Description

Method of seminal propagation for Acer okamotoanum}

The present invention relates to a practical method of propagating Umbrella cypress, more specifically, by collecting seeds of the Umbrella cypress, insecticide with hydrogen gas and immersed in a Gibberellin solution, refrigerated, and then sterilizing with Toros hydrous immediately before sowing. Umbrella cultivating soybean seed is a method of breeding.

Cypress ( Acer mono Max.) is a deciduous tree belonging to the Maple family and grows at 100 ~ 1,800m above sea level and is distributed in Korea, Japan, China, and Manchuria. It is known to grow wild in the valley.

A country of native species is Acer mono ((Acer mono ), red hawthorn tree ( A. mono for. rubripes ), umbrella buckwheat tree ( A. okamotoanum ), mango rot tree ( A. truncatum ), long buckthorn tree ( A. mono for. dissectum), king of Acer mono (A. mono var. savatieri), Acer mono acid (A. mono var. horizontale), Tong Acer mono (A. mono for. connivens), hair Acer mono (A. mono var. ambiguum) Nine varieties and varieties are known to grow. Among them, Umbrella is a species native to Ulleungdo.

Umbrella is a representative species of sap collected from the end of February to the middle of March, and is used in the private sector as a drinking water. Trees, beech trees, birch, birch, and ash trees, and more than 90% of the total sap collected is collected from the buckthorn.

In addition to moisture, Umbrella cypress sap is rich in sugars and minerals such as glucose, sucrose and fructose, and the minerals are mostly calcium and potassium, some of fluorine, manganese and iron, and other amino acids, vitamins A and C. It is 30-40 times more calcium and 10-20 times higher potassium than normal drinking water.

In oriental medicine, patients with gastrointestinal disease, lung disease, neuralgia and arthritis are drunk with water, the leaves are hemostatic agents, the roots and roots are used for the treatment of joint pain and fractures. Ingestion of large amounts does not result in stomach upset, so you can use it as a substitute for drinking water.

In addition, because of its rapid growth, it can be used for afforestation in the third year of life. It is also used for landscaping, and its value is gradually increasing because it is used for structural or furniture materials because wood is dense and hard and does not crack well. There is a limited number of indigenous populations, and their preservation and afforestation are urgently needed.

However, the most common method of propagation of native plants is harvesting seeds and direct seeding on sowing. Most of the seedlings have a short germination period and germinate evenly at once, so that the seedling growth is even. Although the yield of seedlings can be increased, Umbrella is not well germinated due to the failure of sowing time and seed treatment due to lack of growth characteristics, proper seed treatment, and cultivation management methods. The situation is experiencing a lot of difficulties.

Umbrella, which is a useful forest resource as described above, is mostly grown naturally in its natural state, so its quantity and distribution area are limited compared to other species, and the health of the tree is deteriorated by indiscriminate sap collection.

In order to improve this, there are attempts to cultivate and spread Umbrella cypress seedlings in some farmhouses, but there is a problem that the ratio of seedlings produced is lower than that of sowing because no efficient cultivation method is established.

The problem to be solved by the present invention is to provide an appropriate treatment method and seedling method of Umbrella buckthorn seed which can increase the yield rate of Umbrella buckthorn tree, which requires preservation and afforestation, and produce healthy seedlings.

In order to achieve the above object, the present invention, the step of harvesting the seeds of the Umbrella Bilberry around October; Insecting the collected seeds with hydrogen gas for 20 to 30 hours; Immersing the insecticidal seeds in a 45-55 ppm gibberellin solution for 20-30 hours, then scooping them up and refrigerated for storage; Disinfecting the gibberellin-treated refrigerated seeds with 50% Toros Hydration just before sowing; October and the following year, after the rotary operation stops the seeding planting and to make a picket, and then scavenging the disinfected seeds of the powder; Covering the seeded patter with rice straw; In early March, just before seed germination, a stepping rod was installed on the toe, a vinyl tunnel was covered with vinyl, and a heat insulating cover was sealed thereon; Walking the insulation cover and the vinyl in mid-April to cover the light shielding film on the shaft; And in mid-May to remove the shade and the rafters to provide a Umbrella buckthorn live breeding method comprising the step of obtaining seedlings.

At this time, it is preferable that the amount of toros hydration used in the step of disinfecting powder is 10-15 g of toros hydration per liter of seed.

In addition, it is preferable that the seeding time of the step of swelling is October to November.

In addition, the dot method of the step of the digging step is to make a hole or soak the seed to the seedlings and then dug the seeds, evenly covering the sand or raw soil 1 to 2 cm thick and then press lightly on the toads It is desirable to give.

In addition, in the sealing step, it is preferable to roll up both edges of the vinyl covered with the sash and the heat cover during the day and to cover at night.

In addition, after the step of obtaining the umbrella tree seedling seedlings, when the seedlings are 1.5 ~ 2m it is preferable to remove the side branches and twigs of the seedlings to form one trunk and then transplanted.

Actual growth method of Umbrella buckthorn tree according to the present invention can increase the seeding rate of the Umbrella buckthorn tree having difficulty in breeding because the effective seedling cultivation method is not established. Can contribute to

Hereinafter, the present invention will be described in detail.

First, the seeds of the Umbrella gooseberry are harvested. Usually, the seeds are harvested in October, so the seeds are collected.

Next, the collected seeds are pesticide using hydrogen gas (PH ₃ ) for 20 to 30 hours.

Hydrogen fluoride gas is a fumigation agent widely used for the control of storage pests. It is excellent in penetration and diffusion due to its high vapor pressure, but due to toxicity, care should be taken in handling and using it.

Insecticide method can be safely insecticide because the phosphate is reacted with moisture in the air to slowly generate hydrogen fluoride gas when the tablet containing the collected Umbrella seed and phosphide (aluminium phosphide) in a closed space.

However, since the phosphide has a disadvantage in that the decomposition rate is slow and it takes a long time to kill pests, a machine for quickly releasing gas such as a crushing blower, liquefied hydrogen phosphide, hydrogen phosphide / carbon dioxide mixed gas, etc. has been recently developed and used. .

When the insecticide is completed, it is immersed in a growth hormone hormone 45-55ppm gibberellin solution for 20-30 hours, then pulled out and stored in the refrigerator (1-5 ℃) until sowing.

Gibberellin is a type of hormone that promotes renal growth, seed germination, flowering, increase fruiting, and fruit growth. Gibberellin diffuses into the cell to produce alpha-amylase.

As the seed germinates, the young roots and stems of the embryos begin to grow, and the stored nutrients stored in the form of starch, lipids or proteins in the embryo or cotyledons are decomposed, and the degraded nutrients grow from the stored tissue cells. The nutrients of the storage nutrient are lipases, proteases, ribonucleases, and the like.

The produced alpha-amylase is an enzyme that catalyzes the hydrolysis and serves to promote the growth of Umbrella as the germination and growth so that the seedling can grow healthy and fast.

The hydrogen phosphate gas and gibberellin treatment is preferably carried out immediately after the seeding, because the seed's vitality decreases as the seeding and over time increases the likelihood that the gibberellin treatment will rather decay the seed.

Next, the gibberellin-treated refrigerated Umbrella Biloba seeds are sterilized immediately before planting.

For seed sterilization, it is preferable to disinfect the seeds of Umbrella with a toros hydrous with a tolclofos-methyl content of 50%, and about 10-15 g of toros hydrous per liter of seeds.

The toros hydration is strong sterilization but less human toxicity can be used safely, strong soil adsorption power is less mobility and long-lasting effect is effective in the control of harmful bacteria when sowing seeds can increase the survival rate of germinated seeds.

After the preparation of the seed to be sown is completed, the seedlings are prepared after making a roundabout operation, and then the seeds are prepared and the seeds are sown.The sowing time is from October to the following year. Autumn sowing in month is more desirable.

The pointing method is to make a hole or to dig a seed by digging the even toads with a seeding long, and then cover the sand or raw soil uniformly to a thickness of 1 ~ 2㎝ and then lightly press the toads with a plank or the like.

When the cover thickness is less than 1 cm, seeds are lost or sensitive to the influence of water shortage or outdoor temperature, and when the cover thickness is more than 2 cm, the diffusion of oxygen from the surface to the ground where the seeds are not so tends to germinate, which is undesirable. not.

After sowing, cover the toad with rice straw and cover it with a shading shield so that rice straw is not lost.

In the case of facility cultivation other than open cultivation, it is not necessary to install a light shield.

The seeded Umbrella seedlings enter the germination preparatory stage in the fields until spring, when spring begins and the frozen ground thaws, which begins to germinate in early March. Insert a vinyl cover to make a vinyl tunnel and cover it with a heat insulating cover.

If the germination is late due to impure climate or soil conditions, or at the same time it is not possible to germinate evenly, the edges of both the vinyl and the insulation cover covered by the sill are rolled up during the day when the temperature rises so that the outside air is ventilated. It is advisable to keep it warm at night when it comes down.

The dormant seeds are extremely respiratory, but the germinating seeds are more respiratory and the oxygen demand increases, so that the seeds with poor germination are well germinated and germinated evenly by aeration as above. Be sure to

In mid-April, we walk on the insulation cover and vinyl, cover the shade with the shade, and then, in mid-May, walk through the shade, remove the rod, and then raise it to obtain Umbrella.

After that, the umbrella seedling seedlings are cultivated according to the general tree cultivation method by transplanting the seedlings to the general public or planting them at a suitable plant density, and the seedlings at the time of transplantation are suitable for 1.5-2 m. It grows faster and has an advantage in competition with the surrounding ground plants, which can increase survival rates.

In addition, in order to obtain a lot of high-quality sap, it is preferable to remove all the side branches and twigs in the upright trunk with pruning shears so that only one trunk is formed.

Hereinafter, the present invention will be described in more detail based on the following examples, comparative examples and test examples.

It is to be understood, however, that the invention is not to be construed as limited to the embodiments set forth herein, but is capable of modifications and equivalents within the spirit and scope of the invention. Will be apparent to those skilled in the art to which the present invention pertains.

≪ Example 1 >

In October, seeds of the umbrella tree were harvested and immediately placed in a closed space with tablets containing phosphide for pesticide.

The seed of which insecticidal was completed was immediately immersed in 50 ppm gibberellin solution for 24 hours and then removed and stored at 3 ° C. for refrigeration.

In early November, the refrigerated seeds were disinfected with 50% Toros Hydration (Resotex, Danong, Korea), and the mixing ratio was added 200 g of Toros Hydration per 15 liters of seeds.

Next, after the rotary seeding site of the open field to make a toad, and then picked with a ginseng seeding planting long hole to make holes, and then sterilized the seeds of the powder (see Fig. 1).

The hole was covered with 1.5 cm thick using a raw clay, and then lightly pressed the torso with a plank, and then covered with rice straw (see FIG. 2), and covered with a light shielding film to prevent rice straw from flying away.

In early March, just before the germination of the Umbrella seeds, they walked the shade screen and plugged the rods, and then covered the vinyl with vinyl to make a vinyl tunnel, and then covered the insulation cover to keep the seed seeded (see Fig. 3).

After walking the insulation cover and vinyl in mid-April and covering the shade with a light shield (see FIG. 4), the shading membrane was rolled out in mid-May to obtain young seedlings of the Umbrella.

After seeding (see Fig. 6) when the seedling of the Umbrella gooseberry tree was about 1.5m (see Fig. 7), all the branches were removed, leaving only one upright tree, and then transplanted at a plant density of 800 plants per ha in the Yasan Valley.

<Example 2>

In Example 1, except that the seed disinfection and sowing time was carried out at the end of January the following year, Umbrella locust tree was grown in the same manner as in Example 1.

<Example 3>

In Example 1, except that the edges of the vinyl and the heat cover are lifted about 10 cm from the ground during the day and down to contact the ground at night until the vinyl and the heat cover are removed from the slide. In the same manner as in Example 1 was cultivated Umbrella.

Comparative Example 1

In Example 1, the Umbrella was grown in the same manner as in Example 1 except that the collected seeds were treated immediately with Gibberellin solution and then refrigerated without insecticide treatment with hydrogen gas.

Comparative Example 2

In Example 1, the Umbrella was grown in the same manner as in Example 1, except that the insecticide-completed seed was immediately refrigerated without Gibberellin treatment.

Comparative Example 3

In Example 1, the refrigerated seeds were cultivated in the same manner as in Example 1 except that the seed stored in refrigeration was sown in early November without disinfection of powder with toros hydrate.

<Test Example>

Germination, soy sauce, and leaf number of the Umbrella cypress seedlings obtained in the above Examples and Comparative Examples were measured and shown in Table 1 below.

Germination measurement was calculated based on the number of sprouted holes based on the total number of holes sown at the time of walking the light shielding film in mid-May.

Soy sauce is a value obtained by randomly selecting 10 samples for each Example and Comparative Example about 3 months after seedling, and measuring and averaging the distance from the longest ground to the top end.

About three months after seedling, the number of leaves is a value which randomly selected five samples for each Example and a comparative example, counted the number of leaves, and averaged them.

Results of Germination, Soy Sauce, and Leaf Count of Umbrella Seedling Seedlings unit Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Germination % 86.8 83.2 91.6 75.1 68.1 65.4 Soy sauce m 1.72 1.54 1.76 1.53 1.39 1.60 Leaf number dog 96 78 104 74 55 69

As a result of Table 1, it can be seen that the Example is a better breeding method of seedlings than the Comparative Example as a whole, in particular, while the method of Example 3, which carried out the early germination, showed the best results, the gibberellin treatment compared The seedlings of Example 2 showed the worst results.

As described above, the actual growth method of the Umbrella gooseberry tree of the present invention increases the yield rate of the Umbrella gooseberry seed, and provides a method for healthy growth of germinated seedlings, thereby establishing an efficient breeding method of the Umbrella gooseberry tree. Therefore, it can be usefully used for production farms that are having difficulty breeding.
