The present invention relates to a vegetation block for greening of a slope, using waste as a raw material to save expenses to treat the waste, greening a slope for a long time through smooth growth of a seed and strong rooting of a root, and also stably reinforcing the slope； and a slope greening reinforcing method using the same. According to the present invention, the vegetation block comprises: a greening block body formed with a mixture of 55 to 60 wt% of clay and organic soil, 8 to 12 wt% of lake and river deposit soil, 8 to 12 wt% of a thinning material, 8 to 12 wt% of food waste, and 9 to 12 wt% of fertilizer, and having a vertically penetrated seed hole； and a support plate having a plate shape with one or more holes, laterally inserted and arranged inside the greening block body to section a seed part of an upper part and a rooting part of a lower part, so as to support the seed implanted in the seed part. Moreover, the method comprises: a first step of forming a block implanting groove on a slope； and a second step of implanting the vegetation block for greening of a slope in the block implanting groove formed in the first step, wherein the vegetation block comprises a greening block body formed with a mixture of 55 to 60 wt% of clay and organic soil, 8 to 12 wt% of lake and river deposit soil, 8 to 12 wt% of a thinning material, 8 to 12 wt% of food waste, and 9 to 12 wt% of fertilizer, and having the vertically penetrated seed hole, and the support plate having the plate shape with one or more holes, laterally inserted and arranged inside the greening block body to section the seed part of the upper part and the rooting part of the lower part, so as to support the seed implanted in the seed part.본 발명은 사면 녹화용 식생 블록 및 이를 이용한 사면 녹화 보강 공법에 관한 것으로, 폐기물을 재료로 하여 폐기물의 처리를 위한 비용을 절감하고 종자의 원활한 발육과 뿌리의 견고한 활착을 통해 사면을 오래동안 녹화함과 더불어 안정적으로 보강하는 것을 목적으로 한다.본 발명에 의한 사면 녹화용 식생 블록은, 점토 및 유기질 토 55~60중량%, 호수 및 하천 퇴적토 8~12중량%, 간벌재 8~12중량%, 음식물 쓰레기 8~12중량%, 비료 9~12중량%의 혼합으로
