Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to kiwi and a method for cultivating the same.

[0002]

2. Description of the Related Art Hitherto, in kiwi, there are male trees to which male flowers are attached and female trees to which female flowers are attached. The pollen of the male flowers attaches to the female flowers, so that the female flowers bear fruit.

[0003]

However, in the conventional kiwi, if a male tree does not exist, even if a flower blooms on a female tree, it does not bear fruit.
In order to get many fruits, it was necessary to artificially mate.

The present invention has been made in view of the above facts, and an object of the present invention is to provide a new kiwi which can bear fruit without crossing.

[0005]

According to the present invention, there is provided a kiwi in which a male tree or a female tree is grafted with a female tree or a male tree, and the grafted female tree bears fruits substantially without crossing.

Further, according to the present invention, there is provided a method for cultivating kiwi, in which a male or female tree is grafted with a female or male tree, and the grafted female tree is allowed to bear fruit substantially without crossing. To be done.

[0007]

[Operation] When a male or female tree is grafted with a female or male tree,
The flower bloomed on the female tree bears fruit without crossing, and the fruit can be planted with a single tree.

[0008]

The kiwi and its cultivation method according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a kiwi female tree, and FIG. 2 shows a kiwi female tree. Female tree 2 has female flowers, and male tree 4
A male flower blooms in.

The kiwi of FIG. 3 is cultivated by grafting the male tree of FIG. 2 with the female tree of FIG. With reference to FIGS. 3 and 4, for example, the tip of male tree 4 having a height of about 150 cm is cut by about 50 cm, and the height thereof is set to about 100 cm. Also, cut the tip of the female tree 2 to about 7 cm,
This female tree 2 is grafted onto the male tree 4.

Grafting can be performed as shown in FIG. 4, for example. That is, the male tree 4 is cut so that the cut surface becomes the inclined surface 6. The angle α of the inclined surface 6 is preferably about 30 to 60 degrees so that the grafting is surely performed. Also,
The female tree 2 is also cut so that the cut surface becomes the inclined surface 8 corresponding to the inclined surface 6, and the inclined surface 6 is the cutting inclined surface 6 of the male tree 4.
Placed on. Then, the female tree 2 is connected to the male tree 4 by a thin rope 10 so as not to come off. Instead of the rope 10, bamboo skin, string, tape or the like can be used.

When grafting is carried out and the female tree 2 is firmly attached to the male tree 4, the female tree 2 extends from the male tree 4 and the male tree 1 is attached to the male tree 4.
2 bloom, and female flower 14 blooms on female tree 2. And female tree 2
The female flower 14 that bloomed on the tree becomes a fruit, and this fruit grows greatly to become a kiwi fruit.

Since this is the case, the female flowers 14 of the female tree 2 grafted on the male tree 4 are practically all fruits without crossing. Therefore, a single tree can produce fruit, and even a relatively small land such as a garden can produce fruit.

The grafting was actually carried out and the following results were obtained.

Around May 1989, six male trees were grafted with female trees. 50 for each Ogi
It was cut to about cm, and cut so that the cut surface was an inclined surface of about 45 degrees. In addition, each female tree was cut into about 7 cm so that the cut surface was an inclined surface of about 45 degrees. Then, the female trees were placed on the cut surfaces of the male trees, respectively, and grafted with tape.

When examined around May 1990, 5 of the 6 grafted trees failed and the female tree died, but one succeeded and the female tree grew to about 80 cm. ..
However, in this year, the female tree did not sprout,
Therefore it did not bear fruit. One of the successful grafts had a new flower bud around April 1991, and this flower bud bloomed around June of that year. In the example, although the grafting was successful, about 150 male flowers bloomed in the male tree part and 18 female flowers bloomed in the female tree part.

The fruits attached to the female flowers that bloomed around June grew until around September of that year and became edible as kiwifruit in November. Then, all 18 female flowers blooming on the female tree became fruit, and 18 kiwifruits were taken from the female tree.

From the above results, it is possible to graft a female tree on a male tree and obtain substantially all the fruits from the female flowers blooming on the grafted female tree, and the kiwi fruits can be obtained substantially without mating. Be done.

Although one embodiment of the kiwi and the cultivation method therefor according to the present invention has been described above, the present invention is not limited to such an embodiment, and various variations and modifications can be made without departing from the scope of the present invention. Is possible.

For example, in the illustrated embodiment, the male tree is contacted with the female tree, but conversely, the male tree is contacted with the female tree to achieve the same effect.

[0021]

As described above, according to the present invention, substantially all female flowers blooming on a female tree can be obtained by grafting a male tree or a female tree with a female tree or a male tree without performing crossing. The fruit is obtained.
