This paper discusses the effects of subsoil breaking on the change of pressure head, soil temperature and runoff discharge in space and time in a sloping field. A controlled comparison experiment was conducted in a subsoil breaking field and a no-subsoil breaking field. The results showed that the runoff ratio of the subsoil-breaking field was about 1/10 of that in the no-subsoil breaking field. This indicates that subsoil breaking promotes the infiltration of rainfall into the soil and can reduce the surface runoff discharge. The spatial distribution of the equi-pressure heads during rainfall was complicated, and the coefficients of variation were large. However, that of the equi-pressure heads before and after rainfall showed the similar patterns of variation in both fields. As for soil temperatures, we didn’t observe a large difference between the subsoil breaking field and the no-subsoil breaking field, and the spatial variation was smaller than that of the pressure head.
