In order to study the low control and lightweight roof planting system, six kinds of drainage-block were examined(Drainage-block, Egg-mat, P.P-tusupet SO920, Eco-mat, World drainage F, Drainage adiabatic-blocks). The peat moss with perlite(1:1, v/v) of a 10cm-depth media was used followed by Sedum sarmentosum planted at intervals of 10cm. Most of all management did not applied. The result was as follows;
The World drainage F was light the most, the maximum storage of water(L) is that Drainage-block per 1㎡ 302L. Per 1㎡ price of drainage-blocks the World drainage F was the cheapest and construction costs were relatively minimal. The 6 controls did not exhibit a large difference. In 15~20days, the covering weight of the Drainage-block and Egg-mat which were fallen quite a bit was high but the covering rate seemed to almost same, chlorophyll contents is also same conclusion with covering weight.
During the summer(July, August. September), the ground temperature of each drainage compared in 8℃ that was evenly low, the Drainage adiabatic-blocks filled the role of let high temperature down. During the dry period(after two weeks), the growing condition of Egg-mat, Eco-mat and Drainage adiabatic-blocks were better than before, the condition of controled composition is good although the composition was differently transferred. All controled conditions was not bad even in rainy period.
