Effects of different waste soilless medium on Bermudagrass (Cynodon dactylon) sod production

An experiment was carried out determine the effect of coal cinder, sawdust, municipal sludge, waste compost and mushroom soil on the sod quality character, operating costs and environment benefit of sowing Bermudagrass (Cynodon dactylon) named Tiantang 328. The results of this study indicated that Bermudagrass obviously reduced the Cu and Zn content, and the sod color, cover and aboveground biomass in municipal sludge treatments was better or significantly higher than that in other four treatments (P 0.05).The total biomass and root biomass in the municipal sludge and coal cinder were significantly lower or higher than that in other treatments (P0.05). The sod freshness was not significant among five treatments (P0.05). The comprehensive estimation showed that five waster soilless medium in the order: municipal sludge（municipal sludge=0.885）mushroom(mushroom=0.674)sawdust (sawdus =0.598)waste compost(waste compost=0.550)coal cinder(coal cinder=0.543), suggesting that the municipal sludge was the best soilless medium of the bermudagrass sod.
