Abstract：According to micro-irrigation hydraulics characteristic,combining the search principle of bisection algorithms and back step method,the lateral hydraulic analysis and design method of micro-irrigation were put forward.Using the computer program to calculate from the end to inlet of lateral,the pressure and discharge of each emitter on the lateral could be derived.The lateral running hydraulic parameter could be designed.The average discharge,discharge variation,and design control index could be checked very fast and conveniently.This method is intuitive,simple,efficient and easy for non-professionals to understand and use.Test results show that the method has a higher efficiency and the solution accuracy.laterals;micro-irrigation;bisection algorithms;reverse recursion;discharge variation
