| 摘 要： | 为明确高温覆膜对韭菜根际土壤微生物群落多样性和组成的影响。本研究在覆膜前后对韭菜根际土壤中总DNA进行提取，采用Illumina Hiseq 2500高通量测序技术对土壤中细菌的16S rDNA和真菌的ITS基因进行了序列测定，分析了高温覆膜前后韭菜根际土壤中微生物群落结构特征。结果表明，高温覆膜前后分别获得细菌OTUs 1849个和1819个，真菌OTUs 148个和151个，无显著差异。覆膜前后物种分类显示，细菌种类均隶属于24门53纲112目218科322属，其中优势类群为蛋白菌门、厚壁菌门和放线菌门，覆膜前后的相对丰度分别为43.79%、21.70%、21.03%和42.36%、17.55%、23.92%。真菌种类均隶属于4门10纲21目27科34属，优势类群为子囊菌门和担子菌门，覆膜前后的相对丰度分别为62.48%、15.28%和51.13%、40.95%。可见，土壤中细菌群落的多样性和丰富度均高于真菌，覆膜前后微生物总量无显著变化，细菌、真菌在多样性指数上无显著差异，而在结构组成上差异显著。

| Abstract: | The aim of this study was to clear the effect of high temperature film mulching technology on soil microbial community in the rhizosphere of Chinese chive. The total DNA of Chinese chive rhizosphere soil before and after the high temperature film mulching were extracted, the 16Sr DNA of bacteria and ITS genes of fungal in the soil were sequenced by Illumina Hiseq 2500 high throughput sequencing, and the microbial community structure characteristics of the rhizosphere soil were analyzed. The results showed that the bacteria OTUs and the fungi OTUs before and after the high temperature film mulching were 1849 and 1819, 148 and 151, respectively, and, and there was no significant difference. According to the classification of species before and after the high temperature film mulching, the species of bacteria belonged to 24 phyla, 53 classes, 112 orders, 218 families and 322 genera. The dominant groups were Proteobacteria, Firmicutes and Actinobacteria, and their relative abundances were 43.79%, 21.03%, 21.70% and 42.36%, 23.92%, 17.55%, respectively. Fungal species belonged to 4 phyla, 10 classes, 21 orders, 27 families and 34 genera. The dominant species were Ascomycota and Basidiomycota, and their relative abundances were 62.48%, 15.28% and 51.13%, 40.95%, respectively. The results indicated that the diversity and richness of bacterial community in soil were higher than those of fungi. There was no significant change in total microbial biomass before and after mulching. There was no significant difference in diversity index between bacteria and fungi, but significant difference in structure composition. |
