摘　　要：以‘兰引Ⅲ号’结缕草为试材,进行无土栽培试验,研究了4种不同的隔离层(遮阳网、无纺布、地膜、砖块)材料对‘兰引Ⅲ号’结缕草草皮质量的影响;通过定期测定草坪盖度、密度、颜色及成坪后的草皮强度,以便筛选出适合的无土草皮生产的隔离材料。结果表明:建植70d后遮阳网隔离层草皮的盖度为92.78%、100cm2密度为81.34枝、色泽为6.67,均高于其余隔离层材料,生长过程整体表现为遮阳网>砖块>无纺布>地膜;砖块的草皮强度为5.98kg,显著高于其余3种隔离层材料,但砖块隔离层与遮阳网隔离层相比建设成本太大。综合考虑,认为遮阳网隔离层比较适合‘兰引Ⅲ号’结缕草无土草皮的生产,而地膜的排水透气能力较差,不适宜作为‘兰引Ⅲ号’结缕草无土草皮生产的隔离层材料。Taking Zoysia japonicacv.‘Lanyin No.Ⅲ＇as test materials,a soilless cultivation experiment was conducted to study the influence of the four different isolation layers（sun-shade net,non-woven,mulch,bricks）materials on Zoysia japonicacv.‘Lanyin No.Ⅲ＇soilless sod.The grass coverage,density,colour and sod intensity were measured throughout the experiment to screen out suitable insulation materials for‘Lanyin No.Ⅲ＇soilless sod production.The results showed that the coverage of sunshade net was 92.78%,density was 81.34branch·（100cm2）-1,colour was 6.67 after 70days of planting,which were higher than the other insulation materials.The rank of the four different isolation layers was sunshade net〉brick〉non-woven〉mulch during the experiment.Although the sod strength of bricks was 5.98 kg,significantly higher than the other insulation materials,its construction cost was higher than sun-shade net.Considering of the above results of the four different isolation layers it was concluded that sun-shade net was better as insulation layer for Zoysia japonicacv.‘Lanyin No.Ⅲ＇soilless sod production whereas mulch was not suitable as insulation layer due to its poor drainage ability.
