摘要： 于播种前，以5×108 CFU/mL浓度的PGPR菌株B9601Y2, FZB42, B2 和 B9拌种蚕豆，在全生育期土壤重度干旱条件下，与清水拌种相比，它们均能提早出苗，促进幼苗生长，增加植株地上和地下重量与荚果数，B9601Y2，FZB42，B2和B9菌株分别增加蚕豆株荚数0.65个、0.50个、0.05个和0.33个，有效荚数0.68个、0.53个、0.08个、0.28个，果荚重4.56 g、3.36 g、2.13 g、0.36 g，株粒数1.18粒、1.55粒、0.80粒、0.15粒，百粒重5.28 g，5.75 g，3.72 g，2.50 g，豆粒产量14.49%，12.04%，6.28%，2.21%。

Abstract: Four PGPR strains, B9601Y2, FZB42, B2 and B9 were used for dressing seeds of broad bean at the concentration of 5×108 CFU/mL before seeding. Under serious drought during whole growth period, all these strains could enhance the growth of broad bean in comparison with negative control: obviously earlier seed germination, higher plant at seedling stage, increasing weight of above and underground parts and more pod number. The pods after dressing seeds of broad bean with B9601Y2, FZB42, B2 and B9 were increased by 0.65, 0.50, 0.05 and 0.33, the fruiting pods per plant were 0.68, 0.53, 0.08 and 0.28, the pod weights were 4.56 g, 3.36 g, 2.13 g and 0.36 g, the seeds per plant were 1.18, 1.55, 0.80 and 0.15 g, the weights per 100seeds were 5.28 g，5.75 g, 3.72 g and 2.50 g, the grain yield of broad bean were 14.49%, 12.04%, 6.28% and 2.21%, respectively.
