亚热带常绿阔叶林林下灌木光合荧光特性对长期氮磷添加的响应特征
Effects of Nitrogen and Phosphorus Additions on Soil Organic Carbon Storage and its Components in a Subtropical Forest
[目的]探究长期氮(N)、磷(P)添加后亚热带常绿阔叶林中林下灌木的光合特性及荧光参数的变化方式及响应特征,为植物光合生理特性应对长期 N 沉降这一全球性气候变化提供基础数据。[方法]本研究基于长达 11 年的N及N+P添加野外试验,通过野外活体测定红楠(Machilus thunbergii)、杜茎山(Maesa japonica)、山矾(Symplocos sumuntia)、朱砂根(Ardisia crenata)4 种林下优势灌木的光合特…查看全部>>
[Objective]To understand how photosynthetic properties and fluorescence parameters of understorey shrubs in subtropical broadleaved evergreen forests respond to long-term nitrogen(N)and phosphorus(P)additions,and to provide basic data on plant photosynthetic physiological properties in response to global climate change with long-term N deposition.[Method]In this study,based on an 11-year field experiment with N and N+P additions,the photosynthetic characteri…查看全部>>
