Fig. 7From: Screening of high-efficiency nitrogen-fixing bacteria from the traditional Chinese medicine plant Astragalus mongolicus and its effect on plant growth promotion and bacterial communities in the rhizosphereEffects of bacterial fertilizer on biomass and effective components of A. mongolicus. A is the effect on the plant height, (B) is the effect on the root length, (C) is the effect on the dry weight of the aerial part of A. mongolicus, (D) is the effect on the dry weight of the root, E is the effect on the content of astragalus flavone, (F) is the effect on the content of astragaloside, (G) is the effect on the content of astragalus polysaccharide. *, **, and *** indicate significant differences between bacterial fertilization and control at p < 0.05, p < 0.01, and p < 0.001, respectivelyBack to article page
