| Abstract: | The preferential flow is the universal phenomenon of water flow in soil.In this paper,the basic property of preferential flow,the impact of preferential flow on environment,especially on water and agri-chemicals,in soil were reviewed.The impact of root on preferential flow was described,furthermore the dynamic change of root affecting soil preferential flow was thought.The general research method were reviewed.Some problems in research on the root system and preferential flow were presented. |
