Abstract:
A long-term experiment showed that under ridge-no-tillage, the amount of soil animal in 0 - 20 cm layer was 14700 ind. x m(-2), while under no-tillage and fallow in winter, paddy-upland rotation, and conventional tillage, it was 10450, 7950 and 6275 ind. x m(-2), respectively. Soil microbial biomass and microbial biomass N were more in spring and autumn, and less in summer. Soil enzyme activity was higher in surface soil layer and lower in bottom soil layer. The amount of soil animal, microbial biomass and microbial biomass N and soil enzyme activity was in order of ridge-no-tillage > paddy-upland rotation > no-tillage and fallow in winter > conventional tillage. The results also indicated that ridge-no-tillage was advantageous to improve soil ecological environment and soil fertility in paddy field.
