Ramie ( Boehmeria nivea  L. Gaud) fiber, one of the most important natural fibers, is extracted from stem bark. Continuous cropping is the main obstacle to ramie stem growth and a major cause of reduced yields. Root-associated microbes play crucial roles in plant growth and health. In this study, we investigated differences between microbial communities in the soil of healthy and continuously cropped ramie plants, and sought to identify potential mechanisms whereby these communities could counteract the problems posed by continuous cropping. Paired-end Illumina MiSeq analysis of 16S rRNA and ITS gene amplicons was employed to study bacterial and fungal communities. Long-term monoculture of ramie significantly decreased fiber yields and altered soil microbial communities. Our findings revealed how microbial communities and functional diversity varied according to the planting year and plant health status. Soil bacterial diversity increased with the period of ramie monoculture, whereas no significant differences were observed for fungi. Sequence analyses revealed that  Firmicutes ,  Proteobacteria , and  Acidobacteria  were the most abundant bacterial phyla.  Firmicutes  abundance decreased with the period of ramie monoculture and correlated positively with the stem length, stem diameter, and fiber yield. The  Actinobacteria ,  Chloroflexi , and  Zygomycota  phyla exhibited a significant (P < 0.05) negative correlation with yields during continuous cultivation. Some  Actinobacteria  members showed reduced microbial diversity, which prevented continuous ramie cropping.  Ascomycota ,  Zygomycota , and  Basidiomycota  were the main fungal phyla. The relatively high abundance of  Bacillus  observed in healthy ramie may contribute to disease suppression, thereby promoting ramie growth. In summary, soil weakness and increased disease in ramie plants after long-term continuous cropping can be attributed to changes in soil microbes, a reduction in beneficial microbes, and an accumulation of harmful microbes.
