MANUFACTURING METHOD OF GREENING BASE MATERIAL FOR SLOPED FACE GREENING WORK

摘要

To provide, in a manufacturing method of a greening base material for a sloped face greening work, a fermentation fertilizer obtained by using sewage sludge as a fermentation promoting material, kneading unused wood chips and bark, and performing aerobic fermentation treatment, and a greening base material using the fermentation fertilizer as a plant growth base in a sloped face greening work.SOLUTION: A fermentation fertilizer is manufactured by: kneading sewage sludge with unused wood chips and bark; throwing the kneaded product into a fermentation tank comprising a rotary type fermentation device; fermenting the product aerobically for about two weeks by ventilation and turn back; sieving fermented compost whose moisture content is adjusted to be substantially 40 to 45% by fermentation reaction heat by a screen with 20 mm mesh, to adjust to a size equal to or smaller than 20 mm; and storing and making the compost stand in a flexible container bag with gas permeability until fermentation reaction heat settles after 4 to 6 months of aging period.SELECTED DRAWING: Figure 1
