Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree growing method for growing trees by cutting.

[0002]

2. Description of the Related Art Trees are mainly cultivated by germinating seeds to grow seedlings, and by using branches cut from a parent tree (also called mother tree) as stalks, these stalks are used as soil floors. There is a method of cutting and rooting, but the method of cutting is suitable for growing trees with exactly the same type and sex (different male and female) as the parent tree.

FIG. 5 shows a conventional tree growing method using cuttings. Conventionally, a bottomless cylindrical wooden frame 1 is placed on the ground G, and a drainage such as Kanuma soil is placed in the wooden frame 1. The soil floor 2 is made of good soil, and the spikes A are inserted into the soil floor 2, and the soil floor 2 is constantly watered, and the spikelets A are grown until the roots a are sufficiently emerged.

[0004]

By the way, in the tree cultivation by the above cuttings, since the scion A withers when the water content in the soil bed 2 decreases, the water content necessary for the growth of the scion A is always kept in the soil bed. It must be included in 2.

This is particularly important in the period until rooting. That is, in the case of raising trees by cuttings, the scion A is usually cut in spring (around April) and rooted in autumn (around October).

After rooting to some extent, the scion A absorbs water from the root a extending into the soil floor 2, so that the scion A will die immediately even if the soil bed 2 is low in water. However, since the roots do not absorb water before rooting, especially in the high temperature season of summer, when the water content in the soil bed 2 becomes low, the scion A dies immediately.

For this reason, conventionally, watering is carried out while observing the dryness of the soil floor 2, but this watering can only be done manually, and in the high temperature period of summer, watering is carried out almost every day. It is quite difficult to do it completely, because you have to carry out a spear and forget to water it
Sometimes withered.

[0008] Actually, the inventor of the present invention has continued to grow the first-ranked tree (Araragi) by cuttings for 30 years by the above-mentioned conventional method. The ratio is 60 to 8 even in a relatively good year
It was about 0%.

It is an object of the present invention to provide a tree growing method capable of rooting a scion with a high probability by always including a sufficient amount of water in the soil floor without using nerves for watering. It is what

[0010]

The method for growing trees according to the present invention is characterized in that the cutting vessel has a water storage tray at the bottom and a drainage portion for discharging water exceeding the allowable water storage capacity to the outside. Make a well-drained soil floor from the inside of the reservoir to above it, and insert the spikes above the drainage part of the soil floor, and supply water to the reservoir to keep the water in the reservoir at all times. It is characterized in that it is kept in a state of being accumulated, and the water is sucked up to the soil floor, and the roots of the spikes are taken out in the soil soil containing water.

[0011]

According to the tree growing method of the present invention, water is always stored in the water storage tray at the bottom of the cutting container, and the water is sucked up to the soil floor. Even if it is not necessary, it is possible to always have sufficient water content in the soil floor, and the maximum water level stored in the water storage tray is regulated by the drainage of excess water from the drainage section, Since the cuttings are inserted into the portion above the drainage part of the soil floor formed in the cuttings container, the cuttings will not be soaked in the water in the water storage tray and be spoiled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. FIG. 1 is a cross-sectional view showing a method of growing trees according to this embodiment, in which cuttings are put into a cuttings container, and FIG. 2 is a perspective view of an apparatus used for growing trees.

First, the structure of the tree growing apparatus shown in FIG. 2 will be described. This growing apparatus comprises a cutting vessel 10 and a water supply system 16 for supplying water to a water storage tray 10a at the bottom of the cutting vessel 10. ing.

As shown in FIGS. 1 and 2, the cuttings container 10 is a flat-bottomed box composed of a bottom plate and a rectangular tube-shaped frame body. The drainage ports 11 in the shape of horizontal slits are provided slightly above the bottom surface and are provided at appropriate intervals on the entire circumference of the cuttings container 10.

The bottom of the cutting container 10, that is, the portion below the drainage port 11, serves as a water storage tray 10a for always storing water, and the region above the drainage port 11 in the cuttings container 10 is provided. Is the cutting area of the scion A.

The cutting container 10 is made of a wooden box or a resin molded product, and the height H from the inner bottom surface of the water tray 10a to the upper edge of the cutting container 10 is about 250-.
300 mm, the height (depth of the water storage tray 10a) h from the inner bottom surface of the water storage tray 10a to the lower edge of the drainage port 11 is about 50 mm,
The height (slit width) d of the drainage port 11 is about 5 mm.

The water supply system 16 is a water tank 1 installed at a position higher than the installation level of the cutting vessel 10.
7, a water supply pipe 18 for supplying water from the water tank 17 to the cutting container 10, and a water amount adjusting valve 19 provided on the water supply pipe 18.

The tip end side of the water supply pipe 18 is bent downward and inserted into the cutting tree container 10 along the inner wall thereof, and the tip end thereof is the water tray 1 at the bottom of the cutting tree container 10.
It opens in 0a.

The water supply system 16 stores water in a water tank 17, and the water is always stored in a fixed amount in the cutting container 1 described above.
The water is supplied to the water storage tray 10a of 0, and the water supply amount is set to such an amount that the water accumulated in the water storage tray 10a overflows from the drainage port 11 to the outside very little by little.

Although only one cutting vessel 10 is shown in FIG. 2, when water is supplied from one water tank 17 to a plurality of cutting vessels, the water supply pipe 18 is branched into a plurality of cutting vessels. Just fill the container with water.

Although not shown in FIG. 2, the water stored in the water tank 17 is, for example, tap water (which may be pumped from a well or the like) which is opened / closed according to a change in water level in the tank. It may be automatically replenished via a valve with a float.

Next, a tree growing method using the above growing apparatus will be described. In this growing method, as shown in FIG. 1, the cutting vessel 10 is provided with a water storage tray 10 at the bottom thereof.
A soil floor 20 with good drainage is made from inside a above it (near the upper edge of the box 10), and a cutting area of this soil floor 20,
That is, the scion A is cut and inserted into the area above the drainage port 11. The soil floor 20 is made of well-drained soil such as Kanuma soil, but the soil floor of the water storage tray 10a may be made by mixing well-drained soil with small stones.

After the cuttings A have been cut, water is constantly accumulated in the water storage tray 10a by constantly supplying a constant amount of water from the water supply system 16 to the water storage tray 10a at the bottom of the cutting cutting container 10. Keep it in a state of being
The root a of the scion A in the soil bed containing water.

In this growing method, when the spikelets A are to be cut into the soil floor 20, it is desirable that the soil floor 20 be watered over the soil to allow the soil floor 20 to contain a certain amount of water. , After that, cutting container 10 from water supply system 16
All that is necessary is to supply water to the water storage tray 10a at the bottom of the.

In this growing method, the cutting container 10
Since water is always stored in the water storage tray 10a at the bottom of the tank and the water is sucked up to the soil floor 20, it is necessary to always contain sufficient water in the soil floor 20 without using nerves for watering. Can be kept.

On the other hand, common knowledge in the horticultural industry is that if roots of soil-planting plants are soaked in water for a long period of time, root rot will occur. Therefore, all commercially available flower pots have drained water at the bottom. It is said that holes are provided to prevent water from accumulating inside, and even in the conventional tree growing method shown in FIG. 5, the water inside the cutting container is used by using a bottomless wooden frame. It is soaked in the ground to prevent water from accumulating inside the cutting container.

On the contrary, in the growing method of the above-mentioned embodiment, the cutting vessel 10 having the water tray 10a at the bottom is used, but the maximum water level stored in the water tray 10a of the cutting vessel 10 is Excessive water exceeding the allowable storage amount is regulated by being drained to the outside from the drainage port 11, and the soil floor 20 formed in the cutting container 10 has a spike on the portion above the drainage port 11. Since A is inserted, the scion A will not be soaked in the water in the water storage tray 10a and be spoiled.

Therefore, according to the above-mentioned growing method, the scion A can be rooted with a high probability. In addition, when the scion A is grown under the open air, the cutting container 1
Since rainwater permeates into the soil floor 20 in 0, the amount of water entering the water storage tray 10a is larger than the amount of water supplied from the water supply system 16, but the length and number of the drainage ports 11 are set so as to obtain a sufficient amount of drainage. By so doing, the water level in the water storage tray 10a will not rise above the drainage port 11 and the spike A will not be submerged in the water. However, when the amount of rainfall is extremely large, it is desirable to adjust the water amount adjusting valve 19 to reduce the amount of water supplied from the water supply system 16 or to temporarily stop the water supply.

When roots A start rooting, among the roots a that extend from the root A into the soil floor 20, the tip of the root that extends downward enters the water tray 10a and becomes water. It may be soaked, but by that time, the spikelets A have been fully rooted, so during the period when the tip of the root is submerged in water, remove the rooted spikelets A from the cuttings container 10. Since it takes a very short time to plant trees, root rot hardly occurs even when the tip of the root is immersed in the water in the water storage tray 10a.

As shown in FIG. 1, a water-permeable root stop sheet made of a resin film or the like, which is located slightly above the drainage port 11 in the soil floor 20 and is provided with a large number of water passage holes. If 21 is laid (layed when the soil floor 20 is made), the root a emerging from the spike A will not enter the soil floor portion in the water storage tray 10a and be submerged in water.

Moreover, in the above growing method, the water tank 17
Since water is automatically supplied from the water supply system 16 equipped with the water to the water storage tray 10a at the bottom of the cutting container 10, constant watering of the soil floor 20 in the cutting container 10 is completely unnecessary. Therefore, the labor required for watering the soil floor 20 can be reduced.

In the above embodiment, the drainage port 11 is provided on the side surface of the flat bottom box as the cutting vessel container 10.
Although the portion below 1 was used as the water storage tray 10a,
The cutting-vessel container may have any configuration as long as it has a water tray at the bottom and a drainage portion for draining water exceeding the allowable water storage amount to the outside.

FIGS. 3 and 4 show another example of the cuttings container used in the above-mentioned growing method. The cuttings container 10 shown in FIG. 3 is a bottom plate of a flat bottom box, which is slightly above the inner bottom surface thereof. The drain pipe 12 is made to project and penetrate, and the portion below the drain pipe 12 at the bottom of the box is the water storage tray 10a.

The cutting tree container 10 shown in FIG. 4 is composed of two members: a bottomless cylindrical frame 13 and a water storage tray 14 having a width slightly smaller than the inner width of the frame 13. The cutting container 10 is configured by placing the frame 13 and the water storage tray 14 on the ground G so as to surround the water storage tray 14 at the lower portion of the frame 13, and the outer periphery of the water storage tray 14 and the frame 13 The gap between the inner peripheral surface of and is used as the drainage channel 15.

The cutting tree container 10 shown in FIG. 4 may be constructed by placing the frame 13 and the water storage tray 14 on a water-permeable material such as a sling. Also, FIG.
In the cutting container 10 shown in FIG. 4, the water storage tray 14 has a width slightly smaller than the inner width of the frame body 13. However, the width of the water storage tray 14 is set to be substantially the same as the width of the frame body 13, and The frame body 13 may be supported by providing an appropriate gap on 14 and the gap between the upper edge of the water storage tray 14 and the lower edge of the frame body 13 may be used as the drainage portion.

Further, in the above embodiment, the water is automatically supplied to the water storage tray 10a at the bottom of the cuttings container 10, but the water is supplied to the water storage tray 10a manually.
Alternatively, the water may be supplied from above to flow into the water storage tray 10a.

In that case, the amount of water accumulated in the water storage tray 10a decreases as the water is sucked up into the soil floor 20, but when the cutting container 10 is supplied with water, the water is drained from the drainage port 11. Until the water overflows, that is, if the water is fully filled in the water storage tray 10a, even in the high temperature summer,
Since the water is stored in the water storage tray 10a for several days, the next water supply may be performed during that time, so there is no need to water the water every day.

[0038]

According to the tree growing method of the present invention, water is always stored in the water tray at the bottom of the cutting vessel,
Since the water is sucked up to the soil floor, it is possible to always have sufficient water in the soil floor without using the nerves for watering, and the water stored in the water storage tray. The maximum water level is regulated by the excess water drained from the drainage part, and the cuttings are cut because the cuttings are cut into the part above the drainage part of the soil floor created in the cutting container. It is not soaked in water in the water storage dish and rotted, and therefore the scion can be rooted with a high probability.
