以锰矿渣为基质开展了植物修复中试试验,测定对比了有机菌肥处理下不同植物群落模式配置中基质重金属浓度和其他理化性质的差异,同时利用Illumina Miseq平台对各处理基质样本中菌群的16S rRNA基因V4区域进行测序,分析了细菌群落结构及多样性的变化。试验结果表明施用有机菌肥能显著降低了土壤重金属活度,改善了根际微生态环境。基因测序分析中共检测到了150 703个有效序列,基质样本中的微生物隶属34个门类和81个纲类,变形菌为优势菌群。有机菌肥的应用显著改变了基质中微生物的组成、结构与相对丰度,丰富了菌群多样性。总体上,有机菌肥对细菌群落结构的影响要大于植物群落模式的影响。RDA分析显...

Pilot scale phytoremediation tests using Mn mining wastes as substrate were carried out to compare the effects of bacteria containing-organic manure application and plant community model on soil heavy metal concentration and other related properties. Illumina sequencing technique was applied to analyze the characteristics of rhizobacteria and related changes in bacterial community structure and diversity. The result showed that the application of organic manure significantly reduced soil heavy metal activity and thus improved the rhizosphere’s...
