Abstract
The present invention introduces a breeding method for hairyleaf idesiapolycarpa. Seeds are soaked by 8 to 48 hours in 0.5 to 3% of KH2 PO4 solution, then the seeds are sown into a seedbed for breeding after processing, and young seedlings are transplanted to a nursery garden to be bred into finished seedlings.
Description
Technical field
The present invention relates to a kind of breeding method of Idesia polycarpa.
Background technology
Idesia polycarpa tree (Idesia Polycarpa Var.Vestita Diels) is the mutation that the Flacourtiaceae idesia belongs to, be deciduous tree, it is the woody edible oil plant of high-quality, its oil product unsaturated fatty acid content is greater than 80%, linoleic acid content reaches about 70%, content of vitamin E is greater than 1 ‰, no poisonous and harmful element.Fruit oil content 38～42%.Abounding with the phase (reaching more than 40 years) fruit per mu yield can reach more than the 1800kg.The Idesia polycarpa well developed root system, the water and soil conservation function is strong.Trunk is perfectly straight, is pagoda shape, 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 the Yangtze river basin, but standing crop is also few.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 breeding 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, grafting and root at present.Grafting is to shorten bearing fruit the phase of Idesia polycarpa with the branch grafting on the Idesia polycarpa seedling of growing up, main purpose, but its seedling depends on the seed breeding 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, and the breeding that also depends on seed to a certain extent provides root.The method breeding idesia with hairy leaves of having studied mainly is to adopt washing powder, thin charcoal ash or vegetation buck seed to be soaked, washes by rubbing with the hands the method for sowing after cured.The percentage of seedgermination of these methods is not high, and planting percent is also lower, does not also reach the maturity that engineering is used.
Summary of the invention
Problem at current domestic and international method breeding idesia with hairy leaves exists the objective of the invention is to seek a kind of percentage of seedgermination height, and the method breeding idesia with hairy leaves that planting percent is also high is characterized in that the Idesia polycarpa seed at 0.5～3% KH
2PO
4Soaked seed in the solution 8～48 hours.Seeds treated enters the seedbed and cultivates.In dry seeds, seeding quantity is 0.5～4g/m
2.The soil pH value of bottom, seedbed is 5.0～8.5, and thickness is greater than 10cm.The organic matter that becomes thoroughly decomposed in its surface coverage after the land smoothing, butt consumption are 0～4.5kg/m
2, concrete amount of application is determined according to soil organic matter content.The seedbed draining is good.Seed is sprinkling upon on the organic matter, the organic matter that covers one deck pH above the seed again and be 5.0～8.5 soil or become thoroughly decomposed, and thickness is 1～10mm.Seedling bed temperature before the seed sprouting is 1～25 ℃.The water content in the preceding seedbed of seed sprouting is 20～30%, and the back water content of germinateing is 15～20%.Transplant to the nursery during at least 2 of true leaves of seedling.The seedling spacing in nursery is 5～40cm.
The object of the present invention is achieved like this: 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.
With respect to existing method, seed pretreating agent KH of the present invention
2PO
4Composition determines that can accurately control, thereby can guarantee healthy seed germination rate more than 99%, the seedbed planting percent is greater than 95%, and the limiting factor of growing saplings on a large scale is few, is beneficial to large-scale application.
Specific implementation method:
Embodiment 1: the KH with 1%
2PO
4Solution 2L soaked the 200g Idesia polycarpa 24 hours, and broadcasting into soil thickness is the 200m of 20cm
2The seedbed in, soil pH value 6.5～6.7 is used the house refuse 1000kg that becomes thoroughly decomposed (in butt, comprising bed course and cover layer), 5～20 ℃ of seedling bed temperatures, the preceding seedbed of seed sprouting water content 22～25%, the back water content 16～18% of germinateing.Obtain 4 above seedling 41881 strains of true leaf after 45 days, planting percent 96.8% is transplanted the nursery by strain spacing 30 * 30cm and is obtained high one-tenth seedling 39787 strains of 1.2～1.5m after 7 months.Embodiment 2: use 1.5%KH
2PO
4Solution soaking 5kg Idesia polycarpa 30 hours is broadcast into 2000m
2Seedbed on the spot in, soil pH value 6.2～6.5 is used the plant remains 8000kg that becomes thoroughly decomposed (in butt, comprising bed course and cover layer), 2～25 ℃ of seedling bed temperatures, the preceding seedbed of seed sprouting water content 20～28%, the back water content 15～18% of germinateing.Obtain 6 above seedling 1,040,000 strains of true leaf after 2 months, planting percent 96.2% is transplanted the nursery by strain spacing 20 * 20cm and is obtained high one-tenth seedling 990,000 strains of 0.4～1.2m after 7 months.
