Microbial functional diversity in rhizosphere and non-rhizosphere soil of different dominant species in a vegetation concrete slope

To investigate the effects of different dominant species on microbial functional diversity vegetation concrete substrates, rhizosphere and non-rhizosphere soils three (Pennisetum alopecuroides (PA), Arthraxon hispidus (AH) Pueraria lobata (PL)) were studied using Biolog-Eco method at Xiangjiaba Hydropower Station. The results showed that activity indices in soil plants significantly higher than those AH, as well PL, a high level. carbon sources predominantly used by microbes carbohydrates, amino acids polymers, while carboxylic acids, polymers. governing elements source metabolic features community moisture content (WC), organic matter (OM), total nitrogen (TN), potential hydrogen (pH), (MBC), (MBN) phosphorus (MBP). Based thorough examination these aspects, it was concluded had altered structure substrate, perhaps improving overall activity. A. with adaptability should be prioritized regeneration slopes.
