The engrafting method of blue berry
Technical field
The present invention relates to blue berry field of planting, be specifically related to the engrafting method of a kind of blue berry.
Background technology
Blue berry, fruit is blueness, and there is one layer of white fruit powder on surface, and sarcocarp is fine and smooth, and taste is sour-sweet, and has the fragrance of uniqueness
Abnormal smells from the patient.Blue berry, rich in various trace elements and multivitamin, has the various health care functions such as enhancing immunity, slow down aging.Remove
Outside eating raw, blue berry is also extensively used for the industry such as food and pharmacy.Remarkable in economical benefits, domestic and abroad market prospect is the widest
Wealthy.Blueberry cultivation starts from the U.S. in 20 beginnings of the century, and China's blueberry cultivation history is shorter, is currently under the fast-developing phase.
China starts from upper world eighties to the research of blue berry, has carried out the work of blue berry introducing and planting, to blueberry cultivation skill
Art, soil improvement work have done numerous studies, and Chinese Academy of Sciences Nanjing plant institute introduces a fine variety blue berry from the U.S. and carries out cultivation research, and
Filter out the improved seeds of applicable south China regional culture.Existing blue berry, in planting process, needs to change soil
Good, the acid-base value adjusting soil enables the plantation needs meeting blue berry, and soil improvement is the heaviest in the cultivation work of blue berry
The link wanted, existing blue berry in the course of cultivation, often has and causes blue berry Seedling to produce situations such as burning root with improper fertilization, and
And due to the existing inadequate precise specifications of blueberry cultivation method, cause blue berry during field planting, often take root for becoming slowly
Motility rate is low, and cultivation period is long, and the Yield compari@causing blue berry is low, reduces economic benefit, seriously hinders the sustainable of blue berry
Development, it is impossible to meet the needs of plantation.
Chinese patent CN 104067864 A discloses a kind of mode using bud grafting with Vaccinium ashei for stock grafting south
The method of high clump blue berry, the method survival rate is high, and tree vigo(u)r is relatively strong, high to edaphic condition adaptability, the resistance to blue berry root rot
Relatively strong, but limited by grafting method, its result cycle is long, yielding poorly of single result, makes the output value of blue berry be restricted.
Summary of the invention
It is an object of the invention to provide the engrafting method of a kind of blue berry, the survival rate of grafting can be significantly improved, connect simultaneously
Fringe growth is fast, and the result cycle is short, it is easy to improve the yield of result.
For achieving the above object, present invention employs techniques below scheme:
The engrafting method of a kind of blue berry, comprises the following steps:
1) scion selects
Select high clump blue berry plant enter hibernation branch without bud as scion, scion a length of 10~15cm, scion
A diameter of 5~10mm;Cut a tapered ramp in the lower end of scion, the old cortex at the back side, inclined-plane is pruned gently, exposes green
The tender skin of color, the length of tender skin keeps consistent with the length on inclined-plane;
2) stock is chosen and is processed
The raw branch of Root-stock selection Vaccinium ashei base, at the smooth straight local selection graft position of stock, at graft position horizontal stroke
Cut once, rip cutting twice, form a bar shaped cortex, the width of bar shaped cortex is not less than the diameter of scion, and at bar shaped skin
Layer upper end pries open some gaps gently;
3) scion process before grafting
First scion clear water is soaked 12h, soaks 12h the most in the medium, culture medium be WPM+ sucrose+agar+swash
Element, wherein sucrose concentration is 2~3%, and agar concentration is 0.60~0.65%, and hormone is 6-BA (the 6-benzyl of 0.5~5.0mg/L
Amidopurin), 0.01~the De Kalin alkali of 0.05mg/L and the NAA (naphthalene acetic acid) of 0.05~0.25mg/L;Finally prune scion,
Keep bud number at 3~4;
4) grafting processes
Grafting time is selected in carrying out for 3~5 days before branch bud in early spring is sprouted;Scion lower end is inserted on bar shaped cortex gently
In the gap of end, making inclined-plane face toward stock xylem, green tender skin faces toward bar shaped cortex, and insertion depth keeps one with chamfer length
Cause;
5) budder and survive management
Axillalry bud on stock is all broken, keeps the absolute advantages of scion, promote scion fast-growth;Carry out suitable simultaneously
Time pinching, fertilizing, watering, deinsectization diseases prevention management.
The engrafting method of the blue berry of the present invention, its beneficial effect shows:
The raw branch of Root-stock selection Vaccinium ashei base, at the smooth straight local selection graft position of stock, at graft position horizontal stroke
Cut once, rip cutting twice, form a bar shaped cortex, the width of bar shaped cortex is not less than the diameter of scion, and at bar shaped skin
Layer upper end pries open some gaps gently.Inside adhesion due to green tender skin Yu bar shaped cortex, it is easy to producing callus will
Both connect, and the stock bark on bar shaped cortex both sides does not peel off xylem, it is easy to produce more callus oblique with scion
The more callus that face the right and left produces is connected, and the most this engrafting method is easier to survive than additive method, survives
Rate is typically more than 98%, and the result cycle can substantially shorten, and improves the yield of result simultaneously.
