Effect Evaluation on Sediment Treatment of Drip Irrigation Project for the Yellow River Water

Sediment concentration of the Yellow River water is large.It is difficult to solve problem of drop head often blocked during popularization of drip irrigation technology.Through monitor of sediment composition and sediment concentration in each link in sediment treatment system for water source of typical drip irrigation project in Ningxia，sediment composition and treatment effect in different stages of sediment handling system were analyzed.And rationality of existing engineering design was evaluated.It provided reference for design of water saving irrigation project.
