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 structural characteristics and light and temperature properties of “Dongnong Sanxian” solar greenhouse (Sx) were introduced. The results showed that the light-harvesting and heat-preserving properties of Sangong Sanshen Solar Greenhouse (Sx) were better than those of Dongnong 20-1 Greenhouse (CK), the average light transmittance increased by 3.0% and the heat preservation effect increased by 8.4% ℃. The ground temperature of 10 cm above ground surface in two greenhouses increased with the increase of the distance from the front and reached the maximum value at 400 cm from the front, and then the ground temperature decreased. The average ground temperature Sx of 10 cm above subsurface increased by 2.7 ℃ than CK.
