日本静冈柑桔试验场1979年试造了新的地下蓄热式太阳能塑料温室,他们在温室里试种了11种中晚熟柑桔品种,对这栋新温室进行了实用性试验。该温室是一座门面宽4.5米、高3米、长35米的单栋管道温室。在室内地下80—40厘米处2层共埋设了3排盐被管。用鼓风机把中午室内的高温空气送入管内,使其作为地温蓄热,到夜间再放出来增加室内温度,这样可望使夜间室温提高10—13℃。
In 1979, Shizuoka Citrus Experimental Station in Japan experimented with a new underground regenerative solar greenhouse, in which 11 middle-late-maturing citrus cultivars were planted in the greenhouse and practical tests were conducted on the new greenhouse. The greenhouse is a 4.5-meter wide, 3-meter-high and 35-meter long single-walled greenhouse. In the indoor underground 80-40 cm 2 layers were buried a total of 3 rows of salt pipe. Use the blower to send the hot air in the noon room into the tube to make it as the ground temperature heat storage, and then release it at night to increase the indoor temperature, so that it is expected to raise the room temperature by 10-13 ℃ at night.
