초록

For evaluating the effect of various organic fertilizer ratios on the Spiraea×bumalda ‘Gold Mound’ growth, a container green wall system experiment was conducted in a greenhouse at Konkuk university. The experimental planting grounds were prepared with different organic fertilizer ratios (A_1L_0, A_8L_1, A_4L_1 A_2L_1 and A_1L_1) and with drought tolerance and an ornamental value Spiraea×bumalda ‘Gold Mound’ was planted. The change in soil moisture contents, plant height, number of branches, number of dead leafs, number of leaf, number of shoots, length of node, length of leaf, width of leaf, root-collar caliper, chlorophyll contents and survival rate were investigated from April to Jun 2010.
1. The result of soil moisture contents was analyzed with weight unit in the container green wall system during the dry summer season. The soil moisture contents were significantly enhanced in the container green wall system in increasing order as the amount of fertilizer level increased A_1L_1> A_2L_1> A_4L_1> A_8L_1> A_1L_0 .
2. Compared to the control treatment (amended soil with 100% + organic fertilizer 0%) application, the highest plant growth was observed in the treatment of A_2L_1(amended soil with 67% + organic fertilizer 13%) application. However, the differences between the organic fertilizer ratio treatments of A_1L_1, A_4L_1, A_8L_1, and the A_1L_0 organic fertilizer application were mostly not significant.
3. The survival rate increased with the increasing application of organic fertilizer, but in the control treatment (amended soil with 100% + organic fertilizer 0%) application all the plants died.
Experimental results from the presented study clearly demonstrated that the organic fertilizer improved the survival rate more than the Spiraea×bumalda ‘Gold Mound’ growth at different levels of organic fertilizers. This strain can be utilized as a plant growth application in living wall systems during the dry summer season. Therefore, Spiraea×bumalda ‘Gold Mound’ is expected to be a highly valuable shrub for the green wall system if it should be considered in integration with stormwater retention or as a soil conditioner for increasing soil water contents in planting ground.
