(College of Horticulture,Northeast Ag/icultural University, Harbin 150030, China)Abstract: The configuration character, light and temperature capability in the 'Dongnong Three Chord Type' sunlight glasshouse was introduced. The 'Dongnong Three Chord Type' sunlight glasshouse (Sx) had better capability oflighting and heat preservation. Average percent of penetration light increased 3.0% and heat preservation increased 8℃ comparing to 'Dongnong 20-1' glasshouse (CK). With distance away front edge of glasshouse increase, ground temperature under the earth's surface lOcm increased in Sx and CK. Average ground temperature under the earth's surface 10cm increased 2.7℃ than CK.There was the highest value of ground temperature at 400cm apart from front edge of glasshouse, then ground temperature decreased.
