Abstract:: The structure of Liaoyang type solar greenhouse is special,which is assembled by a wall made of galvanized steel and grass,instead of the traditional thick walls,improve land utilization,without destroying the plow layer,conducive to crop growth.The temperature,soil temperature and humidity of Liaoyang and Baiyin solar greenhouse for two years in December and January were compared,the characteristics of Liaoyang type greenhouse temperature and humidity were analyzed,in order to provide a theoretical basis for the promotion of the use of such greenhouse.The results showed that Liaoyang type greenhouse average minimum temperature was lower than the Baiyin type temperature 1.2℃ and 0.8℃ in 2012 and 2013；Endothermic phase,Liaoyang type average hourly elevated temperature 4.8~5.3℃,but the Baiyin type greenhouse elevated temperature .8~4.7℃;Liaoyang type greenhouse humidity was higher than Baiyin type greenhouse 3.9%~8.6%,the soil temperature difference between the two greenhouse was unlikely.
