中文摘要：

大跨度非对称水控酿热保温日光温室（简称大跨度日光温室）的特点是在温室的北部建造了水控酿热发酵池,提高了温室的保温蓄热能力。该试验以大跨度日光温室为研究对象,在冬季典型晴天（2016-01-28）,阴天（2016-01-13）和雪天（2016-02-12）的条件下,将大跨度日光温室与苯板砖墙温室进行对比,分析了其光照强度、温度日变化、土壤温度日变化等性能。结果表明：晴天条件下,大跨度日光温室夜间的平均温度为11.7℃,阴天为10.8℃,雪天为9.9℃;晴天条件下,大跨度日光温室夜间的平均土壤温度为10.8℃,阴天为13.9℃,雪天为11.4℃。大跨度日光温室的夜间平均温度能满足冬季作物的要求,且该温室比苯板砖墙温室建造成本降低了39.6%,土地利用率提高了30%以上,适合在西北地区进一步推广和应用。

英文摘要：

A kind of large-scale and water-control energy storage asymmetric solar greenhouse was for short large- scale solar greenhouse,which in the north of the solar greenhouse was built a water-control energy storage septic tank which can improve the heat storage capacity of the solar greenhouse. The performance of the large-scale solar greenhouse was tested in a sunny day（2016-01-28）,cloudy day（2016-01-13） and snowy day（2016-02-12） by comparing with the local solar greenhouse whose north wall was made by porous brick and EPS in last winter. The results showed that in a sunny day,the average air temperature of night in the large-scale solar greenhouse was ll. 7 ℃ ,which was 10. 8 ℃ in a cloudy day and 9. 9℃ in a snowy day. At the same time,the average soil temperature of night in the large-scale solar greenhouse was 10. 8 ℃ in the sunny day,which was 13.9 ℃ in the cloudy day and 11.4℃ in the snowy day. This eyperiment proved that the environment of the large-scale solar greenhouse was available for the crops in winter season. For the large-scale solar greenhouse,could save 39.6% in cost and the land utilization could be improved by more than 30%. The results suggested that the new solar greenhouse was available in Northwest China.
