Abstract: In order to reduce the dependence of soilless culture of flowers on peat and increase the recycling rate of green waste, we made a research to assess the feasibility of green waste composting replacing the peat as growing media. By using peat and green waste as raw materials, we utilized six kinds of growing media，including peat(Y), carbonized green waste (TY), composting (DZ), peat+carbonized green waste(Y+TY), peat+composting(Y+DZ), peat+carbonized green waste+composting(Y+TY+DZ) to cultivate Calathca rotundifola cv. Fasciata. Through measuring and analyzing ten growth indexes, ie total fresh weight, fresh root weight, fresh leaf weight, total dry weight, dry root weight, dry leaf weight, total crown, branching number, plant height and root length, we could get the results of positive effects of six kinds of growing media on the cultivation of C. rotundifola cv. Fasciata and the rank order was Y+DZY+TYDZYY+TY+DZTY. It can be seen that green waste composting undertaken a certain treatment can replace all or part of the original imported peat to cultivate C. rotundifola cv. Fasciata, and three of the six treatments were better than the original peat. The growth of C. rotundifola cv. Fasciata was promoted after using three kinds of growing media. Thus, the green waste could be treated as an excellent growing media to the soilless culture of C. rotundifola cv. Fasciata.
