Abstract:This experiment used 4 common types of solar greenhouse as targets.Their back wall materials from the inside to outside are 37 cm brick+10 cm polyphony board+24 cm brick,20 cm ceramic brick+10 cm perlite+20 cm ceramic brick,Shouguang type loam wall,37 cm brick+12 cm polyphony board,respectively.According to the structure parameters and building materials of these 4 types solar greenhouses,we analyzed their lighting angle and heat preservation functions,and measured the indoor and outdoor temperatures of the solar greenhouses in winter of 2010-2011.The results showed that the temperature of Beijing in winter of 2010-2011 is normal but leaning to cold.Thermal resistance of the greenhouse with 37 cm brick+10 cm polyphony board+24 cm brick back wall is 3.41 m2 K W-1.The average indoor temperature is 14.4 ℃.The average night temperature is above 10 ℃.The lowest temperature is above 6 ℃.The average temperature inside of Shouguang type greenhouse is 12.4 ℃.The average temperature at night is above 8.4 ℃.The lowest temperature is above 4.6 ℃.These 2 types of solar greenhouses can ensure the fruit vegetables production in winter.Greenhouses with 20 cm ceramic brick+10 cm perlite+20 cm ceramic brick and 37 cm brick+12 cm polyphony have lower indoor temperatures.The lowest temperature is around 0 ℃.The average temperature at night is between 5-7 ℃.They are only good for cultivating cold-tolerant leaf vegetables in winter.
