Advantage: contrast with common nursery: cultivate Flos Osmanthi Fragrantis commercial seedling, Flos Osmanthi Fragrantis is few and be difficult to obtain because of seed, and grafting is also undesirable, survival rate is low, and easily cause disease pest infected wound, do into log at any time dead, therefore multiplex cottage propagation, wherein with epicormic branch cutting, draw materials conveniently, operate simple and easy, survival rate is high, particularly educates commercial seedling, instant effect, reclaim old soon, the advantages such as economic turn around time is short.

Detailed description of the invention

The following is embodiment:

1, cutting time should carry out in mid-May to mid-July and mid-September to mid-October. Now new branch top stops growing, and branch is more containing nutrient, and its separate living tissue meristematic capacity is relatively strong, and proper temperature, easily takes root after cuttage simultaneously.

2, the light loamy texture that the seedbed of cuttage prepares to select previous crops to be Oryza sativa L. is ploughed with making garden. Seedbed select and around other plant away from being not less than 250 meters, to avoid disease pest to infect, forbid using animal fertilizer, animal barnyard manure. It is fertile for adopting woodsy fertile soil on mountain, increases the permeability of soil, easily stores moisture simultaneously, sterilizing with fenaminosulf after collecting fertile soil, consumption to be asked for by operation instruction, after handling well, mixing in the soil being mixed in seedbed, consumption ensures every square meter 8-15 kilogram. Taking bedside 120cm, height of bed 25cm, furrow width 40cm, before cuttage, soil treatment is in small, broken bits, bed surface is smooth, raceway groove is unimpeded, soil degree in small, broken bits reaches without the granule big more than Semen Viciae fabae. Put up from plastic film shed high for bed surface 50cm above seedbed, plastic film shed is put up from bed surface 180cm high again, make the cool canopy of transmittance 35%, adopt commercially available plastic material or become cloudy canopy with mountain grass, Caulis et Folium Oryzae bedding.

3, cutting collection growth selection is vigorous, and the elite plant without pest and disease damage is scion-seed tree, and the twig of the raw then semi-lignified of the outer upper part of its tree crown of clip does scion, this is because select such branch to do the cutting of cuttage, having interests shade blastogenesis root, vitality is strong, and survival rate is high. To cutting by thickness situation do range process, base portion bag with wet toilet paper, both moisture-heat preservations, prevent again pathogenic bacteria from attacking; It is bundled into handle again, kills the virus again with agricultural streptomycin 300 after taking back indoor.

4, cutting processes and fringe bar is cut into 8-10cm length, and it retains the 2 pieces of blades cutting off half; Upper end is cut into flat mouth, and base portion is whittled into inclined-plane, is bundled into the wisp of 8-12 strain, by soaking 2 hours in No. 1 ABT rooting powder solution being partly submerged in 5 �� 105 naphthalene acetic acids or 1 �� 10-4 of below base portion 3cm, then takes out cuttage.

5, after cuttage operation diameter size fractionation, same seedbed, the cutting of cuttage ad eundem, not enough when inserting one, also on seedbed one section of cutting cuttage at the same level, it is simple to later management. With the seeding row spacing of 5 �� 10cm, first with the thick peg woods such as cutting jack on seedbed, then cutting bottom 2/3 is inserted in the hole, compress the soil around cutting. Finally irrigate seedbed 1 time with the carbendazim aqueous solution of 0.01%, carry out soil disinfection and water supply moisturizing.

6, management 6.1 after inserting, spray water and shade: observing when drying without the globule and bed soil in plastic film shed, moisturizing of should spraying water in time. Cool canopy above plastic film shed, it is desirable to cover morning and take off evening; In plastic film shed, relative humidity should be maintained at more than 85%, and temperature controls at 18-30 DEG C. If temperature drift, humidity are too small, can pass through to remove overcover and increase water spray to be adjusted; If temperature is on the low side, humidity is excessive, the measure closing canopy film and minimizing water spray can be adopted to be controlled.

6.2, spray medicine and loosening the soil: combine water spray, sprayed the carbendazim aqueous solution 1 time of 5 �� 10-4, to prevent cutting bacterial infection from causing cortex to rot every 7 days. Often to note seedbed soil layer situation, it has been found that the phenomenon that hardens occurs, nursery soil will be loosened in time, avoid having moved cutting root simultaneously, to keep the permeability that soil is good, it is prevented that cutting young root rots.

6.3, bud picking and fertilising: cutting base portion rudiment must be erased in time, to reduce nutrient consumption. In conjunction with water spray, every carbamide spraying 0.2% in 10 days or potassium dihydrogen phosphate 1 time, to promote cutting root system and young sprout growth.

6.4, scaffold dismantling with transplant the summer insert October can remove cool canopy, nursery, next spring transplantation land for growing field crops; Autumn sowing can remove cool canopy in spring in next year, transplant early summer in nursery, land for growing field crops.

No matter being that the Flos Osmanthi Fragrantis Seedling inserted with autumn sowing in the summer all can stay bed 1 year, winter next year, height of seedling reached 30-50cm, can go out garden field planting or move garden cultivation.
