Description

  The present invention relates to a graft holder used when grafting seedlings such as tomatoes, eggplants, and peppers.

Traditionally, a technique called grafting has been used to avoid soil-borne diseases and insect damage of cultivated vegetables and to enable continuous cropping.
For example, a watermelon grafts a seedling using Yugao, Togan and pumpkin as rootstock. Cucumbers also use pumpkins and black mushrooms as rootstocks. Even in melon, pumpkin is often used. For tomatoes and eggplants, different varieties are used.

  One method of grafting is to make diagonal cuts at the upper end of the rootstock and the lower end of the panicle, and join them so that the cut ends are in close contact with each other. Both were fixed between. After a few days, the roots of rootstock and hogi are settled, and the nutrients from the rootstock are sent to hogi to grow.

However, the above-mentioned graft clip is composed of a pair of clamping pieces and a spring, and its structure is complicated and expensive. In particular, cultivating farmers use tens of thousands of pieces, so the cost burden is large. In addition, grafting clips must be removed at some point because when the grafted seedlings grow, they compress the joints and prevent growth. If the effort is troublesome and you forget to remove it, the growth of the seedling will be hindered.
From such a viewpoint, a graft holding tool using plastic, particularly soft plastic, has come to be used.

  For example, Patent Document 1 discloses a graft support device in which a cut portion (a split) is provided from one end portion to the other end portion of a degradable plastic cylindrical body that holds the outer periphery of a joining portion of a rootstock and a hogi. Is described.

  Patent Document 2 describes a grafting tool for a seedling in which a cut line or notch (break) is provided in an elastic tubular body from the upper end surface to the lower end surface, and a communication groove is formed on the inner periphery of the elastic tubular body. Yes.

  In Patent Document 3, a transparent or translucent elastic cylindrical body is provided with a cut line or notch (break) from the upper end surface to the lower end surface, and the elastic cylindrical body is thicker than the upper part and the lower part. A seedling grafting tool having an overall barrel shape is described.

  The basic shape of this type of graft holder is shown in FIG. FIG. 9A is a perspective view, FIG. 9B is a front view, and FIG. 9C is a plan view. In the figure, the graft holder 20 is formed by forming a crack 22 on the side surface of the elastic cylindrical body 21 from the upper end surface to the lower end surface. When performing jointing, both the rootstock A and the hogi B are cut obliquely as shown in FIG. 10, and the grafting holder 20 is first attached to the rootstock A. Subsequently, it inserts in the inside of the holding tool 20 for grafting so that the cutting direction of the hogi B may coincide with the rootstock A. As a result, the grafted graft shown in FIG. 11 is formed.

  However, with this conventional grafting fixture 20, it is difficult to confirm whether or not the diagonal cuts of the rootstock and the cuts of the diagonal direction of the rootstock are well aligned when performing grafting work. There's a problem.
