Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for growing Nanten to a larger size in a much shorter period of time than normal ones.

In general, the Nanten tree does not grow very large, about 200 to 300
Even if the tree is 0 years old, its trunk circumference is 10 to 20 mm at its thickest point.
It is about Cm.

It is thought that this is because the Nanten tree does not grow as a single trunk, but instead grows in divisions, so it is difficult to see the degree of growth in the thickness and height of the trunk over time.

From this point of view, the inventor inferred that if the Nanten tree was allowed to grow as a single trunk, a larger Nanten tree than the present one could be obtained, and as a result of continued research, the inventor discovered that the Honbanohiragi Nanten (
When the Korean southern sky is grafted onto the Korean southern sky (hereinafter referred to as the Korean southern sky), there is almost no difference in the roots of the Korean southern sky, but
It has been found that when a Japanese hiragana is grafted onto a Korean southern tree and grown, its roots grow thicker than would be possible with a normal Korean southern tree.

Therefore, this time, I grafted a normal southern sky onto the Hiragi southern sky, which was grafted onto a Korean southern sky.

It was then discovered that this Nanten tree grows as a single trunk without dividing.

The present invention was developed based on these results, and its purpose is to provide a novel method for growing giant southern sky in a short period of time.

That is, the present invention grafts Hiragi nanten to Hosobano holly nanten, and then grafts Hiragi nanten to Hiragi nanten.
And let it grow as a single tree with the main part as the southern sky,
It is characterized by the fact that three types of trees are grafted together into a single tree to grow a gigantic southern sky.

The method of the present invention will be described below based on Examples.

1 is Hongbanohiragi Nanten (scientific name Ma), which is called Korean Nanten.
honia fortunei) and its lawn 2
(cut off the part slightly above the tree's hairline from the ground),
Mahonia jo (scientific name: Mahonia jo)
ponica) 3 (Fig. 1).

The Hosobanohiragi Nanten used here is a shrub with a height of about 2 m that is native to China.The trunk is sparsely branched and stands upright, and the leaves are 12 to 15 cm long and separate compound leaves, and there are 7 to 9 leaflets on the edges. It has a low bush and blooms in yellow flowers around September, and bears indigo-black fruits the following spring.

Next, the grafting of Korea Nanten 1 and Hiragi Nanten 3 will be explained in detail.

Usually, cuttings of Korean Nanten 1 are taken just before germination from early to late Sankata, and the branches of the previous year are cut to a length of about 10 to 20 CrfL, and the lower ends are shaved into a wedge shape.

Then, add 1/3 to 1 liter of the length of the scion in ordinary soil for cuttings.
/ Insert the 2nd place vertically.

After rooting, it is left as it is, transplanted and fertilized before germination in early to late March of the following year, and used as Kinuta withered wood around March to April of the following year.

The grown Korean Nanten 1 can be used as a dead tree at any time thereafter.

The success rate of the cuttings taking root is almost 100% if Kanuma soil is used as the soil and a rooting agent is used, and it is about 80 to 90% even if the cuttings are placed in ordinary soil without any chemical treatment.

Then, from late March to early April, I cut out 5 to 10 cIrLIJJ of the last year's vigorous Hiragi Nanten 3 board strips (the thickness of a pencil is just right) to the condensed water of Korean Nanten 1. Graft using the circumferential method.

(It is also possible to graft by the pumping method.

) Fertilize this without pruning for 3 to 10 years, grow the roots and trunk as thick as possible, and use this as Nanten water.

When the trunk 4 of Hiraki Nanten 3 became thick enough to be suitable for grafting through the above-mentioned fertilization (Figure 2), it was cut off leaving about 7 to 10 cTL above from the grafted part 5 to Korean Nanten 1, and water was removed.
At the 3' cut, there is a southern sky (scientific name: Nandiadomesti).
ca) Graft 5 (Figure 3).

For Nanten 6, select the last year's board that is particularly vigorous, and use a scion of about 5 to 1 OCrfL (the grafting result is good if you use the top head) to graft the same. Graft the tree using the circumferential grafting method in the area where the water condenses.

If you scrape off and fertilize the jago (small buds that germinate from the dead wood) of Chosun Nanten 1 and Hiraki Nanten 3, Nanten 6 will not branch and will only grow as a single tree.

As mentioned above, when the southern sky 6 reaches the Hiragi southern sky 3, this southern sky 6
The plant grows as a single trunk without dividing, so if we manage pests and diseases in a timely manner and apply plenty of fertilizer, the trunk circumference will be 20 to 25 cr, IL 1, and tree height 4 in 15 to 20 years.
It has grown to about m.

Therefore, compared to the ungrafted Nanten, which grows only about 10 to 20 crrL in trunk circumference in 200 to 300 years, the trunk circumference of the Nanten grown by the method of the present invention is 1/20 to 1/1
Since it grows 1 to 2.5 times as thick in a period of 0, it can be said that this has paved the way for the industrial use of Nanten wood.

As described above, the present invention can greatly grow Nanten in a short period of time,
This has the effect of stably supplying high-quality, inexpensive southern wood.

Claims (1)

[Claims] 1. By grafting Hiragi nanten to Honbanohiragi nanten, and then grafting Hiragi nanten to Hiragi nanten, a gigantic hiragana nanten can be grown as a single tree with the roots as Honbanohiragi nanten, the trunk as Hiragi nanten, and the main part as Hiragi nanten. Raising method.
