Abstract
The invention discloses a seed treatment method for raising seedlings of Idesia polycarpa. The method comprises the following steps: soaking seeds in 0.3-0.5% sodium bicarbonate aqueous solution for 4-48h; kneading and cleaning the soaked seeds and raising the seedlings with the treated seeds on a seedbed.
Description
Technical field
The present invention relates to a kind of method for treating seeds 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.The unsaturated fatty acid content of Idesia polycarpa oil is greater than 80%, and linoleic acid content is greater than 70%, and content of vitamin E is greater than 1 ‰, do not contain poisonous harmful components, it is the edible oil of high-quality, also is to extract linoleic acid, vitamin E, the excellent raw material of preparation biodiesel and senior lubricant.The Idesia polycarpa phase of abounding with reached more than 40 years, and the phase single plant yield of abounding with can reach 200kg (dry fruit), dry fruit oil content 38～42%.The Idesia polycarpa well developed root system, the water and soil conservation function is strong.The Idesia polycarpa trunk is perfectly straight, is pagoda shape, 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.Idesia polycarpa has the bigger economic worth and the ecological value, and its development and use have caused researcher's attention.Idesia polycarpa is in wild state substantially at present, mainly is distributed in Guangyuan City zone, Sichuan.Idesia polycarpa reproduction rate under natural endowment is lower, and therefore successful seedling-cultivating method becomes the key of development and use Idesia polycarpa resource.The seedling-cultivating method of Idesia polycarpa mainly contains seed seedling-raising at present, root is inserted and grafting.Grafting is to shorten it to bear fruit the phase with the branch grafting on the Idesia polycarpa seedling of growing up, main purpose, but its seedling depends on seed seedling-raising and root is inserted.Root is inserted and is adopted tender of the Idesia polycarpa tree 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, the method sowed after cured is gone in rubbing, washing and with the method for growing seedlings after the biphosphate Potassium solution soaking.The former percentage of seedgermination is not high, and planting percent is also lower; There is seedling incidence of disease problem of higher in the latter.In sum, successful seed seedling-raising method is the key of development and use Idesia polycarpa, and successful method for treating seeds is the key of seed seedling-raising method.
Summary of the invention
Problem at current Idesia polycarpa seedling-cultivating method existence, the objective of the invention is to seek a kind of percentage of seedgermination height, the seedling incidence of disease is low, the method for treating seeds of the Idesia polycarpa seed seedling-raising that planting percent is high, it is characterized in that the Idesia polycarpa seed was soaked in 0.3～5.0% sodium bicarbonate aqueous solution 4～48 hours, soaking temperature is 3～25 ℃, and the seed after the immersion is crumpled and washed, and rubbing washing degree is that the surperficial wax coat of Idesia polycarpa seed is destroyed.Seeds treated enters the seedbed and carries out seedling culture.
The object of the present invention is achieved like this: soak the Idesia polycarpa seed with sodium bicarbonate solution, it is destroyed by the rubbing washing methods to help its surperficial wax coat, enters in the seed body thereby help moisture, guarantees seed germination rate; Sodium bicarbonate 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.
With respect to existing method, seed treatment sodium bicarbonate composition of the present invention is determined, can accurately be controlled, toxicity is low, can guarantee healthy seed germination rate greater than 99%, and the seedling incidence of disease is less than 2%, planting percent is greater than 96%, and the limiting factor of growing saplings is few, helps large-scale application.
Specific implementation method
Embodiment 1: the sodium bicarbonate solution with 0.8% soaked 50 gram Idesia polycarpa seeds 24 hours for 0.5 liter, wash it behind surperficial wax damage layer through rubbing, it is sowed in the seedbed, after 45 days, obtain above seedling 10524 strains of 4 true leaves, planting percent 97.3% is transplanted to the nursery and is obtained 1.2～1.5 meters high one-tenth seedling 10395 strains after 7 months, total planting percent 96.1%.
Embodiment 2: the sodium bicarbonate solution with 2% soaked 10 gram Idesia polycarpa seeds 48 hours for 0.2 liter, wash it behind surperficial wax damage layer through rubbing, it is sowed in the seedbed, after 45 days, obtain above seedling 2124 strains of 4 true leaves, planting percent 98.2% is transplanted to the nursery and is obtained 1.2～1.5 meters high one-tenth seedling 2092 strains after 7 months, total planting percent 96.7%.
Claims (1)
1. method for treating seeds that Idesia polycarpa is grown seedlings, it is characterized in that the Idesia polycarpa seed was soaked in 0.3～5.0% sodium bicarbonate aqueous solution 24～48 hours, soaking temperature is 3～25 ℃, seed after the immersion is crumpled and is washed, rubbing washing degree is that the surperficial wax coat of Idesia polycarpa seed is destroyed, and seeds treated enters the seedbed and carries out seedling culture.
