Technology of Greenhouse Environment Control Based on Economical Optical

Method of environment control of greenhouse based on model was put forward.The suitable temperature,nighttime mean temperature and 24h mean temperature in greenhouse environment control were given.Greenhouse environment control sys-tem based on the models was founded.The system could give the project of greenhouse environment control based on the cur-rent environment parameter in greenhouse,and control the greenhouse environment connecting with the greenhouse environment controller.The result showed it was a good method for greenhouse environment control.
