Effects of Media Kinds and Container Forms for Urban Agriculture on the Growth Characteristics of Several Herbaceous and Woody Plants

초록

This study was conducted to examine effects of media kinds and container forms for urban agriculture on the growth of herbaceous andwoody plants that could be used in construction of urban greenery and landscape gardens. The main objective of the study was to investigatethe most efficient culture soil and container form for four herbaceous and one woody plant species. In this study, five different specieswere examined on three different media kinds [horticultural substrate (HS), decomposed granite (DG), and horticultural substrate +decomposed granite (HS + DG)] with two different container forms [vinyl pot (Ø7.5 cm) and plug tray (20 cells)]. The results indicatedthat pH values of media of HS and HS + DG were 5.8 and 5.9, respectively while DG was 6.5. HS had the highest electrical conductivitywith 0.90 dS･m-1while HS + DG and DG had 0.39 and 0.08 dS･m-1, respectively. Especially, most of the species experimented on HStended to have the highest growth rate in the plant height, the root length, the number of leaves and fresh biomass weight compared toother soil kinds (P<0.05). The growth rate on HS + DG was much higher than DG. Therefore, our results support that HS + DG couldbe possible to replace with HS. In addition, there had no differences on growth rates between container forms (P>0.05). The use of plugtray could be more applicable than the use of vinyl pot containers, considering growth rates of plants and convenient of shipment on plantproduction.
