摘要
The effect of pH on the nodulation of Sinorhizobium fredii and Bradyrhizobium japonicum was examined by analy- zing the indigent soybean rhizobia,predominant indigent rhizobia,and specific rhizobia,respectively.The results showed that very acid and very alkaline environment could retard the nodulation and inhibit the growth of the rhizobia.Sinorhizohium fredii could endure environment more strongly than Bradyrhizobium japonicum,and had a high competitive nodulation capacity.Bradyhizobium japonicum could endure acid environment more strongly than Sinorhizobium fredii.In very acid and very alkaline environment,the nodulation capacity of S.fredii and B.japonicum was mainly determined by their physiological characteristics.
