根系分泌物在植物根系-土壤-微生物互作过程及其生态反馈机制中发挥重要作用。在植物根际复杂网络互作过程中,
根系分泌物被认为是“根际对话”的媒介, 其在调控植物适应微生境、缓解根际养分竞争及构建根际微生物群落结构方面
意义重大。该文结合国内外该领域主要研究成果, 综述了根系分泌物对植物生长、土壤微生物特性及土壤养分循环的影响,
并展望了未来根系分泌物的研究方向。

Root exudates play an important role in root-soil-microorganism interactions and ecological feedback mecha-
nisms. Root exudates are considered as the medium of “rhizosphere dialogue” in the process of complex plant rhizo-
sphere network interaction, with great impact in regulating plant adaptation to microhabitats, thus alleviating rhizosphere
nutrient competition and constructing rhizosphere microbial community structure. Here, we review the recent advances on
the effects of root exudates on plant growth, soil microbial characteristics such as soil enzymes, microbial biomass, and
microbial community, and soil nutrient circulation. We also propose the important directions and contents of future re-
search on root exudates.
