Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grafting method and an apparatus therefor, and more particularly to a grafted seedling obtained by joining a cutting part obtained by cutting and removing the spikes of a rootstock seedling with a cutting part cut from the seedlings. The present invention relates to a grafting method for continuously manufacturing and a device therefor.

[0002]

2. Description of the Related Art A grafting device of this type is a device for joining a cutting portion cut from a scion seedling to a stand portion obtained by cutting and removing the cutting portion from a rootstock seedling at a predetermined grafting position. As a conventional example, for example, JP-A-7-250565 (hereinafter referred to as a first conventional example), JP-A-7-227145 (hereinafter referred to as a second conventional example), and JP-A-5-219.
The one described in Japanese Patent No. 835 (hereinafter referred to as a third conventional example) is known.

According to the first conventional example, the cut surface of the rootstock without cultivating soil and the cut surface of the scion are closely joined, and the joined portion is joined and held by a holder to obtain a grafted seedling. A large amount of grafted seedlings can be efficiently attached by putting the seedlings in a vat-shaped container so that their roots come into contact with water, and by putting them in a survival promoting device in which the temperature, humidity, light amount, etc. are adjusted to cure.

According to the second conventional example, the scion conveying line, the rootstock conveying line, and the grafted seedling conveying line are arranged in parallel, and the scion seedlings, the rootstock seedlings, and the grafted seedlings are conveyed in each line. The gate-shaped frame, which is placed so as to cross the line and straddles the upper part of each line, is equipped with a mechanism for cutting the hypocotyl of each seedling, and cuts according to the height dimension of the scion seedling. The height can be adjusted.

According to the third conventional example, an upper seedling receiving member for preventing bending of the spikelet seedlings and a lower seedling receiving member are provided on the spiked carrying arm, and these upper seedling receiving member and lower seedling receiving member are provided. By rotating it so as to pass through the member, the cutting precision of the seedlings is improved while preventing the bending of the seedlings.

[0006]

However, in the grafting process, in order to increase the survival rate, for example, a rootstock seedling was cut at a predetermined position above its cotyledons to remove the spikes, It is common to join the ears cut from the scion seedling, but for that purpose, it is preferable to surely grasp the cotyledon position that should serve as a reference for cutting the hypocotyl.

[0007] However, in the above-mentioned conventional examples, there is no idea that the cotyledon is left to be cut, and therefore, there is no such thing as cutting a predetermined position from the cotyledon with the cotyledon position as a reference. For this reason, the cutting position of the hypocotyl varies depending on the height of the seedlings, and the cutting work becomes complicated, making it difficult to process a large amount of grafts, which in turn affects the survival rate.

The present invention has been made to solve the above problems, and an object thereof is to make it possible to cut the hypocotyl at a predetermined position with reference to the cotyledons of a rootstock seedling and a scion seedling. An object of the present invention is to provide a grafting method and apparatus capable of simultaneously processing a large number of grafted seedlings.
