Description

A kind of Nursery Stock cultivating method
Technical field
The present invention relates to Nursery Stock culture technique field, especially relate to a kind of method of utilizing tree trunk, grafting root graft to cultivate Nursery Stock.
Background technology
At present, along with the continuous progress of society, urbanization process is advanced continuous acceleration, and people's material and culture level is also improving constantly, various park and garden construction in Process of Urbanization Construction have obtained popular favor, are various ornamental plant trees and park and garden construction mainly relies on.The various trees growth needs decades of occurring in nature, even the centuries could form its distinctive sight and value thereof.The existing plant tree with ornamental value is very few, rare incomparable, and price is extremely expensive.Moreover these rare ornamental plants trees are to be all grown in remote region, the place that not people need most.In order to solve reality or potential environmental problem, coordinate the relation of people and environment, ensure the sustainable development of economic society, environmental protection all, in the policy of taking to conform to national conditions, is carried forward vigorously in countries in the world, for example: forbid excavating wild ornamental trees and shrubs.Because the growth cycle of trees is very long, especially there is the large tree of ornamental value, can not meet society now far away and, to the trees demand in park and garden construction, have a strong impact on the paces of accelerated development Process of Urbanization Construction.In order to carry out Environment Protection Policy and to obtain the resource of enriching ornamental plants tree; society has been carried out a large amount of further investigations to the woody plant of occurring in nature; for example adopt graft technology to promote the moulding of each Plants tree Fast Growth, these technology have had relevant report and announcement on publication.
CN101066034 discloses the method for combining small trees into big tree, selects equal monomer trees at least 2 strains that belong to together, and the large-tree-shaped shape that is designed to want is planted to survive and respectively monomer whose trees carried out to shaping afterwards, except branch, the worm branch of preventing or cure a disease; The epidermis that monomer trees mobile jib is abutted against to position is again removed, until layer of wood comes out, then by the formation layer between monomer trees near docking, nail is worn and is abutted against after the trunk of two, position the bending of nail other end, clamping, and making trees be abutted against position can not become flexible, sterilize again, be abutted against position with diaphragm seal again, through 3 to 5 years conventional cultivations, make to obtain the large tree after integration.The method feasibility is strong, and easy operating can make tens or upper a century large tree that could naturally grow up to, can be rapid-result within the time of 3 to 5 years, be widely used in urban landscaping and ecological environmental protection.
At present, in the cultivation of Nursery Stock, still main employing transplanted large-scale trees, the technology of combining small trees into big tree, in the time cultivating large tree, still need the time of growing, for arbor class Nursery Stock, the tree-like demand that is difficult to meet urban landscaping cultivating.
Summary of the invention
In order to overcome the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of Nursery Stock cultivating method, can nurture fast tall and big Nursery Stock.
In order to solve the problems of the technologies described above, Nursery Stock cultivating method provided by the invention, comprises the following steps:
1) grafting root sapling is cultivated and prepares: the grafting root sapling that nurtures trunk diameter 1~1.5cm;
2) choose stock trunk: described stock trunk and grafting root sapling are equal belonging to together, by the trunk section of being cut into, by the flat two ends saw stock trunk of doing;
3) grafting tree root: grafting time is selected the trees current growth phase is longer than 6 months, first offer long mouthful of 2 above longitudinally wedge shapes in the stock trunk lower end of the section of being cut into, longitudinally the long mouth of wedge shape exposes xylem, the long mouthful degree of depth of wedge shape is to be grafted with 52%~60% of grafting root sapling tree-walk, longitudinally the long mouthful external width of wedge shape is to be grafted with 65%~73% of grafting root sapling tree-walk, take grafting root sapling, retain the root system of grafting root sapling, grafting root sapling is excised near trunk more than root 30~50cm and tree crown, according to stock trunk opening length and the degree of depth, by the skin with the grafting root sapling to be grafted part of pruning, position after peeling is whittled into the shape matching with the long mouth of described wedge shape, and expose xylem, peel and be partially submerged in the long mouth of the longitudinal wedge shape of stock trunk with grafting root sapling to be grafted, the xylem of grafting root sapling and stock trunk opening surface is coincide, make the phloem of grafting root sapling and stock trunk opening surface also coincide simultaneously, prick and tie up with grafting membrane, and reinforce fixing,
4) be coated with last layer wound plastics at stock trunk two ends and grafting place, below stock trunk top 20cm, position is wound around layer protecting film;
5) by after upper step process the stock trunk of grafting tree root plant in soil, stock trunk is supported fixing, build cool canopy, carry out daily cultivation management;
6) the de-preservation film after half a year of planting, removes cool canopy, carries out daily cultivation management.
Further, Nursery Stock cultivating method provided by the invention, cultivates in grafting root sapling process, by the following position of sapling trunk 50cm bending moulding, in grafting process, adopts bending section to make described grafting root sapling and stock trunk be incline direction grafting.
Further, Nursery Stock cultivating method provided by the invention, described grafting time is chosen in for 2~April.
Further, Nursery Stock cultivating method provided by the invention, when the stock trunk of grafting tree root is planted, its lower end is stood at least one timber.
Preferred version, Nursery Stock cultivating method provided by the invention, described stock trunk and grafting root sapling are same seeds.
The beneficial effect that the present invention brings: by grafting tree root on stock trunk, after the stock trunk of grafting tree root is planted and sprouted new buds in soil, can form the large tree that diameter is thicker, a large tree can be cultivated into many large trees, can save large tree resource, reach the object of the large tree of fast culture.
