Abstract:

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.
