凋落物、根系和菌根输入对木荷恢复林地土壤微生物群落结构的影响
Effects of litter,root and mycorrhiza input on soil microbial community structure in Schima superba restoration forest
[目的]阐明森林生态系统碳输入对土壤微生物群落结构的影响,为红壤退化地植被恢复过程中土壤肥力演变及生态系统恢复的微生物驱动机制提供理论依据。[方法]本文以亚热带红壤侵蚀退化地恢复形成的木荷纯林为研究对象,设置5种输入处理,即对照(CT)、菌根(M)、根系+菌根(RM)、凋落物+根系+菌根(LRM)和凋落物加倍+根系+菌根(DLRM),利用Illumina HiSeq技术研究了不同有机碳输入对木荷纯林土壤微生物群落结构的影响。[结果]各有机碳输入处…查看全部>>
[Objective]The effects of different organic carbon inputs on soil microbial community structure were studied to provide a theoretical basis for soil fertility evolution and ecosystem restoration in the process of vegetation restoration in degraded red soil.[Method]The Schima superba pure forest recovered from eroded and degraded red soil in the subtropical region was taken as the research object.Five inptut treatments were set as follows:control treatment(CT…查看全部>>
