Abstract
The invention relates to a pretreating method for seed of Idesia polycarpa seedling, comprising the steps of soaking the seed of Idesia polycarpa in clean water for 2-5 hours, then soaking in 5-15% sodium bicarbonate solution in 5 hours, adding clean water to knead and wash until wax coat on the surface of seed of Idesia polycarpa being broken, and then soaking the processed seed in clean water for 6-12 hours, sowing the seed in seedbed to cultivate, at last transplanting the seedling in seedling nursery with base fertilizer to cultivate.
Description
Technical field
The present invention relates to the pretreating method for seed that Idesia polycarpa is grown seedlings.
Background technology
Idesia polycarpa (Idesia Polycarpa Var.Vestita Diels) is the mutation that the Flacourtiaceae idesia belongs to, and is deciduous tree.Have speed and give birth to, the water and soil function keeps, and fruit yield is big, oil content is high, advantages such as oil is good, edible.The unsaturated fatty acid content of Idesia polycarpa oil is greater than 82%, linoleic acid content is greater than 68.6%, content of vitamin E is greater than 1 ‰, do not contain poisonous chaulmoogra oil, erucic acid is lower than 0.3% composition such as grade, but the edible oil of its both production high-quality also is the excellent raw material that extracts linoleic acid, vitamin, preparation biodiesel and senior lubricant, is the ecological forest of a kind of better economic.The Idesia polycarpa height of tree reaches 10～15 meters, and the hat width of cloth is big, in natural, ecological is, the good barrier of low layer vegetation, and the root system dense layer is 20～60cm and the intensive one-tenth net of butt coring under the face of land, and is extremely strong to the water and soil conservation of top layer, soil.Its phase of abounding with reached more than 50 years, and the phase single plant yield of abounding with can reach 75kg above (dry fruit), and the dry fruit oil content is more than 38%.The Idesia polycarpa trunk is perfectly straight, is turriform, and the phase of bearing fruit is long, and fruit ruby has ornamental value.Idesia polycarpa is wooden careful, and is not yielding, is rich in toughness but has marrow more crisp easy to break in the branch.Idesia polycarpa has the bigger economic worth and the ecological value, and its development and use have caused scientific research personnel's attention.At present Idesia polycarpa is with mainly being distributed in southern foot, the Qinling Mountains, river, Shan, Gandhi.And all there is growth in all mountain regions of COMPONENT IN SOUTH SICHUAN BASIN, are one of Sichuan indigenous tree speciess.Ten thousand strains white deer town, Pengzhou after Sichuan 5.12 earthquakes last year has planted 20 in the disaster area rebuilds surplus.Idesia polycarpa reproduction rate under natural endowment is lower, and therefore successful seedling-cultivating method mainly contains seed seedling-raising, stem cutting, cuttage and grafting.Grafting is to shorten it to bear fruit the phase with the branch grafting on the Idesia polycarpa treelet of growing up, main purpose, but its treelet depends on seed seedling-raising and root is inserted.Root is inserted and is adopted the Idesia polycarpa tree root to carry out cuttage, can influence the growth of getting the root tree, also depends on seed seedling-raising to a certain extent root is provided.The Idesia polycarpa seed seedling-raising method of having studied mainly contain with washing powder, vegetation buck to seed soak, rubbing, washing go the method for sowing after cured and use KH
2PO
2Reach with sodium bicarbonate solution and soak the method for growing seedlings behind the seed.But the percentage of seedgermination that the former has is not high, and planting percent is also lower; And the latter has the weakness that soak time is long, seedling easily catches an illness.In sum, successful seed seedling-raising method is the key of development and use Idesia polycarpa, and successful pretreating method for seed is the key of seed seedling-raising method.
Summary of the invention
Problem at current Idesia polycarpa seedling-cultivating method exists the objective of the invention is to provide a kind of percentage of seedgermination height, and the seedling rate of catching an illness is low, the pretreating method for seed of the Idesia polycarpa seed seedling-raising that planting percent is high.The object of the present invention is achieved like this: soak the Idesia polycarpa seed with sodium bicarbonate solution, the cured matter layer and the destroyed or processing of oil layer that help its surface by the rubbing washing methods, enter in the seed body thereby help moisture, guarantee seed germination rate.Carbonate ammonia natrium toxicity is lower, can alleviate to the injury of seed with to the potential injury of its seedling, can reduce the incidence of disease of seedling.After its concrete technical scheme is earlier the Idesia polycarpa seed to be soaked 2～5 hours with clear water.Soaked＞0～4 hours in＞5～15% sodium bicarbonate aqueous solution, soaking temperature is＞25～32 ℃.Seed after soaking is crumpled and washed, and rubbing washing degree is that the surperficial cured matter layer of Idesia polycarpa seed is destroyed.Seeds treated is sowed the seedbed again with the clear water immersion again and is carried out seedling culture after 6～12 hours.
With respect to existing method, the sodium composition of seed treatment bicarbonate of the present invention is determined, can effectively be controlled, can guarantee healthy seed germination rate greater than 98%, the seedling incidence of disease is less than 1%, and planting percent is greater than 97%, there is not the limiting factor of growing saplings, carried out large-scale application.
Specific implementation method
Embodiment 1: seed elder generation clear water soaked after 4.5 hours, sodium bicarbonate solution with 6% soaked 20000 (about 17 grams) Idesia polycarpa seeds 3.5 hours for 1 liter, 26 ℃ ± 0.8 ℃ of soaking temperature, add clear water rubbing washing and with behind its surperficial wax damage layer thereafter, soaked 6.5 hours with clear water again, it is sowed in the seedbed, after 40 days, obtain above seedling 19895 strains of 2 true leaves, planting percent 99.5%, also can be transplanted to the compoiste fertilizer that uses market sale does the nursery of base fertilizer and can obtain 1.2～1.5 meters high one-tenth seedling 19789 strains after 8 months, total planting percent 98.9%.
Embodiment 2: seed soaks with clear water earlier that the sodium bicarbonate solution with 14% soaked 10000 (about 8.6 restrain) Idesia polycarpa seeds 0.1 hour for 0.5 liter after 2.5 hours, behind 30 ± 1 ℃ of the soaking temperatures.Add clear water rubbing washing with behind its surperficial wax damage layer, after soaking 10 hours with clear water again, it is sowed in the seedbed, after 40 days, obtain above seedling 9887 strains of 2 true leaves, planting percent 98.8% also can be transplanted to the nursery of making base fertilizer with the compoiste fertilizer of market sale and be obtained 1.2～1.5 meters high one-tenth seedling 9851 strains after 8 months, total planting percent 98.5%.
Claims (1)
1. Idesia polycarpa a kind of pretreating method for seed of growing seedlings, it is characterized in that the Idesia polycarpa seed used after 2～5 hours greater than 5% with the clear water bubble earlier again and soak greater than 0 hour to smaller or equal to 4 hours to sodium bicarbonate aqueous solution smaller or equal to 15% concentration, soaking temperature is extremely smaller or equal to 32 ℃ greater than 25 ℃, seed after the immersion adds clear water and crumples and wash, the rubbing degree is that the wax coat on surface of Idesia polycarpa seed is destroyed, and the seed of handling soaks with clear water again to be broadcast after 6～12 hours into the seedbed cultivation of growing seedlings.
