| Abstract: |
| In this article, on the basis of the comprehension on domestic and foreign literatures relevant to this research, progress of muddy water infiltration mechanism and muddy water infiltration model were analyzed. It could be concluded that a big portion of the experiments were accomplished using static water for muddy water irrigation infiltration test, and a relative small portion was done using dynamic water to do so. More achievements were obtained by studying the influence of different sand content on soil infiltration than by investigating the influence of different sediment grain size on soil infiltration. More studies on muddy water irrigation soil infiltration than on a second irrigation over soil infiltration after a dense layer was formed. Indoors utilization of equipment such as infiltration ring on soil infiltration was more than field test. Infiltration experiments in bare land were more than those in field soil with growing crops. To gain insightful understanding on soil infiltration mechanism of muddy water irrigation, it is advised that dynamic water may be involved in muddy water irrigation infiltration test. The influences of different sediment grain size composition, field crops, many muddy water irrigations, and water/fertilizer coupling under muddy water irrigation may need to take into experimental consideration. Muddy water in film hole irrigation experimental study should become the focus, gradually allowing in-depth research on characteristics of muddy irrigation water infiltration, and providing a theoretical basis for practical application. |
