The purpose of the study was to demonstrate the feasibility of bran to be the matrix of soilless-cultured lawn through measuring physiochemical indexes of matured bran and biological indexes of lawn.A three-level bran maturing experiment with four levels of fertilization was carried out.The biological indexes of ryegrass lawn were measured 30 days after seedling emergence.Results show that the physical and chemical indexes of matured bran meet the basic requirements of lawn cultivation and it can be used as a lawn matrix.The addition of sludge for maturing is more effective than the addition of sugar and check

which can significantly increase ryegrass growth rate.When the rate of seedling emergence is higher than 60%

the lawn is coiled.The study provides some basic data applied to soil and water conservation and slope protection.
