Abstract
The invention discloses an open ground hard branch cuttage cultivating method for cornus alba in the northwest arid region to solve the problem that according to an existing hard branch cuttage method for cultivating the cornus alba, the cuttage survival rate is very low. According to the method, hard branch cuttage seedling cultivating is carried out on the open ground, an open ground level bed is covered with a mulching film so that cuttage cultivating can be carried out, and thin branches formed after one-year growing serve as cuttings and are cut to be stored in sand; before cuttage, the thin branches are processed through ABT6 rooting powder, irrigation is carried out immediately after cuttage, and secondary irrigation is carried out 30 to 35 days later; rooting is carried out 30 to 45 days after cuttage, water and fertilizers are controlled from the middle of July to September, and 1.5-2.0 cm adventitious buds are reserved on the roots of the seedlings in spring the next year. According to several-year practice survey, the survival rate is controlled to range from 96.8 percent to 98.3 percent. By means of the method, the cornus alba seedlings can reach the standard for moving nursery seedlings out of a garden after being cultivated for two years, and the cornus alba seedlings can be moved out of the garden in the third year. By means of the method, a large number of cornus alba seedlings can be cultivated in the northwest arid region, the cultivating materials are easy to obtain, and the seedling cultivating cost is low.
Description
Technical field
The invention belongs to raising technology, relate in particular to a kind of northwest arid area tatarian dogwood open country cuttage mating system.
Background technology
Tatarian dogwood (
cornus alba), having another name called tatarian dogwood, Liang Zimu, Cornus controversa, Cornaceae tatarian dogwood belongs to machaka, does and directly grows thickly, Gao Keda 3m left and right; Spend little yellow-white, be corymbiform cyme; Florescence is five to June, drupe: tiltedly oval, and white or slightly band is blue when ripe, fructescence is in the 8-9 month; Its spring and summer pattern is yellowish-white, and autumn leaves is scarlet, and fruitlet is pure white, and after fallen leaves, limb is red gorgeous as coral, is rare sight stem plant, is also a good material of cutting.In gardens, on many group planting lawn or plantation alternate with aiphyllium, the green and the end setting off each other, brings out the best in each other.Its wide adaptability, introduces Hexi Corridor Region cultivation the nineties in 20th century, and cold-resistant, drought-enduring, resistance to pruning, is comparatively desirable afforestation ornamental tree species, has been widely used in street, community and courtyard greening.
Current tatarian dogwood breed mainly taking greenhouse the cuttage of husky bed or full exposure cutting propagation as main, and in northwest arid area, the majority base of growing seedlings lacks this culture facility, breeds more difficult; Majority grow seedlings family from other places introduce seedling cultivate drop into nursery stock market, nursery stock production cost is high, all the time, numerous researchers, technical staff, nursery stock production person are constantly testing and can carry out the method that tatarian dogwood is bred in this area by rapid, high volume, but according to the open country plastic mulching hardwood cuttage method of other seeds of this area, the cuttage survival rate of tatarian dogwood is only 5～20% left and right, even falls flat.
Summary of the invention
The object of this invention is to provide a kind of northwest arid area tatarian dogwood open country cuttage mating system, breed tatarian dogwood according to existing hardwood cuttage method and cause the problem that cuttage survival rate is extremely low to solve.
Technical solution of the present invention is as follows: a kind of northwest arid area tatarian dogwood open country cuttage mating system, carry out hardwood cutting and seedling raising at open country, open country level bed covering with plastic film cutting propagation, the annual growing way of cuttings clip medium compared with withe bar and carry out sand hide, the Controlled irrigation time after cuttage, specifically comprise the steps: A, the preparation of cuttings and processing: in the 3-4 month in early spring, after tatarian dogwood branch is restrained oneself winter low temperature dormancy, branch physiological activity starts recovery, but when sprout does not sprout, now in branch, the carbohydrate of accumulation is more, and body bud is full, grow perfect, it is the golden hour that hard stem cutting fringe intercepts.Clip tatarian dogwood branch will be taking the annotinous branch between diameter 0.5～0.7cm as main, because the golden mean of the Confucian school easily produces adventive root compared with withe bar than sturdy person, cuttings is stayed 3 bud joints, length is 15～18cm, cut as flat mouth apart from terminal bud 1cm place upper end, and cut as angle in least significant end bud opposite lower end, angle 30-45 degree angle, every 100 by its bud towards consistent binding, be first embedded in layering storage in the wet sand of shady spot;
B, ground, garden are prepared: nursery selects physical features smooth, and loosing soil is organic abundant, the plot that irrigation conditions is good; Before cuttage, use sufficient base fertilizer, and with copper acetate wetting powder 1000-1500g/667m
2mix fine earth and spread fertilizer over the fields the sterilization that carries out disinfection, then plough deeply to polish and make level bed, level bed covers the wide black mulch film of 70cm, is beneficial to increase gentle weeding, line space 30～40cm;
C, cuttage: when cuttage, with the punching of seedling cone, can not make like this cuttings lower end decortication or residual with mulch film, cause survival rate low.Cuttage seeding row spacing 20cm × 30cm, cuttings 65～70 degree angle oblique cuttings, the lower slotting degree of depth 10～12cm, crosses shallow mistake and is deeply difficult for taking root, and after inserting, pour water immediately in ground, garden;
D, slotting rear management: after cuttage, 30～35d fills with and pours water for the second time, and too early or overirrigation all can cause ground temperature decline, and cuttings base portion cortex turns black and rots, and this is the key that ensures cutting survival.After pouring water, inter-row cultivation loosens the soil, and in order to soil moisture conservation and lifting ground temperature, ensures surviving of cuttings; After Survival rate of nursery stock, pour water according to soil moisture content and fertilising in good time, between mid-July-September, will control water control fertilizer, promote nursery stock branch sturdy substantial, be beneficial to survive the winter; Second Year base portion in spring stays 1.5～2.0cm stump, promotes nursery stock branch; Within the 3rd year, can go out garden.
Preferably, in the preparation of steps A cuttings, before cuttage tatarian dogwood branch, process (ABT6 root-inducing powder is purchased from Beijing middle forest Jia Lin Science and Technology Ltd. and produces) with ABT6 root-inducing powder, before cuttage, taking-up is processed with ABT6 root-inducing powder 100ppm, cuttings lower end is placed in the dark liquid for 5cm to soak time 2-3h.
In northwest arid area, with the inventive method cuttage tatarian dogwood, through Practice Survey for many years, survival rate is between 96.8%～98.3%.The present invention breeds tatarian dogwood nursery stock and within 2 years, reaches garden specification, within the 3rd year, can go out garden.This method has realized breeds tatarian dogwood nursery stock in a large number in northwest arid area, and breeds material and easily obtain, and seedling cost is lower.
