| Abstract: |
| Since the single regulating measure is not good enough in water and soil conservation,this study analyzed the effects of corn yield,regulating rates of runoff and silt caused by different compound regulating measures at the natural raining.The results showed that: the regulating measures could effectively control the runoff and silt on sloping fields.They could decrease the runoff and silt from sloping fields obviously,and increase the crop yield at the same time.We found that corn + PAM was a good compound regulating measure for the control of the sloping runoff and silt because it was cheap in cost,easy to carry out and could control the runoff and silt from sloping fields and increase yield effectively at the same time. |
