摘　　要：介绍了"东农三弦式"日光温室(Sx)的结构特点和光温性能。研究表明,"东农三弦式"日光温室(Sx)具有良好的采光性和保温性,与东农20-1温室(CK)相比,平均透光率提高3.0%,保温效果提高8.4℃,试验的两温室地表下10cm的地温均随着距前沿距离的增加而增加,在距前沿400cm处达到最高值,而后地温下降,地表下10cm平均地温Sx比CK提高了2.7℃。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 of lighting 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 10cm 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.
