"十四五"我国温室能源与材料利用研究进展与展望OA

During'The 14th Five-year Plan'period,China's facility agriculture has advanced toward green,low-carbon,and high-efficiency development.The research and application of renewable energy utilization and novel greenhouse materials have become critical factors influencing facility production energy consumption and overall greenhouse performance enhancement.In terms of renewable energy utilization,a series of research achievements in clean energy sources,such as solar,biomass,geothermal,and wind energy,have been achieved and applied.Technical systems featuring multi-energy coupling,energy storage for peak shaving,and cascade utilization have gradually taken shape,improving the efficiency and stability of greenhouse energy supply.In terms of greenhouse material development,transparent covering materials are evolving toward spectral regulation,light energy conversion,and multifunctional integration.Phase-change materials(PCMs)for thermal storage have improved heat storage and thermal insulation performance through composite modification and encapsulation,while prefabricated,lightweight,and flexible composite walls achieve synergy between thermal insulation and heat storage,strengthening the capacity for greenhouse thermal environment regulation.Overall,China has preliminarily established an energy-saving technology framework integrating multi-energy synergy,composite functional materials,and intelligent control.However,challenges remain,including insufficient regional adaptability,limited system integration,inadequate validation of long-term material performance,and relatively high costs for industrial application.Future efforts should focus on strengthening the deep integration of energy,materials,intelligent energy control,and crop growth,promoting the upgrade of key technologies from individual breakthroughs to systematic integration and engineering applications,thereby providing support for the green,low-carbon,and high-quality development of facility agriculture.
