| 英文摘要 | Acetylene reduction activities (ARAs) of soils and rice plants during rice-growing season were monitored in temperate region in northeast China. This activity was significantly higher in rhizosphere soil than that in inter-row soil after rice seedlings were transplanted. The ARA was high for most of growing season, suggesting that the native N-2-fixing bacteria responded to rice roots very quickly. Sixteen strains of free-living N-2-fixing bacteria were isolated from three different soils. The ARAs of these strains were correlated with the averaged soil ARAs, suggesting that the isolated strains were likely the active flora responsive to rice roots. The strains were inoculated by soaking seedling roots into the liquid culture for 2 h, and the seedlings were transplanted into pots. Most strains tested did not show any growth-promoting effects except Azotobacter armeniacus and Azotobacter nigricans, which showed growth-promoting effects only at late rice growth stage and only when inoculated in combination but not separately. Present data indicated the promising future applications of these two strains in combination in the region, but further research is needed to understand the underlying mechanisms. |
