[0011]

[Problems to be Solved by the Invention]

[0012] However, in the conventional call-joining, it is not easy to form a hole for inserting a scion having a sufficient depth so as not to penetrate to the opposite side of the rootstock, and the grafting portion is fixed with a clip. Because of the time and labor required, only 150 to 170 lines could be processed per hour.

The hole for inserting the scion is formed by carefully supporting the rootstock with the thumb and forefinger of one hand and holding the tool for punching with one hand so as not to penetrate. , When the rootstock is hard, force is applied to the hand that pushes the tool, and the sharp tip of the tool reaches the fingers supporting the rootstock with excessive force,
I could hurt my finger.

Furthermore, since there is only one adhesion point between the scion forming layer and the root forming layer, the survival rate is about 93 to 95%. In addition, when the rootstock is thin or the hole is shallow, etc. Has
The inserted scion had poor stability and had quality problems such as poor growth and breakage from the grafted part even after survival.

Therefore, there has been a demand for a means capable of performing the work quickly and safely and improving the survival rate and the quality after the survival.

[0016]

[Means for Solving the Problems]

Means for solving the problems of the present invention are as follows.

Firstly, a grafting method in which a through hole is formed in a rootstock into which a spike is inserted, a spike is inserted into the through hole, and a tip portion thereof penetrates through the rootstock to perform a call grafting. is there.

[0019]

[Action]

According to the present invention, the formation layer of the rootstock and the scion is adhered at two positions before and after the insertion side and the tip side of the insertion part of the scion, so that the adhesion area is increased and the grafting result is increased. Have a good effect on.

[0021]

【Example】

An embodiment of the grafting method of the present invention will be described below with reference to the drawings.

Here, FIG. 1 is a schematic view showing an example of the grafting method of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.

In this Example, an example of grafting eggplant seedlings will be described, but the method of the present invention can be carried out on other fruit vegetables.

First, the rootstock 1 is cut diagonally and the cut surface 1 is cut.
A hole 2 for inserting a scion having an inclination angle of about 45 ° is formed so as to penetrate to the opposite side, and the scion 4 with the root 3 still attached to the hole 2 formed in the rootstock 1. Forming an insertion portion 4a for insertion of.

Here, when the hole 2 for inserting a spike is formed so as to penetrate to the opposite side of the base 1, the base 1 is passed by the tip of the blade for punching with the thumb and forefinger. Since the blades are supported with a space between them, the cut-out blade will not hurt your finger.

Then, the insertion portion 4a of the spike 4 is inserted into the hole 2 formed in the rootstock 1 so that the tip portion penetrates about 3 mm, and the epidermis and primary skin layer 4c at the tip portion are inserted into the rootstock 1.
Try to pop out of.

Then, as shown in FIG. 2, the formation layer 4b of the spiker 4 and the formation layer 1b of the rootstock 1 are adhered to each other on the side of the insertion portion 4a where the insertion portion 4a is inserted into the hole 2 and the tip of the insertion portion 4a is formed. It also adheres on the side, and at the front and rear sides on the insertion side of the insertion part 4a of the spike 4 and on the front side, the spike 4 is inserted into the rootstock 1 in a stable state.

[Test Example 1]

With respect to the grafting method according to the present invention described in the above embodiment and the conventional grafting method described in the prior art, the grafting work was actually carried out, and the working speed, the survival rate and the quality after the survival were compared.

Regarding the quality after rooting, it is 2 after grafting.
It was performed by comparing the conditions in the nursery on day 0.

As a result, with respect to the working speed, the conventional method could process only about 150 to 170 lines per hour, while the method of the present invention could process about 190 to 2 per hour.
About 10 lines could be processed, and the speed was improved.

The survival rate is 93 in the conventional method.
.About.95%, whereas in the method of the present invention,
It was about 100%, and an improvement in the survival rate was observed.

Regarding the quality after rooting, the method of the present invention confirmed that the morphological growth was about 5 days earlier than the conventional method, and the quality was improved.

[0035]

[Test Example 2]

In order to compare the living conditions of the grafting method according to the present invention described in the above embodiment and the conventional grafting method described in the prior art, the grafting work was actually carried out, and 20 days after grafting, The following test was conducted.

A 1 cm lower portion of the hole or hole for inserting a spike formed on the cut surface of the rootstock, and after making a horizontal cut from the insert side to the center, a thin plastic barrier plate is provided in the cut. Was inserted, and the subsequent state was observed with the blocking plate blocking the water-passing function of the cambium-inserted formation layer.

As a result, the grafting by the conventional method wilted violently after 5 hours and died 3 days later, while the grafting by the method of the present invention showed no change from the state before cutting after 5 hours. , And continued to grow without dying.

From the above results, in the grafting according to the conventional method, the formation layer is adhered only at one location on the side of the scion insertion, and if the location is blocked, life support becomes difficult. In grafting by the method, adhesion of the cambium is performed not only on the side of the scion insertion but also on the tip side of the scion, so it can be confirmed that life can be maintained even if one site is blocked.

[0040]

【The invention's effect】

According to the present invention, the holes can be easily formed, and the labor for fixing the grafted portion with a clip is not required.
Since the holes are formed on the assumption of penetration, the fingers are not injured, and there are two adhesion points between the scion formation layer and the rootstock formation layer, and the scion is inserted through the rootstock and is stable. Therefore, the work can be performed quickly and safely, and the survival rate and the quality after the survival can be improved.
