摘 要：为了探索氮添加对土壤和根际微生物群落结构的影响,笔者归纳了近十年来与微生物群落结构相关的国内外文献数据。在前人已有研究基础上,详细总结了氮沉降对土壤理化性质(土壤pH值、土壤全氮(TN)、土壤全碳(TC))、土壤微生物生物量、土壤微生物、根际微生物群落结构等指标的影响,并对上述现象做出合理分析。笔者指出氮沉降增加会在一定程度上对土壤和根际微生物群落结构有显著的促进作用,但是当氮沉降达到一定阈值时,会显著抑制土壤和根际微生物群落结构的增长。作者通过研究发现目前在模拟试验中有关氮沉降对土壤和根际微生物群落结构的影响,大部分都仅仅是短期的生物模拟化学实验,并且大多数人都在谈论模拟实验的现象。因此,今后在设计模拟试验过程时,还应进一步延长模拟时间,对引起试验响应变化的主要机制进行更深入的探讨,以期能更好的为进一步深入研究有关氮沉降的增加是否对土壤和根际微生物群落结构的具体影响能提供试验参考依据。In order to explore the effects of nitrogen addition on soil and rhizosphere microbial community structure, the author summarizes the domestic and foreign literature data related to microbial community structure in the past decade. The effects of nitrogen sedimentation on soil physico-chemical properties (soil pH, soil total nitrogen (TN), soil total carbon (TC)), soil microbial biomass, soil microorganisms, rhizosphere microbial community structure and other indicators were summarized in detail, and the above phenomena were reasonably analyzed. The author points out that the increase in nitrogen sedimentation will have a significant role in promoting soil and rhizosphere microbial community structure to a certain extent, but when nitrogen sedimentation reaches a certain threshold, it will significantly inhibit the growth of soil and rhizosphere microbial community structure. The authors found that most of the current effects of nitrogen deposition on soil and rhizosphere microbial community structure in simulation experiments are only short-term biomimetic chemistry experiments, and most people talk about the phenomena of simulated experiments. Therefore, I believe that in the future, when designing the simulation test process, the simulation time should be further extended, and the main mechanisms that cause changes in the response of the test should be further explored, in order to better provide a reference for further in-depth study of whether the increase in nitrogen deposition has a specific impact on soil and rhizosphere microbial community structure.
