摘 要：
The major soil animal groups, enchytraeid worms and oribatidmites, were compared in the abundance and diversity betweenconventional fields (CT)and organic farming fields with tillage (CT)or no-tillage (ON) practices. The values of abundance, speciesrichness, diversity and evenness were significantly larger in OT andON than in CT, indicating that the abundance and diversity in organicfarming fields were greater than those in conventional farming. Thecommunity structure of enchytraeid genera was different between OTand ON. Enchytraeus was the most abundant in OT, while fridericia inON. The abundance of oribatids in OT was similar to that in ON, whilethe species richness and diversity in the former were smaller. Theseresults suggested that on-tillage practice under organic managementmight contribute to the improvement in Quality of soil mesofauna.
