From the view of practice and application, the situation of research and development for environmental control and simulation models of greenhouse were described. The multiple processor distributed control systems are widely used for greenhouse environment, and the single chip processors with the universal structure and low price are mainly used as the controller of the systems. The IPC (industrial personal computer) can also be used as the controller but its price is relatively expensive. The intellectualization of the control systems and the signal wireless transmission are significant trend for the environmental control of the greenhouse, and the wireless transmission is more suitable for greenhouse characteristics. It should be considered to integrate environmental control with crop growth models and greenhouse production economy (benefits), but it’s difficult to do at present. The simulation models can help to know better about the effect factors on greenhouse environment. It’s not necessary to over emphasize the precision of rare level control system.
