Welsh onion (Allium fistulosum L.) constitutes an important plant species cultivated in China due the benefits and applications in different areas. Moreover, nitrogen is an essential nutrient during the growth and development of plant. Here, we present the effects of nitrogen on soil microbiome in welsh onion plants. We used High-throughput sequencing analysis to determine the diversity and abundances of microbes associated to soil rhizosphere in welsh onion under the influence of nitrogen application. Nitrogen application significantly influenced in the diversity of fungal community. The relative abundance of Orbiliomycetes increased with the nitrogen concentration. Nitrogen application did not affect the diversity of bacterial community, whereas the relative abundance of Acidobacteria_Gp2, Verrucomicrobiae and Sphingobacteriia decreased with the nitrogen condition. In this work, we introduced evidences of the effect of nitrogen fertilization on microbial community in welsh onion rhizosphere, and the change of microbial community may interfere the growth and development of welsh onion.
葱（Allium fistulosum L.）是中国重要的栽培植物，具有多种益处和应用。氮是植物生长发育过程中的必需营养元素。本研究探讨了氮对葱根际土壤微生物组的影响。采用高通量测序分析，确定了不同氮处理下葱根际土壤微生物的多样性和丰度。氮处理显著影响了真菌群落的多样性。随着氮浓度的增加，Orbiliomycetes 的相对丰度增加。氮处理对细菌群落的多样性没有影响，但随着氮条件的变化，Acidobacteria_Gp2、Verrucomicrobiae 和 Sphingobacteriia 的相对丰度降低。本研究介绍了氮施肥对葱根际微生物群落的影响证据，微生物群落的变化可能会干扰葱的生长和发育。
