- Abstract:
- The mathematics simulation models of point source infiltration interrelated with drip irrigation water dynamic are summarized,and the structure,characteristic and problem of analytical model,numerical model and empirical model are discussed.The drip infiltration water move model considered crop root’s water absorption was presented,which indicated the precision treatment of root water absorption was a key issue in the future research.
