摘要
讨论了温室热能损失的主要方面 ,并在试验的基础上介绍了温室在夏季与冬季热能经地层土壤散失的情况 ,指出在寒冷地区的温室中 ,经地层土壤传导的热流密度是可观的。建议应该在温室的地层中增设保温层 ,并指出采用栽培床以减少灌溉水引起的热能损失的必要性。
Heat loss in agricultural greenhouses in cold region is discussed and a experiment of heat loss through underground soil layer of greenhouse is presented.The experimental results show that the under ground heat loss is considerable in cold climate and it is necessary to build a underground heat conservation for greenhouses.
