摘要： 本试验以青绿苔草(Carex breviculmis)为试验材料，研究了4类7种规格的隔离层(200目尼龙网、300目尼龙网、80g无纺布、120g无纺布、100g土工布、150g土工布、棉布)对青绿苔草无土草皮质量的影响。结果表明，隔离层显著影响草皮质量，200目尼龙网、300目尼龙网、80g无纺布、120g无纺布在起卷难易度与起卷完整性之间均表现显著差异(P＜0.05)，棉布、100g土工布、150g土工布间差异不显著；灰色关联度分析法综合评价得分排名由高到低为：300目尼龙网、200目尼龙网、120g无纺布、80g无纺布、棉布、150g土工布、100g土工布。300目尼龙网作为隔离层时青绿苔草无土草皮的密度、质地、地下部生物量等指标均较高，且综合评分最高，最适宜作为青绿苔草无土草皮生产的隔离层，200目尼龙网、120g无纺布也可以作为隔离层，棉布、土工布效果较差不适宜做隔离层。

Abstract: This paper was based on Carex breviculmis as the test material and studied the effects of four types and seven specifications of isolation layers (200 mesh nylon net,300 mesh nylon net,80g non-woven fabric,120g non-woven fabric,100g geotextile,150g geotextile and cotton cloth) on the quality of Carex breviculmis soilless turf. The results showed that the isolation layer significantly affected the turf quality. There were significant differences in the difficulty and integrity of reeling between 200 mesh nylon net,300 mesh nylon net,80g non-woven fabric,and 120g non-woven fabric (P<0.05),but there was no significant difference among cotton cloth,100g geotextile,and 150g geotextile.From high to low,the total evaluation scores of Grey Relational Analysis (GRA) method are:300 mesh nylon net,200 mesh nylon net,120g non-woven fabric,80g non-woven fabric,cotton cloth,150g geotextile,100g geotextile. When the isolation layer used a 300 mesh nylon net,the density,texture,underground biomass,and other green carex soilless turf had all the high indicators and achieved the highest total scores. It is the most suitable isolation layer for producing green carex soilless turf. The 200 mesh nylon net and 120g non-woven fabric could also be the isolation layer. The cotton cloth and geotextile have poor effects and are unsuitable for the isolation layer
