that, the germination rate of sowing is above 75%, and the invention is suitable to be applied to production.

Description

Euscaphis konishii seed accelerating germination method

Technical field

The invention belongs to the cultivation method of economic forest, particularly relate to medicinal, ornamental plants euscaphis konishii seed accelerating germination method.

Background technology

Euscaphis konishii (Euscaphis konishii Hayata) is the evergreen dungarunga of the wild crow Toona of Staphyleaceae, but the seed oil soap system; Bark can be made tannin extract; Root, really warm in nature, mildly bitter flavor.Dispel rheumatism, hemostasis and pain-relieving, delivering looses trembles with fear.The radical cure puerperal fever, traumatic injury.Fruit is controlled testiclar gall, the prolapse of uterus.Euscaphis konishii has the effect of seeing flower, seeing leaf and reward fruit, ornamental value height.Fruit-growing time is long, from the late September exocarp fruit abscission in March in next year that reddens, sees fruit for up to half a year, and red gorgeous blind pod has increased many celebrating colors to autumn and winter season, makes the people intoxicated.Euscaphis konishii is as ornamental tree species, applied range, but mass-planting, group planting also can be used for ground setting such as flower garden, park in the lawn.But because the seed of euscaphis konishii has deep dormancy, from collecting seed insemination and emergence span 3 years, and emergence rate is low, in order to obtain higher percentage of seedgermination and more healthy seedling, must carry out sand Tibetan vernalization to seed; 2006 the 3rd phases " Jiangxi forestry science and technology " have been delivered " preliminary treatment of euscaphis konishii seed and seedling growth rule and Study on Seedling Cultivation Technique " article, it adopts the new method of " after the seed collecting; taking-up seed; wet sand storage (when sowing in spring to next year); make its kind epithelium matter softening; the promotion seed afterripening is also soaked seed (1 kilogram of seed is converted 1.5kg hot water) with 65 ℃ of-68 ℃ of hot water, sows behind the cooling 24h naturally " before sowing.Can make its germination rate bring up to 51%-65%.Office of Fujian China project achievement trade fair organizing committee has delivered the technical need of Sanming City Min Yuan Bioceuticals Inc. " 618 review " total 25 phases (2007 the 5th phases).The technical need explanation: the said firm intends 10,000 mu of euscaphis konishii planting bases, be badly in need of a large amount of seedlings, present natural seedling is few, generally take artificial seed to broadcast type of rearing, hard because of wild crow Chinese toon seed shell, be difficult for to germinate, be seeded into to emerge more and generally reach one-year age from broadcasting seed, how to make and broadcast seed and shorten to 2-3 month to the time of sprouting, and guarantee that bud ratio reaches more than 70%.Be badly in need of in the production wanting germination rate at the germination accelerating method more than 70%.

Summary of the invention

The purpose of this invention is to provide a kind of seeding and seedling raising germination rate at the germination accelerating method more than 75%.

Method of the present invention realizes as follows: the husky Tibetan of a kind of euscaphis konishii seed method its at the bottom of wooden case or underground flooring, putting the about 5-10cm of a bed thickness earlier, contain amount of moisture 4-5% (can be agglomerating when promptly pinching with hand, hand looses into several after decontroling) river sand, sprinkle a bed thickness 2cm left and right sides seed then, spread the thick river sand of the about 5cm of one deck again, method has been hidden seed successively, and last layer river sand is thick to be 5cm, and the lamination height is no more than 50cm; In the process of husky Tibetan, except that winter,, sift out seed, remove obviously bad seed, adjust the water content of sand, remain on 4-5%, hide according to former state is husky then with sieve every 7-15 days; After about 450 days, seed begins breach, when treating that the breach number reaches 10% left and right sides, promptly sifts out sowing.

Adopt the inventive method to carry out vernalization, overcome the deep-sleep that the euscaphis konishii seed exists, germination rate well up to more than 75%, growing way, form after surviving are good.

The invention will be further described below in conjunction with embodiment.

Specific embodiment

Embodiment 1:

Get the euscaphis konishii seed, use a wooden case, put the river sand that contains moisture 5% thick about 10cm earlier.Sprinkle the seed about a bed thickness 2cm then, spread the about 5cm river sand of a bed thickness again, method has been hidden seed successively.Last layer is a river sand.The lamination height is no more than 50cm, in the process of husky Tibetan, every 15 days, sifts out seed with sieve except that winter, removes obviously bad seed, then the water content of sand is adjusted to 4-5%, hides according to former state is husky; Through about 150 days, seed begins breach, when treating that the breach number reaches 10% left and right sides, promptly sifts out sowing.

Claims

1, euscaphis konishii seed accelerating germination method, it is at the bottom of wooden case or underground flooring, put the about 5-10cm of a bed thickness earlier, contain the river sand of amount of moisture 4-5%, sprinkle the seed about a bed thickness 2cm then, spread the thick river sand of the about 5cm of one deck again, method has been hidden seed successively, and last layer river sand is thick to be 5cm, and the lamination height is no more than 50cm; In the process of husky Tibetan, except that winter,, remove obviously bad seed, adjust the water content of sand, remain on 4-5%, then, hide according to former state is husky every 7-15 days; After about 450 days, seed begins breach, when treating that the breach number reaches 10% left and right sides, promptly sifts out sowing.
