摘要/Abstract

摘要： 根际微环境是构建植物与土壤交流沟通的桥梁，也是植物遭受胁迫时优先作出响应的区域。植物根系作为根际的主要调控者，根构型和根系分泌物种类、数量的改变均可对根际微生物和土壤动物种群分布及其结构造成影响。然而，土壤动物的扰动、微生物的分解作用也可改善根际土壤特性，提高植物抗逆性及养分利用效率，从而促进植物根系生长。可见，植物根系根际动物根际微生物之间存在复杂的互作关系。本文从根际内、外微环境出发，分析了根际外植物根系对微环境的物理和化学扰动、根际内植物根系与微生物的互作扰动、根际内植物根系和土壤动物的物理扰动、以植物根系分泌物为介质的化学扰动等方面研究进展，在此基础上，论述了根际微环境主要影响因子之间的互作机制，并对该领域的研究方向进行了展望。

Abstract: Rhizosphere micro-environment is the bridge of communication between plant and soil, and the priority area that responds to the environmental stress. Changes in root architecture, type and quantity of exudates may impact rhizosphere microorganisms and soil fauna structure and diversity, as the roots are main regulators of rhizosphere. However, there are complicated interactions between plant roots, microorganisms and soil animals in the rhizosphere. Soil animals’ disturbance and microbial decomposition can improve rhizosphere soil properties, and enhance plant stress and nutrient use efficiency, thereby promoting the growth of plant roots. Based on the studies of the physical and chemical disturbances of external microenvironment of root rhizosphere, interactive disturbance of roots and microbes of internal rhizosphere, physical disturbance of roots and soil animals, chemical disturbances with root exudates as the medium, we clarified the interaction mechanisms of disturbance in internal and external environment of rhizosphere, and made prospects for further research in this field.
