Abstract
The invention discloses a seed germination method for idesia polycarpa seedling culture, which comprises the steps of cleaning oil stains on the surfaces of fresh seeds by use of a special detergent for fruits and vegetables; germinating the cleaned seeds in a germination bed.
Description
Technical field
The present invention relates to a kind of seed germinating method of Idesia polycarpa nursery.
Background technology
Idesia polycarpa (Idesia Polycarpa Var.Vestita Diels) is the mutation that 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 ‰, not containing poisonous and harmful element, it is the edible oil of high-quality, is also to extract linoleic acid, vitamin E, the excellent raw material of preparation biodiesel and senior lubricant.The Idesia polycarpa phase of abounding with reaches more than 40 years, and the phase single plant yield of abounding with can reach 200kg (dry fruit), dry fruit oil content 38 ~ 42%.Idesia polycarpa well developed root system, water and soil conservation function is strong.Idesia polycarpa trunk is logical straight, and in Pagoda-shaped, the phase of bearing fruit is long, and fruit ruby has ornamental value.Idesia polycarpa is wooden careful, not yielding, is rich in toughness.Idesia polycarpa has larger economic worth and the ecological value, and it develops the attention having caused researcher.Current Idesia polycarpa is in wild state substantially, is mainly distributed in territory, Guangyuan City, Sichuan Province.Idesia polycarpa reproduction rate under natural endowment is lower, and therefore successfully seedling-cultivating method becomes the key developing Idesia polycarpa resource.The seedling-cultivating method of current Idesia polycarpa mainly contains seed seedling-raising, root is inserted and grafting.Grafting branch grafting on Idesia polycarpa seedling of growing up, main purpose shortens it to bear fruit the phase, but its seedling depends on seed seedling-raising and root is inserted.Root is inserted and is adopted tender of Idesia polycarpa tree to carry out cuttage, can affect the growth of getting root tree, also depend on seed seedling-raising to a certain extent and provide root.The Idesia polycarpa seed seedling-raising method studied mainly contains the method for soaking, crumpling, wash method and the nursery after soaking with biphosphate Potassium solution sowed after removing the surface of the seed wax coat with washing powder, vegetation buck, sodium bicarbonate etc. to seed.The former is time-consuming, and cost is higher, and some percentages of seedgermination are not high, and planting percent is also lower; There is the higher problem of the seedling incidence of disease in the latter.In sum, successful seed seedling-raising method is the key developing Idesia polycarpa, and successfully solves the key that seed sprouting problem is seed seedling-raising method.
Summary of the invention
For current Idesia polycarpa seedling-cultivating method Problems existing, the object of the invention is to find a kind of percentage of seedgermination high, the seedling incidence of disease is low, planting percent is high, the seed germinating method of the Idesia polycarpa seed seedling-raising that cost is low, it is characterized in that the fresh seed taken out from Idesia polycarpa fresh fruit reality to put into clear water in time, with fruit, vegetables special purpose detergent, the greasy dirt of fresh for Idesia polycarpa the surface of the seed is cleaned.The fresh seed of Idesia polycarpa cleaned is put into germinating bed and is germinateed.Germinating bed bottom is plastic foam or other seepy material, and thickness is 1 cm ~ 5cm.Separate with water penetration cloth between the fresh seed of Idesia polycarpa and plastic foam or other seepy material.The fresh seed of Idesia polycarpa cleaned is placed on water penetration cloth, its thickness 0.2 cm ~ 2cm.Control germinating bed temperature 5 DEG C ~ 25 DEG C during the fresh seed sprouting of Idesia polycarpa, and control moisture the fresh Seed Layer of Idesia polycarpa is not born water, surface wettability.The fresh seed major part of Idesia polycarpa enters seedbed after germinateing and carries out seedling culture.
The object of the present invention is achieved like this: germinate with the fresh seed of Idesia polycarpa, avoids the wax coat mummification on Idesia polycarpa surface that the passage of water of seed is closed, thus be conducive to moisture and enter in seed body, ensure the germination rate of seed; The greasy dirt that the fresh the surface of the seed of Idesia polycarpa cleaned by employing fruit, vegetables special purpose detergent can effectively prevent seed from going mouldy during germination, simultaneously fruit, vegetables special purpose detergent toxicity are lower, the injury to seed and the potential injury to its seedling can be alleviated, the incidence of disease of seedling can be reduced.
Relative to existing method, seed germinating method of the present invention is simple, cost is low.Fruit, vegetables special purpose detergent toxicity are lower, and can ensure that healthy percentage of seedgermination is high, the seedling incidence of disease is low, and planting percent is high.The limiting factor of growing saplings is few, is conducive to large-scale application.
specific implementation method
Embodiment 1: enter germinating bed with fruit, vegetables special purpose detergent after being cleaned by 3000 fresh seeds of Idesia polycarpa and germinate.Germinating bed bottom plastic foam thickness is 1 cm, seed layer thickness is 0.2cm, duration of germination control germinating bed temperature 5 DEG C ~ 15 DEG C after .33 days seed major part germinate, it is sowed in seedbed, after 40 days, obtain seedling 2958 strain of more than 4 true leaves, planting percent 98.6%, be transplanted to nursery obtains 1.2 ~ 1.5 meters high seedling 2916 strain after 7 months, total planting percent 97.2%.
Embodiment 2: enter germinating bed with fruit, vegetables special purpose detergent after being cleaned by 50000 fresh seeds of Idesia polycarpa and germinate.Germinating bed bottom river sand thickness is 5 cm, seed layer thickness is 2cm, duration of germination control germinating bed temperature 15 DEG C ~ 25 DEG C after .21 days seed major part germinate, it is sowed in seedbed, after 40 days, obtain seedling 49450 strain of more than 4 true leaves, planting percent 98.9%, be transplanted to nursery obtains 1.2 ~ 1.5 meters high seedling 48850 strain after 7 months, total planting percent 97.7%.
