The present invention is a timber planting of salted ground, which is constructed so that the planted plants can grow early and grow well even in poor salted soil where the salt content is high, such as the coastal landfill filled with dredged sandstone from the seabed. It is about a method.

There are several ways to expand the land. One of them is the reclaimed land reclamation project in which shallow seas are reclaimed with cancer and earth and sand, and various industrial complexes and public facilities are located.

After the construction of public facilities such as water, sewage, roads, and buildings on the vast landfills obtained by reclaiming the sea, installation of so-called landscaping facilities to create the surrounding landscape is essential. The construction of landscaping facilities does not involve any problems, but the construction of removing trees and lawns is often difficult because the salt does not grow properly and the trees are not able to die or be successful.

Most of the coastal landfills are filled with dredged sandstone from the sea bottom of the nearby sea, so the salt content is very high, which is very unsuitable for the growth of trees.

The impact of salted soil on trees can be classified into three types: direct damage caused by salinity, drought damage caused by destruction of soil tissue, and deadly damage caused by malnutrition.

Of these three damages, the most important is the movement of soil water that cannot be artificially handled. So, the movement of soil water was observed from various angles, and it was classified into the following four types and analyzed for the cause and applied to the present invention.

That is, it is effective moisture necessary for the movement of water in the soil and the growth of plants. The movement of water in the soil is first downward movement of water, second upward movement of water, third movement of maternal force, and finally evaporation movement of water vapor. According to the research results, when the self-cleaning action is possible under these four conditions, the most economical and natural planting base is established, which facilitates the growth of planted trees.

1 downward movement of water

Rainwater or irrigation water penetrates into the surface crevices of the soil, where water penetrates large voids and flows downward by capillary force and gravity. However, even if water seeps into the voids, the whole voids are not filled with water. As a rule, 10-30% of the void volume in the soil is air or gas. The air or gas is compressed under water pressure, and the volume of the compressed gas is less water.

So, as the water supply decreases, soaking water decreases as it goes down. In addition, when there is a lot of water, it descends by gravity and maternal force, and when there is little water, the movement of water is stopped to some extent only by maternal force. Naturally, when water flows down by gravity, the movement of water varies according to how large voids exist. Sandy soils move faster, but slower in clay layers.

2. Upward movement of water

Water in the ground, such as groundwater, overcomes the resistance of gravity and rises by capillary force. In sandy soils, the rate of rise of water is high, but the height is low.

3. Movement by Maternal Force

When water is not supplied separately from the outside, if one of the waters which depended on each other among the earths in the ground decreases, water of the earths (a, b) moves toward the other earths (c) as shown in FIG. When the thickness of the water film becomes constant, the water stops moving. This movement of water can be moved either up, down, left, or right because it can move only by the capillary force regardless of gravity.

4. Movement as water vapor

Water that cannot be moved by the capillary force is easily moved once it turns into water vapor. In other words, when there is a difference in temperature, water evaporates and moves to water vapor at a high temperature, which condenses and turns back into water at a low temperature. This is evidenced by the fact that when the surface soil becomes cold at night, warm water vapor from the lower layer rises and condenses. Therefore, where the temperature difference between day and night is severe, water movement is possible by using this steam function.

Atmospheric air is 79% nitrogen, 21% oxygen, and 0.03% carbon dioxide. Soil air is almost saturated with water vapor due to a decrease in oxygen concentration and an increase in carbon dioxide concentration. Therefore, it is very important to promote the conversion to effective moisture by controlling the amount of water for packaging and the situation of forgery point by the same action as the above four items.

Therefore, the present inventors have deeply studied and studied deeply about the environment composition where trees and grass can grow even in soils with high salinity. After discovering a merit to provide an environment where grass can grow properly, the present invention has finally been proposed.

The purpose of the present invention is to plant trees that are planted so that they can grow properly by growing early in the poor salted soil where salt content is high, such as in the coastal landfills filled with dredged soils dredged from the seabed. It is to provide a planting method.

The present invention employs a planting structure consisting of a U-shaped curved pipe having underground tuft beams located deepest in the ground and volatilized tuft beams exposed to the surface, and a diaphragm which physically isolates the landfill and the clay, and has a distribution specifically formed therein. By using the high salt content in the salted planted trees or grass is characterized by creating a foundation that can grow like that grows well in the general soil.

In the curved pipe, a pipe of a material having excellent corrosion resistance, acid resistance, alkali resistance, chemical resistance, and heat resistance is bent, and the curved pipe is formed by a diaphragm formed by a diaphragm in an area having a high groundwater level or a high salt concentration. It completely blocks the intrusion of salt which is easy to penetrate into the pot.

At the deepest point of the bend of this bend, a beam hole is drilled, and underground bundle beams are planted, which induces excess water more than the effective moisture from the rainwater or irrigation water that soaks into the soil and flows into the pipe. Poetry plays a role in guiding the water stored in the curvature to be supplied to the soil by the capillary phenomenon of the underground bundle beam.

Volatile beams are embedded at both ends of the elbow. The role of this volatile beam is to suck up water, water vapor in the pipe, and the salts in the salt ponds that flowed into the pipe due to the rise of the temperature, the filling of the stored water, the evaporation and the capillary phenomenon inside, and so on. This is to accelerate the growth of planted trees by exposing the materials that are not necessary for growth to the wind as soon as possible to the surface of the ground and solar heat. In this way, it is expected to play a role of midnight to help the renewal of soil air, and to achieve the purpose of storing adequate water and supplying water to the soil.

In addition, the diaphragm is a sheet made of a synthetic resin film such as polyethylene, and is effective to physically isolate the soil and the distribution of the salted paper so as to suppress the influx of salts harmful to the growth of trees into the pot formed by it.

In addition, the distribution is composed of a hardened material layer, a gravel layer mixed with sand and a hardened material, and a cultured soil mixed with landfill soil and artificial soil from below. The gravel layer prevents oxidation and decay of the soil and its mixture in the planting yard and at the same time facilitates drainage of the soil. Cultured soil is an artificial soil containing various nutrients containing essential ingredients for the growth of landfills and trees. It is used in combination at a ratio of 3: 1.

Hereinafter, the present invention will be described in detail.

In the present invention, a special planting tool (A) is proposed. This planting zone (A) is a curved pipe (1) with a underground bundle beam (2) located deepest in the ground and a volatile bundle beam (3) exposed to the ground (G, R), and a reclaimed soil (5) and clay It is a diaphragm 4 and the soil 6 which isolate | separate (6) physically.

The curved pipe 1 is a pipe made of a material having excellent corrosion resistance, acid resistance, alkali resistance, chemical resistance, and heat resistance like a synthetic resin pipe by bending a flat pipe into a U shape. The bend pipe 1 is used together with the diaphragm 4 to penetrate into the planting port A, in particular the pot for planting formed by the diaphragm 4, in an area having a high groundwater level or a coastal landfill with a high salt concentration. It completely blocks the salt from easy salting.

The bend 1 has a small hole of a beam hole 7 bored at the vertex of the deepest part of the pole bent portion, and the underground bundle beam 2 is planted therein. This underground beam 2 is constructed to penetrate into the base of the clay 6. The underground beam (2) is a wick. That is, when there is too much to accommodate both rainwater and irrigation water that soaks into the soil 6, the excess water more than the effective water passes through the gravel layer 61 of the lowest layer, and then the beam hole 7. Inflow into the curvature (1) through and stored.

In addition, when the soil 6 is gradually felt, the water stored in the curved pipe 1 is sucked back into the soil 6 by the capillary phenomenon of the underground bundle beam 2. This provides a place of so-called automatic water supply that can last for a long time without rewatering.

On the other hand, the volatile beam 3 is planted at both ends of the curved pipe 1, and the volatile beam 3 is formed by the rise of the ground temperature, the filling of the stored water, the evaporation phenomenon in the inside, and the capillary phenomenon of the volatile beam 3 itself. 3) Ride into the ground. The sucked water acts as a volatile medium that blows into the atmosphere with the help of changes in air temperature and wind flowing near the surface.

It also expects the role of a magnetic field to help the renewal of soil air by exchanging gas between the air and the air in the vicinity of the soil, and can achieve the purpose of storing water and supplying adequate water to the soil (6).

On the other hand, the diaphragm 4 is a sheet made of a synthetic resin film such as polyethylene, and preferably, after several years have elapsed after reclaiming with sandstone, the salts of the landfill soil 5 are washed away by fresh water and weathering to grow trees. Until the soil is stabilized enough, the mold will be properly supported and then decomposed by itself and selected as a material for planting.

The soil 6 is composed of a hardener layer 61 in which sand and a curing material are mixed from the bottom, a gravel layer 62, and a culture soil 63 in which landfill soil and artificial soil are mixed. The gravel layer 62 is for preventing oxidation and decay of the clay and its mixture in the planting sphere A, and one of the reasons is for smooth drainage of the clay 6. The culture soil 63 is used by mixing artificial soil containing various nutrients containing essential ingredients in the growth of landfill soil and trees in a ratio of 3: 1. In addition to landfill soil, it is also possible to use unpigmented soil such as ocher.

Next, an example of an effective method of planting trees in salted water will be given to help the understanding of the present invention.

In the landfill (5), which is buried with sandstone, dug-hole pits (8) having a diameter of ø1800, a diameter of 1200, and a height of 1400 mm are sold at intervals of 3 m.

On the other hand, a ø200 synthetic resin pipe is prepared by bending a U-shaped bent pipe 1 to fit into the cross-sectional shape of the pit 8, and a beam hole 7 smaller than its inner diameter is drilled at the apex of the bend, and then the beam hole 7 The underground bundle beam 2 and the volatile bundle beam 3 are planted at both ends of the curved pipe 1 so as not to be reversed at will unless a strong external force is applied.

At this time, the underground bundle beam (2) is fully embedded in the beam hole (7), the upper part of the half length or more to enter the beam hole (7) and the volatile beam (3) is approximately half of its end of the curved tube (1) Plant it out to be exposed. Thus, the curved pipe (1) in which the underground beam (2) and the volatile beam (3) is planted is placed in a pit (8) that has been dug in advance.

Subsequently, a diaphragm 4 having a size corresponding to the entire inner area of the pit 8 is prepared, and a perforation beam hole 9 of a size sufficient to fit the trough beam 2 is drilled in the abdomen, and then it is gently swept over the curvature 1. Sit in At this time, the beam hole 9 is fitted into the underground bundle beam (2). In this way, when the installation work of the study tool A is complete | finished, the diaphragm 4 becomes a kind of port.

A layer of hardener 61 mixed with sand and hardener from the bottom in the pot was laid on the diaphragm 4 thus formed, about 10 cm thick, and the remaining gravel layer 62 was 20 cm thick thereon, and then the remaining space thereon was reclaimed from landfill or It is filled with the alignment soil (63) which mixed 75% of yellow soil with 25% of "green soil".

If the roots of the transplanted tree are properly rooted and growth is strong, the treated layer of the planting sphere (A) is not a problem later. The reason is that the diaphragm (4) is oxidized and the hardening layer is weathered by oxygen from the roots of trees and organic acids such as humic acid generated from soil organic matter.

As described above, a planting tool (A) consisting of a pot for planting formed by the curved pipe 1, the underground bundle beam 2, the volatile bundle beam 3, the diaphragm 4, and the specially prepared clay 6 When planting small trees in salt areas, such as coastal landfills, where tree growth was difficult due to high salt concentration, artificial soil (green soil) lowers the salt concentration of landfill soil and absorbs moisture during rainfall. Moisturizing prevents the drying of the soil at a drought, and also provides poor nutrients to the poor soil by granulating poor soil tissues. Of course, the planting ground of trees also has a gradual combustible change, that is, filtration of salinity due to rainwater, change of groundwater level, and adaptability to salinity are increased, so that trees can grow smoothly after planting. It can promote the early recording industry over Doha.
