Water Xun grafting arbor method
Technical field
The present invention relates to the graft seedling growth technology, be specially the method for a kind of water Xun (Cotoneaster multifiorus) grafting on hawthorn (Crataegus pinnatifida) and Siberian crabapple arbors such as (Malus baccata).
Background technology
Water Xun (Cotoneaster multifiorus) is a machaka, and branch is thin, often is bow action, the sprig bronzing, and stipule is linear, comes off; Blade is avette, and the surface does not have hair, spends majority, and about 5-21 becomes loose cyme; Petal is open and flat, white; Fruit is subsphaeroidal, the about 8mm of diameter, redness, the florescence 5-6 month, the fruit phase 8-11 month, like light and anti-slightly the moon, more cold-resistant, extremely drought-resistant and barren, spend numerous fruit gorgeous, autumn, haw was innumerable, did not prolongedly wither, and was good sight flower, saw the fruit tree kind, should plant in by flower garden, park, the residence, on the lawn, but isolated planting, group planting, if match with mountain stone, rather attractive in appearance, be generally sowing or cottage propagation.Since water Xun is used to afforestation, be subjected to the consistent of circle, gardens always and approve, propagation method adopts sowing and cottage propagation always.Because water Xun growth rate is slower, the seedling-wood breeding cost is higher, so use seldom on gardens at present.
Summary of the invention
The object of the present invention is to provide a kind of water Xun grafting arbor method, this method can shorten going out the garden time of water Xun nursery stock, thereby reduces cost, and widely applying in gardens for it provides feasible program.
Technical scheme of the present invention is:
A kind of water Xun grafting arbor method, with becoming the annual hardening branch of boiled water Xun nursery stock as scion, reach the hawthorn of 5~8cm or Siberian crabapple nursery stock as stock with chest stem (liftoff about 1.3 meters), with the scion grafting on hawthorn or Siberian crabapple nursery stock, the grafting interface is selected in 1.5~1.8 meters eminences, and interface heals under field conditions (factors), and its greening shrub type is become greening arbor type after grafting is handled, shorten the outplanting time greatly, and enlarge the range of application in afforestation.
The present invention can be with 7 years, 8 years living nursery stocks of wild hawthorn or 4 years, 5 years living nursery stocks of Siberian crabapple as stock.
Grafting method of the present invention can adopt cleft grafting, insert skin, green whip grafting or bud grafting.
One, cleft grafting
Cleft grafting is generally in 1-April 15 April, and carry out just clear and bright front and back, and best before rudiment, cleft grafting is applicable to thicker stock when resin begins to flow.
Concrete grammar is to get 3~4 buds of scion 10~15 centimeter length bands, is whittled into the two-sided watchman's wooden clapper shape of 2~3 centimeter length in the scion lower end, and will align in the two sides, bevel is level and smooth.Stock is cut off from needed position, the cross section is smooth again, rives with cutter from Section Central then, about 3~4 centimetres of the degree of depth, again stock is inserted in scion rapidly, must have a cambium alignment back to tie up with Polypropylence Sheet, the Polypropylence Sheet of colligation is removed after should remaining into the 2nd year spring.
Two, insert skin
The cortex grafting method is carried out behind skin nursery stock, generally at the beginning of 4 the end of month to 5 month.Be applicable to thick stock, can carry out a high position and change head and racemosus connection.
Cutting of scion got, scion was not generally taked before having rudiment early spring, carry out cryopreservation, the cryopreservation condition is, generally gather in resting stage, temperature guarantees not rudiment of not dehydration of scion about 0~5 ℃, can be in the cellar, in the sand that wets, in the fruit refrigerated room, also available method of sealing with wax carries out that two ends are sealed or whole branches is all sealed and prevented that dehydration from improving survival rate, and the purpose of cryopreservation is:
1, scion resin under resting state also is to flow, its skin zone and xylem this for leaving, it is smooth and smooth to cut the scion section of getting like this, can combine closely with the interface of stock like this, scion does not go out under the leaf state in dormancy, the few dehydration of the nutrition that it consumes is also few, and the healing of this docking port has very big benefit;
2, if dishoarding scion trees about May have been opened up leaf, its fluid loss can be very big, at this moment under the situation of grafting wound for healing, the scion fluid loss is big and the moisture content supply of stock is not gone up, sheltering from heat or light preserves moisture can be lowered into motility rate greatly as not doing, time spent is whittled into scion 2~3 centimetres bevel, be whittled into 1~2 centimetre little bevel overleaf, 2~3 buds are stayed in scion, cut off at the position that needs on stock then, it is smooth to cut the knot face, can make the healing of stock wound reduce evaporation of water like this, reach xylem deeply in the vertical partial application in the smooth place of stock trunk again, length is shorter slightly than scion, then the big bevel of scion is inserted towards stock, note too not deeply, show money or valuables one carries unintentionally the bevel upper end that to stay 0.5~1 centimetre of title to stay white at the place, stay white meeting to make better combination of skin bar of scion and stock, use the Polypropylence Sheet colligation then, the Polypropylence Sheet of colligation is removed after should remaining into the 2nd year spring.Also can connect a plurality of branches aloft simultaneously with the method, evenly distribute, can become a new whole strain after surviving ahead of time, can make beautiful shrub is that the tree bar improves its ornamental value with the arbor.
Three, green whip grafting
Green whip grafting all can carry out when semi-lignified is to lignification to newborn branch at trees exhibition leaf usually, survive as branch too tender just being difficult for, method is identical with cortex grafting, scion will with get with the time can not be long, grafting time stopped to carry out in preceding 1 month to vegetative period after May, if interface can not finish healing and can be lowered into motility rate after surviving the winter too late, its scion should keep 1~2 leaf, should in time entangle in the scion after connecing and on stock, tighten with plastic sack, should strengthen management after its grafting, preventing that Exposure to Sunlight from burning reduces water evaporates and can improve survival rate greatly.
Four, bud grafting
The bud grafting time generally carries out in July-August, is applicable to biennial a large amount of seedlings or straight stem at 1 centimetre of thinner stock, and this method survives simply easily, and can significantly reduce scion with this method under the situation of scion kind bud less source shortage;
Budding method is the horizontal partial application of cutter of 1~2 centimeters above the scion bud, reach xylem deeply, upwards cut a cutter with cutter for about 1~2 centimetre from the below of bud again, bud will be at the center of chipping, taking off the bud sheet then wraps with wet cloth or keeps in the mouth, in stock smooth horizontal partial application in position of 5~8 centimeters apart from ground, reach xylem deeply, be about about 0.6~0.8 centimetre, at the otch of one 1~2 centimetre of the middle rip cutting of transverse incision, T-shaped again, after then stock otch two flaw-pieces being chosen out, the bud sheet is inserted, bud sheet and T word otch are aligned, again the skin on stock both sides is covered, with plastic tape one circle circle wound is wrapped then, attention should keep petiole so that insert the bud sheet, also can survive situation according to the petiole inspection, having come off at a touch with finger as petiole just shows that the bud sheet survives, otherwise does not just survive, can carry out grafting once more, survive the back generally cuts off the top of buddering before 1 year early spring, resin flowed stock.
Advantage of the present invention and beneficial effect are:
1, to have overcome in the prior art in the sowing of water Xun, the cottage propagation growth rate not enough slowly in the present invention, with the grafting of water Xun on hawthorn or Siberian crabapple nursery stock, this method can shorten going out the garden time of water Xun nursery stock, thereby reduce cost, widely applying in gardens for it provides feasible program.
2, grafting of the present invention can be adopted cleft grafting, be inserted skin, green whip grafting or bud grafting, grafting method should be taked corresponding connection according to the different time, different conditions is taked different connections, few as kind of fringe source, can take the method for bud grafting, can carry out to inserting in skin long-time in cleft grafting well as the condition of the sufficient storage of scion, these two kinds of methods are not subjected to the restriction of stock size, and simple, survival rate is higher, survival rate reaches more than 90%.
