Abstract
To investigate the effects of rhizobia,the catalase,urease and invertase of rhizosphere soil at seedling,flowering,seed filling,mature stage of soybean,as well as yield and its related characters at mature stage of soybean were determined.The results showed that rhizosphere soil enzyme were increased at first and then decreased with the soybean growth period.The activities of three enzyme were increased by applying rhizobia and promoting bacteria agent.Compared with control,rhizobia and rhizobia plus promoting bacteria agent treatment increased soybean seed yield by 30.23% and 11.08%,respectively.
