A kind of cultural method of southern magnolia
Technical field
The invention belongs to stock growing field, it is more particularly related to the cultural method of a kind of southern magnolia.
Background technology
Southern magnolia is Magnoliaceae aiphyllium, leaf heavy leather matter floral white fragrance, the moistening rich soil of happiness.It enjoys the favor of people with its tall and straight form, the dark green blade of light, very large pure white flower.In Landscape Application, the tree-like grace of southern magnolia, spending big and fragrant, leaf is abundant and gloss, for characteristic ornamental tree species and flower garden seeds, while be again the green tree species of factories and miness.Optimum is to planting or avenue system before building in flower garden, and imposing manner is magnificent.Scattered planting in lawn or shade tree or tree in flakes of planting can be used as.The cultural method of southern magnolia also exists the problem that resistance is poor and pest and disease damage is serious at present.
Summary of the invention
Problem to be solved by this invention is to provide the cultural method of a kind of southern magnolia.
To achieve these goals, the technical scheme that the present invention takes is:
The cultural method of a kind of southern magnolia, comprises the steps:
(1) seed collection
Select to grow adult stock tree normal, the most ripe, without pest and disease damage in annual JIUYUE to collect seed, then with 0.4-0.6%NaOH solution seed is removed seed coat, and rinse with tap water and become neutral to washing liquid, then dry in the shade in indoor;
(2) the storage of seeds
First being carried out disinfection by sand with the potassium permanganate of concentration 0.2-0.4%, be then layered by the sand of seed and sterilization and be placed in container, be put in indoor, afterwards routine observation sand humidity, and sprinkle water, the frequency of described observation is 1-3 day/time;
(3) selection in seedbed
Seedbed should select smooth in physical features, transportation condition is convenient, soil layer is deep, sunny, labour is sufficient, water source and the good plot of irrigation condition, the water level that superlatively descends in described plot must not exceed 150 cm, and the thickness of the layer is no less than 50 cm;
(4) preparation of Nutrition Soil
Selecting Nutrition Soil to do growth furrow, furrow width 1.2-1.5 m, furrow long 8-10 m, the surrounding of furrow makes ridge;
(5) alms bowl processed
During dress alms bowl, making bowl height consistent, dress alms bowl is from the beginning of one end of long furrow;
(6) sowing
Bowl water after sequencing 1-3 time permeable, until water ooze lower after in each nutritive cube, put the southern magnolia seed that 1-3 grain sand is hidden, sow 1 layer of fine earth of bonnet, soil layer is that 0.4-0.6 cm is thick, and the surrounding at furrow spreads soil simultaneously, then waters 1 water with watering can, finally inserting ledge film, surrounding is compacted;
(7) seedbed management
As southern magnolia young plant Ye Pingzhan, after at 10 in the morning, practice Seedling to ventilating before at 16 in afternoon, after practicing Seedling 1-3 d, gradually take off film, taking off 3-5 d thinning after film, every alms bowl stays 1 Seedling, goes to cut off or to cut off during Seedling, it is sure not to lift seedlings conveniently, the seedbed prevention and control of plant diseases, pest control should be carried out simultaneously
(8) transplant
Carry out transplanting afforestation by the nursery stock forming side root, and carry out liquid manure and pest management.
Preferably, described step (2) carries out before the storage of seeds admix kerosene or zinc phosphide processes.
Preferably, in described step (3) before nursery to seedbed disinfection.
Preferably, the disinfectant disinfected described in consists of ferrous sulfate 160-200kg/hm2, phoxim insecticide 40-50kg/hm2。
Preferably, what described step (4) Middle nutrition was native consists of rural area soil, cinder ash, river sand, perlite, chicken manure, corn cob and Pericarppium arachidis hypogaeae.
Preferably, the proportioning of described Nutrition Soil is 0.5:0.5:0.5:0.5:1:1:0.5-1:1.5:1:1:1.5-1.5:1.
Preferably, described Nutrition Soil carries out uniform spray disinfectant with the KMnO4 solution of 0.05-0.15% after being made in proportion, then uses Furadan parasite killing, uses after piling up 6-8 days.
Preferably, described step (5) spreads plant ash and Furadan on long furrow.
Beneficial effect: the invention provides the cultural method of a kind of southern magnolia, carry out admixing kerosene before described the storage of seeds or zinc phosphide processes, the Mus worm destruction to seed can be reduced, to seedbed disinfection before described nursery, the survival rate after nursery can be improved, the composition of described Nutrition Soil and proportioning, the stem that can make southern magnolia slightly increases slightly, innovation number increases and reduces dead arm number, improve the resistance of plant, described on long furrow, spread plant ash and Furadan, subterranean pest-insect and beneficially lifting can be prevented and treated.Using this kind of cultivation method southern magnolia out have good stress resistance and grow excellent advantage, market potential is huge, has a extensive future.
