nitrogen runoff loss 氮素径流损失
By getting across of this inclined slope runoff experiment,we investigate in the control of soil nitrogen runoff effects on controlling nitrogen loss(urea). 本文通过斜面坡地径流实验,研究了控失氮肥(尿素)在控制土壤氮素径流损失上的作用效果。
The results showed that the soil and water conservation benefit of terracing was remarkbly lifted, the benefit of reducing runoff loss was 67.6%, and reducing soil loss was over 85.0%. 结果表明：坡耕地改梯田后蓄水保土效益显著提高，蓄水效益高达67.;6%25，保土效益达85
