Abstract:Rational design of lateral discharge regulator in micro-irrigation project will effectively improve irrigation quality,reduce project cost,but at the same time increase energy consumption.By considering the case design for 4 drip irrigation systems with and without lateral discharge regulator,the project cost and energy consumption were analyzed,the economic feasibility of the discharge regulator application was discussed,and the methods were presented to evaluate the economic feasibility.The results showed that the discharge regulator cost was not obvious to the micro-irrigation project cost;the allowable pressure head lower limit value was remarkable to the project energy consumption influence.If the allowable pressure head lower limit value is bigger than its economic threshold value,using the discharge regulator will be uneconomical.The selection and use of discharge regulator′s type,specs and running parameter for technical and economic analysis are discussed.
