On the sand layer, live sphagnum plants (about 8 g (dry base); i.e., about four times the amount of the live sphagnum plants employed in the above Example) were laid such that the plants overlapped with one another, and the container was left to stand under the same conditions. Also in this test, the sphagnum plants were found to grow to a certain degree. However, the growth level was clearly found to be low as compared with the case of the above Example.

  • the board was left to stand from June to September in a sunny room in Tokyo. During the course of the test, leaves and branches of the sphagnum plants grew, and, finally, the sphagnum plants covered substantially the entire surface of the lightweight orbicular board ( FIG. 27 ).
  • Shredded newspaper (180 g) and fine soil matter (500 g) [containing particulate cultivation soil dedicated for paddy rice seedling culture (400 g) and clay (100 g), the particulate cultivation soil having been finely granulated by means of a mixer to have a particle size comparable to that of a commercial non-particulate cultivation soil product] were incorporated into water (3 L), and the mixture was stirred and kneaded, to thereby prepare a precursor composition for a water-permeable composition (3 L).
  • the precursor composition was placed in a mold, and water was drained, to thereby produce a pumpkin-shaped molded product having a height of about 12 cm and a diameter at the bottom of about 15 cm and having a through-hole (diameter: about 5 cm) extending from top to bottom.
  • the mold was removed, the molded product was dried, to thereby prepare a support body.
  • a water-containing composition containing shredded paper as described above and dried sphagnum plants was packed into the lower part of the through-hole (from the bottom to the level of 7 cm).
