Abstract: Fly ash was mixed separately with sewage sludge and distillers' grains in a ratio of 4∶1 to get new reclaiming substrates, the growth of Medicago sativa L., Cotton, Festuca arundinacea, Poa pratensis L. in the substrates and the main characteristics of the substrates were studied by the pot experiments. The results showed that the plants could grow in the substrates, chlorophyll content of the plant in the substrates all exceeded that of the plant in the soil, few change was observed with the organic matter content in the substrates, available nutrient content reduced because of the leaching by irrigation and rainwater. But they still kept high contents compared with their contents in soil. The salt content reduced obviously in the substrates, the contents of As, Pb, Cd, Cu, Zn except Cd were lower than those of the Soil Environment Quality Standards Ⅱ. In conclusion, the substrates could basically meet the plant growth. But it had better to plant the non-edible plants.
