- 摘要:
- 以宁夏回族自治区平罗县3种不同盐渍化程度（低盐（<1%）、中盐（1%~3%）和高盐（>3%））土层土壤为研究对象，采用方差分析和冗余分析等统计方法，研究了不同盐渍化程度土壤对土壤理化性质和真菌群落组成结构的变化及其相互作用关系的影响，以期为宁夏河套灌区盐碱地改良提供参考依据。结果表明：低盐土壤有机碳、全氮、有效磷和速效钾含量显著高于中盐和高盐土壤（P<0.05）；3种不同盐渍化程度土壤真菌多样性指数无显著差异（P>0.05）；低盐和中盐土壤真菌多样性均高于高盐土壤。土壤真菌多样性与土壤有机碳、总氮、有效磷、pH呈正相关关系，与土壤全盐含量呈负相关关系。3种不同盐渍化程度土壤真菌中子囊菌门、毛霉菌门和担子菌门均为优势门，被孢霉属和毛壳菌属均为优势属。真菌群落主要由腐生营养型、病理营养型和共生营养型等3类功能群构成，其中腐生营养型具有显著优势。相关性热图和RDA分析表明，土壤有机碳、全氮、有效磷与土壤真菌群落结构呈显著相关关系。土壤有机碳、全氮和有效磷是影响不同盐渍化程度土壤真菌群落组成、结构变化的主要因素。
- Abstract:
- Taking the soil layers with three different degrees of salinization (low salt (<1%)，medium salt (1%-3%)，and high salt (>3%)) in Pingluo county，Ningxia Hui Autonomous Region as the test materias，statistical methods such as analysis of variance and redundancy analysis were adopted to study the effects of soils with different degrees of salinization on the changes of soil physical and chemical properties and the composition structure of fungal communities，as well as their interaction relationships，in order to provide references for the improvement of saline-alkali land in the Hetao Irrigation district of Ningxia.The results showed that the contents of organic carbon，total nitrogen，available phosphorus，and available potassium in low-salinity soil were significantly higher than those in medium-and high-salinity soils (P<0.05).There was no significant difference in fungal diversity indices among the three salinization levels (P>0.05)；however，fungal diversity in low-and medium-salinity soils was higher than that in high-salinity soil.Fungal diversity was positively correlated with soil organic carbon，total nitrogen，available phosphorus，and pH，but negatively correlated with total salt content.In soils of all three salinization levels，Ascomycota，Mucoromycota，and Basidiomycota were the dominant phyla，while Mortierella and Chaetomium were the dominant genera.The fungal community was primarily composed of three functional groups,saprotrophic，pathotrophic，and symbiotic，with saprotrophic fungi being significantly dominant.Correlation heatmap and RDA analysis indicated that soil organic carbon，total nitrogen，and available phosphorus were significantly correlated with soil fungal community structure.In conclusion，soil organic carbon，total nitrogen，and available phosphorus were the main factors influencing the composition and structural variation of fungal communities in soils with different salinization levels.
