DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the growth of plants planted on slopes such as flat park green spaces or sloped road shoulders, lands, and the like to cover the ground, thereby covering the ground with natural light, wind and rain. The present invention relates to a greening method for preventing and preventing erosion and collapse of trees, stabilizing protection, and maintaining and improving the landscape by greening.

[0002]

2. Description of the Related Art Conventionally, lands are eroded and collapsed by natural light, wind and rain by planting plants on park green lands, road shoulders, lands, etc. to promote and promote growth and cover the ground. To prevent and stabilize protection,
Various techniques for maintaining and improving the landscape by greening are known. For example, JP-A-6-185066 discloses that a bag-like planter made of polypropylene thermocompression bonding nonwoven fabric is hooked and fixed to an anchor such as a concrete nail or a pin which is driven into a concrete slope or a surface soil. Seedlings planted in the planter are promoted and promoted by the culture soil and fertilizer put in the planter, and the roots are sufficiently extended through the planting holes provided on the concrete slope, or the seedlings are directly extended on the slope topsoil. There is described a technique for fixing the ground to the ground.

[0003] Japanese Patent Application Laid-Open No. 8-246467 discloses a method in which grass seeds and the like are attached to a sheet made of non-woven fabric, stretched on a slope and fixed with pins, and openings are provided at predetermined intervals on the surface of the sheet. The mountain is excavated, and seedlings are planted in the excavation area together with a plastic pot or through a plastic container made of bamboo from the plastic pot, and the sheet surface promotes the growth of undergrowth such as lawn and planted in the opening at the same time. Techniques that promote the growth of planted seedlings are described.

Japanese Patent Application Laid-Open No. Hei 9-217353 discloses a technique for promoting the growth of turf and the like by fixing a biodegradable mat and a sheet containing plant seeds such as turf with pins and covering the slope. Is described.

[0005]

According to the above-mentioned technique, the plant extends only to the planting hole on the concrete slope, and the concrete part is uncovered and uncovered. The purpose of maintaining and improving the quality of the project cannot be sufficiently achieved. On the other hand, in the embodiment where the slope is directly constructed on the topsoil, before the seedlings sufficiently settle on the slope and grow to the extent that contributes to the protection and stabilization, the slope is eroded or collapsed by natural light, wind and rain, or There is a drawback that weeds and bushes are growing on the slope and hinder the growth of planted seedlings, and the objectives of protection and stabilization of the slope and maintenance / improvement of the landscape are not sufficiently achieved. Furthermore, the planter remains permanently without biodegradation,
There are also disadvantages that pollute the environment and spoil the aesthetics. In addition, the installation work of the planter requires the work of excavating holes for planting on the slope and the difficult work of driving many anchors,
There is also a disadvantage that the work process becomes complicated.

[0006] The above technique is used when a vinyl pot is used and when the covering sheet is made of a material that does not biodegrade.
Also, there is a disadvantage that the plastic pot and the covering sheet remain permanently, polluting the environment and impairing the appearance. Furthermore, bamboo planting containers are not suitable for mass production and mass use, and have the disadvantage of increasing costs. In addition, the spreading of the covering sheet, the excavation of the hole, and the planting of the seedlings are separate and difficult tasks, which are several steps. Therefore, it is not suitable for protecting and greening a slope having a large area in a short period of time simply and at low cost, and has a disadvantage that it cannot be said to be practical.

In each of the above techniques, the operation of driving an anchor into a slope and the operation of planting seedlings and the like on the slope are separate and independent operations, and there is a disadvantage that the same location cannot be temporarily constructed. . It can be appreciated that the above-mentioned technique is a nonwoven fabric sheet formed of inexpensive biodegradable plastics, which is a rare and expensive imported material such as coconut fiber, which is a cause of natural destruction. However, it is implemented only to promote the growth of undergrowth such as turf, and planted seedlings (trees)
It is not possible to stretch the roots and embrace the soil to protect the slopes. In addition, there is a disadvantage that weeds that are taller than turf and the like are prosperous and hinder the growth of the turf and the like, sowing or sowing turf is destroyed, and the object of maintaining the aesthetics and maintaining and improving the landscape is not achieved.

Accordingly, an object of the present invention is to suppress the overgrowth of weeds and bushes, to promote the growth of planted seedlings, and to make the seedlings thrive and fully rooted, so that not only flat park green spaces, but also roads In addition to preventing erosion and collapse due to natural light, wind and rain, etc. on slopes of slopes such as shoulders and constructed land, protection and stabilization, it is especially effective in greening slopes to maintain and improve landscape, and When the seedlings are sufficiently rooted and the branches and leaves are prosperous, the biodegradable covering sheet and the seedling pot are naturally decomposed and do not return to the soil to pollute the environment. It is an object of the present invention to provide a revegetation method that can temporarily and simultaneously perform the work of planting seedlings, and that is particularly suitable for revegetating a large area of ground in a short period of time at a low cost and simply.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the greening method according to the first aspect of the present invention, a sheet 1 is laid so as to cover the entire surface of the ground 2 as shown in FIG. The sheet 1 only needs to have a material and strength suitable for suppressing the growth of weeds and trees that will grow on the ground, and a biodegradable sheet is suitable, but a normal plastic sheet, paper, or cloth Sheet or the like.

The seedling raising pot 3 has a strength suitable for driving into the ground and a sharp lower portion, for example, as shown in FIG. The strength of the seedling raising pot 3 only needs to be strong enough to hit the upper part of the seedling raising pot 3 with a hammer or the like and drive the lower part into the ground to a sufficient depth. The lower portion may have any sharp shape suitable for being driven into the ground, and is not limited to the conical shape shown in FIG. 1, but may be, for example, a pyramid shape or a shape obtained by diagonally cutting a columnar body. The size of the seedling pot 3 shown in FIG. 1 is about 15 cm in height and about 7 cm in maximum width,
Change as appropriate according to the size of the seedlings to be planted.

A seedling 4 is planted in the seedling raising pot 3. It is desirable that the seedling raising pot 3 has air permeability and water permeability, but even if the material itself does not have air permeability and water permeability, as illustrated in FIG.
It is carried out as a form in which air, moisture and fertilizer are passed inside and outside the seedling raising pot 3. The seedlings 4 are grown to a size suitable for planting, for example, by sowing seedlings or planting small seedlings directly in the seedling raising pot 3 using a Hedera helix as a service plant,
The whole seedling raising pot 3 is carried to the construction site. However,
The seedlings 4 may be cultivated in a normal vinyl pot or the like to a state suitable for planting, and may be replanted in the seedling pots 3 immediately before the planting work on the slope 2.

[0016] As shown in the figure, the seedling pot 3 is filled with a culture soil 5 and a fertilizer as necessary.
Maintain and promote the growth of seedlings 4. The seedling raising pots 3 are arranged at predetermined intervals, and are driven into the soil from above the sheet 1 laid on the ground 2 and fixed. The interval is
For example, by setting it to be about 30 cm square, the sheet 1 is fixed to the ground 2 so as not to shift in the seedling raising pot 3, and after a certain period of time, the roots and branches and leaves of the seedling 4 are stretched to cover the ground 2. Interval. However, the above-mentioned interval varies depending on the material and characteristics of the sheet 1, the inclination angle of the ground 2, the soil, the type of the seedling 4, and the like, and is not limited to about 30 cm. A method of fixing the seedling raising pot 3 is, for example, hitting the upper portion with a hammer or the like and driving the lower portion into the ground.

Plants suitable for planting on the slope 2 according to the present invention are not limited to the above-mentioned Hedera helix or tree seedlings, but may be other ground cover seedlings generally called so-called ground cover plants. It is suitably implemented also in planting. In the greening method according to the second aspect, the biodegradable sheet 1 is laid so as to cover the entire surface of the ground 2. The biodegradable sheet 1 is, for example, a nonwoven fabric sheet in which fibers composed of a biodegradable polymer described in Japanese Patent Application Laid-Open No. 8-193168 filed by Mitsui Toatsu Chemical Co., Ltd. It is preferably used.

According to the patent publication, the soil degradability (weight loss rate) of the biodegradable composition after 3 months is 35 to 53%.
However, the biodegradable polymer composition used for the non-woven fabric sheet 1 depends on conditions such as the season in which the seedlings 4 are planted, the soil at the place where the seedlings 4 are planted, the sunshine, etc., and the type and age of the seedlings to be planted. Use the one that gives the best biodegradation and disintegration rate. However, the sheet 1 is not limited to a nonwoven fabric, but may be a woven fabric.

The seedling raising pot 3 has a strength suitable for being driven into the ground and a sharp lower portion, and is preferably formed of a biodegradable plastic. The biodegradable plastic constituting the seedling raising pot 3 has an extremely low biodegradation rate or disintegration rate, and maintains the strength at which the seedling 4 can be driven into the soil even after growing to a size suitable for planting. Use those. Specifically, a composition in which the biodegradable polymer used in the nonwoven fabric sheet 1 is adjusted to have a very low biodegradation / disintegration rate so as to obtain sufficient strength over a long period of time is suitably used.

A seedling 4 is planted in the seedling raising pot 3. The seedlings 4 are sown in the seedling raising pot 3 or grown in a state where small seedlings are directly planted and grown to a size suitable for planting. However, seedling 4
Is cultivated in a normal plastic pot or the like to a state suitable for planting, and then planted in the seedling raising pot 3 immediately before planting on the slope 2. in this case,
The biodegradable plastic constituting the seedling raising pot 3 may have a relatively high biodegradation / disintegration rate.

The seedling raising pot 3 is driven into the soil from above the sheet 1 laid on the ground 2 at a predetermined interval. According to the present invention, since the ground 2 covered with the sheet 1 suppresses the growth and prosperity of weeds and trees, the seedlings 4 of the seedling raising pot 3 grow in an ideal environment without being disturbed by the weeds and trees. . Then, when the roots of the seedlings 4 are sufficiently rooted and prosperous on the ground, the sheet 1 and the seedling raising pot 3 biodegrade and return to the soil, and the greenery of the park and the like can be greened in a state close to the natural environment.

In the greening method according to the third aspect of the present invention, as shown in FIG. 1, the sheet 1 is laid so as to hang down the slope 2 and has a sharpness and strength suitable for driving into the ground. A seedling pot 3 having a lower part, formed of biodegradable plastic, and planted with seedlings is driven into the soil from above the sheet 1 at a predetermined interval and fixed. Therefore, the work of fixing the covering sheet 1 spread on the slope 2 and the work of planting the seedlings 4 can be temporarily performed at the same time, and the difficult work process on the inclined surface can be simplified and streamlined.

In the greening method according to the present invention, the seedlings 4 are cultivated in a vinyl pot or the like, carried into a construction site, and the empty seedling pots 3 are driven into the ground 2 before the same. 3 is characterized by a step of planting a seedling 4.

[0024]

[Effects of the present invention] By carrying out the revegetation method according to the present invention, the growth of weeds and bushes is suppressed by sheets, the growth of planted seedlings is promoted, and the seedlings are fully grown and strongly rooted. Can be. Accordingly, protection and stabilization are prevented by preventing erosion and collapsing due to natural light, wind and rain, etc. on not only flat park green spaces, but also slopes of roads, sloping slopes, etc. In particular, it is effective in greening slopes to maintain and improve the landscape. In addition, when the seedlings are sufficiently rooted and the branches and leaves are prosperous, the biodegradable covering sheet and the biodegradable seedling pot do not naturally decompose and return to the soil to pollute the environment, and are friendly to the natural environment. Furthermore, the work of spreading and fixing the covering sheet on the slope and the work of planting the seedlings can be performed at the same time in a transient manner. Play.
