Design of decision support system for greenhouse environment control in cucumber cultivation

摘要

According to the data obtained from experiments and investigation, model-base, knowledge-base and database are established including the aspects of crop growth, environment control and economic analysis for cucumber grown in greenhouse. Based on these bases, a decision support system for environmental control and management in greenhouse is established under the software developing environment Delphi6.0. With consideration to both crop growth and economic profits, the system may give the optimized dynamic value of environment control parameters, such as temperature, light intensity, air humidity, carbon dioxide, according to different climate condition.
