Use of mulberry-soybean intercropping in salt-alkali soil impacts the diversity of the soil bacterial community.

Li X, Sun M, Zhang H, Xu N, Sun G - Microb Biotechnol (2016)

Bottom Line: Most of Actinobacteria and Chloroflexi were found in intercropping samples, while Acidobacteria and Proteobacteria were present at a higher percentage in monoculture samples.The plant diversity of aboveground and microbial diversity of belowground was linked and soil pH seemed to influence the bacterial community.Finally, the specific plant species was the major factor that determined the bacterial community in the salt-alkali soils.

Canonical correspondence analysis (CCA) for soil bacterial community and soil environmental variables. Arrows indicated the direction and magnitude of measurable variables associated with bacterial community structures. Each triangle represents a different bacterial phyla or proteobacterial class.

mbt212342-fig-0007: Canonical correspondence analysis (CCA) for soil bacterial community and soil environmental variables. Arrows indicated the direction and magnitude of measurable variables associated with bacterial community structures. Each triangle represents a different bacterial phyla or proteobacterial class.

Mentions: To investigate relationships between soil microbial community composition and measured environmental variables, different bacterial phyla and proteobacterial classes were analysed using canonical correspondence analysis (CCA) (Fig. 7). The influence of the environmental parameter on the CCA bioplot is indicated by arrows in which lengths are proportional to their importance (Liu et al., 2009). pH had the longest arrow, indicating that it was most important in influencing the bacterial community. Conductivity was also significantly linked to bacterial phyla variance in CCA. With the exception of Nitrospirae, the relative abundances of all of bacterial phyla and classes positively correlated with soil pH and conductivity. Water content (WC) was also negatively correlated with Chloroflexi, Candidatedivision TM7 and Planctomycetes.
