Description

Birch plant and its cultivation method

The present invention relates to a technique for producing plants of very high value for ornamental or educational use by whitening some or all of the leaves and stems of plants by treating and nurturing the seeds or growing plants with specific drugs. In particular, the present invention is commonly seen around us, and is easily treated to plants or seeds that are commonly cultivated and distributed in a very short time. It is about the technique to cultivate a beautiful plant and the use of it

Along with the acceleration of farming and the aging of rural workforce, the preference for growing high-income special crops is becoming prominent. Since flowers play an important role in the emotional life of human beings, they are becoming high-income crops due to the improvement of cultural level and the steadily increasing production and consumption. Therefore, the flower cultivation farmers are steadily introducing varieties that are more commercially viable, stable in production, and easy to ship, and at the same time develop cultivation techniques.

Since human desires are so diverse that it is difficult to advocate them, we want flowers that are newer and more beautiful and can last for a long time. Therefore, breeding and genetic manipulation are used to improve varieties to produce and supply them. In addition, they have developed technology to maintain beauty for a long time after harvest.

However, the development of new varieties by breeding or genetic manipulation techniques requires a lot of resources, time and effort, and is therefore only possible in specialized laboratories.

The inventors of the present invention have a special beauty compared to the ornamental plants commonly seen in the surroundings, and while trying to develop a flower that is easy to cultivate and free to produce and ship, a special substance has a specific physiological effect on the plant. I came into contact with a research paper that said it could represent a completely different color from the original color, and, while steadily researching it, I came to the conviction that the results could be used for the production of educational or ornamental plants. Therefore, after many researches using many special materials, plants and plant seeds, the production technology of the whitening plant system using whitening induction materials was completed.

Plants germinate and grow into seedlings, using the nutrients stored in the seeds as energy sources and synthetic raw materials to create structures that can grow independently in the environment. During this process, chloroplasts are produced and the plant becomes green, and these chloroplasts make photosynthesis using light, moisture and carbon dioxide. As a result of this photosynthesis, plants can grow and reproduce.

However, these chloroplasts may be inhibited by various substances or the chlorophyll produced may be destroyed. If the chlorophyll content in the stem or leaves is significantly reduced by the treatment of the drug, the plant does not appear green but becomes partially magnetized or whitened. The bleached or magnetized part of the plant may be partially produced and recorded over time with chloroplasts, but if it cannot be recovered, the nutrients cannot self-synthesize and will remain whitened for a while and then dry out. Therefore, almost no chlorophyll is white or purple, which is another beauty not seen in flowers.

Bleaching induced by the treatment of substances mainly occurs only in newly growing tissues. Thus, when treated with seeds, it is possible to whiten the whole plant. However, when the sprouts of the growing plant are treated, only whitened leaves grow when the concentration of the treated substance is high, and when the concentration of the treated substance is low, only one or two leaves are bleached, and the subsequent leaves become green leaves. Therefore, depending on the concentration of the substances to be treated in the plant, it is possible to produce beautiful plants in which whitened and green leaves are mixed.

Bleaching of plants induced by certain substances is possible in all plants. Woody, herbaceous, dicotyledonous and monocotyledonous plants can all easily induce whitening.

Whitening leaves are wilted and dead after a long time, so they are not suitable for long-term cultivation, but they are long for freshness and are suitable for ornamental use. It is also possible to design the plant because it can induce whitening at the desired site. Seeds treated with material and untreated seeds can be planted together in one pot to create pots in which both green and white plants grow together. On the other hand, these materials are also valuable for educational use. In other words, unlike green plants, whitening plants are not able to photosynthesize, so they cannot produce their own nutrients. Therefore, after a certain period of time, green plants grow normally, but white plants die. Therefore, it is possible not only to visually educate the plant physiology of photosynthesis by directly growing birches and green plants, but also to be useful for making the skin feel the importance of green in terms of environmental protection.

It is an object of the present invention to provide a whitening or magnetized plant of high educational and ornamental value produced using plants, plant seeds, plant tubers and whitening inducers.

It is another object of the present invention to provide a technology for producing fully whitened plants or partially whitened or magnetized beautiful plants by treating and cultivating whitening derivatives on plants, plant seeds and plant tubers.

Hereinafter, the present invention will be described in detail.

In the present invention, a substance used to induce whitening in plants is Fluridone (Fluridone, 1-methyl-3-phenyl-5- (α, α, α-trifluoro-m-tolyl) -4-pyridone) ), Norflurazone (Norflurazone, 4-chloro-5-methylamino-2- (α, α, α-trifluoro-m-tolyl) pyridazin-3 (2H) -one), metflurazon , 4-chloro-5- (dimethylamino) -2- (α, α, α-trifluoro-m-tolyl) pyridazin-3 (2H) -one), clomazone, 2- (2 Chlorobenzyl) -4,4-dimethyl-1,2-oxazolidin-3-one), Flurtamone (R, S) -5-methylamino-2-phenyl-4- (a, α, α-trifluoro-m-tolyl) furan-3 (2H) -one), Diflufenican, 2 ′, 4′-difluoro-2- (α, α, α-trifluoro Rho-m-tolyloxy) nicotinanilide), K-503 (2,3-dicyano-5- (3-chlorophenyl) -6-n-propylaminopyrazine), sulcotrione, 2- (2 -Chloro-4-methylbenzoyl) -1,3-cyclohexanedione), Difunone, EMD-IT 5914, 5-dimethyl-ami -Methylene-2-oxo-4-phenyl-2,5-dihydrofurancarbonitrile), Fluorochloridone, 3-chloro-4-chloromethyl-1- (3-trifluoromethylphenyl) -pi Ralidin-2-one), Dichlormate (3,4-dichlorobenzyl N-methyl-carbamate), Methoxyphenone (3,3'-dimethyl-4-methoxybenzophenone), Hal Haloxydine (3,5-dichloro-2,6-difluoro-4-hydroxypyridine), WL-110547 (1- (3-trifluoromethylphenyl) -5-phenoxy-1,2, 3,4-tetrazol). Some of the whitening substances listed above are sold as commodities abroad, with pluridone as 'Sonar', norflurazon as 'Evital, Solicam, Zorial', clomazone as 'Command', and defflu Pennycan is available under the trade name 'Javelin'. Whitening derivatives that can be used in the present invention are not limited to those listed above, but are applicable to any chlorophyll biosynthesis of plants to inhibit the formation of chlorophyll or to promote chlorophyll destruction through any mechanism. can do. In addition, these whitening materials may be used by mixing two or more kinds.

In order to induce bleaching on plants, an aqueous solution containing bleach-derived substances can be treated directly on plant seeds or plants, or surface treatment or irrigation treatment on soils in which plant seeds or plants are planted, and granular products can be placed on soil. It can also be processed. Commercially available electrodeposition agents may be mixed to ensure that the whitening derivatives are well adhered to plants or seeds.

Most plants in nature can be targeted to cultivate white or purple plants by inducing whitening. Grains such as, for example, corn, sorghum, rice, barley, wheat; Vegetables such as peppers, sunflowers, potatoes, sweet potatoes, cucumbers and buttercups; Royal valleys, umbrella gardens, grasses, blood, reeds, dapsali, weeds such as pig potatoes, woody plants such as roses and willows can be used to cultivate white flowers for almost all plants, and can be used for ornamental or educational purposes. .

The plant organs usable for induction of whitening may use seeds or tubers themselves, or the whole plant or partly cut off individuals in growth. For example, corn seed is buried with whitening inducer (powder treatment), or corn seed is soaked in whitening induction for a certain period of time, and then sown in soil to germinate and grow, resulting in whitening-inducing plants. Sowing of corn seeds in the soil and treatment of the whitening inducer directly in the soil also induces whitening as the corn germinates and grows. In addition, when soybean seed that has not been treated with whitening inducer is sown in the soil and grown for two weeks or more, the whitening induction is applied to the vegetable system by spraying the whitening inducer with an aqueous solution or treated with soil. The newly emerged leaves are induction of whitening, and green and whitening leaves coexist in one plant.

Whitening inducers can exhibit various phenomena on growing plants depending on the amount used. In other words, if a large amount of plant seeds, tubers, plants and soil treatment is easily induced whitening, but the plants do not grow properly and die in a short time. When the proper amount is treated, the seeds germinate or the plants grow and whiten, and in some plants such as corn, the plants show whitening and magnetization at the same time, thereby obtaining a beautiful plant. Treating a small amount of whitening inducer leaves white leaves followed by green leaves due to whitening induction, followed by green leaves, or parts of the leaves are white but partly green.

In the process of inducing bleaching of plants, it is essential to be exposed to light such as sunlight or illumination light. After the whitening induction material is treated, the whitening plant begins to be exposed to light. The higher the intensity of light, the faster the whitening induction rate. However, the whitening leaves dry faster if the light is continuously radiated. The task of exposing to light as it dies is sufficient for a period of time to induce whitening after the treatment of the agent. The intensity of light to induce whitening can be more than 200 lux, and the length of time required for induction of whitening is slightly dependent on the amount of whitening inducing substance, the type and growth of plants, the treatment method and treatment area of the drug, and the intensity of light. Although it is different, it is about 2 to 5 days in normal sunlight conditions, so no special equipment or environment is needed.

Plants made by induction of whitening can be used for ornamental or educational purposes as they are planted in hydroponic fluid or soil, and can also be used for flower arrangement in cut state by cutting out appropriate parts such as the bottom of the plant. When planting seeds and untreated seeds treated with an appropriate amount of whitening derivatives in one pollen together, a pollen in which both green and white plants coexist in one pollen can be obtained. Putting seeds such as rice seed or blood treated with whitening-derived substances in hydroponic cultivation pots, or adding small amount of buttercup roots to be discarded after trimming the stems, whitening is induced to make white plants easily.

Treating seeds with whitening materials, drying them and storing them at low temperature is very convenient because they can be used within two years without significant reduction in whitening induction activity or germination rate. In addition, even when mixed with well-dried soil and seedlings treated with bleach-derived materials, and stored at low temperature, the bleach is easily induced only by pouring water when used within 2 years without significant reduction of bleaching activity or germination rate. can do.

In order to grow cultivated plants by hydroponic cultivation, it is possible to store them for more than two years by putting the medicine in a container such as a plastic cup and sealing it. Add water and put tubers, such as onions, to be hydroponically grown, and then cultivate the whitened plants.

As described below, a technology for producing a plant having white or purple added thereto is described as an example.
