摘要： A study was conducted during 2002-2018 to study the effects of conservation practice on soil biota properties in a sandy clay loam soil. Tillage treatments consisted of conventional tillage (CT), reduced tillage (RT) and no-tillage (NT). Residue treatments consisted of 0 residue input (NR), 50% residue input (HR), 100% residue input (TR). Microbial biomass C (MBC), urease (UA), and dehydrogenase (DHA) obtained a mean of 29.7-41.2% higher in RT and NT than in CT. In comparison with NR, HR and TR increased the numbers of mesofauna and macrofauna, but decreased the number of microfauna. The residue addition soils favored soil moisture, total organic C and available K. Soil fauna community analysis indicates that residue systems provide a more diverse residue resource entry into soil food webs, and that NT system is beneficial for soil ecosystem stability and sustainability.
