Abstract:: Silt solidification as planting soil is an important way to solve dredging a large amount of silt from the lake tunnel project.In the paper，the effect of different solidifying agent content treatments on physical and chemical properties of lake silt and growth of turfgrass were analyzed.The results showed that there was no significant effect of different solidifying agent content on soil bulk density and organic matter，but the total salt content and pH value showed an increasing trend.The soil water content decreased significantly after adding solidifying agent，and compared with the silt set for 10 days，the soil water content were decreased by 30.5%-20.2% after 3%-8% solidifying agent added(T2-T7).From the growth of Festuca elata，Lolium perenne，the emergence rates，plant height and NDVI of the trufgrass added solidifying agent were higher than those without silt solidification and 4% solidifying agent(T3) was the most significant.
