Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for raising ornamental plants and ornamental fish, and more particularly to maintaining the color of flowers and / or leaves of ornamental plants and the body color of ornamental fish at a desired color tone and density. The present invention relates to a method for raising ornamental plants and ornamental fish that can be raised.

[0002]

BACKGROUND OF THE INVENTION Ornamental plants and ornamental fish are grown indoors to appreciate leaf color, flower color or body color.

For example, as ornamental plants, orchidaceae plants, taro plants such as colors, rose plants such as roses,
In addition to plants such as Amaryllis that appreciate the flowering flower color of the Amaryllidaceae plant, there are also herbaceous plants that appreciate the leaf color such as begonia, caradium, hen head, Omoto, some orchids, sardine, and Aoki.

[0004] Also, as the fish for appreciation, Japanese gold,
Goldfish such as Ranchu or Nishikigoi can be mentioned. The flower color, leaf color and body color of these ornamental plants and ornamental fish greatly affect their quality.

However, the color tone, color density, etc. of these ornamental plants and ornamental fish have sometimes deteriorated when grown in a house. In addition, when these ornamental plants and ornamental fish are commercially cultivated, cultivated, and shipped, they are often cultivated in greenhouses or indoor pools where the temperature and other environments are stable. The color tone of the ornamental plants and the fish for ornamentation greatly affects the product quality.

[0006] For example, the color is a plant of the taro family native to South Africa, which comprises a long-stem flower extending from between leaves. In addition, the flowers have bracts (Buddha bracts) surrounding the inflorescence, and the flower color of these bracts is appreciated.

Such a color is, for example, for pot flowers, grown in a greenhouse such as a vinyl house, and shipped when two or three flowers have bloomed and put on the market. by the way,
If the color becomes high during the daytime during growing, it is necessary to reduce the temperature in the greenhouse such as a vinyl house by shielding the light. However, when such light shielding is performed, there is a problem that the flower color becomes unclear due to lack of sunlight, the commercial value thereof is significantly reduced, and the market value is lost.

[0008] Goldfish, Nishikigoi and the like have a thin and unclear body color when cultivated and cultivated in an indoor aquaculture pool, so they were transferred to an outdoor aquaculture pool, where they were cultivated for a while before being shipped. However, the movement of the cultured fish to the outside complicates the aquaculture work, and since the growing environment is not stable, there is a possibility that the growing state deteriorates and stable shipping cannot be performed.

Further, although the variety of ornamental plants and ornamental fish has been improved so as to have a desired color tone, there is a problem that such variety improvement requires a great deal of labor and time.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems associated with the prior art, and can impart desired color tone and color density to the ornamental plants and ornamental fish to be raised. It is an object of the present invention to provide a method for growing an ornamental plant and an ornamental fish that can stably ship an ornamental plant and an ornamental fish with high commercial value.

[0011]

SUMMARY OF THE INVENTION A method for growing an ornamental plant according to the present invention is
It is characterized in that an ornamental plant is cultivated while being irradiated with ultraviolet rays by an ultraviolet lamp, and the leaf color and / or flower color is adjusted.

Further, the method for raising an ornamental fish according to the present invention is characterized by raising the ornamental fish while irradiating ultraviolet rays with an ultraviolet lamp to adjust the body color. The present invention is particularly effective when growing these ornamental plants and ornamental fish in a room such as a greenhouse.

According to the present invention, since the plants for ornamental use and the fish for ornamental use are cultivated while irradiating the ultraviolet rays with the ultraviolet ray lamp, the flower color is caused by the shading during the day, the indoor cultivating or the lack of sunshine due to the bad weather. The adverse effects on leaf color and body color can be prevented significantly more effectively than when using visible light irradiation.

Further, in the present invention, the concentration of flower color, leaf color and body color of a fish body can be adjusted by adjusting the intensity of ultraviolet rays. By limiting, it is possible to cause a color change only in a desired portion in plants such as flowers and leaves.

[0015]

DETAILED DESCRIPTION OF THE INVENTION The method for raising an ornamental plant and an ornamental fish according to the present invention will be described more specifically with reference to the drawings.

FIG. 1 is a schematic diagram for explaining a method for growing an ornamental plant according to the present invention. As shown,
The method for growing an ornamental plant according to the present invention is a conventionally known cultivation / production method except that an ornamental plant, for example, color 2, roses 3, amaryllis 4, etc. is raised under irradiation of ultraviolet rays from an ultraviolet lamp 1. May be.

Therefore, the method of the present invention can be suitably applied to the cultivation of ornamental plants in a house, the cultivation in a greenhouse such as a vinyl house, and particularly commercial cultivation.
Further, the plant species to be applied is not particularly limited.

More specifically, the present invention provides a variety of flowers for viewing flowers such as the taro family such as color 2, the rose family such as rose 3 and the Amaryllidaceae plant such as Amaryllis 4, or the orchid family plant. It can be effectively applied to various plants. .
In addition, the same effect can be expected in plants that appreciate leaves such as begonia, caradium, hen head, moto, some orchids, sardine and Aoki.

Further, according to the present invention, it is possible to expect the color change, the sharpening or the high color density of the flower color and the leaf color peculiar to the plant species and varieties by the irradiation of the ultraviolet rays. It is desirable to appropriately select the irradiation dose of ultraviolet rays, the irradiation time (interval), and the irradiation time depending on the desired site of the plant, the shipping time, and the like.

For example, as shown in FIG. 1, in a plant such as color 2, rose 3, and amaryllis 4, which appreciates flowers, flower buds are formed and flowering starts from the time immediately before flowering ( By irradiating during the shipping period, it is possible to grow ornamental plants having a deep flower color and clear flowers, and ship them as cut flowers or potted flowers.

In the case of a plant whose leaves are to be appreciated, by irradiating it with ultraviolet rays for a certain period of time before shipment, ornamental plants having a desired leaf color can be grown and shipped as cut flowers or potted flowers. It is possible.

Of course, when raising at home, always
If you irradiate ultraviolet rays intermittently for a certain period of time, you can appreciate the stable flower and leaf colors. In addition, by partially covering the plant with ultraviolet rays, it is possible to give one plant a part having various color tones and shades of color. Therefore, for example, a single plant can be made to bloom a flower having a plurality of color tones and color densities.

The wavelength of the ultraviolet rays to be irradiated in the present invention may be selected according to the kind of the ornamental plant to be grown and the site where the color change is desired, and is not particularly limited.
Usually 200 nm to 400 nm, preferably 240 nm to
It has a wavelength of 350 nm, particularly preferably 250 to 300 nm.

The amount of ultraviolet rays applied to the ornamental plant is also appropriately selected so as not to adversely affect the plant and to cause a color change in a desired site. This is selected according to the condition of the plant to be cultivated. Can be easily achieved by adjusting the output of the ultraviolet lamp, the arrangement density and the arrangement height. The amount of ultraviolet rays can also be adjusted by providing a shielding plate or a filter on the ultraviolet lamp.

The time for irradiating ultraviolet rays in one day is not particularly limited, but considering the influence of ultraviolet rays on the human body, it is desirable to perform it at night when the human body is less likely to be exposed.

Next, a method for raising the ornamental fish according to the present invention will be described. FIG. 2 is a schematic diagram for explaining the method for raising an ornamental fish according to the present invention. As shown in the figure, in the present invention, the aquarium 10 is irradiated with ultraviolet rays by the ultraviolet lamp 11.
A conventionally well-known breeding method may be used except for breeding the ornamental fish, such as goldfish 12 and Nishikigoi 13.

Therefore, the method of the present invention can be suitably applied to the cultivation of ornamental fish in an aquarium in a house, the cultivation in a greenhouse aquaculture pool such as a vinyl house, and particularly to commercial aquaculture. The fish to be applied is not particularly limited.

Further, in the present invention, it is possible to expect the body color of the appreciation fish to become clear or to have a high color density by irradiation with ultraviolet rays. Therefore, depending on the type of the appreciation fish, the shipping time, etc., the irradiation dose and irradiation time of the ultraviolet rays ( It is desirable to appropriately select the interval) and the irradiation time.

For example, as shown in FIG. 2, a goldfish 12
When breeding Nishikigoi 13 in the indoor aquarium 10 for appreciation, a relatively low amount of ultraviolet rays is constantly or continuously radiated for an appropriate time to give the fish body a vivid body color. Can be granted.

When a large number of ornamental fish are cultivated on a commercial basis, the ornamental fish having a desired body color are raised by irradiating a certain amount of ultraviolet rays during a certain period before shipping. It is possible.

The wavelength of the ultraviolet rays irradiated in the present invention may be selected according to the type of the ornamental fish to be raised,
Although not particularly limited, it is usually 200 nm to 400 nm, preferably 240 nm to 350 nm, particularly preferably 25 nm.
It has a wavelength of 0 to 300 nm.

The amount of ultraviolet rays applied to the fish for appreciation is also appropriately selected so as not to adversely affect the fish body and to cause a color change in a desired portion. This is an ultraviolet lamp according to the condition of the fish to be bred. It is easily achieved by adjusting the output, the arrangement density, the arrangement height and the like. The amount of ultraviolet rays is
It is also possible to adjust the UV lamp by providing a shield plate or a filter.

The time of ultraviolet irradiation in one day is not particularly limited, but considering the effect of ultraviolet rays on the human body, it is desirable to perform the irradiation at night as long as it does not affect the growth of fish.

According to the method for cultivating color according to the present invention as described above, the shortage of sunlight due to shading during the day, impure weather, etc. is compensated by ultraviolet irradiation from an ultraviolet lamp. In comparison, it is possible to produce a color having a significantly bright flower color. In addition, even when performing temperature control in the greenhouse from spring to summer during light-shielding during greenhouse cultivation, the flower color is not affected, so the yield of colors from spring to summer is good,
It is possible to stably mass-produce high-quality plants.

Further, it is possible to produce a color having a flower color having a desired sharpness by appropriately changing the irradiation dose of ultraviolet rays, specifically, the output of an ultraviolet lamp and the irradiation height and irradiation time.

Although the present invention has been mainly described by exemplifying the case of cultivating and producing potted flower plants of upland cultivars, the present invention should not be construed as being limited thereto. Without, irradiate ultraviolet rays with an ultraviolet lamp at the time of growing,
It goes without saying that cultivation of potted plants of wetland cultivars, cut flowers of wetland cultivars and upland cultivars are also within the scope of the present invention.

[0037]

As described above, according to the present invention,
Since it was decided to cultivate plants and fish for appreciation while irradiating ultraviolet rays with an ultraviolet lamp, shading during the day,
The adverse effect on flower color, leaf color and body color due to lack of sunshine due to indoor cultivation or poor weather can be significantly effectively prevented as compared with the case of using visible light irradiation. Therefore, an ornamental plant having a desired flower color and leaf color and an ornamental fish having a desired body color can be continuously appreciated at home and the like, and if applied to commercial cultivation and breeding, these high-quality ornamental plants can be appreciated. It becomes possible to easily and stably supply plants and ornamental fish.

Further, in the present invention, the color tone and density of the flower color and leaf color of the plant body or the body color of the fish body can be freely adjusted by adjusting the intensity of ultraviolet rays. By limiting the irradiation position,
Since it is possible to change the color of plants such as flowers and leaves only in the desired parts, it is a plant and ornamental plant that has a flower color, leaf color or pattern, or body color that is as vivid and attractive as the natural world cannot expect. It is now possible to provide fish.

Hereinafter, the method for raising ornamental plants and ornamental fish according to the present invention will be described more specifically with reference to Examples.

[0040]

Example 1 Colored rhizomes were potted by a conventional method and grown until flower buds (buds) were formed at the tips of the long stems extending from the leaves to prepare colored adult plants.

Next, the colored adult plant 2 having buds is
Immediately before this bud opens, as shown in FIG.
When grown under a 15w ultraviolet lamp 1 arranged at a height of 00 mm for 3 days, a red (golden red) flower bloomed and the stem also turned red.

The irradiation time by the ultraviolet lamp 1 was 12 hours from 6:00 pm to 6:00 am per day. In addition, a colored adult plant having flower buds was similarly grown for 3 days except that it was not irradiated with ultraviolet rays at night to bloom.

After 3 days, the color of the flowering flower was compared and observed, and it was found that the color irradiated with ultraviolet rays had a deeper and clearer flower color.

[0044]

[Example 2] An adult plant of Amaryllis, which had been potted and cultivated until flower buds (buds) were formed, was prepared by a conventional method.

Next, an amaryllis adult plant 4 having buds
Immediately before the opening of the bud, as shown in FIG. 1, it was cultivated for 3 days under a 15w ultraviolet lamp 1 arranged at a height of about 1500 mm from the flower bud, and flowered.

The irradiation time by the ultraviolet lamp 1 was 12 hours from 6:00 pm to 6:00 am per day. In addition, an amaryllis adult plant body having flower buds was similarly grown for 3 days and allowed to flower, except that the UV irradiation was not performed at night.

Three days later, when the color of the flower that had bloomed was compared and observed, the flower color of amaryllis that had been irradiated with ultraviolet rays was red, whereas that of amaryllis that had not been irradiated with ultraviolet rays had a pale pink color.

Even in the amaryllis that has been irradiated with ultraviolet rays, the portions where the shadow of the irradiated ultraviolet rays is formed (the back side of the flower and the corresponding side surface of the stem) are similar to those of the color that is not irradiated with ultraviolet rays. Had a color.

[0049]

Example 3 A rose adult plant body was prepared by potting in the usual manner and growing up until a plurality of flower buds (buds) were formed.

Next, the rose adult plant body 2 having buds was separated from the buds by about 150, immediately before the buds opened, as shown in FIG.
It was grown under a 15w ultraviolet ray lamp 1 arranged at a height of 0 mm for 3 days, and at this time, one side of the plant was shielded so as not to be irradiated with ultraviolet rays, and the color of the flowering flower was observed.

The irradiation time by the ultraviolet lamp 1 was 12 hours from 6:00 pm to 6:00 am per day. As a result, bright and bright flowers were blooming on the side irradiated with ultraviolet rays, and pale and pale flowers were blooming on the side not irradiated with ultraviolet rays.

[0052]

Example 4 As shown in FIG. 2, water was introduced into a glass water tank 10 with an ultraviolet lamp 11 provided inside a room.

Then, the goldfish 2 and the scarlet carp 3 were released into the aquarium 10 and kept under irradiation of ultraviolet rays for several weeks. The ultraviolet lamp 1 had its irradiation dose adjusted by a filter. Also,
The irradiation time was 12 hours from 6 pm to 6 am in a day.

Goldfish 2 and scarlet carp 3 were bred for the same period except that no ultraviolet irradiation was performed at night. After the rearing, the body color of the goldfish and the scarlet carp were compared and observed, and it was found that the ornamental fish irradiated with ultraviolet light had a deeper and more vivid red-orange color.
