[Diagram 2] FIG. 2 is a diagram showing the configuration of a vegetation base material according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] First, a growth-promoting base material 10 according to an embodiment of the present invention will be described with reference to Fig. 1. The growth-promoting base material 10 according to this embodiment is used as a material for a vegetation substrate 20 used in a vegetation substrate spraying method. The vegetation substrate spraying method is a type of slope protection work in which slopes formed by cutting mountain soil or filling the soil are greened to prevent erosion and collapse of the slopes.

[0017] 1, the growth-promoting base material 10 according to this embodiment is a mixture of water purification generated soil 1, bark compost 2, and a promoter 3 that promotes the water absorption of wood chips 12 used in the vegetation substrate 20, which is enclosed in a bag B. In this embodiment, 50 liters of water purification generated soil 1, 50 liters of bark compost 2, and 0.1 kg of the promoter 3 are mixed in 100 liters of the growth-promoting base material 10.

[0018] The water purification waste soil 1 is made by concentrating and dehydrating mud generated during the process of making tap water, compressing it into plates, and then crushing it. In this embodiment, by effectively utilizing the water purification waste soil 1, it is possible to reduce waste disposal and the environmental burden. The bark compost 2 is an organic fertilizer made by fermenting bark.

[0019] 2, the vegetation substrate 20 according to this embodiment is composed of a mixture of a growth-promoting base material 10, plant seeds 11, wood chips 12, fertilizer 13, and an erosion inhibitor 14. The vegetation substrate 20 thus composed is sprayed onto the slope by a mortar sprayer.

[0020] In the vegetation substrate 20 according to this embodiment, a domestic native species (such as turf grass) that is a deer dislike plant is used as the plant that becomes the seed 11. By using the seeds 11 of a domestic native species instead of an invasive alien herbaceous plant, it is possible to preserve the natural vegetation that grows naturally in the area. Furthermore, since the seeds 11 in this embodiment do not use alien herbaceous plants that serve as food for deer, it is possible to suppress the spread of deer damage, which is becoming more serious in mountainous and hilly areas. Furthermore, early greening is possible by increasing the sowing rate of the seeds 11.

[0021] It is also preferable that the type of plant can be changed for each target vegetation area for the seeds 11. In other words, it is preferable to adopt seeds of local greening plants as the seeds 11. For example, in areas such as natural parks where the greening purpose is to conserve biodiversity, it is more preferable to determine a seed mix that takes into consideration the local ecosystem.

[0022] The wood chips 12 are obtained by crushing wood from felled trees to a size that can pass through a 1.5-inch screen (specifically, a size of about 20 mm to 30 mm). The accelerator 3 suppresses the water repellency caused by the wood chips 12 being raw chips, and improves the water absorption ability. In this embodiment, using felled wood for the wood chips 12 can contribute to suppressing the emission of greenhouse gases that cause global warming.

[0023] The fertilizer 13 is an advanced compound fertilizer with an NPK of 15-15-15. The erosion inhibitor 14 prevents the seeds 11, the wood chips 12, and the fertilizer 13 from eroding or drying out.

[0024] As described above, the growth-promoting base material 10 according to this embodiment and the vegetation substrate 20 using the growth-promoting base material 10 can be used to realize "local production for local consumption of greenery" by using the seeds 11 of local greening plants as materials. This makes it possible to find value as a new local resource and to create new businesses by effectively utilizing abandoned farmland in mountainous areas where aging and depopulation are serious problems.
