望天树人工林根际土壤微生物群落随林龄变化特征及其对磷限制的影响
Variation characteristics of microbial community in rhizosphere soil of Parashorea chinensis plantations with stand age and its effect on phosphorus limitation
[目的]本研究旨在分析亚热带龙脑香科濒危树种人工林根际土壤养分现状和微生物群落特征,明确林龄对土壤真菌和细菌群落结构及功能的影响,以及根际微生物在磷素转化过程中发挥的关键作用,并揭示微生物群落与磷素有效性和磷限制的相关关系。[方法]以 6 个林龄的望天树人工纯林为研究对象,采集根际土壤,通过分析微生物群落多样性与磷组分的动态转化特征,揭示它们之间的相互影响及随年龄的变异特征。[结果](1)6 个林龄的林地根际土壤处于强酸性和缺磷状态,Fe3+对磷…查看全部>>
[Objective]The aim of this study was to analyze the current status of rhizosphere soil nutrients and microbial community characteristics in plantations of endangered tree species of Dipterocarpaceae in the subtropics,to clarify the effects of stand age on the structure and function of soil fungal and bacterial communities,and the key role played by rhizosphere microorganisms in the phosphorus(P)conversion process,and to reveal the correlation between microbi…查看全部>>
