PURPOSE: To obtain the subject structure, equipped with a stringy structural body composed of a large- and a small-diameter hollow fiber units prepared by knitting a fiber bundle into a hollow braid form, provided with nursery soil in one of inner spaces of the small-diameter part and seeds in the other, having lawn on walls and capable of improving beautiful appearance of buildings.

CONSTITUTION: A stringy structure 1 for rearing plants is equipped with a stringy structural body 1 of a double structure composed of an inner hollow fiber unit 2, prepared by knitting a fiber bundle into a hollow braid form and having a relatively small diameter and an outer hollow fiber unit 3 of the same structure, arranged on the outside of the aforementioned inner hollow fiber unit 2 and having a relatively large diameter. An inner space 4 in the interior of the inner hollow fiber unit 2 and an outer space 5 between the inner hollow fiber unit 2 and the outer hollow fiber unit 3 are formed. At least nursery soil 6 of the nursery soil 6 and a fertilizer 7 is arranged in the inner space 4 which is one of the spaces between the inner hollow fiber unit 2 having the small diameter and the outer hollow fiber unit 3 having the large diameter and seeds 8 of plants are placed in the other outer space 5. Thereby, the objective stringy structure capable of penetrating water to the whole structure by feeding the water from one end, naturally germinating seeds and providing lawn, etc., on walls, etc., of buildings is obtained.
