Abstract
The invention provides a cuttage and propagation method of a twig of cyclocarya paliurus, which comprises the following steps: (1) cutting trunks and promoting the germination of a scion seed tree from the middle ten days of March to the middle ten days of April; (2) cutting a semi-lignified twig as a cutting spike from the first ten days of June to the first ten days of August, wherein the length of the twig is 10cm to 15cm, 5 to 6 small leaves are remained at the upper part of the twig, and the lower end of the twig is cut into oblique section; (3) dipping 500mg/L to 800mg/L of paste-like root growing agent of indolebutyric acid at the positions of 3cm to 4cm of the lower end of the cutting spike; (4) inserting the cutting spike in a light substrate consisting of carbonized pine bark and sawdust, wherein the cuttage depth is 4cm to 5cm; and (5) shading the cutting spike by a black sunshade net with the shading degree of 50% to 70% after the cuttage, and spraying and moisturizing the cutting spike by adopting an intermittent spraying method. 60 days after the cuttage, the rooting rate reaches over 80%. The method is simple and practical to operate and is suitable for large-scale cuttage; seedlings can effectively keep the excellent inherited characteristics of the seed tree; moreover, the effect of the quick vegetative propagation of improved seeds can be achieved.
Description
Technical field
The present invention relates to a kind of twig cottage of cyclocarya paliurus propagation method, belong to the plant asexual multiplication technology field.
Background technology
Blue or green money willow is the distinctive autogenus plant of China, integrate medicinal, health care, material with and various value such as view and admire, be a kind of have develop and the seeds of exploitation prospect very much.Existing natural stands sporadicly is distributed in remote, thickly forested mountains and some nature reserves.Still adopt seed natural propagation method to carry out seeding and seedling raising on producing at present, but phenotype differ because the diversity of seedling genetic material causes after afforestation, growing, and is difficult to reach the target of colony's high yield and high quality.Adopt the twig cottage of cyclocarya paliurus propagation technique can cultivate a large amount of choiceness nursery stocks, realize extensive clone afforestation, reach the directive breeding target.
Summary of the invention
Goal of the invention:The present invention utilizes the vegetative propagation technique of plant cuttage, and the blue or green money willow of clip spray carries out cuttage, cultivates the consistent choiceness nursery stock of gene and is used for producing afforestation, can significantly improve yield per unit area.
Technical scheme:For solving the problems of the technologies described above, technical scheme of the present invention is following:
1, the twig cottage of cyclocarya paliurus propagation method comprises the steps:
(1) in mid-March～mid-April, the healthy and strong nursery stock of from the nursery stock of growing directly from seeds, choosing life in 1～2 year cuts and does short sprouting, and cutting dried highly is 20～30cm, and the elite stand of shoot cutting fringe is provided with cultivation;
(2) in June～early August, from adopting the long semi-lignified spray of clip 10～15cm on the fringe elite stand, top keeps 5～6 leaflets, and the branch lower end cut is the angle shape;
(3) slotting fringe lower end 3～4cm dips in and gets indolebutyric acid pasty state root-growing agent;
(4) use during cuttage the small wooden thicker slightly than slotting fringe diameter on the seedbed, to insert an aperture earlier, will insert fringe then and insert in the light matrix, the cuttage degree of depth is 4～5cm, will insert the matrix compacting around the fringe then.And water immediately 1 time permeable, make and insert fringe and matrix is combined closely;
(5) branch after the cuttage being used obscurity is that 50～70% black sunshade net shades, and adopts intermittent spray-on process to carry out spraying and moisturizing to inserting fringe.7 of every mornings add a cover the sunshade net, open in order to slotting fringe absorption dew for 6 at dusk.In first week after the cuttage, the spray intervals time is 5 minutes daytimes, and in 10～15 minutes evenings, spray time is 15～20 seconds.After one week of cuttage, the spray intervals time is adjusted into 10～15 minutes daytimes, and in 15～20 minutes evenings, spray time is 20～25 seconds.After the cuttage 30 days, the spray intervals time is adjusted into 20～30 minutes daytimes, and spray time is 20～25 seconds, stops spray evening.Every at a distance from 1 800～1000 times of 50%wt carbendazim solution of 7～10 days foliage-sprays, whenever at a distance from 1 0.2%wt urea of pouring in 10～12 days and 0.2%wt potassium dihydrogen phosphate.
The concentration of the indolebutyric acid pasty state root-growing agent in the step (3) is 500～800mg/L; Compound method is: take by weighing the indolebutyric acid powder with the dissolving of a small amount of alcohol after; Be mixed with 500～800mg/L solution with the distilled water constant volume; Add talcum powder furnishing pasty state then, its viscosity is dipped in not drip after getting and is advisable to insert the fringe lower end.
Light matrix components in the step (4) is the pine bark and the wood sawdust mixture of abundant carbonization; Its part by weight is 5:1, adopts the nonwoven can, is cut into the 15cm section and puts in the frame of plastic of long 50cm * wide 50cm * dark 15cm; Irrigate with the 0.5%wt liquor potassic permanganate, get final product cuttage after 24 hours.
Beneficial effect:Twig cottage of cyclocarya paliurus propagation method provided by the invention, its practicality simple to operate is applicable to extensive cuttage; Seedling raise period is short, and cuttage is after 60 days, and the cuttage root-taking rate reaches more than 80%; And seedling can effectively keep the good genetic character of elite stand, has guaranteed the unanimity of new plant with the elite stand fine quality.
