摘　　要：长期以来,夏季生产能耗大、产量低一直是制约设施蔬菜发展的瓶颈问题,在确保高质高产的前提下寻求低能耗的温室生产方式是当前设施农业的基本要求之一。针对夏热冬冷地区连栋温室夏季遮阳问题,以南京市某连栋温室为例,采用Ecotect Analysis模拟分析温室内部光热环境,结合作物生长的适宜条件,确定夏季外遮阳网的改进方案及揭盖网时间,并通过生命周期评价法得出优化后的遮阳方案能在一定程度上降低能耗,这可为外遮阳网的设计及揭盖网时间的确定提供参考。For a long time, high energy consumption and low yield in summer production have been the bottleneck problem restricting the development of facility vegetables. It is one of the basic requirements of facility agriculture to seek a low energy consumption greenhouse production mode on the premise of ensuring high quality and high yield. Aiming at the problem of sunshade net in summer for multi-span greenhouses in hot summer and cold winter areas, took a multi-span greenhouses in Nanjing as an example and adopted Ecotect Analysis to simulate and analyze the internal light and heat environment of the greenhouses. Combined with suitable conditions for crop growth, it determined the improvement scheme of summer external sunshade net and the time of covering and uncovering the net. Through the Life Cycle Assessment, it is concluded that the optimized sunshade scheme can reduce energy consumption to a certain extent, which can provide a reference for the design of the outer sunshade net and the determination of the time of covering and uncovering the net.
