Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of a double clip for grafting that is effective for simply and quickly grafting crops.

(Prior Art) Grafting of crops that has been conventionally performed is generally a split grafting method. This involves making a V-shaped notch in the rootstock, cutting the lower end of the scion into a tapered shape, inserting the lower end of the scion into the notch in the rootstock and joining it together, and securing the joined part with clips from the outside. This is a grafting method.

Regarding the clips used in this method,
Already published in 1982-25336, 49-23422, 58-70747, and 59-30909.
This method has been proposed in Japanese Utility Model Publication No. 57-8681, etc.

However, the split splicing method has a problem in that it requires a considerable amount of time to make a V-shaped cut in the rootstock and to cut the lower end of the scion into a tapered shape.

Therefore, in order to improve the efficiency of grafting work, a method of cutting the stems of both rootstock and scion almost horizontally and grafting them (hereinafter referred to as the "flat grafting method") was investigated. The reliability of this grafting method has been greatly improved by using medical grade adhesives during the grafting process.
The method has already been disclosed in "Agriculture and Horticulture" (Vol. 63, No. 10 (1988), pp. 70-76).

(Problems to be Solved by the Invention) An object of the present invention is to provide a double clip for grafting that is effective for carrying out the above-mentioned grafting method more simply and efficiently.

(Means for Solving the Problems) The present invention provides a method for grafting that includes a clip that holds the stem of a rootstock for grafting, a clip that holds the stem of a scion, and a supporting member that supports both clips with a gap between them. The gist is a double clip.

(Embodiment) A more detailed explanation will be given with reference to a drawing showing an embodiment of the double clip for grafting of the present invention.
is the double clip for grafting of the present invention, and 2
is a clip that holds the stem of the rootstock, and 3 is a clip that holds the stem of the rootstock.
This is a clip that holds the scion stem. Reference numeral 4 denotes a support member that supports both clips 2 and 3 with a gap between them, and the clips 2 and 3 are fixed to both ends of the support member 4. Both clips 2 and 3 may be of the same shape, but of course, they may also be of different shapes. In the embodiment shown in the drawings, both clips 2 and 3 have the same shape, so for convenience of explanation, the same members are given the same reference numerals.

5 and 5' are holding members for the clips 2 and 3;
6 and 6' are the same knob members, and 7 is a spring ring. The clips 2 and 3 can open the holding members 5 and 5' around the contact point 8 by pressing the knob members 6 and 6' with fingers, respectively.

Next, how to use the double clip 1 for grafting will be explained. First, prepare a rootstock and a scion whose stems have been cut almost horizontally. Next, open the clamping members 5 and 5' by pressing the knob members 6 and 6' of the clip 2 with your fingers, and while cutting the stem of the rootstock, Pinch and release your fingers. By doing this, the stem of the rootstock is held between the holding members 5, 5' of the clip 2, and the cut portion of the upper end of the stem protrudes above the holding members 5, 5'. Become.

Next, hold the knob members 6, 6' of the clip 3 with your fingers to open the clamping members 5, 5', insert the scion stem between them, and press the cut surface of the rootstock and the cut surface of the scion closely together. After setting the knob members 6, 6'
Let go of your finger. In this way, the cut surface of the rootstock and the cut surface of the scion are in close contact with each other and are fixed by the double clip 1 for grafting of the present invention.

In this way, with the rootstock and scion fixed using the grafting dove clip 1 of the present invention, a quick-drying adhesive (especially a pharmaceutical adhesive) is applied around the area where both cut surfaces are in close contact with each other. ) can be easily applied.

As a method of using the pharmaceutical adhesive, it is also possible to apply it to the cut surface of the rootstock or scion in advance, and then graft the tree by bringing both cut surfaces into close contact with each other.

Additionally, depending on the type of crop, you may not need to use any adhesives at all to ensure rooting by simply placing the cut surfaces of the rootstock and scion in close contact using the grafting double clip of the present invention. It is possible.

(Effects) Table 1 shows a comparison between using and not using the double lip for grafting of the present invention when grafting cucumbers by the flat method using a quick-drying adhesive. That's right.

Table 1 Time required for grafting 100 grafts Using the double clip of the present invention 47 minutes Same as above Not using 1 hour 36 minutes As is clear from Table 1, using the double clip of the present invention for grafting improves work efficiency. This allows for significant improvements.
