| 摘 要： | 2000—2005年的试验研究表明:“黑土滩”上建植的垂穗披碱草人工植被在自然演替状态下短期内就会发生严重退化,而人工调控可使人工植被的盖度、高度和地上生物量保持在90%、60cm和5 630kg/hm2以上,因此,施肥、灭杂、灭鼠等人工调控措施是“黑土型”退化草地垂穗披碱草人工草地持续利用的关键。

| Abstract: | A study for six years had been conducted in an Elymus natus sown grassland which was "black-soil-type"degraded grassland.The results indicated that the Elymus natus sown grassland vegetation planted in "black-soil-type" degraded grassland would degraded seriously under natural succession condition within short-term,however,artificial control measure including fertilizing,Weeding,killing mouse et al.could keep cover of vegetation in 90%,height in 60cm and aboveground biomass in 5 630kg/hm~2.Therefore,the artificial control mesure such as fertilizing,weeding and killing mouse and so on were pivotal factors of sustainable utilization for Elymus natus sown grassland built in "black-soil-type"degraded grassland. |
