CN105145123A - Single bud cleft grafting method of walnut seedlings - Google Patents

Abstract

The invention discloses a single bud cleft grafting method of walnut seedlings. The method comprises the following steps that a 1-4-year-old stock which has a diameter of 1cm or more is selected, and sheared at the position 10cm over the ground; the middle part of the stock is vertically split for about 5cm by a knife; a pair of symmetric inclined planes are cut on two sides of the grafted scion, wherein the length of the inclined planes is 5-6cm, and the thickness at the lower end of the scion is about 0.2cm; then, the end, with the cut planes, of the grafted scion is quickly inserted into the cut of the stock, and the cambium of the scion and the cambium of the stock are aligned; and finally, a polyethylene film which is 3-4cm wide is used for fastening the grafted position from bottom to top in a manner of being loose firstly and tight afterward, so that the grafted scion is tightly enclosed. The method has the beneficial effect that the cleft grafted seedling is tightly connected and cannot be broken by wind after surviving, the grafted position is well healed, and the grafting survival rate is high.

Description

A kind of Juglans simple bud cleft grafting method

Technical field

The invention belongs to planting technology field, relate to a kind of Juglans simple bud cleft grafting method.

Background technology

The grafting gimmick of current Juglans is a lot, as scion grafting and bud grafting two kinds.Scion grafting can be divided into again scion grafting in spring green scion grafting in summer and micro-grafting 3 kinds.Grafting gimmick is a lot, the having cortex grafting, insert skin whip graft, two whip graft, cleft grafting, cut knot, dig bone and connect of main application at present, but current low for the survival rate of Juglans simple bud grafting.

Summary of the invention

The object of the present invention is to provide a kind of Juglans simple bud cleft grafting method, solve problem low for the survival rate of Juglans simple bud grafting at present.

The technical solution adopted in the present invention is carried out according to following steps:

Step 1: the stock selecting 1 ~ 4 year raw diameter more than 1 centimetre, on ground, 10 centimeters cut off stock;

Step 2: with cutter stock intermediate vertical split into, deeply about 5 centimetres;

Step 3: inclined-plane scion both sides respectively being cut a pair symmetry, long 5 ~ 6 centimetres, thick 0.2 cm in lower end;

Step 4: then rapid in scion bevel insertion rootstock opening-cleaving, makes both sides form layer alignment;

Step 5: then use 3 ~ 4 centimetres of wide polyethylene films from bottom to top, first tight after pine, grafting part is tightened, scion Bao Yan.

The invention has the beneficial effects as follows that cleft grafting nursery stock interface is firm, not easily rolled over by wind after surviving, grafting part heals, and graft survival rate is high.

Embodiment

Below in conjunction with embodiment, the present invention is described in detail.

The inventive method is as follows:

Step 1: the stock selecting 1 ~ 4 year raw diameter more than 1 centimetre, on ground, 10 centimeters cut off stock; Stock rudiment all can cleft grafting to leaf stretching period, and grafting time is longer.Also grafting of tender branch can be carried out by this method.

Step 2: with cutter stock intermediate vertical split into, deeply about 5 centimetres;

Step 3: inclined-plane scion both sides respectively being cut a pair symmetry, long 5 ~ 6 centimetres, thick 0.2 cm in lower end;

Step 4: to be inserted in rootstock opening-cleaving by scion bevel then rapidly, makes both sides form layer alignment, accomplishes " upper White Dew (0.5 centimetre), under pedal sky "; All align in stock and scion phloem both sides, there is certain thickness scion lower end, avoid connecing soaking grafting part because of bleeding afterwards, and are lowered into motility rate.

Step 5: then use 3 ~ 4 centimetres of wide polyethylene films from bottom to top, first tight after pine, grafting part is tightened, scion Bao Yan.Note, film crosses individual layer when buddering, bursting film after sprouting in order to bud.

The cleft grafting of Juglans and other fruit tree are distinguished and are, require stock and scion thickness basically identical, scion retain 1 ~ 2 bud.

The advantage of Juglans simple bud cleft grafting method of the present invention is: cleft grafting nursery stock interface is firm, and not easily rolled over by wind after surviving, grafting part heals, and graft survival rate is high.

The above is only to better embodiment of the present invention, not any pro forma restriction is done to the present invention, every any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.

Claims (1)

1. a Juglans simple bud cleft grafting method, is characterized in that carrying out according to following steps:

Step 1: the stock selecting 1 ~ 4 year raw diameter more than 1 centimetre, on ground, 10 centimeters cut off stock;

Step 2: with cutter stock intermediate vertical split into, deeply about 5 centimetres;

Step 3: inclined-plane scion both sides respectively being cut a pair symmetry, long 5 ~ 6 centimetres, thick 0.2 cm in lower end;

Step 4: then rapid in scion bevel insertion rootstock opening-cleaving, makes both sides form layer alignment;

Step 5: then use 3 ~ 4 centimetres of wide polyethylene films from bottom to top, first tight after pine, grafting part is tightened, scion Bao Yan.
