Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating Yamabuki, and is applied to a method for cultivating Yamabuki for ornamental use such as bonsai.

[0002]

2. Description of the Related Art Yamabuki is generally known as a deciduous shrub of the family Rosaceae that grows naturally in mountains and the like. The height of the tree is 1-1.
It will be about 5 m long and will have yellow or white flowers from April to May. There are double-flowered or single-flowered petals,
The trunk is initially green and gray in old ones. Yamabuki is planted in houses and parks, and there are several cultivars. Conventionally, when cultivating such Yamabuki, the Yamabuki plant is appropriately cut and planted in a flowerbed or the like. When new shoots emerge from the roots and trunks, they begin to bloom in about two years.

[0003]

However, such Yamabuki is rarely cultivated for ornamental use because it has the following drawbacks. Subterranean roots circulate like bamboo and interfere with the growth of other plants, so when planted as garden trees, they can only be transplanted to the corners of the fence. When pruning the Yamabuki trunk, the root of the plant withers and dies, with poor flowering that year and the following year. Yamabuki does not bloom on the stem of the new shoots. Yamabuki trunk grows straight and becomes relatively long, so it is not suitable for potting. The stems of Yamabuki are long between each node and the inside is styrofoam-like, so if you cultivate them by cutting (splitting method), you will almost fail. Yamabuki is pine, maple, zelkova, mahashi,
It is weaker than bonsai flowers such as plums and cherry blossoms.

The present invention has been made in view of the above circumstances, and provides a method for cultivating Yamabuki, which makes it possible to grow Yamabuki by cuttings and easily enjoy Yamabuki by potting. The purpose is to do.

[0005]

Therefore, the method for cultivating Yamabuki according to the first aspect of the present invention is a method for cultivating Yamabuki with cuttings, and among the branches of the old trunk of Yamabuki, branches having 5 or more nodes. Is cut to make cuttings, and at least the third node counting from the cut side of the cuttings is inserted into the soil.

[0006] The branch of the old trunk means a branch of the trunk which has already been flowered. In Yamabuki, since the shoots grow and flowers after the second year, it is usually the old trunk if the branch is over two years old. The reason why the old trunk is used in this way is that if a non-old trunk is used, it is difficult for roots to attach even if cutting is performed and flowers are hard to bloom.

[0007] The reason why the branches having 5 or more nodes of the old trunk are used as cuttings is that the cuttings are likely to die and die unless the branches have at least 5 nodes. The length of cuttings differs depending on the position of the nodes on the old trunk, but when cuttings are cut with 4 cuttings or less, roots are less likely to take root. 3 from the cut end of the cuttings
The reason why the knots or more are inserted into the soil is that when the knots are less than 3 knots, the cuttings are not easily adapted to the soil and the roots are not easily attached.

Further, the method for cultivating Yamabuki according to the second aspect of the present invention is characterized in that a plurality of sprouts are grown on a predetermined portion of a stem of Yamabuki, and a nodule-shaped branch portion is formed at the portion. To do. When a branching part is formed in a predetermined part of the Yamabuki trunk,
The trunk from the root to the branching part becomes thicker, preventing the height of the tree from increasing. For example, when pruning shoots, if you leave multiple shoots at an appropriate height position and scratch all the shoots that extend to other parts, the part that left the shoots gradually swells and a nodule-shaped branching part. Is formed, and the branches radially extend to the branching portion. As a result, the entire tree has a rounded branch, which is suitable for making a bonsai tree as an ornamental Yamabuki.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 shows an example of cuttings of Yamabuki cuttings on the soil. The pot 3 contains a predetermined amount of soil 4, and the cuttings S are buried in the soil 5 to a predetermined depth. The cuttings S are obtained by cutting the branches of the Yamabuki old trunk. As shown in FIGS. 2 and 3, the branch E is cut so that the number of nodes is 5 or more, and the branches E1 to E3 up to three nodes counted from the cut side of the branch E are blown to remove the cuttings S. Finalize. It should be noted that the removed portion of the cuttings S may be soaked in an antiseptic solution and sterilized.

Small stones 6 are laid on the bottom of the pot 4, and the soil 4 is put on the pebbles 6 to sufficiently contain water. As the soil 4, it is desired to use one having a large moisturizing property, for example,
Soil, river sand, vermiculite and the like can be used. Alternatively, water moss may be used. As for the bowl 3, a plastic planter or the like may be used in addition to the unglazed pottery. In addition, the flowerpot can be made to bloom in the flowerpot with the smallest basic size.

When cuttings are to be made, cuttings S are inserted near the center of the soil 4. The cutting method is as shown in FIG. 1 so that the three nodes S1 to S3 from the lower end of the cuttings S are completely buried in the soil 4. The angle at which the cuttings S are inserted is preferably set substantially vertically, but is not particularly limited.

The cuttings are preferably carried out from the beginning of May to the end of June. This is because various bacteria are easily propagated in the soil from July to October, and it is likely that it takes a long time to put the roots in the soil from November to April.

Up to 3-4 months after cutting, once /
Water for about a day and give fertilizer, etc. if necessary. In this state, after 3 to 4 months have passed, when rooting is completed, the plant is replanted in a nutrient medium. Then, after replanting, the shoots are appropriately pruned every 1 week to 10 days.

Here, the amount of water to be supplied should be relatively large so that the soil 4 can sufficiently retain its moisture. In the case of ordinary flowering trees, if the water content is too high, the roots may rot, but in the case of Yamabuki, even if too much water is given, the roots do not rot and grow well. Therefore, for example, when the person who manages the cuttings is absent for a long period of time, by putting the bowl 3 in a bucket or the like containing water, the roots of the cuttings absorb the required amount of water and grow well. In this respect, Yamabuki is relatively easy to grow.

As described above, when the pruning of new shoots is continued, as shown in FIG. 4, the trunk 7 of Yamabuki gradually becomes thicker, and even if the branches or the like are pruned, the roots of the trunk do not die and die. Therefore, it is possible to create the ornamental Yamabuki by adjusting the shape of the branch to your liking. The pruned shoots are shown in Fig. 5.
As shown in, in addition to the buds 7 that grow on the stem of the cuttings S, the cuttings S
The buds 8 newly grow from the roots around the buds, but in order to grow the stem of the cuttings S more strongly, it is desirable to remove the buds 8 around the buds.

Next, a test example in which Yamabuki is cultivated by cuttings will be described. For cuttings with different types of stems and different numbers of nodes (Examples 1 to 4 and Comparative Examples 1 to 4),
A test was conducted as to whether or not the cuttings had roots.
The size of the pot, the type of soil, and the like were the same in all of Examples 1 to 4 and Comparative Examples 1 to 4. Table 1
Shows the type of trunk and the number of nodes.

[Table 1] Examples 1 to 4 are those obtained by cutting old stems of 5 or more nodes at a depth of 3 or more nodes, and Comparative Example 1 using cuttings of shoot stems that do not yet have flowers, Comparative Example 2 uses cuttings up to the second node, Comparative Example 3 uses cuttings of the old trunk of Section 4, and Comparative Example 4 uses old trunk of Section 3
The cuttings are made up to the turning point. The above Examples 1 to 4 and Comparative Examples 1 to 4 were given water once per day, and it was examined whether or not roots were attached to each cutting after 1 week to 10 days had elapsed.

As a result of the investigation, as shown in Table 1, Examples 1 to 4 have roots, whereas Comparative Examples 1 to 4 have no roots. That is, the cuttings did not take root unless they had 5 or more nodes, and even if the cuttings had 5 or more nodes, they did not take root unless the cuttings had a depth of 3 nodes or more.

Next, an example of creating an ornamental Yamabuki will be described.
An example of creating a bonsai tree using Yamabuki is shown in FIG. When making a bonsai tree, first, an old stem of Yamabuki is used for cutting, cutting is performed, and a root is attached to the cutting. After 1 week to 10 days, make sure that the roots are rooted and insert the cuttings into a bonsai pot.
Replant. At this time, the ground is prepared by laying a soil and a drainage. Regarding the position of the cuttings, for example, it is arranged in the center of the pot 10. The direction of inserting the cuttings may be appropriately inclined.
Then, the shoots extending from the cutting stem and the surrounding roots are pruned to grow the stem 12 thick. Regarding the method of pruning the new shoots, for example, all the new shoots are cut off while leaving the new shoots at a position of about 10 to 15 cm from the root of the cuttings.

If such pruning is continued, as shown in FIG. 6, the branching portion 14 of the cuttings bulges like a bump, and the branches radially extend to the branching portion 14. By appropriately pruning the extended branches, it is possible to create a bonsai with a rounded branch, without increasing the height. Moreover, since the cuttings of the old trunk are used, the Yamabuki flower 15 will also come to bloom relatively early.

Yamabuki shown in FIG. 7 is obtained by tailoring the trunk of a potted Yamabuki in a predetermined direction. Yamabuki Trunk 1
A nodule-shaped branching portion 17 is formed at the base of 6. Sprouts growing on other parts should be scratched monthly or yearly.

Next, FIGS. 8 and 9 show an example in which Yamabuki is tailored upward using a hanging pot. Fill the soil or drainage into a mesh-shaped container 20 made of wire or plastic as shown in FIG. 8 and plant rooted Yamabuki 21 at a position offset from the center. As shown in Fig. 9, since the sprout extends upward, picking the tip naturally creates a branch and improves its shape.
Flowers come from the first year.

FIGS. 10 and 11 show an example in which Yamabuki is tailored downward using a hanging pot. Yamabuki 31 with roots is planted in the center of a hanging pot type pot 30 as shown in FIG. The sprout grows straight, so the aluminum wire 32, which is the time when it became an old trunk, faces downward. Pick the shoots properly to balance the whole. In addition, the downward tailoring is generally
Vines and vines are known, but little is done in flowering trees.

[0023]

As described above, according to the method for cultivating Yamabuki of the present invention, it is possible to grow Yamabuki by cuttings. Therefore, a single tailor-made Yamabuki can be easily cultivated in a flowerpot, pot, hanging pot or the like. You can easily bring it into your house. In addition, the weakness of Yamabuki's trunk can be strengthened, and it can grow well with flowers and can be grown short, so you can enjoy not only cut flowers in the past, but also flowers and trees for a long time with evergreen bonsai. Further, unlike the conventional Yamabuki, since the trunk can be grown short and thick, there is an effect that even if the branches are pruned, the tree is unlikely to die and the tree can be made into a strong tree.
