摘　　要：在柴达木地区建植草坪时,其出苗率与坪床覆盖度(单位面积垂直投影程度)呈正相关关系。本试验中坪床覆盖物为当地的枯草落叶,该设计为覆盖度为0%(即无覆盖)、50%和90%三个处理,结果表明,无覆盖物(0%)与覆盖度为50%和90%两处理相比较,分别为显著和极显著,证明苗床建植后其覆盖度越大出苗率越高。When we were planting lawn,its emergence rate and cover degree of turf seedbed were positive correlation in Chaidamu region. In this experiment,the turf bed cover was the local withered grass and defoliate leaves. The coverage was 0%,50% and,and 90% three treatments were established in this experiment. The results showed that coverage degree 0% and 50% two treatments were significant,overage degree 0% and90% two treatments were verysignificant. After the planting of the lawn seed bed that coverage more emergence rate higher.
