The present invention can be afforested at 400m above sea level, which is a part of timber resources, which is one of the important resources in daily life, and it is very economical, and it is possible to efficiently utilize national land, especially mountains. It relates to a pot and a tooth nursery method.

Paulownia has traditionally been used only as a material for musical instruments and furniture, but until now it has been used for many purposes such as packaging materials for export goods, various interior materials for building, plywood, furniture, etc. In consideration of this, the inventors studied the method and growth process of paulownia tree, which is a fast growing tree growing from 70 to 200 or more in 5-10 years. Relying only on conventional theories, it was recognized that failure rates were high.

As a conventional method investigated by the present inventors, the seedlings were grown to seedlings or roots of seedlings. The former was capable of seed sowing only in early April, and seedlings were transplanted from mid-June to early July. As a result, the seedlings were excavated and planted in a mountain or planted area. The latter cuts the length of the paulownia root about 15-20cm, planted it in the field from mid-March to early April, and then grew until autumn. This method is used to excavate and plant the paulownia seedlings produced by the former and latter methods over a long period of time, so that the roots are rotted due to the scars from the excavation of the seedlings and planted only from the end of March to April of the following year. It was possible to remove or deny or leave only one strong one out of the root malaria in the root of the roots after 1-3 years of planting. Oh (萌芽) hayeoteotda pruning and the like.

As a result, the main roots or entourage of seedlings are cut or injured in the process of making and chartering by the former and latter methods. Growth is normal, but after about 4-6 years, the root disease caused by wounds or decay of the short-term muscles causes early senescence, and the growth is stopped or slowed down, and finally the roots of the paulownia tree decay from the cut roots. The outer skin part is changed to black or brown, causing decay and death.

In particular, in the former and latter cases, seedlings grown more than 60 cm in one year of seedling growth are severely cut, leading to decay of the core, leading to root disease and spontaneous disease, and various pests caused by poor growth. In addition to the severe dormitory, the growth period was delayed for 2 years for the 1st, 3 years for the 2nd and 4 years for the 3rd and 4 years. I'm evading.

As a result, the paulownia trees planted in the former and latter methods are 70% of the amount planted in the 7-10 years, despite the bright future of paulownia trees. -90% failed due to premature aging or death due to root disease, and even the remaining 30-10% of paulownia tree is only 70% when the wood is used for more than 7 years, and 50% is over 10 years. I did.

All the literature, books, and forestry knowledge that have been published to date indicate that paulownia is a natural species because it has planted paulownia trees all over the world, depending only on the former and latter methods. to be.

In order to solve the above-mentioned problems of the present invention, the roots are not damaged at all, and they are grown without necessity, thereby preventing the most fatal root disease in cultivation of paulownia and not being restricted at the time of simultaneous cultivation. -In order to grow to 70-200 or more giant trees in 10 years, it is possible to increase the income of agricultural and mountain villages in a short time and to meet the shortage of timber resources in short time. Or by planting seedlings to plant paulownia seedlings, the growth is much faster than the conventional one, and the growth period is not only long, but also the roots are not decayed because they are grown in pots or teeth and are not cut. There is no worry about it and the cost of raising seedlings is cut in half. In addition, the seedlings can be mass-produced and transported at high altitudes because they do not require short-term roots and donations and become resistant to pests and the harvest season is shortened by 2-3 years.高山 地) is possible and the conventional planting time is from about March 20 to the end of April, but the present invention is also possible until the beginning of June-July every year, which will be described in detail based on the accompanying drawings. .

Selected sterilized soil (3) is placed on a plastic pot (1) with a diameter of 6-7 cm and a height of 15-16 cm (1) as shown in drawing 1, or a tooth (2) with a depth of about 40 cm and a width of 1 m as shown in drawing 4 (4). It is sown and sown the Korean species paulownia seed (4).

Korean true paulownia seeds (4) are divided into 3-5 leaves, about 15-20 cm in size, and silver-white hairs are formed on the back of the leaves. The reason for sowing is 10-15 m in height and chest height 0.9- This is because it grows up to 1.2m and the wood is resistant to cold, which does not distort the wood.

The seeding should be seeded so that the roots 6 are not damaged at all. The method is that the seeded seeds 4, as shown in FIG. 1, are grown only in the pot 1 so that the roots are grown and are not exposed to the outside. Only the vinyl of the sea pot (1) is artificially removed and planted together with the soil or the vinyl (5) can be laid on the bottom of the seeding layer as shown in the attached drawing (4). (3) It should be allowed to grow only inside and not to damage the root (6) during the excavation.

As the root 6 is not damaged, as the seeding process of the seedlings is omitted, the root 6 is not injured, thus preventing the growth of the roots and preventing the corruption of the core. As shown in Fig. 7, reference numeral 7 denotes a paulownia sapling.

In this way, seedling seedlings are reduced to seedlings until they are settled, and the cost of seedlings is reduced, and it is easy to manage, so it is not only economically light but also decayed by conventional excavation seedlings. It will not be affected by the planting season as it will be with the soil, so if left for a long time, it will not interfere with growth and planting, and it will be planted from mid-April to mid-July.

In particular, seedlings and roots are not damaged and lost during planting, and they have good lubrication ability, so they can adapt to formal soils quickly and do not need any retreat work.

If the plant grows due to rain or wind after one year of planting, or grows poorly due to abnormal temperature, it can be grown in two stages by cutting one or two parts of the tofu head once or without cutting it. have.

Therefore, the present invention, in addition to these advantages, shorten the period of seedlings and produce myocardial seedlings, grow strongly against pests, grow 150-200cm after 50 days, 200-250cm after 70 days after planting, 150 days after planting It grows up to 300-400cm (about 5 months) and grows to over 70-200 giant trees in 5-10 years, resulting in 100% utilization rate of wood production.

Example 1

First install the port seeding phase.

After installing the plastic house, make 2 ~ 4 heads in the house with 1m of seeding area and 0.7-0.8m of furrow between the head and the head.

The sand loam is then beaten with a 3mm mesh to remove stones and miscellaneous material, followed by soil sterilization.

Here, the soil and the mature compost ratio is 10: 1 (volume ratio), and then finely crushed, and the soil pesticides and fungicides are evenly mixed to disinfect the soil and left for about 24 hours, and then placed in a 6cm or plastic bag. Cut it up to 15-16cm in length and make a plastic pot with topsoil.

The plastic pot is set up in 320 to 360 places in 100cm all around and sprayed with water so that the top soil gets wet. Seeds are sown here. Before sowing seeds, the seeds are soaked in a seed disinfectant such as Uspulun or clear urine for 15 hours and then harvested.The seeds are soaked in a flour bag and removed and stored for one day. Let the water drain slightly.

With this ratio of seeded soil and seeds in a ratio of 10: 1 (volume ratio), sowing is carried out so that about 3-5 seeds fall in the center of the pot. After sowing, cover the fine soil so that it is not visible as a seed.

Cover the straw thinly so that the seedling soil is not visible, then spray the water evenly so that the covered straw is soaked, mix it with a disinfectant and an insecticide, and cover it with 0.03mm vinyl to prevent moisture from evaporating.

The vinyl at the edges should be covered with dirt to help prevent moisture evaporation.

At the end of the work, keep the house temperature at 180 ° C-30 ° C and the humidity at 80-90%.

It usually germinates after 12-15 days, so germinate and simultaneously roll the vinyl and straw, mix the fungicide and the pesticide, and sprinkle it.

Then, 2m long bamboo plugs are put in place, and vinyl is covered to make a vinyl tunnel. The heating system keeps the room temperature at 18-30 ℃ and the humidity at 80-90%.

Especially, to keep warm, remove the sun crab during the day and cover it at night.

After germination, weeding works thoroughly. When 4-6 sheets of main business, only one strong seedling is placed in the middle, and the rest is shredded.

After germination, drug spraying for the control of stock and anthrax is continued at intervals of 1 to 10 days.

Usually, 90-100 days after planting, it grows into a 13-15cm standard seedling, which is transferred to the pot planting plant as it is, and only the vinyl is removed in front of the planting pit and planted in the pit with the planted soil.

Example 2

Place a 1m-wide and 40cm-long pit where the seedlings will be installed, and spread 0.05-0.07mm thick vinyl evenly on the floor and sidewalls to prevent the roots from passing through it, and then select and disinfect the soil as in pot seedlings. Fill in about 40cm while pressing.

After flattening, seed sterilization, such as pot seedlings, is also carried out with a soil to seed ratio of 10: 1 (volume ratio).

Sowing should be done in June-August. After sowing, sterilize in the same way as for pot seedlings.

It germinates after 10-15 days, and at the same time, germinates and walks with straw and vinyl and sprays insecticides and fungicides to prevent pests such as wearing diseases and anthrax, like pot seedlings.

In particular, in order to prevent damages such as high temperature and showers, install a shading so that the room temperature is 20-30 ℃ and the humidity is 80-90%.

After germination, walk and manage straw, like pot nursery, so that the distance between seedlings is about 18-20cm, weeding and pest control.

The seedlings are grown for about 50 to 60 days so that the size of the seedlings is about 30-50cm so that the seedlings do not freeze by installing low vinyl tunnels to prevent frost and the East Sea in autumn.

In the next year of planting, the soil should be removed from the seedlings so that the roots are not damaged.

This is a method of producing suitable seedlings that do not spoil the roots for planting by suppressing the growth and growth of the roots by sowing on July 20-30. Conventionally, the growth period is extended by sowing until the end of March-mid-April. 60-100cm roots, the length of the seedlings will grow more than 1m, so the root can not be cut without damaging the excavation.

Therefore, the dental nursery is a method of planting the roots together with the pot nursery so that the roots are not damaged at all.

Seedlings obtained from dentate nursery are planted in the following mid-April to mid-April, and after planting, the ground part is cut off once or with no head, and only 1-2 parts of the tofu are grown in two stages.

On the other hand, the planting time of seedlings by pot nursery is planted at the end of April 20-May, planting about 600 plants per ha, although there are some differences depending on management purpose, topography and region.

Pits for planting should be 50-60cm deep and 100-120cm wide, but the wider the effect, the better.

Pits are planted with 8-10kg of compost and 80g of fertilizer per 12 trees.

When planting pots or toothed seedlings are transferred to the planting season until planting to prevent root damage.

In the prepared pit, spray about 20g of soil insecticide on the surface, scrape with hoe, mix with soil, and plant seedlings. Pot nursery must remove the plastic from the pot in front of the prepared pit.

Pot saplings are placed in a pit so that roots and soils are not damaged and covered with soil about 3-5cm from the root of the seedlings buried in the pot.

When planting soil, be careful not to make a puddle, and when you step on the soil, step on the outside of the seedlings 10cm. When this is done, cover the area with fallen leaves or dry grass.

After 7-15 days of planting, 250g of compound comparisons per 12 trees should be fertilized about 20cm away from the seedlings.

In between June and September, mow around 2m or perform laver three times. In the middle of September, the last three times of mowing are done with full under mowing.

The first fertilization from the following year to early March-late March, and the second fertilization from early June to mid-June, the grass produced by the mowing grass is set at 1.2m around the paulownia tree to rot.

In order to control pests during planting, apply a disinfectant and insecticide once a month until May-August. Broom disease rarely occurs in plants planted by pot nurseries because roots grow vigorously into wholesome seedlings without injury.

The present invention as described above is fast growing so as not to damage the roots, so that the main roots are not cut and developed and do not fall down to be resistant to pests, so the wood can be obtained with a superior material, and the harvesting period is shortened by 2-3 years, hair growth cost is reduced. In addition to the savings, it is effective in mass production and transportation of seedlings.
