| 摘 要： | 采用细菌16S rRNA基因高变区和真菌ITS区的Illumina MiSeq高通量测序技术结合分子生态网络方法，分别测定了5种施肥处理（常量化肥，NPK；化肥减量，NPKR；化肥减量配施秸秆，NPKRS；化肥减量配施有机肥，NPKRO；化肥减量配施有机肥和秸秆，NPKROS）土壤中细菌和真菌的群落组成，构建可视化分子生态网络，并针对土壤有机质（soil organic matter,SOM）进行相关性网络分析，探究化肥减量和有机替代下土壤微生物群落分子生态网络及有机质相关性网络的变化特征。结果表明，化肥减量和有机替代显著提高了土壤SOM含量。与NPK处理相比，在细菌分子生态网络中，化肥减量和有机替代处理均增加了网络节点数和边数，降低了平均路径长度；在真菌分子生态网络中，NPKR处理提高了网络节点数和边数；有机替代处理增加了平均路径长度，降低了平均聚类系数；化肥减量和有机替代处理下与土壤SOM含量显著正相关的细菌菌群占比增加，真菌菌群占比降低。综上所述，化肥减量和有机替代能提高细菌分子生态网络规模和物种间传递物质、能量和信息的效率。化肥减量能提高真菌分子生态网络规模和群落互作，有机替代...
