Medium selection and compounding of environmental eco-engineering through making use of life rubbish to produce carpet turf

Abstract

Abstract: Through making use of life rubbish as medium and choosing several materials with high feasibillity as compound materials to produce carpet turf, the medium selection and compounding were carried out,and the growth effect of several kinds of turfgrass on each compound medium, its pH value and water stress function were also studied.Sawdust could raise the drought resistant capactity of turfgrass by strengthening the water retaining capacity of medium,and promote turfgrass growth.Plant ash showed a strong basicity,and when it made up 25% of medium,the pH value of the medium could be over 9.Fine river sand could improve the ventilating capacity of medium,but if mixed too much,it would decrease its nutritional level. It is suggested that the performance of compound mediums differed greatly with compound materials.Synthesizing each index studied showed that among all compounding mediums sawdust had a significantly positive effect,and had a broad application value.
