Response of Soil Fauna Community to Different Planting Years of Paeonia suffruticosa in Spring
[Objective]The aim of this study was to investigate the impact of different consecutive years of Paeonia suffruticosa cultivation on the community structure of spring soil fauna.[Method]Macro-fauna were collected by manual picking,and meso and micro-fauna were separated using the dry-wet funnel method.The adjacent wasteland was selected as the control(CK),the characteristics of the soil fauna communities were studied after 1 year(F1),2 years(F2),3 years(F3),and 4 years(F4)of con-secutive P.suffruticosa cultivation.[Result]A total of 190 soil animals were captured,representing 2 phyla,7 classes,15 orders,and 31 families.The dominant groups were Isopoda and Chilopoda.Over-all,compared to the CK,P.suffruticosa cultivation increased the number of soil fauna groups,showing a parabolic trend with consecutive years of cultivation.The peak number and average density of soil fauna groups occurred after 3 years(F3)of P.suffruticosa cultivation.Additionally,except for F3,the soil fauna density decreased in the other years of P.suffruticosa cultivation.The richness index of soil fauna showed an increasing trend with consecutive cultivation years,while the diversity index exhibited a para-bolic trend,dominance index decreased gradually,and the evenness index fluctuated slightly.The densi-ties of predatory and omnivorous soil fauna initially increased and then decreased with consecutive culti-vation years.[Conclusion]Overall,short-term P.suffruticosa cultivation benefits the development of soil faun communities,but extended cultivation years eventually restrains the soil fauna communities.
