Abstract Under greenhouse condition,common bean(Phaseolus vulgaris Linn.)‘Taiguowujindidou’was sowed in pots to estimate the effects of different inoculation ways on bean’s plant growth,nodulation,total pod weight of single plant,AM colonization rate,nitrogen and phosphorus contents and absorption of bean plant. When seeding,the beans were inoculated with Glomus mosseae(AM),rhizobia(RH),Glomus mosseae and
rhizobia(AM+RH),and the beans without inoculation were taken as the control(CK). The results indicated that dual inoculation(AM+RH) could obviously promote the plant growth of beans. Compared with inoculation with Glomus mosseae(AM),rhizobia(RH)and none(CK),the plant total dry weight of the beans inoculated with AM+RH increased 34.3%, 82.3% and 57.9%, respectively. Besides,the dual inoculation could increase the total pod weight of single plant and promote bean’s absorption of nitrogen and phosphorus. The phosphorus absorption of total plant was increased by 42.1%, 314.8% and 325.4%, respectively than that by AM,RH and CK. While,the nitrogen absorption of total plant was increased by 36.8%,45.1% and 43.4%,respectively than that by AM,RH and CK. The Glomus mosseae and rhizobia had synergistic effect on common bean,and the Glomus mosseae could effectively improve bean’s resistance,reduce the yellow leaf ratio,and thus decrease the occurrence of diseases.
