| Abstract: |
| In the experiments of fertile solution infiltration, the main effects of cycle rate on the infiltrated water and NO-3-N transfer and distribution with a 70 cm groundwater table are shown as follows：（1）To some extent，infiltration rate decrease with a decreased cycle rate；In this experiment，the optimal cycle rate is 1/4，which leads to a shallower distribution of the moisture and NO-3-N in soil and weakens the trend of NO-3-N leaching；（2）The concentration of NO-3-N in the groundwater is least when the cycle rate is 1/3. |
