DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grafting knife used for a grafting operation in which a rootstock having roots is spliced with a scion (grafting) consisting of branches, buds, etc., and more particularly to a stripping graft. A grafting knife suitable for use in the method.

[0002]

2. Description of the Related Art A grafting technique is indispensable in fruit tree cultivation. At the cultivation site, there are many scenes related to the renewal of varieties and the production of seedlings, and it is necessary to proliferate a large number of excellent test trees both in terms of management and in the case of trial research. In growing such excellent varieties, in the case of fruit trees, it is necessary to grow them by vegetative propagation. This vegetative propagation method includes grafting and cutting methods, but in the case of fruit trees, cuttings are difficult to breed except for some tree species such as grapes, and even grapes that are easy to use are exclusively from the viewpoint of phylloxera resistance. At present, the propagation depends on the grafting method.

[0003] As the grafting method, the cutting and grafting method is most often used, but depending on the type of tree and the timing, a splitting method, a stripping method, a belly method, or the like is also used. here,
In the peeling method among the several grafting methods described above, a rootstock of a relatively large diameter tree is peeled, and a scion (grafted spike) obtained by appropriately cutting a skin layer portion and a woody portion is inserted under the skin. It is a method, this method is relatively easy to graft, and the comparison of survival rate is not so different from the cutting and grafting method,
It is used for high graft renewal and some seedling production.

[0004]

However, conventionally,
There is only a general-purpose cutting knife having a straight blade as a cutting knife for use in the case of performing grafting by the peeling-off method, and depending on a part where grafting is performed in high graft renewal or the like, a general-purpose knife is not particularly used. Skill cutting and peeling operations may be difficult for a skilled person. Heretofore, there has been a “only” blade that can be used for the peeling operation, but this blade is not used in consideration of the grafting operation by the peeling method and is difficult to use.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide an unskilled person regardless of where the grafting is performed by the peeling method. In particular, it is an object of the present invention to provide a grafting knife which can easily perform a slitting operation, a peeling operation, and the like.

[0006]

In order to achieve the above-mentioned object, a grafting knife according to the present invention comprises a semicircular blade having an arcuate blade formed thereon, and the blade of the semicircular blade. A blade body, which is formed on a side opposite to the side on which is formed, and comprises a convex blade portion having a straight blade formed thereon, is attached and fixed to the tip of the grip handle. The semicircular blade is preferably eccentrically inclined to one side with respect to the grip handle, and the convex blade is preferably obliquely downward from the semicircular blade. It is protruded.

In the grafting blade according to the present invention having the above-described structure, when performing the grafting by the peeling method, the semicircular blade portion is closer to the grip handle portion of the arc-shaped blade. The part is used for cutting scion. In this case, the scions are scraped off, just as if you were sharpening a pencil with a knife. For this reason, cutting of the scion can be easily and accurately performed even by an unskilled person.

The other part of the arc-shaped blade (the part eccentrically inclined away from the grip handle) is used for cutting a stock. In this case, the blade portion may be pressed against a required part of the stock and moved up and down or rotated. In this case, the blade portion is in an arc shape, and since the semicircular blade portion is eccentrically inclined with respect to the handle portion, the degree of freedom of the attitude and position of the blade with respect to the stock is increased,
This makes it easier to press the blade portion against the stock, and as a result, even in a site where it was difficult with a conventional cutting knife, or even an unskilled person, the cutting operation can be easily and reliably performed.

[0009] The convex blade portion is used for peeling operation. In this case, for example, the skin is pushed down from above the skin portion to be peeled, or the skin is peeled off by twisting. Here, since the convex blade portion is projected obliquely downward at a position deviated from (on the center line of) the grip handle portion, the convex blade portion can be easily formed on the upper surface of the stock (cutting portion). Can be pressed against, and the peeling operation can be performed with a small force based on the principle of leverage. As a result, even an unskilled person,
The peeling operation can be performed easily and reliably.

As described above, the blade for grafting according to the present invention has a structure in which three types of blades for cutting a scion, cutting a rootstock, and peeling are combined. As understood from the above, each blade has a reasonable configuration according to the application, so by using this,
The grafting by the peeling-off method can be performed very easily, quickly, and efficiently without requiring anyone to master or train.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of a grafting knife according to the present invention. The grafting blade 1 of the illustrated embodiment is mainly used for the peeling and joining method, and includes a semicircular blade portion 3A on which an arc-shaped blade 4 is formed, and the blade 4 of the semicircular blade portion 3A. A blade body 3 comprising a convex blade portion 5 having a straight blade 6 protrudingly provided on a side opposite to the side on which the blade is formed is attached and fixed to the tip of the grip handle portion 2. I have.

The semicircular blade 3A is provided with the grip handle 2
The convex blade portion 5 is eccentrically inclined to one side (the right side in the drawing) with respect to, and the convex blade portion 5 is projected obliquely downward so as to be orthogonal to the semicircular blade portion 3A. The grafting blade 1 of the present embodiment having such a configuration, when performing grafting by the peeling method, is used for the grip handle portion 2 of the arc-shaped blade 4 of the semicircular blade portion 3A. The close part 4B is used for cutting the scion. In this case, the scions are scraped off, just as if you were sharpening a pencil with a knife. For this reason, cutting of the scion can be easily and accurately performed even by an unskilled person.

Another part 4A of the arc-shaped blade 4
(The part eccentrically inclined away from the grip handle 2)
Used for cutting rootstocks. In this case, the blade part 4
What is necessary is just to press A to a required part of a stock, and to move up and down or to rotate it. In this case, since the blade portion has an arc shape and the semi-circular blade portion 3A is eccentrically inclined with respect to the handle portion 2, the degree of freedom of the attitude and position of the blade 1 with respect to the stock becomes high. At the same time, it becomes easier to press the blade portion 4A against the stock, and as a result, it is possible to easily and surely perform a slitting operation or the like even in a part that was difficult with the conventional cutting knife and even for an unskilled person. Can be.

The convex blade 5 is used for a peeling operation. In this case, for example, the skin is pushed down from above the skin portion to be peeled, or the skin is peeled off by twisting. Here, since the convex blade portion 5 is projected obliquely downward at a position deviated from the grip handle portion (on the center line) 2, the convex blade portion is formed on the upper surface of the stock (cutting portion). 5 can be pressed easily, and the peeling operation can be performed with a small force based on the principle of leverage. As a result, even an unskilled person can easily and reliably perform the peeling operation.

Thus, the grafting blade 1 of the present invention has a structure in which three types of blades for cutting a scion, cutting a rootstock, and peeling are combined. As can be understood from the description, since each blade portion has a rational configuration according to the application, by using this, anyone can use the grafting method by the peeling method without requiring mastery and skill. Very easily and quickly and efficiently. In addition, in addition to the above-mentioned use examples, the grafting blade according to the present invention is, for example, as shown in FIG. It can also be used for making cuts for branches.

[0016]

As will be understood from the above description, according to the present invention, no matter where the grafting is performed by the peeling method or even if it is an unskilled person, the cutting operation can be performed. It is possible to provide a blade for a graft that can easily perform a peeling operation and the like.
