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, soaking in 3-7% KH2PO4 solution in 7.5 hours at the temperature more than 25-32 DEG C, adding clean water to knead and wash after soaking, and then soaking the processed seed in clean water for 4-8 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, and the height of tree reaches 10～15 meters.It is the woody edible oil plant of high-quality, and unsaturated fatty acid content is greater than 82% in its oil, and linoleic acid content reaches more than 68.6%, and content of vitamin E is greater than 1 ‰, no poisonous and harmful element.The fruit oil content is more than 38%, but both production high-qualitys edible oil can extract linoleic acid again, and vitamin still prepares the first-class raw material of biodiesel and senior lubricant; Its root system dense layer 20～60cm and reticulating under the face of land, the phase of abounding with reached more than 50 years, and the fruit per mu yield can reach more than the 1500kg.The Idesia polycarpa well developed root system, the water and soil conservation function is strong.Trunk is perfectly straight, is turriform, and fruit ruby has good ornamental value.Wood grain is careful, and is not yielding, hard and be rich in toughness.Idesia polycarpa is in wild state at present substantially, mainly is distributed in southern foot, the Qinling Mountains, river, Shan, region such as sweet.And all there is growth in all mountain regions of hills, Sichuan and basin, in 5.12 earthquake-stricken areas, Sichuan rebuild, have planted more than 20 ten thousand strains in Pengzhou white deer town especially.
Idesia polycarpa has bigger economic worth, the ecological value, and its development and use have caused researcher's attention.Yet Idesia polycarpa reproduction rate under native state is lower, and therefore, its seedling-cultivating method becomes the key of development and use Idesia polycarpa resource.It is slotting that the breeding method of Idesia polycarpa mainly contains seed breeding, stem cutting, grafting and root at present.Grafting is to shorten Idesia polycarpa to bear fruit the phase with the branch grafting on the Idesia polycarpa treelet of growing up, main purpose, but its treelet depends on the seed breeding 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 the seed breeding to a certain extent root is provided.The Idesia polycarpa seed breeding method of having studied mainly adopts washing powder, the sub-liquid of oil trouble, thin charcoal ash or vegetation buck and river sand processing etc. that seed is soaked, washes by rubbing with the hands the method that cured matter layer is sowed.It is not high that these methods are handled percentage of seedgermination, and planting percent is also lower, easily catches an illness again, more can not reach the maturity of engineering application aims and large-scale production.
Summary of the invention
Problem at the above-mentioned seedling-cultivating method of current domestic and international Idesia polycarpa 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.Realization the objective of the invention is to use KH
2PO
4Soak the Idesia polycarpa seed, guarantee that moisture content can enter in the seed body smoothly, guarantees that again seed preserves from, thereby can realize seed germination rate.According to the achievement in research to the Idesia polycarpa growth rhythm, the seedling phase keeps enough organic matters, both can effectively adjust seedling bed temperature, can guarantee the nutrient component demand of seedling again, thereby can guarantee to cultivate the strong sprout that can transplant to the nursery.
Technical scheme of the present invention is earlier the Idesia polycarpa seed to be soaked 1～4 hour with clear water, again at＞3～7% KH
2PO
4Soaked soaking temperature＞25～32 ℃ in the solution＞0～7.5 hours.Seed after the immersion adds clear water rubbing and washing, and the degree of rubbing is that the cured matter layer of Idesia polycarpa the surface of the seed is destroyed; The seed of handling soaked 4～8 hours with clear water again, broadcast into the seedbed cultivation of growing seedlings.After going out seedling, can transplant, carry out strong seedling cultivation to being the nursery of base fertilizer with commercially available composite fertilizer.
With respect to existing method, seed treatment KH of the present invention
2PO
4Composition determines that can accurately control, the seedling planting percent in seedbed is greater than 98%, and the limiting factor that the incidence of disease＜1% and scale are grown saplings is few, is beneficial to sizable application.
Specific implementation method
Embodiment 1: the Mao Yeshan paulownia after 10000 in seed (about 8.5 grams) soaks 3.5 hours with clear water earlier, the KH with 3.1%
2PO
41 liter of solution soaked 6 hours, with clear water washing and the rubbing cured matter layer degree of being with damaged the surface of the seed.It is standby that clear water soaks after 4 hours seed again.The seedbed is gone in the seed uniform broadcasting of handling well, and after 60 days, 2 true leaf seedling have 9875 strains, and planting percent 98.7% is transplanted to the nursery of making base fertilizer with commercially available composite fertilizer and can be obtained 1.2～1.5 meters treelet 9697 strains, planting percent 96.9% after 10 months.
Embodiment 2: after Idesia polycarpa seed 5000 (about 4.1 grams) steeps 1 hour with clear water earlier, and the KH with 7%
2PO
4Solution soaked seed 1.5 hours for 0.5 liter, added clear water and rubbing to destroy the surface of the seed wax coat, soaked 8 hours with clear water again.The seed of handling is evenly broadcast in the seedbed, obtains 2 above seedling 4921 strains of true leaf after 2 months, and planting percent 98.4% is transplanted to high treelet 4831 strains of acquisition 1.2～1.5m when doing the nursery to ten month of base fertilizer with commercially available composite fertilizer, planting percent 96.6%.
Claims (1)
1. pretreating method for seed that Idesia polycarpa is grown seedlings is characterized in that Idesia polycarpa seed seed earlier with clear water bubble 1 hour to 4 hours, use again greater than 3% to equal, KH less than 7%
