【摘要】 针对目前农业科技园区的日光温室建造中存在投资过大和温室结构性能不甚理想两大问题,在冀中南地区气候型下对日光温室的结构性能进行整体改良。在保证温光性能的前提下,以高后墙、无后坡、超厚保温夹层、内吞式缓冲间为优化核心,形成经济型节能日光温室,并配以安全越冬设施保障系统。其冬季采光性能比冀优Ⅱ型日光温室提高了6 9%～18 4%,冬季采光时数增加了12 0%～43 9%;建造成本比冀优Ⅱ型日光温室降低了11 0%～20 3%。更多还原

【Abstract】 In allusion to two problems about bigger investment and lower performance of greenhouse in science and technology farm nowadays, the structure of greenhouse was improved on the climates in HEBEI province. There were tall back wall, non-roof, super thick sandwich for heat preservation and establishment-guarantee-system for live through the winter on the economy-type-sunlight-greenhouse (ETSG). Its light performance was increased by from 6.9% to 18.4% over JIYOU-Ⅱ-type sunlight-greenhouse in winter, its sunlight time was added by from 12.0% to 43.9%, and its investment was reduced by from 11.0% to 20.3%.更多还原
