Abstract
The present invention discloses a method of increasing the seedling grafting survival rate. The method comprises the following steps of stock cultivation, scion cultivation, nutrient solution preparation and grafting. According to the grafting method, the seedling grafting survival rate can be largely increased, and the seedling survival rate is ensured to be more than 95%. Through cultivating the stock in advance, overall quality, disease resistance and survival performance of grafting carriers can be effectively improved, an excellent carrier environment is provided for scions to be grafted later, and final grafting failure caused by scion death due to low quality of the stock is prevented. Through cutting the top of the periphery of a crown of a seed tree, strong and healthy first-stage and second-stage lateral branch top shoots exposed to the sun are the scions, leaves and tender shoots are removed from the cut branches, health of the scions can be ensured, and the step is very important to successful survival of the scions.
Description
Technical field
The present invention relates to seedling grafting field, a kind of side improving seedling grafting survival rate
Method.
Background technology
In present seedling grafting, often because artificial unreasonable plantation causes transplanted seedling tree
Survival rate relatively low, both wasted the time, the most significantly wasted land utilization ratio, the most significantly
Improve the grafting cost of nursery stock, therefore, present grafting market survives in the urgent need to a kind of height
The seedling grafting method of rate.
Summary of the invention
The technical problem that present invention mainly solves is that providing a kind of improves seedling grafting survival rate
Method.
The present invention solves that the technical scheme that above-mentioned technical problem uses is:
A kind of method improving seedling grafting survival rate, said method comprising the steps of:
A. stock is cultivated: after being elected to be the seed maturity of stock, pluck in time, loose ventilative
Sandy loam seedbed on, cover one layer of thin loess, to be poured permeable after, cover PET film up；
March in next year comes up, and throws off PET film, within 2-3 days, spray a nitre under dark environment
Acid ammonium, then after staying seedbed 1-1.5 month, move it in time nursery, mountain region or draining is good,
In the nursery that soil is deep, mugineic acid fertilizer in nursery；Then cut off seedling main root, stay
3/4, carrying out waters determines root operation；The watering, fertilizing as height of seedling 20-25cm, nitre selected by fertilizer
Acid ammonium, pours water after fertilising saturated to soil water amount immediately；
B. scion cultivated: with the outer upper part of scion-seed tree tree crown, on the sunny side, the one of sturdy health
Level, two grades of side shoot top tips are scion, and the branch cut removes blade and the tender tip, retain 1cm
Long petiole, breaks into bundle by the scion branch cut, and is uprightly put at leeward cool place, lower half
Demultiplexing damp sand is trained, and top water spray is anti-dry；
C. prepare nutritional solution, by weight component to take: ammonium sulfate 50-65 part, MAP
18-22 part, calcium superphosphate 30-35 part, potassium sulfate 12-30 part, sulfur 5-15 part, sulfur
The ferrous 5-7 part of acid, Malathion 0.01-0.015 part, nitrogen (N) 15-22 part, five oxidations two
(P2O5) 12-15 part, potassium oxide (K2O) 14-18 part, carbamide 25-30 part, potassium dihydrogen phosphate
39-45 part, magnesium sulfate 5-7 part, dilute after mixing, obtain nutritional solution；
D. grafting: after stock cultivation, the Second Year 3-4 month is in nursery grafting；The process of stock: will
Step a gained stock truncation, clips the tip under the principle retaining stock base portion 3-5 bar side shoot,
It is close to trunk xylem outer longitudinally the deepest the stock otch, length 3-4cm with grafting blade；
Cut scion: the gained scion of step b cut so that it is grafting mouth is positioned at the autumn and slightly goes up；Carry out grafting:
The cambium layer that the cambium layer of the scion otch either side after cutting is corresponding with stock otch docks, it
Twine with grafting thin film bandage afterwards and tie up；
E. by the stock after the grafting of step c, above stock, set up sunshade net, keep ground, garden wet
Profit and not hydrops, cut the stock side shoot that growth is too fast, after grafting 1.5-2 month, and releasing is transferred
Connecing bandage, the most monthly spray concentration is fertilizer aqueous solution 1-2 time of 1-2%, and nursery stock is trained
Educate to grafting and month next year 3-4 can go out garden.
Further, in described step a, before grafting, the branch of sprouting of anvil Seedling bottom is wiped out by base portion,
And spray 1 antibacterial and insecticide.
The invention have the benefit that
The engrafting method of the present invention can be greatly improved the survival rate of seedling grafting, it is ensured that nursery stock
Survival rate is more than 95%.
By in advance cultivation to stock, can effectively promote grafting carrier total quality and
Disease resistance and Viability, provides an excellent carrier environment to the scion wanting grafting afterwards, anti-
Only because the low quality of stock causes the death of scion to cause last grafting failure.
By the outer upper part of scion-seed tree tree crown, on the sunny side, the one-level of sturdy health, two grades of side shoots
The top tip is scion, and the branch cut removes blade and the tender tip, it is ensured that the health of scion,
It is that scion can successfully survive a very important ring.
By the engrafting method of the present invention, scion and anvil in grafting procedures can be prevented effectively from
The probability of wood interface bacteria infection, then by the sprinkling of antibacterial, grafting can be greatly promoted
Success rate.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further elaborated.
A kind of method improving seedling grafting survival rate, method comprises the following steps:
