Abstract
- We employed a comparative study to examine the effects of tree species transition on soil microbial biomass, community composition and enzymes activities under Cunninghamia lanceolata (Lamb.) Hook, Eucalyptus grandis and a N-fixing species, Acacia melanoxylon in subtropical China. Results showed that the effect of tree species on soil microbial community and enzymes activities was significant only in the 0-10 cm soil layer. Reforestation with N-fixing species A. melanoxylon on the C. lanceolata harvest site significantly increased the total phospholipid fatty acid (PLFA), fungal PLFAs, Gram-positive bacterial PLFAs, Gram-negative bacterial PLFAs and actinomycetes biomasses in the 0-10 cm soil layer. The principal component analysis (PCA) showed that the soil microbial community composition in A. melanoxylon soil differed significantly from that in C. lanceolata and E. grandis soils. N-fixing species (A. melanoxylon) significantly enhanced the percent abundance of Gram-positive bacteria, Gram-negative bacteria and actinomycetes. Activities of cellobiohydrolase, N-acetyl-β-d-glucosaminidase and acid phosphatase were significantly higher under A. melanoxylon than under C. lanceolata and E. grandis plantations. Our results suggested that reforestation with N-fixing species, A. melanoxylon on C. lanceolata harvest site could increase soil microbial biomass, enzyme activities and soil organic matter content.
