摘　　要：生物固氮是一个全球性的战略课题,而共生固氮又是生物固氮的主体部分,因此研究豆科植物-根瘤菌共生固氮体系(根瘤)的固氮潜力具有重要意义。本文介绍了大量营养元素和微量营养元素对根瘤固氮潜力的影响的研究现状和主要进展,阐述了各营养元素影响根瘤固氮潜力的机制,并对根瘤固氮潜力研究的前景进行了展望。Because the biological nitrogen fixation is a global strategic problem, and symbiotic nitrogen fixation is the main part of biological nitrogen fixation. Thus it is very important to research the nitrogen fixation potential between legume and Rhizobium. In the article, the statue about the effect of macro-elements and micro-elements on the nitrogen fixation potential of root nodule and its main progresses were summarized. At the same time, the mechanism about the effect of nutrient elements on nitrogen fixation potential was discussed, and the prospect of symbiotic nitrogen fixation was described.
