Description

Production method for White Rhododendron mucronulatum seedling}

The present invention relates to a method for producing white rhododendron seedlings.

Azalea ( Rhododendron mucronulatum ) is a deciduous shrub to the Azalea family of the dicotyledonous plant and grows in Korea, Japan, China and Mongolia.

Rhododendrons are also known as true flowers or head and fairy tale, grow in sunny places in the mountains, and are shrubs that are 2-3m high.

Many branches diverge from the top of the stem of rhododendron. The twig is light brown and has scales. Leaves are alternate, long oval lanceolate or upside down lanceolate, 4-7cm long, narrow at both ends, and flat. The leaf surface has some scale pieces, the back side has dense scale pieces, hairless, and petiole is 6 ~ 10mm long.

Flowers bloom before leaves between March and April, with two to five flowers at the end of each branch. Sometimes leaves come first and flowers bloom. Funnel-shaped flowers are about 3 to 4.5 centimeters in diameter, and the color is dark purple or light red, usually pink. The azalea's petals have hairs on the outside, stamens are ten, and the style is slightly longer and slightly curved upwards than the stamens. Flowers are made in early spring to make flowers or soak azaleas. In oriental medicine, flowers are used as a medicine called Yeongsanhong (迎 山 紅), which is effective for headaches caused by seawater, bronchitis, and cold, and has a diuretic effect. The flower resembles azaleas a lot, but the leaves are pointed ovals unlike azaleas and have a glossy surface.

Fruits are capsules, cylindrical, 2cm long, with a pistil left at the end. Seeds of rhododendron bloom in late September.

Roots have hairy roots, and because they do not go deep into the ground, they grow well even if the ground is shallow, so they have a tendency to like damp ground.

Rhododendrons are slightly different in appearance depending on where they grow, so they are named according to the region.

Small branches and leaves with hairs are called hairy azaleas (var. Ciliatum) and are commonly grown on the seashore and in high mountains. White flowers of hairy rhododendrons are called white azaleas (for. Alba) and are sometimes seen near the shore. A round or broad oval shaped leaf is called azalea (var. Latifolium). Among the ones growing near the beach, the leaves are glossy and the mantis-like projections on both sides are called var. Maritimum, and the fruit is thinner and longer is called var. Taquetii. It is short in length, has small flowers, and has five stamens. It is called Jeju Azalea (R.saisiuense) and grows near the summit of Halla Mountain. On the other hand, rare species include white azaleas (for. Albiflorum).

Rhododendrons also grow in barren lands, especially because they like acidic soils, so azaleas grow well, indicating that the land is desolate and acidified. When deciduous deciduous forests are destroyed in the mountains, pine growth is prominent, and when these pine forests are destroyed by the acidification of the soil, rhododendrons grow.

Azaleas bloom only when winter is cold, so if you grow azaleas at home, you need to cool them down to -10 ℃ to 0 ℃ during the winter.

Rhododendrons cannot withstand the warmth of their nature, so they do not grow in the hot sunlight of the summer, and grow well on the ground where there are stones on the surface of the ground or where large trees make shade. In other words, because azaleas have shallow roots in the soil, moisture dries quickly in warm places, making it difficult to survive. This is why azaleas are more prominent in the colder north than in the south.

Azaleas are cultivated mainly for ornamental purposes because of their beautiful flowers.

The present invention relates to the production of seedlings of white azaleas, a rare species of white flowers among the above mentioned azaleas.

As a related art of the present invention, there is a method of breeding azalea and yellow azaleas in Korean Patent Application No. 1996-35485. However, this prior art is about the cutting formula of yellow azaleas and the technical configuration is different from the present invention.

An object of the present invention is to provide a method of producing seedling seedlings of white azaleas, which are a rare species of azaleas, which are widely used for ornamental purposes.

Another object of the present invention is to provide a method for producing white rhododendron seedlings, which are rare species, and to improve the spread of white rhododendrons, which are endangered to native plants due to increased imports of azalea seedling producers and the provision of rare white rhododendron seedlings.

1 is a process of producing white rhododendron seedlings of the present invention.

The method of producing white rhododendron seedlings of the present invention comprises the steps of sowing white rhododendron seeds on a seedling comprising left agar and moss, germinating seeds on the seedling to produce young seedlings, and decorating the young seedlings; And selecting white rhododendron seedlings upon flowering of the first flowers after planting, and formulating and trimming the selected white rhododendron seedlings.

In the present invention, in order to improve the germination rate of the seed of the white rhododendron, it is preferable to soak for 5 to 6 days in natural water at room temperature, more preferably 25 ± 2 ℃ temperature, and then sowing on seedlings. In general, the seeds are often in a dry state, and because the seed is hard to absorb the moisture required for germination immediately, the white azalea seeds in the present invention are soaked in water at room temperature for 5-6 days before sowing and then sowing. It is good.

In the present invention, the white rhododendron seeds are sown in a nursery box containing a subsoil: masato: ocher in a seeding top soil and moss in a volume ratio of 1: 1. The sowing soil improves the germination rate of the seed, and first mixes the soil and the side leaves (계속 葉) in order to maintain the continued intelligence (地力), and coats the moss on the soil mixed with the side leaves for the moisture moisturizing power of the seeds. At this time, the moss is coated with 0.3 ~ 0.5 ㎝ thickness sterilized for the prevention of a jar disease to maintain the moisture moisturizing power of the seed.

On the other hand, in order to improve the germination rate and maintain the strength of the seed (intelligent), an intelligence enhancer such as compost or fertilizer can be used instead of the side lobe. In the present invention, since the seeding soil consisting of the foliar and the soil is formed in various amounts, the seeding soil in the present invention is suitable for improving the germination rate of the seed. It is recommended to use a volume ratio of 1: 1. The soil used for sowing soil in the present invention can be used as long as it is commonly used for cultivation of flowers or seedlings. As an example of such soil, in the present invention, any one selected from Masato, loess, loam, humus, sandy loam, clay, or two or more is selected. Mixed soils can be used at the same mixing ratio.

On the other hand, white azaleas grow well in an acidic environment as mentioned in the "Technology to which the invention pertains and the prior art of the field", so that the seeding soil of the first seedlings remains neutral, and about 30 days after the white azalea seeds germinate. Afterwards, an acidity (pH) regulator (sulfuric acid) may be added during watering so that the acidity (pH) of the sown soil is 5-6. In this case, when the pH of the seeded soil is less than 5 or the pH is more than 6, the growth of the white rhododendron is not good, so the pH of the seeded soil is preferably maintained in the above-described range.

In the present invention, the white rhododendron seeds sown on the seedlings are covered with a coating to prevent the hair growth and at the same time to maintain a temperature of 22 to 25 ℃, humidity conditions of 75 to 85% to germinate white azaleas. The cover used to prevent the drying of soil can be easily obtained from the surrounding area, and it is possible to use inexpensive papers such as newspapers, corrugated paper, and Korean paper, and straws and glass. When white azaleas germinate, they maintain the above temperature and humidity conditions to grow white azalea individuals. Germinated and multiplied white rhododendron under various temperature and humidity conditions, so it is preferable for germination and growth of white rhododendron seeds under the above temperature and humidity conditions. Germinate and multiply white rhododendrons under conditions of humidity. Germinated white rhododendrons should block 50% of their direct contact with light, or they can grow white azaleas under mild temperature and humidity. This is because, as mentioned above, the azalea roots are shallow in the soil, so when exposed to strong direct sunlight, the moisture contained in the roots may evaporate and the growth of the white azalea may be delayed.

Proliferated white rhododendron individuals use known methods to prevent pests. For example, the soil mixed with fungicides may be added to the sowing soil to prevent diseases and pests of white azaleas or to directly apply pest preventing agents to white azaleas. This pest prevention work should be carried out continuously in order to prevent disease as well as the development of pests.

In the later germination, white azalea individuals grow to 4 to 5 leaves, 2 to 3 cm in height, and carry out primary decoration at intervals of 3 cm × 3 cm for decoration. At this time, the temporary soil to which white rhododendrons are to be transferred by decorating may use the sowing soil mentioned above. After the decoration, when the white rhododendron grows to a size of 4 cm to 5 cm, the second decoration is performed at intervals of 9 cm × 9 cm. In the present invention, such planting should be carried out with a wide interval according to the size of spring seedlings every year from the first planting to the fourth to fifth year of flowering of the first flower.

When the white rhododendron blooms after planting, the white rhododendron individuals are screened from among them and settled on the soil prepared in advance. At this time, when the white rhododendrons are settled, the soil may use the sowing soil mentioned above. Formal white azaleas are trimmed so that the white azaleas harmonize with the surrounding environment by cutting off only the necessary branches so that the tree does not disperse. On the other hand, unnecessary branches that can occur as white rhododendrons grow continue to stop and refine the tree.

Hereinafter, the present invention will be described by the following examples. However, these are only examples of the present invention, and the scope of the present invention is not limited thereto.

<Example 1>

White rhododendron seedling production process diagram of the present invention produced a white rhododendron seedling as shown in FIG.

White rhododendron seeds (obtained from: White rhododendron farmers (currently self-harvested), hereinafter referred to as "seeds") are collected and stored at room temperature in accordance with the ripening time of the seeds from the white rhododendron parameters. It was immersed for about 5 to 6 days in water at 25 ℃ temperature before sowing.

Apart from the preparation of seeds, seedlings were prepared containing seeded soils having a volume ratio of 1: 1 in the side lobe: mixed soil (masato + ocher). First, the side layers were mixed evenly in the soil and moss was coated about 0.5cm on top of the mixed soil. In the above, the soil used was a mixture of ocher and masato 50:50.

Seeds prepared in advance by soaking on seedlings using the above-mentioned sowing soil were mixed with sand and sown in a box of 30 cm × 60 cm. In addition to the sowing of seeds, the seeds were sown with a newspaper to prevent the drying of the soil, and the seeds were germinated by maintaining a temperature of 22 ° C. and a humidity of 75%. When the seeds germinated, the germination was managed by adding an acidity regulator so that the sowing soil became acidic with a pH of 5.5 while maintaining the above temperature and humidity conditions.

Afterwards, the germinated bodies grew to 4-5 sheets of leaf length 2-3 cm, and the temporary soil was planted 3 cm × 3 cm. After fermentation, the germination was continued to grow, and if it grew larger, the second fertilization was performed in the following spring (in April). At this time, the decorative soil was used as the sowing soil. Then, such decorating was carried out three to four times a year from the first decor to the fifth year of flowering.

Four years after the first planting, the azalea germination bloomed the flowers, of which 30 white azaleas with white flowers were selected and planted in the soil prepared in advance. At this time, the soil used for planting white rhododendrons was used sowing soil prepared by the same method used for sowing white azalea seeds. The white rhododendrons after the formalization were stopped and trimmed to produce 30 white azalea seedlings.

<Example 2>

Side lobe: Example 1 except that the soil (mixed with masato and ocher 50:50) is used sowing soil consisting of a volume ratio of 1: 1 and the seedlings are maintained at a temperature of 23.5 ° C. and a humidity of 80%. 30 white rhododendron seedlings were screened using the same method as in.

<Example 3>

Side lobe: Example 1 except that the soil (mixing clay and loam 50:50) using the soil in a volume ratio of 1: 1 and maintaining the seedlings at a temperature of 25 ℃, humidity of 85% Using the same method, 30 white azalea seedlings were selected and obtained.

The present invention can be widely used in azaleas widely used for ornamental purposes by providing a method of producing seedlings of azaleas, which are rare species of white flowers.

On the other hand, the present invention can provide a rare white azalea seedling production method to increase the income of the rhododendron seedling producer and provide more rare white azalea flowers for ornamentals.
