Abstract

The present invention provides a T-shaped bud grafting method for graftage of wintersweet, and is mainly characterized by that said method includes the following steps: cutting T-shaped slit on the stock of wintersweet, then downwards inserting the hadromestome-less scion piece whose one layer only possesses one bud body into the slit, and retaining tight contact of upper edge of scion piece and upper edge of said slit, binding the connective portion of them with plastic strip, and exposing the leaf stalk and bud body. Said invented wintersweet grafting method is simple, easy to implement and high survival rate.

Description

A kind of method for grafting wintersweet

The present invention relates to the propagation method of a kind of flowers, special relevant with the propagation method of wintersweet.

Wintersweet is for Calycanthaceae wintersweet belongs to, chrysanthemum is opened in the Winter-Spring, and ornamental value is high, is special product of China.Tradition wintersweet propagation method has division propagation, high pressure breeding, cottage propagation, propagation by grafiting.Division propagation and high pressure breeding are only applicable to family; The cottage propagation facility is strict, and management difficulty is big, and specialty unit in gardens just can use.Grafting is to produce propagation method the most commonly used at present.Say that the breeding of wintersweet is based on cut-grafting among Chen Junyu, Liu Shi Hanzhu " landscape flower ".Cut-grafting is carried out time in the about week in spring when the wintersweet leaf bud expands to the wheat size.Earlier stock is cut off apart from ground 5CM place, scabbled clip, hinder face 1/3 place by clip and split a vertical incision, be about 3--4CM, stock cuts the back cutter is cut in the scion front, and it is similar that length and stock are split mouth, cuts the little tangent plane of a horse ear shape behind again, be about 1CM, scion stays 2--3 that bud is cut off, and big bevel is inserted inwards split mouth, on one side stock is alignd with the cambium of scion, with the plastic strip wrapping, cover wet soil then.When treating that scion survives rudiment, in time take blocked up earthing off, remove anvil tiller bud, thereafter earthing again.The 279th page of " practicality grow flower technical manual " that China Forest publishing house in 1994 publishes points out that the grafting of wintersweet has cut-grafting, is abutted against etc.147 pages of stripped methods of being abutted against of having introduced up-to-date employing again of first wintersweet monograph of China " Chinese wintersweet " of Henan science tech publishing house publication in 1993.It require scion length with 2-3 to bud, thick 0.5--0.7CM is advisable, upper cut is level and smooth, lower cut is the inclined-plane, the inclined-plane dorsal part reaches between xylem and the cambium deeply with the scraper cortex of pruning, and does not hinder xylem.Above-mentioned these grafting methods are cut, cut, connection technology requirement height, and tangent plane must be level and smooth, have only consummate gardens professional just can accomplish, and are time-consuming, and often hundreds of young plant wood needs 3-4 grafting to finish, and survival rate is low.

The object of the present invention is to provide a kind of simple to operationly, survive secure method for grafting wintersweet.

Below method for grafting wintersweet of the present invention is described in detail.

The method step of grafting wintersweet propagation technique of the present invention is as follows:

1. the preparation of grafting

A. stock.With full stump before the rudiment of annual or perennial wintersweet stock, select the good tiller bud in orientation to stay after the rudiment and decide anvil earlier, remaining gets rid of without exception.

B, scion.Late April, will get the young sprout pinching of doing scion, promote shoot semi-lignified then, allow it the bud of giving birth to and fully break up and reach full ripe bud fully, in time sprout in order to grafting survival in the future.

2. grafting method

A, stock opening.In mid-May, in the 5--10CM scope of ground (or major branch), select northwest at stock earlier to smooth position crosscut one cutter, then perpendicular from bottom to top cutting makes it to become one " T " notched cut.Transverse incision length is no more than half of diameter of stock, and adapts with bud sheet width, and the degree of depth gets final product to cut off cortex.Be advisable to load the bud sheet for perpendicular mouthful long.

B, produce the bud sheet.Cut the former branch that is equipped with fringe with the hand secateurs earlier and do scion.Fringe is with using with cutting, and got the same day, and the same day, usefulness can not be put for a long time.When cutting with budding knife earlier under the bud 1.5CM cut into xylem and upwards be whittled into rip cutting above bud 0.3--0.5CM place, then above bud 0.3CM place crosscut cortex to longitudinal incision, pinch to budder with hand then and one break off with the fingers and thumb and promptly take off the bud sheet, make the whole band of bud vascular bundle on the bud sheet.Bud sheet size is cut into the xylem degree of depth with cutter and is directly proportional, and can determine the bud sheet size of getting according to the stock thickness like this.

C, grafting.Choose out gently stock is suitable for reading earlier with the bud grafting handle of a knife, the bud sheet is slowly inserted from top to bottom, keep bud sheet upper limb and otch top to connect airtight.With the wide plastic strip of 0.5--1CM interface is wrapped up then.From the top of bud, progressively downward winding plastic bar exposes the petiole of bud sheet and sprout during wrapping.

Also can put in order with point of a knife during the stock opening, push cortex aside with point of a knife then, during grafting the bud sheet smoothly be inserted, advance slowly, the stock cortex is broken with the propelling of buddering, reach bud sheet upper limb and transverse incision and connect airtight in transverse incision central authorities, and then wrapping.

3. connect post processing.Cut off apart from the 20CM place of buddering or fracture with being about to the stock tip after the grafting.And the full deduction of axillalry bud on the stock fallen, axillalry bud is detained while sprouting gone.Racemosus stock grafting is successively still handled like this.New coppice spout is with seeing with smearing on the stock, to guarantee to have the rudiment of buddering of enough nutrition supplies.

Can survive in 15 days after the general grafting, budder in 25 days and to sprout.Sprout the back first quarter moon can long 15cm about, in time take off binder this moment.It is long to reach 30-40cm after January, and one and a half months is early July, can reach the 60cm height, and this phase begins pinching until late July, and capping is expired the strain bud and hung branch so then, and promptly bloom next year in good time.

Grafting method provided by the invention be a sprout of one deck band wintersweet then rawhide bits carry out grafting, be not with xylem, and do not cut smooth flat, operation is simple, contractibility is big, as long as the bud sheet is of moderate size, operation work efficiency height is about each skilled gardens technology grafting on work day 1000 strain.Survive securely, survival rate can reach more than 95%.Economize on the fringe bud, only need a monomer bud, other method then will be used 4-6 bud at least.Become the seedling time fast, the wintersweet of time-division in the Beginning of summer grafting sprouted June 1, buddered June 16 and took out living 10cm length, and June 28, young sprout reached 30cm length, and it is long promptly to reach 60cm on July 8.Grafting time is long, can reach first quarter moon.
