Function annotation and analysis of different microorganism species in T0-20 and T20-40.

(A) Cooccurrence network diagram of the interaction in different microorganism (B) relative abundance of functional annotations and (C) heat map and clustering tree in microorganism species at different layers of soils. The cooccurrence network diagram was drawn based on the correlation coefficient of top 100 microbial genera. The top 35 functions and their abundance information in each sample were used to draw a heat map, and then clustered from the level of functional differences. The data was analyzed based on amplicon sequencing of soil samples, and each soil sample includes triplicates.
