く要求されるようになってきた。However, as described above, when vegetation is carried out using a vegetation material storage bag containing vegetation materials such as plant seeds and fertilizer, vegetation is uniformly spread over the entire slope. It was difficult to apply. That is, the vegetation material storage bag portion made of the insoluble sheet, which is a hardly decomposable sheet, has a problem that the roots of the plant do not pass through and the plant does not take root, so that only that portion remains without vegetation. For this reason, it was more conspicuous than other vegetation parts and exhibited an artificial and unnatural landscape. In particular, in recent years, vegetation in a natural state has been desired, and vegetation without a sense of incongruity has been strongly demanded.

The vegetation condition was greatly influenced by the weather conditions because of melting and vegetation material flowing out in large quantities. In particular, a large amount of rainfall immediately after being placed on a slope or the like, or on a steep slope or the like, most of the vegetation material flows out at once, so that vegetation could not be uniformly applied to the entire slope.
