为研究土壤细菌群落对不同农艺措施的响应,揭示土壤细菌群落结构与土壤环境因子的相互关系,以紫泥田水稻土为研究对象,设置石灰、商品有机肥、土壤调理剂3个处理,对土壤细菌16S rRNA基因测序,分析不同处理对细菌群落组成和多样性的影响。结果表明:与对照相比,有机肥和调理剂处理提高了土壤细菌α多样性指数,而石灰处理降低了土壤细菌α多样性指数;石灰和有机肥处理的细菌α多样性显著高于调理剂处理。与对照相比,石灰、有机肥和调理剂处理酸杆菌门的相对丰度分别提高了64.77%、95.69%和67.52%,石灰处理变形菌门和硝化螺旋菌门的相对丰度分别提高了10.40%和11.99%,而有机肥处理降低了9.17%和43.0...

This study was conducted to investigate the response of soil bacterial community structure characteristics to different agronomic measures, as well as the relationship between community structure and soil environmental factors. Three treatments including lime, commercial organic fertilizer, and soil conditioner were set in purple mud paddy fields. The 16S rRNA gene of soil bacteria was sequenced, and the effects of different treatments on bacterial community composition and diversity were analyzed. The results showed that different agronomic me...
