英文摘要: China solar greenhouse has made a great development since it has better properties on daylighting, insulation, and energy-saving. On the other hand, it also has some bottleneck problems to limit its sustainable development, such as continuous cropping obstacles, fertility degradation and pollution of soil, low water and nutrient management. Hence, it is very important to conduct the research on optimal strategy of environmental control and cultivating management to China solar greenhouse with closed soilless cropping system. In this project, tomato is selected as a research object and planted in the closed soilless solar greenhouse. The objectives of the research are the optimal control methods and strategies of environmental factors, the optimal control methods and strategies of nutrient solution and CO2 fertilizer supply, the deployment scenarios and the data fusion methods of sensor nodes. First, the dynamic model of environmental factors and the supply model of crop nutrients and CO2 fertilizer will be built taking into account all environmental factors and nutritional supplements. And then, the models will be optimized and simplified by the decoupled computing, data mining and data fusion, and linear/nonlinear dimensionality reduction operation. Finally, through the optimization of the sensor node deploymen
