The whole crop cultivation season was divided into two periods, namely vegetative stage to reproductive stage. In vegetative stage, the temperature was taken as a principal parameter, prior to other parameters in greenhouse. According to the corresponding magnitude rank of temperature rising or cooling, actuating mechanisms were carried out to meet control requirements. In reproductive stage, the control strategies were acted as economic optimized methods. Putting control cost models, predicted environmental parameters control model and the crop growth models in unite system to maximize the greenhouse input/output as control objective. So it could create favorable microclimate parameters and conditions to fit crop growth and development. And the system to cucumber round production was carried out. Practices showed that with the control system based on economic optimization strategies to manage crop growth and development, favorable control effects and lower cost were gained.
