Abstract: In order to evaluate the effects of no-tillage and stubble mulch on the soil meso-microfauna assemblages, the abundance, community composition and seasonal variation of soil meso-microfauna were investigated in the Conservation Tillage Research and Development Station of Chinese Academy of Sciences in Lishu County, Jilin Province in April, July and October, 2015. A total of 18 309 soil meso-microfauna were obtained, which belonged to 2 phyla, 6 classes, 16 orders. Among them, the dominant group is Oribatida, Mesostigmata, Hypogastruridae and Isotomidae. The individual density of soil meso-microfauna in no-tillage plots was higher than that in other treatments, while the highest taxon richness and diversity index was appeared in the stubble mulch plot. The highest individual density was recorded in October for all treatment plots. Major soil animal groups differed in response to tillage methods and seasonal variations. Compared with conventional tillage, no-tillage and stubble mulch could increase the individual density of major soil animal groups.
