On the other hand, it is preferably about 90 to 90% by mass and about 30 to 90% by mass. If the water content is too low, the paper crushing operation when using crushed paper becomes difficult, and it becomes difficult to sufficiently knead the crushed paper with the fine soil material. If the water content is too high, the weight of the precursor composition becomes too heavy, which not only places an excessive burden on the preparation operation of the composition, but also wastes water resources.

- the content ratio of the moss plant in the water-permeable composition may be set high.
- the moss plant may be contained so as to be about 2 to 15 times (mass ratio) the content of the water-permeable composition other than the moss plant. If the content of the moss plant is less than twice the content of the non-moss plant in the permeable composition, the elements (paper fiber, soil fine matter, and dried sphagnum) other than the moss plant will The rate of covering the surface increases, making it difficult for moss plants to fully photosynthesize. When the content of the bryophyte exceeds 15 times, the fixing power of the bryophyte in the water-permeable composition is reduced. There is a tendency to be too weak.
- the surface of the molded water-permeable composition is formed while the content of the bryophyte in the water-permeable composition is less than twice (mass ratio), preferably 0.1 to 1 times.
- a nearby moss plant is exposed by various exposure means.
- the exposure means 2) is extremely advantageous in that moss plants can be efficiently exposed and dust is not generated as in the exposure step. is there.
- the precursor composition to be brought into contact with the water flow is in a "pre-solidified state" containing water, so that the composition usually breaks down due to the water flow.
- the moss plant existing in the vicinity of the surface of the precursor composition in contact with the water flow can prevent the entire composition from collapsing by trapping the water flow. For this reason, only the fine soil material and ground paper of the precursor composition on the very surface are washed and washed by contact with the water stream, so that the desired exposed state of the moss plant can be realized very easily.
- the shape of the water-permeable composition to be molded is a shape approximate to a sphere

In other words, if greenish coloring is observed, it is determined that the growth point is secured, and if green color is lost, the growth point is substantially lost. It is possible to determine that there is.

- the portion including the growing point of the growing sphagnum moss is substantially exposed from the dried sphagnum moss. This requires that the growth point of the growing sphagnum moss be in a state that does not submerge in the specific sphagnum cultivation base. In this state, the growth point of the growing sphagnum moss is substantially exposed to the dried sphagnum moss. This makes it easy to maintain.
- substantially exposed refers to a state where the growing sphagnum moss is exposed in a convex shape from the dried sphagnum moss, for example, provided in the dried sphagnum moss.
- the sphagnum growing portion is shorter than the depth of the concave portion, and as a result, the tip of the growing sphagnum stays in this concave portion, but the growing portion of the sphagnum sprout grows due to the growth of the sphagnum sprout. This includes the case where a space exposed outside the fixed object is secured.
- the effect of this filtration is to use dried sphagnum moss that has a long overall length (including the length of one unit of sphagnum moss in the longitudinal direction as well as the length of multiple units of dried sphagnum moss connected in the longitudinal direction). It can be improved.
