Abstract

A method for planting Caryacathayensis relates to the technical field of fruit seedling grafting. The method includes the following steps of: selecting an oak as a stock, cutting a part of the stock, 10 cm above the land, at an angle, to form an acute angle-shaped cut, and cutting open the edge of the acute angle-shaped cut downward, wherein the cutting length is 3cm and the cutting width depends on a cion; selecting a Caryacathayensis fruit branch as the cion, and performing one cut at two sides of the cion to form a V-shaped cion; directly inserting the cion into the cut of the stock, covering the joint position between the stock and the cion with a thin film, and coating the film with yellow mud water after the joint position is tightly covered; observing the Caryacathayensis once every 3 to 4 days after grafting, removing oak new buds, and cutting out the stock part being 1 cm above the cion, in the fifteenth day after surviving. The method has the benefit effects that: good grafted seedlings can grow up through two-year cultivation, and the good grafted seedlings are healthy and strong, and have full buds; the survival rate of grafting is improved; and dwarf trees can be obtained, and the height of the trees can generally be controlled to be within 5 meters, so that dangers during harvesting of the Caryacathayensis can be reduced, and the harvesting efficiency of the Caryacathayensis can be improved.

Description

A kind of hickory grafting method

Technical field

The present invention relates to fruit seedling graft technology field, particularly relate to a kind of hickory grafting method.

Background technology

Cathay hickory, belonging to Juglandaceae, is perennial arbor oil plant and senior commerical tree species.The fat composition of its dry fruit food product is based on unsaturated fatty acid, has the health care of the cholesterol reduced in blood, softening blood vessel wall.Along with the raising of people's material and cultural life, at home and abroad supply falls short of demand on market for walnut kernel and walnut oil.At present, the place that cathay hickory primary growth is severe in mountain area etc., is plucked by artificial method, and because hickory is general higher, event of often hurting sb.'s feelings, causes that the harvesting productivity ratio of cathay hickory is low and working environment is dangerous.

Summary of the invention

The present invention seeks to solve the large problem of hickory height.

The present invention is achieved through the following technical solutions:

A kind of hickory grafting method, comprises the steps:

(1) stock process: select without damage by disease and insect and the Oak Tree of more than the 1 year age of tree as stock, cut sth. askew at stock acrial part 10cm place, form " ∠ " type otch, cut downwards at the edge of " ∠ " type otch, length is 3cm, and width is depending on the rugosity of scion;

(2) scion process: the result cathay hickory elite stand selecting the age of tree more than 20 years, shears the annual fruit branch of tree crown top peripheral without damage by disease and insect as scion, a cutter is respectively cut in scion both sides, forms " V " shape;

(3) grafting: incision scion vertically being inserted stock, with the interface of film wrapped stock and scion, coats yellow mud water after wrapping closely;

(4) leaf-cutting: observe once, extract the Oak Tree sprouting grown, wipe out the stock part at 1cm place above scion after grafting survival for 15 days for after grafting every 3-4 days.

The angle of described " ∠ " type is 30 degree of-60 degree.

The invention has the beneficial effects as follows:

(1) utilize well developed root system, sprout the strong Oak Tree of an ability as stock, with the age of tree cathay hickory of more than 20 years growth branch for scion, cultivated through 2 years, the improved seeds grafting that stalwartness, bud are full can be grown into;

(2) above technical scheme is adopted, by the scion grafting that comprises adult branch physiological ripening feature on the strong Oak Tree stock of affinity, improve graft survival rate, and tree body realizes downgrading, generally highly can be controlled within 5 meters, decrease danger when cathay hickory is plucked, improve cathay hickory picking efficiency.

Embodiment

Below in conjunction with specific embodiment, the present invention will be further described.

First growth selection better, without damage by disease and insect and the Oak Tree of more than the 1 year age of tree is cooked stock, cut sth. askew at stock acrial part 10cm place, form ' ∠ ' type otch of 30 degree, cut downwards at the edge of ' ∠ ' type otch, length is 3cm, and width is depending on the rugosity of scion; Then the result elite stand of the age of tree more than 20 years of growth selection stalwartness in the improved seeds of cathay hickory, its tree crown top peripheral select sturdy, smooth, tooth spore is full, without the annual fruit branch of damage by disease and insect, (graft survival rate when scion 5cm is long is the highest as scion again it to be cut into 5cm length, long or too short scion all can affect survival rate), every section of cathay hickory fruit branch there is 1-2 gemma, a cutter is respectively cut in scion both sides, forms ' V ' shape; Scion is vertically inserted the incision of stock, carry out parcel and tighten, coat after parcel with yellow mud water again with wide 2cm through the film of sterilization, play interception, grafting procedures carries out the best at the cloudy day, and cathay hickory fruit branch now adopts that to be now connected into motility rate higher; Within after grafting every 3-4 days, observe once, extract the Oak Tree sprouting grown, after grafting survival, within 15 days, wipe out the stock part at 1cm place above scion.

More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification is only preference of the present invention; be not used for limiting the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.

Claims (2)

1. a hickory grafting method, is characterized in that comprising the steps:
