Abstract: The physical characteristics of soil surface and their effects on soil moisture, heat, gas and fertility in the infiltration-ridged paddy field have been studied by comparision with the watcrlogging-leveling (conventional) paddy field. The results show that in the soil surface of infiltration-ridged paddy field, soilid, water and gas phases coexist and the rates of material cycle, energy transfomation, water, heat and gas exchanges and soil nutrients metabolism and availability of soil nutrients are higher than those in the watcrlogging-leveling paddy field. It is concluded that the infiltration-ridged paddy field is of high and effective material cycle and energy transformation.
