摘要
对上海师范大学奉贤校区5个代表性草坪上细叶小羽藓进行了调查。结果发现,细叶小羽藓发生平均盖度达50%以上,严重段达76%。细叶小羽藓多呈集群分布,在调查区域内,细叶小羽藓均在3.6～4.0 m、7.2～9.6 m的范围内出现明显斑块。说明细叶小羽藓斑块的出现与其入侵年限和入侵地生境异质性相关,细叶小羽藓的入侵会抑制草坪草的生长。
5 representative Haplocladium microphyllum lawnweeds in Fengxian campus of Shanghai Normal University were investigated. The result showed that average coverage rate of 1t. microphyllum in lawn is 50%, 76% appeared in some serious lot. In the surveying area,H, microphyllum usually distributed in a isolating cluster fashion and presented obvious patches in the range of 3.4 - 4.0 m and 7.2 - 9.6 m. It indicated that patches emergence of H. microphyllum might be associated with the invasion years and habitat heterogeneity of the invasion site, and the invasion of H. microphyllum could inhibit growth of the turfgrass.
