摘　　要：In rice field, especially in the fertilized field the combined nitrogen content is rather high. It is well known that the nitrogen compounds, particularly NH4^+ inhibits the nitrogenase activity- of diazotrophs. So, the enhancement of nitrogen fixation ability of diazotrophs in the presence of ammonia by means of genetic manipulation will be of importance for agricultural use.
