夏季干旱期新老毛竹水分传输和水分竞争研究
[目的]毛竹(Phyllostachys heterocycla)作为一种分布广泛的高大散生木本竹种,具有重要的生态和经济价值。近年来夏季极端高温干旱事件频发,常导致当年生毛竹大量死亡,为毛竹林生产力恢复和灾后演替埋下重大隐患。为深入理解毛竹在新老龄级上的死亡差异机理,本研究聚焦于两个主要研究内容:1)夏季极端干旱进程中毛竹新老竹的水分利用和水力性状响应差异;2)以及新老竹因生理整合而对竹鞭系统的水分共享与竞争。[方法]在 2020 年夏季 7-…查看全部>>
[Objective]As a giant woody bamboo species distributing widely,Moso bamboo(Phyllostachys edulis)has high ecological and economic values to the local communities.Extreme events with high temperature and intensive drought occurred frequently in recent years,which had led to significantly higher mortality rate of newly sprouted culms,posing a threat to the post-disaster recovery and succession of Moso bamboo forests.To deeply understand the mechanism of differe…查看全部>>
