| 中文摘要: |
| 通过不同施肥方式土壤间歇入渗试验，研究了施肥方式对土壤间歇入渗特性的影响。结果表明，不施肥与采用深施施肥方式对土壤间歇入渗能力影响不大，灌施间歇入渗量略大于深施，而表施间歇入渗量明显大于灌施与深施，不同施肥方式间歇入渗量的差异主要表现在第一周期。建立了不同施肥方式土壤间歇入渗模型，实例计算表明，该方法可简单而有效地确定土壤间歇入渗量。 |

| The influence of fertilizer application on intermittent infiltration characteristics of soil was studied based on indoor experimental data of intermittent infiltration under different modes of fertilizer application. The results indicated that no fertilizer or deep application had no obvious influence on intermittent infiltration capacity. The infiltration quantity under fertigation was a little more than that under deep application; while that under of surface application is significantly more than under deep application and fertigation. The difference of infiltration quantity under different modes of fertilizer application mainly presented in the first cycle period. The infiltration model under different modes of fertilizer application was proposed, and the example indicates that the method is simple and effective. |
