Abstract:: This article uses round brown nitrogen as the starting strain, which is treated with ultraviolet mutagneity and obtained two maximum positive variable plants. The nitrogen fixation capacity increases by 112.47 % and 110.79 % compared with the starting strains; the nitrogen fixation capacity is increased by 458.65 respectively from the departure strains, respectively. %.
