格氏栲幼苗根系性状的生长权衡对氮磷添加的响应
Growth Trade-offs of Root Traits in Castanopsis kawakamii Seedlings in Response to Nitrogen and Phosphorus Addition
[目的]由于我国亚热带地区长期受氮沉降影响,导致植物生长主要受到磷限制。为理解格氏栲幼苗在磷限制严重的亚热带地区的地下生长权衡策略,探究格氏幼苗根系性状对氮磷添加的响应,以期为格氏栲种群的可持续发展提供理论参考。[方法]以格氏栲(Castanopsis kawakamii)幼苗为研究对象,依据当地氮磷水平设置氮(低氮(N1)、中氮(N2)、高氮(N3))、磷(低磷(P1)、中磷(P2)、高磷(P3)),并依据氮磷比设置交互试验,即N0P0、N1P…查看全部>>
[Objective]Due to the long-term impact of nitrogen deposition in subtropical regions of China,plant growth is mainly limited by phosphorus.To understand the underground growth trade-off strategy of Castanopsis kawakamii seedlings in subtropical areas with severe phosphorus limitations,and to explore the response of root traits of Castanopsis kawakamii seedlings to nitrogen and phosphorus addition,in order to provide theoretical reference for the sustainable …查看全部>>
