Abstract

In order to accelerate the restoration and utilization of mine wasteland, this paper describes an optimization study on substrate materials. The optimization was based on nine well-planned orthogonal experiments (OA9 matrix). The experimental materials were tailings, turfy soil and sawdust, and the experimental plant was festuca arundinacea. Two contrast tests was carried out in the purpose of finding out the most appropriate substrate for plants growth. Based on the results of the range analysis and analysis of variance (ANOVA), conclusion was obtained that the optimized ratio of the substrate materials is Vtailings: Vturfy soil: Vsawdust =3:1:1. The physicochemical properties of the optimized substrate include pH, bulk density, porosity and water-holding capacity, the value is 6.3, 1.0, 59.9% and 32.7% respectively. Festuca arundinacea grew well in this substrate, emergence rate was 62%, survival rate was 52%, aboveground biomass was 19.71g and plant height was 25.54cm
