Abstract:
Aiming at the problems of poor reliability of environmental parameter acquisition and control and extensive regulation of water and fertilizer in the process of facility strawberry production, a facility strawberry intelligent production management and control system is designed and developed. The system includes two parts: information of environment growth perception system and implementation of environment control system. The multi-sensor data fusion algorithm and expert decision control system model improved the accuracy and authenticity of environmental parameter acquisition. It ensured the accurate control of environment growth and water and fertilizer demand at each growth stage of strawberry. At present, the system runs well in the strawberry glass greenhouse in the demonstration park. The utilization rate of water and fertilizer and the ability of environmental regulation have increased by 76.5% and 35.5%, respectively, and the yield and quality of strawberries have also greatly improved.
