摘　　要：以生活垃圾为基质 ,选用几种可行性强的材料为配材 ,进行了生活垃圾生产地毯式草皮基质的选配 ,通过几种草坪草在各选配基质上的生长效应 ,及对选配基质的 pH值及水分胁迫性能进行了研究 .结果表明 ,不同选配基质对草坪草的生长效应差异较大 ,锯木屑可通过增强基质的保水性能而提高草坪草的抗干旱胁迫能力 ,并能促进草坪草的生长 ,草木灰显较强的碱性 ,当其占基质 2 5 %时 ,则 pH值可达 9以上 ,细河沙可改善基质的通透性 ,但配施量过多就会降低基质营养水平 ,说明配材不同 ,选配的基质性能也有较大的差别 .综合各项研究指标 ,则配材锯木屑在生活垃圾生产地毯式草皮的基质配制中 ,正向效应明显 ,应用价值较大 .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.
