- 摘要:
- 以黄河三角洲盐碱地（光板地、獐茅地、翅碱蓬地、柽柳地）土壤为研究对象，采用454高通量测序技术，对土壤中真菌群落和多样性进行了研究。结果表明：检测出的土壤真菌类群达5门22纲59目87科157属，其中，子囊菌门在所有样地中相对丰度最高，担子菌门次之。不同采样环境土壤中真菌多样性存在一定差异，光板地中多样性指数最高（2 070），獐茅地中最低（1 490）。子囊菌门和球囊菌门与土壤碱解氮相关性最大，担子菌门和壶菌门与土壤碱解氮和电导率相关性较大，毛霉亚门受速效磷影响最大。土壤速效磷对真菌属的作用最大。
- Abstract:
- Saline alkali land soils，including Bare land，Aeluropus littoralis var.sinensis，Suaeda glauca，Tamarix chinensis，were researched by 454 high-throughput sequencing technologies to study soil fungal community and diversity.The results showed that,5 phyla，22 classes，59 orders，87 families，and 157 genus were obtained.Ascomycota was the most predominant phylum in all plots，Basidiomycetes was the second predominant phylum.Soil fungal diversity existed certain difference in different samples，and the diversity index in bare land was the highest (2 070) and in Aeluropus littoralis var.sinensis was the lowest (1 490).The relevance between Ascomycota with soil available nitrogen and Glomeromycota with soil available nitrogen were maximum.The relevance between Basidiomycota with soil available nitrogen，with conductivity，and Chytridiomycota with soil available nitrogen，with conductivity were more higher.Available phosphorus was the maximum factor to Mucoromycotina.The effect of soil available phosphorus on the fungi was the largest in the five environmental variables.
