Abstract:: 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 11.7 ℃，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.
