得ることができる。In the slope greening structure thus formed, it is not necessary to dry or compost the plant material, so that the plant material generated at the site can be chipped and used as it is. Therefore, by mixing seaweed minerals and sludge fermenting fertilizer with raw wood or wood chips that are close to the state of raw wood, it is suitable for greening by giving the nutritional value necessary for composting, and an extremely simple construction method is used. Therefore, even if the cost of chipping the plant material is added, the construction can be performed at a cost close to the conventional method. In this case, there is also a cost advantage in that the use of plant material generated on site eliminates the need for yard or industrial waste treatment. In addition, the seaweed residue used is conventionally discarded as it is a by-product generated in the process of producing agar, and even if the seaweed residue after extracting the agar components in this way, nutrients such as minerals are also discarded. Since it contains a large amount of water and has viscosity, it promotes the activity of microorganisms by its nutrients and promotes the composting of wood chips, and the water retention of the plant growth base 12 on the slope 11, which is a slope due to its water retention. Can be ensured, and its viscosity can prevent the plant growth base 12 from scattering and flowing out. In addition, since the effective microorganisms supplied by the obscure manure and the like are utilized in natural farming methods or natural agriculture, they are suitable for nature and play a role of keeping the slope 11 vegetative and stable. Then, the plant growth base 12 incorporates the advantages of natural farming or natural agriculture by utilizing blurring manure, and if the plant material generated at the site is used, it prevents the generation of waste materials at the site, and the food by using the seaweed residue. The waste can be effectively used and the waste from the sewage project can be utilized by using the sludge fermenting fertilizer. This revegetation method can be extremely effective as a recycling system.
