摘　　要：研究根瘤菌根部定殖对于揭示根瘤菌在根圈的微生态学特征、提高其根际适应性和增产效果的稳定性具有十分重要的意义。本文从根部定殖概念及根瘤菌在土壤中的定殖能力对其竞争结瘤能力的影响着手,介绍了根瘤菌根部定殖的研究概况。其中重点阐述了基因标记技术研究根瘤菌定殖群体动态的进展及影响接种根瘤菌根部定殖的生物学和非生物学因素。In the study to reveal micro-ecological characteristics of Rhizobium and to improve its adaptability to rhizosphere and its stability in increasing production of leguminous crops, it is of significant importance to study root colonization ofRhizobium. A review was presented, starting with the concept of root colonization and colonization ability of Rhizobium, and their effects on competitive nodulation of Rhizobium. And then introduction was given to development of the gene-labeling technique in the study on dynamics of Rhtzobium population in root colonization, and biological and non-biological factors affecting root colonization.
