（特願平１−241330号）。Conventional technology Conventionally, when planting roots of planted seedlings for greening vegetation on rocks such as flat ground and slopes, it is necessary to hold and fix the seedlings, make relatively large holes in hard rocks, The roots of the seedlings were put together with fertile high quality soil to stabilize. Such a holding and fixing method has a problem that labor and labor of drilling a large hole in hard rock are required, and it is not easy to stabilize the wooden part vertically by keeping it in the large hole. I was In order to solve such problems, the applicant has previously developed a method for stabilizing the roots of seedlings using anchor pins (Japanese Patent Application No. Hei 1-241330).

という問題を有していた。"Problems to be Solved by the Invention" In the technology developed earlier by the applicant, after holding the roots of the seedlings to be vegetated with anchor pins as described above,
Nutrients are applied and soil is sprayed to cover the soil. However, when using such a construction method, especially when the place where vegetation greening is performed is on an inclined surface, the vertical stability of the seedlings is excellent. However, there is a problem that the roots of the seedlings do not easily settle on the bedrock as expected, so that the seedlings cannot be sufficiently cured, and the initial purpose of greening vegetation cannot be achieved.
「課題を解決するための手段」 そこで、本発明は上記のような問題点を解消せんとす

Then, high quality soil and compost are mixed and filled so as to surround the roots, and a seed source is attached to the surface. In addition to fixing the circular bag made of coarse bags, the flow of iodine filled around the root inside the circular bag is suppressed, and not only the root vegetation is ensured, but also the circular bag is It is easy to absorb moisture and nutrients, grows a seed source where good quality soil and fertilizer in the coarse bag adhere to the surface, plants the grass, colors the greens around the plants and gives a beautiful feeling, In addition to pressing the annular bag into the coarse bag of the annular bag to hold the annular bag, it is also excellent in water retention and ensures root vegetation.
In addition, the coarse bag of the annular bag body rots with the passage of time to form compost, which helps to cure the roots.
