Abstract：In order to improve the thermal insulation and heat storage performance of solar greenhouses in winter，this study designed a new type solar greenhouse with assembly structure for active heat storage and release，and actually tested the environmental performance of this greenhouses in the cold period of winter in Hebei，Inner Mongolia，and Ningxia regions．The results showed that the average daily temperature and mean value of daily minimum temperature in greenhouse at tested regions were 15-21 ℃ and 9.0-17.7 ℃，respectively．The average duration of daytime when indoor temperature greater than 15 ℃ all exceeded 7 h．And the daily average temperature at night and average value of indoor and outdoor temperature differences were 12.1-18.4 ℃ and 18.7-33.8 ℃，respectively．In absence of the other auxiliary heating conditions，the new type solar greenhouse with assembly structure for active heat storage and release has good thermal insulation and heat storage performance，strong applicability，and can meet the winter production needs of prefer warmth crops．
