Effects of intercropping on fungi and nutrients in rhizosphere soil of Paeonia rockii
摘要
Abstract
This study aims to explore the effects of different intercropping patterns on the chemical properties and fungal community structure in the rhizosphere soil of Paeonia rockii.The chemical properties,enzyme activities,and fungal community characteristics in rhizosphere soil and their correlations under different intercropping patterns including Paeonia rockii monoculture(CK),Paeonia rockii with broad bean(CD),and Paeonia rockii with flax(HM)were analyzed.The results indicated that under HM and CD patterns,the hydrolyzable nitrogen(HN)content in the rhizosphere soil of Paeonia rockii showed significant differences compared to CK(P<0.05).The available phosphorus(AP)content under the HM pattern,as well as the soil organic matter(SOM)content and cellulase(CL)activity under the CD pattern,were the highest.The fungal diversity(ACE index)in the rhizosphere soil of CD and HM patterns was higher than that of CK(P<0.05).At the phylum level,Basidiomycota and Ascomycota were dominant across all patterns.At the genus level,Calyptella had higher relative abundance under the CD pattern,while Hebeloma had higher relative abundance under the HM pattern.Functional classification of soil fungi showed that saprophytes had the highest relative abundance.Spearman correlation analysis revealed that SOM content and CL and catalase(CAT)activities had the highest correlations with rhizosphere soil fungal communities under different intercropping patterns.In conclusion,intercropping with flax and faba beans can both improve the fungal community structure in the rhizosphere soil of Paeonia rockii,increase fungal diversity,and enhance soil nutrient fertility,with the CD pattern demonstrating better performance.关键词
