Abstract:

In order to clarify the effect of no tillage with high stubble on soil macrofauna community, soil macrofauna community under the treatments of conventional tillage (CT), no tillage (NT) and no tillage with high stubble (SS) was investigated in the research and development base of conservation tillage in Lishu County, Jilin Province, in spring, summer and autumn. Soil macrofauna were obtained belonging to 2 phyla 4 classes 14 orders. In each treatment, Enchytraeidae was the dominant group, while Coleoptera, Geophilomorpha, Diptera larvae and Formicidae were common. In spring, the density of soil macrofauna under NT treatment was significantly (P<0.05) higher than that under CT by 2.8-fold. In summer, the density of soil macrofauna under SS treatment was significantly higher than that under CT by 1.8-fold. In antumn, the density of soil macrofauna under NT and SS was significantly higher than that under CT by 1.1-fold and 1.3-fold, respectively. The density of soil macrofauna was low in spring and high in autumn. The community composition of soil macrofauna under SS treatment varied from that under CT treatment, especially in summer and autumn, but the difference between SS and NT was not significant. The density of Enchytraeidae was significantly increased under SS treatment in summer and autumn compared with that under CT. In general, no tillage with high stubble was beneficial to increase the density of soil macrofauna.

Key words: soil macrofauna, no tillage with high stubble, community structure, black soil
