Abstract
The germination accelerating method for Chinese torreya seed includes collecting mature Chinese torreya seed, eliminating aril, spreading in shade place while maintaining humidity for at most one week, germination accelerating in wet sand layer inside nursery land, covering with short arched plastic shed and high plastic shed, and conventional management. The present invention has one time raised Chinese torreya seed germination ratio, low cost and capacity of cultivating great amount of Chinese torreya stock seedlings.
Description
Technical field
The present invention relates to a kind of germination accelerating method of Chinese torreya seed, particularly a kind of germination accelerating method that heats with the dual plastic greenhouse of height.
Background technology
Chinese torreya (Torreya, grandis ' Merrillii ') is the distinctive rare dry fruit of China, it is the good cultivar that from Chinese torreya (Torreya grandis Fort.ex Lindl.), selects through propagation by grafiting, its dry fruit is through frying, the local flavor delicious and crisp of food, nutritious, also have health care, more than 200 yuan of per kilogram price.And the Chinese torreya (being commonly called as wooden Chinese torreya) of seedling breeding the seed hulls heavily fortified point is thick, meat is thick and stiff, British plain spirits, mouthfeel is poor, price has only 1/5 of Chinese torreya, resource is but abundant than Chinese torreya.Utilize the Chinese torreya planting seed to grow seedlings as the stock of grafting Chinese torreya, there is seed resource to enrich and reduce the benefit of seedling cost, but because of the Chinese torreya seed size differed, differs around the maturing stage nearly one month, the shell of seed is thick, embryo is little, emergence rate is about 40% then with live broadcasting method, can not satisfy the Chinese torreya demand of breeding fast.The commodity economy of China has just been stepped into development track, after Chinese torreya becomes the fruit new lover recently, many researchs with put into practice work and do not catch up with as yet, therefore do not retrieve the report of Chinese torreya presprouting of seeds technology.Traditional way is to adopt the Chinese torreya seed seedling-raising, and because of this seed hulls is thin, uniform particles, germination rate height, with the vernalization of conventional method lamination, germination rate also can reach 80%.In recent years, Chinese torreya seed price is increased sharply, the seedling valency is more surprising, causes the job costs of growing seedlings to heighten, and is restricting the development of Chinese torreya industry.
Summary of the invention
The technical problem that the present invention need solve provides a kind of germination accelerating method for Chinese torreya seed, adopts aboundresources, cheap Chinese torreya seed, improves germination rate by heating the measure of grade of preserving moisture, and the purpose of Chinese torreya rootstock seedling is bred in realization low-costly and in high volume, fast.
The technical scheme that the present invention takes is: collect fully ripe Chinese torreya seed 10, during November, go arillus, spread shady place and preserve moisture, one all inherent nursery lots are with the vernalization of damp sand lamination, cover short arch plastic greenhouse, add and cover tall and big plastic greenhouse vernalization again, during in time check management.
The present invention's technical scheme more specifically is: spread shady place and preserve moisture and be meant and spread thickness≤20cm that the loam cake straw is preserved moisture.The vernalization of damp sand lamination is meant spreads the thick damp sand of 8-12cm on nursery lot, damp sand moisture content 7-9% sprinkles the seed of one deck non-overlapping copies again, and lid layer damp sand again to lose seed degree of being, covers the thick straw layer of 1-2cm topmost above.Seed Layer and the damp sand cover layer on it respectively are the 1-2 layer in the vernalization of damp sand lamination, and are spaced one by one.Short arch plastic greenhouse height is 0.35 ± 0.05m, and the height that adds the tall and big plastic greenhouse that covers is 1.6 ± 0.1m.The emphasis of checking management is in time to build canopy and lift canopy, and with control temperature and gas permeability, watering in time is with controlled humidity, check germination and the time sow in batches.
The present invention changes the custom of traditional employing Chinese torreya presprouting of seeds, the Chinese torreya presprouting of seeds of cheapness with aboundresources, create the special measure that dual plastic greenhouse heats, the Chinese torreya percentage of seedgermination is doubled from 40%, reach 80%, have low-costly and in high volume, breed fast the advantage of Chinese torreya rootstock seedling.
Embodiment
The present invention will now be further detailed embodiment: the comparative test result situation that earlier different plastic foil coverage modes is heated vernalization is listed as follows:
| Germination time | The vernalization measure | Chinese torreya percentage of seedgermination (%) | |||
| Go up sweet forest farm | Exquisite forest farm | Cross road fourth village | On average | ||
| 2001-2003 late October-mid-November | The double-layer plastic canopy | 80.74 | 81.40 | 80.73 | 80.96 |
| The monolayer plastic canopy | 59.40 | 58.04 | 64.00 | 60.48 | |
| 02-03 mid-October | Live film covers | 48.32 | 49.30 | 48.20 | 48.61 |
Last table as seen, the germination rate that the double-layer plastic canopy covers is the highest, the monolayer plastic canopy cover secondly, it is the poorest that live film covers.
Embodiment 1: operate according to the following steps:
(1) preliminary treatment before the vernalization.Every year 10, the fully ripe Chinese torreya seed of choosing between November, with the arillus cracking, that gathers when part comes off is best.Decortication immediately or stacking are no more than a week after adopting, and seed is got in arillus one mashed i.e. peeling, spread at shady place, and thickness 20cm, the loam cake straw is preserved moisture, wet and pile fermentation when doing when avoiding.
(2) nursery lot vernalization.November 15 was taken above-mentioned ready seed to ground, garden in the past, spread the thick damp sand soil of 10cm in the garden earlier, sprinkled seed again, and the zero lap phenomenon covers damp sand soil again, to lose seed degree of being.(soil of the damp sand here moisture content 8%, to have held moist feeling but do not have infiltration and get final product).Upper cover one bed thickness is preserved moisture for the 1.5cm straw, short arch plastic greenhouse on the frame again, and height 0.35m adds and covers tall and big plastic greenhouse, height 1.6m.
(3) check management.The Chinese torreya seed just germinates for 10 ℃, and the differentiation of embryonic development and shoot apex is very fast in the time of 20-30 ℃.The protection of double-layer plastic canopy is arranged, make the vernalization seed be in environment more than 15 ℃.In Zhejiang area, say generally can remove short arched roof March that noon, canopy temperature＞38 ℃ was opened the booth two ends with the ventilation cooling.It is moistening that sand and seed will keep, watering in every month 3-4 time, water-containing rate 8%.
(4) sowing in batches in time.The seed of vernalization success by germinate successively respectively at 2,3, early April sows in batches, seeding quantity is a 90kg/ mu.April is seeds germinated not as yet, no longer germinates then, places indoor stacking, and the lid straw is preserved moisture, and next year remakes vernalization usefulness, the seed that this class remains, and also there is 95% germination rate next year.
Embodiment 2: each step and method of operating are all identical with embodiment 1, and what distinguished is (2) nursery lot vernalization, respectively are two-layer with Seed Layer and the damp sand layer on it that broadcasts sowing, and are spaced one by one.Its advantage is to save plot, shed, is convenient to centralized management; Shortcoming is to have increased management difficulty, and lower floor's percentage of seedgermination is more lower slightly than the upper strata.
Use vernalization of the present invention, Chinese torreya seed average germination percentage about 80%.
