The present invention relates to a method for the early afforestation of the useless ground, more specifically, to a method for the early afforestation of the useless ground by aerial dropping the vegetation structure onto the ground with an airplane such as helicopter.
Up to the present, in order to afforest the useless ground such as the inclined ground, there has been study for developing a method for the afforestation of the inclined ground in which the inclined ground was being covered with a net or a concrete.
The Korean Patent No. 10-729417 disclosed an afforestation structure composed of a net, a soil wall layer and an upper soil layer. The Korean Patent No. 10-661852 also disclosed a method for the afforestation of a slope surface of inclined ground without using a fiber net, a net or a concrete, in which a cultured soil was prepared by mixing with fermentation solution and the cultured soil was molded on the inclined ground, and a sprouting seed was scattered.
The Korean Patent No. 10-542729 disclosed a method for the installation of a block for reinforcing afforestation on a slope surface of inclined ground, and The Korean Patent No. 10-473540 disclosed a method for developing an afforestation by fixing a bag filling with earth and sand onto the ground with a fin to prevent a loss of soil. The Korean Patent No. 10-426129 disclosed a method for the afforestation of inclined ground in which inclined ground was covered with a diaper wire net and fixed with anchor fin and then an artificial green soil composition was applied onto with the thickness of 20 cm.
However, there is a problem that these methods for the afforestation were only suitable for the inclined ground and cannot apply to extinguished ground, dune ground, barren ground, steep slope ground or bedrock ground.
Accordingly, the purpose of the present invention is that the vegetation structure in which plant is grown and hardened in the preliminary prepared structure, is aerial dropped onto the useless ground with an airplane such as helicopter and necessary measures such as molding, treatment or application with inhibitor for the evaporation of moisture to reduce a labor power and to secure the afforestation.
The purpose of the present invention is achieved by preparing the vegetation structure with regular shape suitable for each kind of useless ground and filing mixture of seed, rooting promotor and soil into the vegetation structure and fixing the vegetation structure directly or with putting in sand bag, and then rooting and growing the vegetation structure in the outdoors or greenhouse, and directly dropping the vegetation structure onto the useless ground with an airplane such as helicopter such that the vegetation structure is subject to root early and stably on the useless ground.
According to the present invention, vegetation material that is sufficiently grown and hardened in the vegetation structure such as artificial wooden port is directly aerial dropping on to the useless ground to make possible to naturally afforest the useless ground such that the present invention is very useful in the industry of landscape architecture and vegetation because a labor power is epochally saved and security of afforestation is early achieved to effect on carrying out the early vegetation of the useless ground.
a is showing the vegetation state of a coniferous tree and
b and 6 are showing the artificial port of wood as the vegetation structure of the present invention.
a and 7b are the artificial port for aerial dropping in which a number of plant seed can be sown and grown in various type of vegetation structure to afforest the useless ground in accordance with the preferred embodiment of the present invention.
In the followings, the present invention is more detailed described with reference to the attached drawings.
a and 2b are showing a coniferous tree (2) or a broadleaf tree (20) grown in the vegetation structure (1) suitable for aerial dropping onto the useless ground with an airplane in which the vegetation soil (3) made by mixing the artificial soil, fertilizer, seed and the rooting promotor is inserted into the vegetation structure (1) and seed is sprouted, rooted and hardened in the vegetation structure (1).
In the result of experiment, the wooden port of the present invention preferably has 3-8 mm of thickness, and most preferably has 5 mm of thickness based on two months in both of a coniferous tree and a broadleaf tree in consideration of time for taking root through the wooden port.
In the present invention, the soil composition for the vegetation which is the growing medium of plant seed, is an artificial soil, preferably peat moss. A rooting promotor for plant seed can be used suitable for a coniferous tree and a broadleaf tree, and amount of 0.1 weight % of the artificial soil is preferred.
The vegetation structure of the present invention, for example the conical wooden structure, as shown in
The probability that the structure of the present invention will be broken on dropping at 100 m of height from the ground, is below 0.01%.
In the preparation for such circumstances, the conical wooden structure of the present invention comprises sand bag therein and thus it can fix the opening of the structure when artificial soil, fertilizer, seed and rooting promotor are mixed and inserted, such that the conical wooden vegetation structure can be used from the beginning.
Such conical vegetation structures are preferred for the afforestation of the inclined ground, the dune ground or the tropical rain forest having much of solid waste compost.
In addition, the vegetation structure of the conical sand bag type which is substituting for the conical wooden type would be an embodiment of
It can be preferred that the opening of the structure (1) in which plant is grown by sowing seed into soil with fertilizer should be tightly tied with a rope (4) to prevent from spilling off the soil with impact in the dropping.
The vegetation structure of the present invention is suitable for applying to the useless ground such as the bedrock ground of rocky mountain or the hill ground on which the structure can be easily destroyed on direct aerial dropping. Roots of the vegetated plant secrete a material capable of dissolving the second mineral of rock via root cells, and root hair cell physically pass through the dissolved place to take root. The structure of natural fiber (1) can be preferred to prepare with hemp thread having thickness capable of preventing from sleeping in order to keep away from rolling over bedrock of rocky mountain.
The vegetation structure shown in
Such vegetation structure is suitable for the afforestation of bedrock ground in a rocky mountain because it does not easily rolling.
In addition, other embodiment of the present invention is shown in
Such vegetation structure is preferably made by natural fiber such as cotton or hemp, and most preferably has the bottom and the three side of regular triangle or isosceles triangle type.
The vegetation structure having such constitution and type is characterized in that the vegetation structure is a polyhedron in which four faces are formed regular angle and can be easily landed on the ground without sliding and can minimize the damage of plant when the vegetation structure containing plant (20) which is regularly grown by sowing seed into the artificial soil composition composed of fertilizer, rooting promotors and soil, is aerially dropped.
Another preferred vegetation structure of the present invention is shown in
Except for the vegetation structure of wood in
Therefore, the vegetation structure of wood having a regular or rectangle polyhedron type are appropriate in the early afforestation of the dune ground or the inclined ground, and the vegetation structure of natural fiber having a regular or rectangle polyhedron type are appropriate in the early afforestation of the bedrock or the inclined ground because it has high friction coefficient due to the multi-side construction.
Besides, the vegetation structure of wood having cylinder conical type is shown in
The vegetation structure of wood having such type and constitution can be applied to the early afforestation of the dune ground or the solid waste compost ground.
In addition, when the vegetation structure is made by a natural fiber instead of wood as shown in
In the present invention, as the fertilizer, the composite fertilizer in which nitrogen (N), phosphorous (P) and potassium (K) are mixed with micro elements, can be used in amount of less than 10 weight % of the soil composition.
Accordingly, the present invention is distinguished in that the environmental friendly port can be broadly applied and the custom-made vegetation structure can be coexisted in accordance with the useless ground.
Another preferred embodiment of the present invention is to provide the early afforestation method in which seeding and growing a various of plant seed in an artificial port of natural fiber and then dropping the port of vegetating plants onto the ground by an airplane (5).
The present invention can provide the environmental friendly custom-made vegetation structure suitable for the early afforestation of the useless ground with an airplane, and thus the present invention is very useful for the forestation industry of the useless ground.
