Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation analysis subsystem, control methods, can instruct users to irrigation greenhouse through quantitative calculating greenhouse crop water requirement. The system has been examined in greenhouses of ShengFangYuan Test Station in Beijing, China; the result shows that the system can instruct greenhouse irrigation efficiently, increase yield 18%, and save water 28%.
