The optimal control methods and techniques of greenhouse environment can effectively improve the production conditions of greenhouse crops and utilization efficiency of light energy resources, so as to realize the production of high yield, high efficiency and high quality. In order to make full use of domestic and international research results in greenhouse environmental control, and promote Chinese development in greenhouse area, the recent research progress of greenhouse environment control methods was summarized from five aspects based on set point, intelligent algorithms, multi-objective optimization, multi-factors coupling and crop growth information. It was considered that the major scientific problems should be solved in the future, which involved efficient control mechanism of light/temperature/nutrition coupling, high-throughput detecting method of plant phenotype. In this way, the key technologies in greenhouse can be broken through, such as information perception, internet of things, wisdom management and control, etc. A technology system of intelligent measurement and control with Chinese characteristics in greenhouse would be formed.
