摘要: 大气中的氮沉降会导致土壤中N积累量增加，直接影响土壤碳氮循环。植物根际分泌物能够深刻地改变土壤微生物群落并影响其N的转化。探究根际分泌物对氮沉降的响应以及在土壤碳氮循环中的作用机制成为植物地下碳氮循环的关注重点。本文主要从根际分泌物的C输入、化学组分、化学计量比和根际分泌物–根际微生物机制几个方面，对根际分泌物和根际微生物的研究动态进行综述，重点论述目前氮沉降背景下根系分泌物的重点研究方向与根际微生物的相互作用等方面的研究情况与进展，并对当前根际分泌物研究中存在的问题进行探讨，以及展望未来的发展趋势。
Abstract: Nitrogen deposition in the atmosphere will increase the amount of N accumulation in the soil, which directly affects the soil carbon and nitrogen cycle. Plant root exudates can profoundly change the soil microbial community and affect its N transformation. Exploring the response of root exudates to nitrogen deposition and the mechanism of action in the soil carbon and nitrogen cycle has become the focus of the plant’s underground carbon and nitrogen cycle. This article mainly focuses on the research trends of root exudates and rhizosphere microorganisms in rhizosphere ecology from the aspects of C input, chemical composition, stoichiometric ratio and root exudates-rhizosphere microbe mechanism. This review focuses on the current research status and progress on the interaction between root exudates and rhizosphere microorganisms under the background of nitrogen deposition. It also discusses the existing problems in the current research on root exudates, and looks forward to the future development trend.
