The invention discloses a cutting seedling method of cornus stolonifera. The key technology steps of the method include seedbed preparation, matrix blending, soil sterilizing, cutting slips selecting and cutting, root promoting, cuttage and sterilization, film mulching temperature control and moisture retention, management after cuttage and seedling transplanting. By means of the method, the vegetative propagation survive rate of the cornus stolonifera is remarkably improved, the cuttage survival rate reaches to above 92%, qualified seedlings are cultivated to the hilt on the premise of limited seedling growing field and seedling quantity through careful cultivation and effective management, the seedling cost is lowered, and the seedling raising efficiency is increased.
Description
Technical field
The present invention relates to a kind of cuttage and seedling culture method of the volt Lai wood of laying down, belong to achievements in forest-tree seedling propagation technique field.
Background technology
On Plant Taxonomy, the volt Lai wood of laying down belongs to Cornaceae (Cornaceae) Lai wood and belongs to (Cornus), is machaka.The leaf celadon, branch is red, high 90～120cm.Brightly yellowish white, often open in late spring or summer morning.5～June of florescence, drupe, white.Originate in Nevada ,Usa mountain range to Xi Sijiyou, Te Linidi, New Mexico and Alaska and Canadian Newfoundland.Domestic and foreign literature shows, this kind form grace, with luxuriant foliage and spreading branches in leafy profusion is seen flower summer, appreciated fruit autumn, and strong adaptability is the fine tree species of afforestation and water and soil conservation, also is the excellent material of weaving industry.China northeast once had on a small quantity in the eighties in last century introduces a fine variety, and has begun small size in northeast, the North China of China and plant experimentally.2010, the volt Lai wood 5kg that lays down is introduced in the Nanjing from the east coast of the united states, carried out the seed propagation test, cultivate seedling 50,000 strains, and its biological property and ecological habit carried out system research, showing and laying down that the growth of volt Lai wood is vigorous, attitude is gorgeous that it is obvious to view and admire characteristic, and drought resisting, cold-resistant, be worth large-area applications to be promoted.
Compare with seed propagation, vegetative propagation can keep maternal good characteristic, has again growth soon, seedling characteristics early.Existing document is reported seldom the research of Lai wood class sapling multiplication, only there is concise and to the point description in Technique on Cuttage Propagation report to the volt Lai wood of laying down, and survival rate is not high yet, this brings certain limitation for the expansion cultivation of producing at present upper these trees, is badly in need of proposing a kind of easy, cheap, effective asexual reproduction method and satisfies Production requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cuttage and seedling culture method of the volt Lai wood of laying down.By the application of the method, cuttage rooting is fast, survival rate is high, accomplishes under the prerequisite of the limited soil of growing seedlings, limited kind of bar quantity, cultivates to greatest extent qualified seedling, reduces seedling cost, improves breeding efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of cuttage and seedling culture method of the volt Lai wood of laying down, it comprises the steps:
(1) prepare in the seedbed: soil is meticulous to be ploughed deeply, and removes the foreign material such as grass roots, stone and plastics;
(2) soil disinfection: the soil cuttage need be carried out soil disinfection in front 10～20 days, and the soil disinfection matrix that rough sand, pcnb and loess mixing are made in namely using is finished sterilization; Matrix evenly is dispersed on the seedbed, thickness 2～3cm, with running water wetting drench rear stand-by;
(3) plugged ear is chosen with cutting and cut: choose growth 1 year livings branch vigorous, semi-lignified and make plugged ear, keep spike length 5～6cm during intercepting, be with 2～3 buds, otch is smooth, the upper bud 1cm of upper cut distance, and lower cut is apart from lower bud 0.5cm;
(4) urge root to process: 50 of the fringe bars after will intercepting are tied into handle together, soak in running water 6～12 hours first, put into root-growing agent again and soak the degree of depth 2～3cm 6～12 hours;
(5) cuttage and sterilization: the plugged ear after will processing is untied cuttage on the complete slotting machine of in advance sterilization, adopts the straight cutting method, and embedded depth is 1/3～1/2 of cutting length, density 2cm * 4cm, thoroughly spray sterilization with thiophanate methyl solution after cuttage is finished, require to spray evenly, do not stay the dead angle;
(6) overlay film: on the seedbed, set up the film canopy with plastic sheeting for farm use after the sterilization, the high 45～50cm of canopy, length is decided according to seedbed length; Plugging the bow pole on the seedbed every about 1 meter supports; Lay complete rear overlay film sealing wait bending pole, sand is buried in both sides, and water spray irrigates again; 1 Hygrothermograph is respectively put in film canopy both sides, and temp. and humidity changes in the canopy to observe;
(7) temperature control moisturizing and sterilization: keep temperature of shed to change at 25～35 ℃, humidity is more than 70%; For regulating subenvironment in the canopy, set up movable cool canopy with sunshade net, light transmittance 50%～80%, height 1.8～2.4cm, the every day of sunshade during 9:00～16:00; Sprayed sterilization once with thiophanate methyl solution in per 7～10 days; Length 10～15cm crack at film ceiling end with blade every 1.5 meters during sterilization; Mister head is inserted from seam, and rotary nozzle evenly sprays bactericide; Sterilization finishes with adhesive tape sealing to be sealed, and treats to reopen when sterilizing next time use;
(8) seedling replanting: treat that the plugged ear root takes root, can transplant the land for growing field crops more than the long 6cm of average root.
In the step (1), described soil disinfection matrix is the pcnb (C with middle rough sand, 70wt%
6Cl
5NO
2) wetting powder and loess in mass ratio 1:1:9 be mixed with and obtain.
In the step (4), described root-growing agent prepares as follows: indolebutyric acid (3-IBA) 200～400mg and methyl α-naphthyl acetate (NAA) 50mg are dissolved in the ethanolic solution of 20～40ml95 (v/v) %, add again sucrose 20～30mg, potassium permanganate (K
2MnO
4) 0.5～1mg, be dissolved in water to 1kg, make after stirring.
In step (5) and the step (7), described thiophanate methyl [1,2-two (3-carbometoxyl-2-ghiourea group) benzene] solution is prepared as follows and is obtained: be watered the 800g stirring with 70wt% thiophanate methyl wetting powder 100g and form.
Beneficial effect: the cuttage and seedling culture method of a kind of volt Lai wood of laying down that the present invention proposes, drawn the successful practice in the Technique on Cuttage Propagation document, and prepare in matrix, the root-growing agent allotment, plugged ear intercepting and processing, the links such as slotting rear management are bold in innovation and are improved, and have significantly improved the survival rate of cuttage survival rate and seedling replanting.This method is easy to operation, has that cost is low, efficient is high, and easily the advantage such as popularizations has important application and promotional value in the production of the wooden class sapling multiplication of Lai.
