Description

[Detailed description of the invention] The present invention relates to a method for constructing cut grass.

Cut grass is wild or cultivated grass that has been cut along with its underground rhizomes. Generally, in order to install cut grass on the soil surface, the soil surface in the area to be constructed must be fertilized and cured. This is done by pasting the grass and applying soil between the cut grass.

However, this method has the disadvantage that it takes a long time for the entire surface to become green because the seeds that germinate from the top soil are the underground rhizomes of cut grass. Furthermore, when applying cut grass, it is necessary to cure it by applying fertilizer, but if there is variation in the application of fertilizer, there is a drawback that the grass may wither due to lack of fertilizer or concentration problems in some areas. Furthermore, it has the disadvantage that it is not easy to confirm whether or not fertilization has been applied, and construction inspection cannot be performed reliably.

The present invention was developed as a result of various studies in order to eliminate the above-mentioned drawbacks of the conventional methods.Before installing cut grass, a vegetation belt containing seeds and an appropriate amount of fertilizer, etc. is spread on the soil surface. By pasting the cut grass and applying top soil between the cut grass, you can reliably prevent poor fertilization or forgetting to fertilize, and also allow seeds to germinate in the top soil area, resulting in early full-scale greening. The purpose of the present invention is to provide a method of constructing cut grass in a manner that allows the user to carry out the work.

Next, the construction method of the present invention will be explained with reference to drawings that are one embodiment.

In the drawing, 1 is a soil surface on which cut grass 2 is to be pasted, and first, a vegetation belt 3 is spread over the entire surface of the soil surface 1.

This vegetation zone 3 includes, for example, grass seeds 6 of the same type as the cut grass 2 and fertilizer 7, and in some cases soil conditioner 8 and fertilizer 7 between two sheets 4 and 5 of water-decomposable paper or the like. Water-absorbing resins (for example, Sumikagel, registered trademark, Sumitomo Chemical Co., Ltd., Sunwet, etc.)
Sanyo Chemical Industries, Ltd., etc.) etc. are sealed between two sheets using a heat seal 9 to prevent movement.

Then, the cut grass 2 is pasted, for example, in a checkered pattern on the vegetation zone 3, and top soil 10 is applied between the cut grass 2.

As mentioned above, since the cut grass 2 is pasted onto the soil surface 1 through the vegetation zone 3, the sheets 4 and 5 decompose due to moisture in the soil or rainwater, and the vegetation zone 3
The fertilizer 7 inside allows the cut grass 2 to grow well, take root well, and have sufficient underground rhizome growth.

In addition, since the grass seeds 6 germinate in the top layer 10 as well, in conjunction with the germination from the underground rhizomes, the top layer 10 portion becomes green at an early stage. Note that if the cut grass 2 itself dies partially, greening of the grass seed 6 that germinates in this area will not be inhibited.

If a water retaining material and a soil improving material are also mixed into the vegetation zone 3, sufficient greening can be achieved even in areas where the growth environment for grass is poor. In addition, vegetation zone 3 is the actual Kosho 51-
As shown in Japanese Patent No. 38283, if a net is provided on the upper surface of the sheet 4, when planting vegetation on a slope, the net can prevent the top soil 10 or the cut grass 2 from shifting.

Further, the vegetation zone 3 is, for example,
Of course, as shown in Publication No. 37282, straw or the like may be provided on the upper surface of the sheet 4.
Furthermore, the cut grass 2 may be covered with joints. In this case, as described above, since the grass in the joint area has good germination, the cut grass 2 can be pasted at greater intervals than before, and the amount of cut grass used can be reduced.

As is clear from the above explanation, according to the cut grass construction method of the present invention, there is a vegetation zone containing seeds, fertilizers, etc. under the cut grass, so if the vegetation zone is constructed, it will automatically As a result, an appropriate amount of fertilizer is applied almost uniformly, which not only makes it easy to confirm fertilization, but also prevents problems such as insufficient fertilizer and impaired fertilizer concentration caused by variations in fertilization.

In addition, the top soil area can be greened more quickly than in conventional methods, as germination occurs from the underground rhizomes of the cut grass and from the vegetation zone.

In addition, if soil improvement materials etc. in the vegetation zone are mixed,
Cut grass can be installed even in areas with poor growth conditions for plants.
