저관리 경량형 옥상녹화에 적합한 Sedum속 식물을 비교 실험하고자 하였다. 저배수판에 피트모스1: 펄라이트1(v/v)를 혼합한 배지를 10cm 깊이로 채운후 10cm 간격으로 9가지 Sedum속 식물(돌나물, 땅채송화, 바위채송화, 큰꿩의비름, 기린초, 섬기린초, 가는잎기린초, S. ‘Spurium’, S. ‘Diffusum’)를 식재하여 생육특성 및 관상가치를 평가하였다. 큰꿩의비름, 기린초, 섬기린초, 가는잎기린초 순으로 초장이 컸고, 돌나물, 땅채송화, 바위채송화, S. ‘Spurium’, S. ‘Diffusum’ 이 비슷하였다. 초폭도 유사한 결과가 나왔다. 돌나물, 땅채송화, 큰꿩의비름, 기린초, 섬기린초, 가는잎기린초는 정식 30일 후 90%이상 피복되었으나 땅채송화는 장마철이후 65%까지 떨어졌으며, 돌나물은 낮고 빠르게 피복되었고, 큰꿩의비름, 기린초, 섬기리초, 가는잎기린초는 풍성하고 빠르게 피복되었다. 엽록소 함량은 땅채송화, 바위채송화, S. ‘Diffusum’이 낮았고, 다른 식물은 거의 유사했다. 여름동안(7, 8, 9월) 각 식물의 지온은 콘크리트 바닥에 비해 평균 7oC가량 낮았다. 돌나물은 60일 이후에는 100% 피복되고 엉켜서 생육조사를 할 수 없었고, 땅채송화는 병해를 입으면 급격히 줄어들었다가 15일 이후에 빠르게 회복되었다. 한편 바위채송화는 생육상태가 그다지 좋지 않았다. S. ‘Spurium’, S. ‘Diffusum’은 피복속도는 느렸으나 생육상태가 좋았고, 큰꿩의비름은, 분홍꽃, 기린초, 섬기린초, 가는잎기린초는 노랑꽃이 피어 관상가치가 높았다.

It was intended to have comparative study of Genus Sedum plants that are appropriate to low management and light weight rooftop greening. A drainage-block was filled with a medium with mixture of peat moss 1 and perlite 1 (1:1 v/v) in 10cm-depth and 9 Sedums plants including Sedum. sarmentosum, S. oryzifolium, S. polytrichoides, S. spectabile, S. kamtschaticum, S. takesimense, S. aizoom, S. ‘Spurium’, and S. ‘Diffusum’ were planted. No management was made and the result was as follows: Plant heights were in the decreasing order of S. spectabile, S. kamtschaticum, S. takesimense, and S. aizoom, and S. sarmentosum, S. oryzifolium, S. polytrichoides, S. ‘Spurium’, and S. ‘Diffusum’ showed similar plant heights. In terms of plant width, the result was similar. Although S. sarmentosum, S. oryzifolium, S. spectabile, S. kamtschaticum, S. takesimense, and S. aizoom were covered by 90% or more by day-30; however, covering of S. oryzifolium was decreased to 60% after rainy season; S. sarmentosum was covered rapidly; and S. spectabile, S. kamtschaticum, S. takesimense, and S. aizoom were fruitfully and rapidly covered. In terms of chlorophyl contents, S. oryzifolium, S. polytrichoides, and S. ‘Diffusum’ showed low contents and other showed similar contents. Ground temperatures of each plant were lower than concrete ground by Genus Sedums. 7oC in average during summer (July, August, and September). S. sarmentosum was 100% covered and was tangled after 60 days with impossible growth survey; S. oryzifolium was decreased when suffered from blight and harmful insects and was rapidly recovered within fifteen days. Meanwhile, growth of S. polytrichoides was not so good. S. ‘Spurium’ and S. ‘Diffusum’ showed good growth speed and although their covering speed was slow; S. spectabile blossomed in pink, S. kamtschaticum, S. takesimense, and S. aizoom blossomed in yellow with high ornamental value.
