Abstract

PURPOSE:To allow easy planting with seed sowing work. CONSTITUTION:Each long stretching grass planted strip 1 is prepared which contains a base material for planting 4 wherein seeds 5 for grass are included, and a plurality of such strips are arranged alongside the contour lines substantially. The seeds 5 germinate and grow quickly and prevent erosion due to rainwater flowing down while creeping on the slope G. Moisture retaining belts 7 are arranged between the strips 1, and seeds 10 for tree are sowed on the slope G. Even though the seeds 10 germinate and grow slowly, they grow at a sound pitch because favorable conditions are arranged by the moisture retaining belts 7. The grass of quick growth grow rank in the form of belts, and trees grow in between, so that the trees grow without being pressed to enable covering the slope G with trees.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation and a vegetation method used for slope greening.

[0002]

2. Description of the Related Art Conventionally, the construction of a grassland plant based on a greening method has been performed on a degraded bare land, but the herbaceous plant has a weak soil conservation ability due to a shallow root system, or the like. It has been pointed out that the alien grass species, which are currently in widespread use, do not fit into the Japanese climate and decline year by year, and then become bare land again. ing.

In addition, when the woods are introduced by planting, the growth of the underground part is extremely poor, so that the trees do not extend to the outside of the planting hole, or the digging of the planting hole induces slipping of the surface layer. The slope may become unstable.

For this reason, it is desirable to construct the trees by planting them by sowing. However, the initial growth of the trees is slower than that of the grasses, and it takes about one month to germinate. However, even if it germinates, it often suffers damage such as erosion and dryness during that time, which hinders the formation of young trees. In addition, initial growth is extremely difficult, such as inability to withstand frost columns and freeze-drying in winter.

Further, among young trees, there are few fine roots crawling on the ground surface and the trees are susceptible to surface erosion, so a method of mixing and sowing with grasses has been proposed.

[0006]

However, even if the herbs and woods are easily mixed and sown, the woods are overwhelmed by the pressure of the early growth herbs and die. Even with herbs that have a slow initial growth and low plant height,
If the number of established herbs is large, they will be overwhelmed and die. If the seeds of herbs are reduced so that the trees are not pressured, the slopes are eroded and the seeds of the trees are washed away. For example, if the number of plants and the number of trees and the ratio of mixed seeding are not appropriate, the target forestation cannot be achieved.
For this purpose, various factors such as construction time, meteorological conditions, slope conditions, and soil cover thickness had to be examined and determined in detail.

An object of the present invention is to provide a vegetation method which can be easily made into a forest by a sowing process, a slope structure constituted by the method, and a vegetation body which can easily carry out the vegetation method. ..

[0008]

According to the first aspect of the invention, a plurality of long grass plant organisms filled with a vegetation base material mixed with seeds of herbs are arranged along substantially contour lines, and
A moisturizing band with moisturizing properties is placed between the plant and the plant,
In addition, seeds of woody plants will be sown.

According to the second aspect of the present invention, the slope is arranged such that a plurality of long grass plant organisms filled with a vegetation base material mixed with seeds of herbs are arranged along substantially contour lines. A moisturizing band having a moisturizing property is arranged between the grass plants and the seeds of woody plants are sown.

According to the third aspect of the present invention, a long plant vegetation body filled with a vegetation base material mixed with herbaceous seeds and a moisturizing zone having a moisturizing function are alternately assembled by a mooring body.

[0011]

According to the inventions of claims 1 to 3, since the plants are arranged substantially along the contour line with respect to the slope, the flow velocity of rainwater flowing down the slope is moderated to prevent erosion of the slope. To prevent. In addition, the seeds of herbs mixed in the vegetation base material germinate and grow early and grow in strips along the contour lines, further preventing soil erosion.

Further, the moisturizing body provides an environment in which seeds of woody plants are easily germinated and grown due to its moisturizing property. Therefore, seeds sown near the moisturizer and seeds washed near the moisturizer by rainwater grow slowly. In particular, since grasses grow in strips at the site where the plant life is arranged, the woods arranged between them grow well without being pressed by the grasses.

[0013]

According to the invention of claim 1, a plurality of long grass plant organisms filled with a vegetation base material mixed with herbaceous seeds are arranged along substantially contour lines, and A moisturizing zone with moisturizing property is placed between the seeds and seeds of woody plants are sown, so it is easy to construct without having to adjust the mixing amount and mixing ratio of seeds of grasses and woody plants one by one. be able to.

According to the second aspect of the present invention, a plurality of long grass plant organisms filled with a vegetation base material mixed with seeds of herbs are arranged along substantially contour lines and arranged. A moisturizing zone with moisturizing properties is placed between plants and seeds of woody plants are sown, so that slowly growing woody plants grow without being overwhelmed by fast growing herbs. Then, the slope can be made into a forest.

According to the third aspect of the invention, a long plant vegetation filled with a vegetation base material mixed with seeds of herbs and a moisturizing zone having a moisturizing function are alternately assembled by a mooring body. Therefore, the invention of claim 2 can be easily implemented.

[0016]

Embodiments of the present invention will be described below. (Example 1) Explaining in detail the example of construction in April, the planting organisms 1 are sequentially arranged in a straight line along the contour line on the slope G to be constructed, and fixed at appropriate positions with the anchors 2 to obtain planting vegetation. The body 1 is arranged in a straight line without bending (see FIG. 2A).

As shown in FIG. 3, this plant body 1 is filled with a vegetation base material 4 which is composed of vermiculite as a main material and a super-slow-acting fertilizer mixed in a tubular body 3 made of paper-coated frosted cloth whose both sides are closed. It has a length of 2 m and a thickness of 5 cm. In addition, this vegetation base material 4 is mixed with seeds 5 of grass species such as grass seeds and Japanese pampas grass that are vigorously germinating and growing, and germinates in about one week after the construction. It is designed to promote growth. In addition, the interval between the grass-planting organisms 1 and 1 is such that even if the seed 5 germinates, the herbaceous surface G
An interval of 50 to 100 cm that grows in a streak shape without covering the whole is set, and this is sequentially repeated to apply to the entire slope G.

Next, a moisturizing band 7 having a thickness of 2 to 3 cm is arranged in parallel between the parallel fixed grass plant 1 and the grass plant 1 and fixed and fixed by an anchor 8 (see FIG. 2 (b)). ). The moisturizing band 7 may be a straw rope, a straw bundle, or a bag-shaped band containing bark or vermiculite in a bag, as long as it has moisturizing properties and promotes germination and growth of seeds of woody plants. .. In particular, a straw rope having a thickness of 2 to 3 cm is particularly desirable because it has both heat retention and heat retention necessary for growing woody plants and can be easily fixed to the slope G almost endlessly.
The moisturizing zone 7 is about 1 between the rows of the plant organisms 1 fixed on the slope G.
It is desirable to arrange a plurality of rows so as to be 5 to 20 cm, and in this embodiment, they are arranged in two rows.

Next, the entire slope G is covered and fixed with a vegetation net 9 (see FIG. 2 (c)).
The base material 11 mixed with 0 is sprayed to a thickness of 1 to 7 cm so that the vegetation net 9 is hidden, and the construction is completed. As is well known, the base material 11 is a mixture of bark compost and a curing stabilizer, which is hard to run off by rainwater. The covering with the vegetation net 9 is for preventing the base material 11 from collapsing, and is not always necessary depending on the slope G to be constructed, such as the slope G having a gentle slope.

In the sowing work constructed according to this example,
As shown in FIG. 1, since the grass-planting organism 1 has a convex shape on the slope G, the flow velocity of rainwater or the like is moderated and erosion of the slope G is prevented. Approximately one week after construction, seeds of herbs germinate and grow to a height of 50 to 100 cm before winter. Therefore, on the slope G, herbaceous plants grow in strips along the grass-planting organism 1, and soil erosion and runoff due to rainwater or the like are further prevented. In addition,
In this embodiment, since the vegetation net 9 covers the base material 11, the base material 11 is prevented from collapsing.

Incidentally, after about one month, the seeds 10 of woody plants,
Germinates in the sprayed area. In particular, rainwater flowing down the slope G is weakened by the planting organism 1, so that some seeds 10 of woody plants are washed away, but they are caught by the auxiliary material 7 and germinated at the site of the moisturizer 7. It will be easier. Then, as shown in FIG. 4, even in the case of the woody plant T that grows only about 10 cm even before the winter, the site between the planting plants 1 in which the herbaceous S is not overgrown, such as the seeded site and the moisturizing site. The small seedlings of woody plant T that germinated in the zone 7 can grow without being pressed. In particular, since the moisturizing zone 7 has a moisturizing property, the woody species T germinated in the vicinity of the moisturizing zone 7 can grow smoothly even when the growing conditions of the woody species T are adjusted and there is sunshine.

(Embodiment 2) Embodiment 2 is an example in which a living organism 21 is prepared in advance so that the seeding work shown in Embodiment 1 can be performed more easily. This plant 21
As shown in FIG. 5, a plurality of 2 m wide planting organisms 1 are bound together by a mooring cord 22 as a mooring body at 1 m intervals,
It is long in the vertical direction. Further, two moisturizing bands 7 are bundled in parallel between the bound grass plant organisms 1 and 1 at equal intervals so that the grass plant organism 1 is held without being bent. ing.

As described above, the living organism 21 is made long by the mooring string 22, so that it can be stored and transported in a rolled state and is easy to handle. In addition, at the time of construction, if one end is fixed by an anchor or the like on the upper side of the slope G to be constructed and deployed toward the lower side of the slope G, FIG.
It can be easily installed in the state shown in.

If necessary, the vegetation body 21 is covered with the vegetation net 9, and then the base material 11 mixed with the seeds 10 of woody plants is sprayed and applied. Therefore, the construction can be made very easy.

Although the example in which the mooring string 22 is used as the mooring body is shown, the present invention is not limited to the string and may be connected to the net. In this case, use this net as slope G
If the seeds of woody plants can be immediately sprayed by unfolding and fixing the seeds, the work can be further facilitated.

(Embodiment 3) In this embodiment 3, in order to facilitate the seeding work described in Embodiment 1, as shown in FIG. 6, the moisturizing zone 7 is bound to the vegetation net 9 in advance to form the vegetation net 31. Here is an example. In this third embodiment, if the grass-planting organism 1 is fixed in the state shown in FIG. 2A, and the slope G is covered and fixed by the vegetation net 31 in this state, the state shown in FIG. 2C is obtained. You can And from above, woody seeds 10
The construction can be completed by spraying the base material 11 mixed with.

In Examples 1 to 3, the grass plant 1 was set to have a length of 2 m and a thickness of 5 cm, but these may have a thickness of 2 to 10 cm depending on the situation such as the slope G. The length can be appropriately selected such as 1 m, and the vegetation base material 4 can also be appropriately selected according to the kind of herbaceous matter. You can
