ASEXUAL PROPAGATION METHOD FOR GOLDEN PINE TREE USING GRAFTING}

The present invention relates to a method of asexual breeding through grafting of golden pine leaves having a golden color, sowing general seedlings, germinating them, transplanting them to form large trees (臺 木), and golden pine ( Pinus densiflora for aurescens) . It is a grafting method of golden pine which can be reproduced in large quantities by taking Uyeki as a parameter and growing it in shading vinyl house.

Golden pine is a plant of the family of pines and has the characteristic that the color of the leaves except for the base is golden, very rare in the natural state, and may appear as azo mutation in the general pine.

This golden pine has a high ornamental value due to its unique color, but there is a small number of individuals in the natural state, and it is difficult to breed.

Referring to the detailed process of the present invention with reference to the accompanying drawings as follows.

As shown in Fig. 1, the general brush is sown on the base plate 91 and grown for about a year, and then planted at a regular interval d of about 10 cm on the planting field 99.

Plantation 99 is a place where the growth of the golden pine grafting and seedlings (30) is to be later installed facilities, including the plastic house 93, preferably located on a flat.

These pine trees that have been planted are grown for another year to form a large tree (10), and grafts (21) taken with golden pine as a parameter (20) are grafted.

The reason for forming the big tree (10) through the planting process after the seeding of the brush is to grow as the big tree (10) as healthy as possible, and the golden pine which is the reception tree (21) to be grafted to the big tree (10) later is general. Given that it is a rare species with low adaptability compared to pine trees, the condition of the large tree 10 also affects the success rate of grafting as well as the overall growth after grafting. Thus, in the present invention, such a planting process must be made before the grafting. It's a process.

In the conventional general pine grafting to remove all the pine needles of the pine tree (10), but the grafting was carried out, in the present invention to leave about 10 to 15 pine needles in the tree, which is grafted to the upper reception 21 (21) In order to supply moisture and nutrition smoothly.

In taking the reception 21, the new sprout which is in a state which has passed about 1 year after germination is selected, and it is grafted to the big tree 10 by the splitting method.

Reception 21 is collected so that the length is about 7cm to about 10cm, pine needles leaves only about 10 to 15.

In addition, depending on the situation, there may be a case where the grafting cannot be performed immediately after the collection of the reception 21, and in this case, the collected reception 21 may be stored at a low temperature before use.

In the low temperature storage of the reception 21, it is necessary to maintain the proper temperature and humidity. For this purpose, the reception 21 is wrapped in a damp cloth and then wrapped with vinyl again and stored. The internal temperature of the low temperature warehouse is maintained at about 5 ° C. Humidity should also be kept high.

The big tree 10 is cut at a distance of about 10 cm to 15 cm from the ground to the cutting plane, and then grafted with a length of about 2 cm at the joint length h1, which is divided to join the reception 21. The joints are wound around the cotton yarn 92. The reason for using the cotton yarn 92 is that it has superior biocompatibility and natural degradability than fibers of synthetic resin series.

At this time, the graft can be successful even if the graft (h) is different, but in order to secure the success rate or growth rate after the graft, it is preferable to use more than 10cm, the graft results according to the graft (h) is shown in the following table.

division Large tree (h) Graft Success Rate Growth rate Low contact 3 cm 60% Slow Medial 5 cm 75% usually Tack 10 cm 90% speed

The grafting is performed by dividing the central portion of the large tree 10 and trimming the distal end portion of the reception 21 into a wedge shape having two cut surfaces, such as the enlarged part of the circle in the same drawing. The length of (21) is preferably about 5cm to 8cm, and since a small amount of space is usually required for trimming the distal end portion of the collected reception 21, it is preferable that the reception 21 be collected at a length of 7cm to 10cm.

Looking at the coupling method of the reception 21 and the tree 10 in the graft in detail, as shown in Figure 7, the reception 21 is inserted between the split tree 10 in a fan-like shape when viewed in plan view Preferably, this is to increase the success rate of grafting by making the split surface of the log 10 and the cut surface of the reception 21 close to each other as much as possible, and the formation layer of the log 10 and the reception 21 to be in contact with each other.

That is, the cross section of the distal end of the reception 21 trimmed for grafting is composed of a pair of cut surfaces and a pair of circular arcs between them, and the reception 21 is coupled between the divided surfaces formed in the tree 10. In the case, as shown in Fig. 7, the large circular arc is coupled so as to be positioned to the outside, the bark 10 and the bark of the reception is to be in contact with each other.

The grafting is preferably performed in February not only on the growth characteristics of the parameter 20 and the reception 21, but also on the growth conditions such as the temperature after grafting.

After the grafting is completed, the plastic house 93 is installed on these grafted pine trees, and the light is blocked by covering a light shielding film 94 having a light shielding degree of about 90% thereon.

In the installation of the vinyl house 93, it is preferable to install it long in the north-south direction as shown in FIG. 4, in order to minimize the solar radiation before and after the south middle of the sun.

In addition, as shown in FIG. 5, it is preferable to have a good growth state of the large tree 10 so as to be located at the center of the vinyl house 93. This is because growth of the edge of the vinyl house 93 is vigorous, so that the overall growth state is kept constant. To do that.

The internal temperature of the vinyl house 93 is kept relatively cool at 10 ° C to 25 ° C and the internal humidity is maintained at 60% to 80%.

When grafting is carried out in the spring, the growth period in the vinyl house 93 is mainly from March to June, so the key to maintaining the proper internal temperature and humidity of the vinyl house 93 is to prevent the increase in internal temperature. Proper ventilation

In late spring or early summer, due to the high altitude of the sun, the temperature in the vinyl house 93 rapidly rises to 50 ° C. or higher in the middle of the day. Temperatures often exceed 30 ℃, so special care is required.

In case of young seedlings (30), if the temperature is kept above 35 ℃ for a long time, it is highly likely to die, and if it is below -5 ℃, it is often cold. In the case of the young seedlings (30) grafted to (21) is often killed even if left for about 2 hours at 25 ℃ or more, the graft success rate is significantly reduced when using a conventional vinyl house (93).

In the present invention, as shown in FIGS. 4 and 5 by forming a plurality of upper cutouts 96 and side cutouts 95 on the top and both sides of the vinyl house 93, thereby allowing natural ventilation through the interior. As shown in the figure, these incisions were cut in a T-shape after 20 days of grafting, and the degree of opening was increased according to the flow of air by the elasticity of the vinyl house 93 vinyl. To change.

After the grafting is completed, just before the vinyl house 93 is installed, pesticides such as insecticides and fungicides are sprayed to prevent pests such as pine needle black fly or pine re-nematode, also known as pine AIDS. This is because the inside of the vinyl house 93 is kept sealed for about 20 days before the incision of the plastic house 93 for ventilation, and the spraying effect of the pesticide is doubled.

In particular, the final product of the present invention is a seedling (30) to be scattered and planted in various places to be a host of various pests to act as a medium for spreading pests, it is very important to spray pesticides at the appropriate time.

As can be seen in Figure 5, the outside air flow in the plastic house 93, the outside cool and fresh air is introduced through the side cutout 95, the internal hot through the top cut 96 The cloudy air is made in such a way as to be discharged.

After maintaining the temperature, humidity and shading conditions for 3 to 4 months, the light shading state is gradually released over about 15 days, so that the grafted golden pine tree can adapt to sunlight (Taeyang Light) to make the seedlings (30). Complete

The shading of the vinyl house 93 is performed by installing a shading film 94 on the outside of the vinyl house 93. The shading film 94 is a fabric that is roughly woven with synthetic resin or the like, and has a shading degree of about 90%. , Using a separate frame as shown in Figure 4 is installed to be spaced about 20cm away from the surface of the vinyl house 93.

In general, the light shielding film 94 is manufactured in a black-based color for the light shielding effect. When the vinyl house 93 and the light shielding film 94 are installed in close contact with each other, the radiant heat absorbed by the light shielding film 94 remains in the vinyl house 93 as it is. Not only can be raised to increase the internal temperature, the operation of the top cut portion 96 and the side cut portion 95 formed in the vinyl house 93 also interferes with the space between the vinyl house 93 and the light shielding film 94 To install.

When the above-described process is completed, after removing the plastic house 93, the shading film 94 is also gradually removed. When releasing the shading state, the shading film 94 is completely removed in cloudy weather, and the shading time is clear in sunny weather. The seedlings 30 are adapted to sunlight while gradually lowering the light shielding degree by gradually adjusting the completion of the light shielding state by a method such as gradually reducing the light shielding state or by gradually replacing the light shielding film 94 having a low light shielding degree.

In order to reduce the shading time, the shading film 94 is installed on the basis of sunrise and sunset. That is, the first day 30 minutes after sunrise, the light emitting film 94 is installed 30 minutes before sunset, and the second day is sunrise 1 After a time, the light shielding film is gradually reduced by installing the light-emitting film 94 and removing the light one hour before sunset.
