地下热交换日光温室在地面下５０ｃｍ处埋设管道，可利用集蓄太阳能的办法，提高早春和晚秋塑料日光温室的气温与地温，促进蔬菜的早熟与延后生产．１９８７～１９８８年我们在地下热交换日光温室进行了番茄与辣椒等蔬菜的栽培试验，早春收获时期比对照温室提早７ｄ左右，前期产量提高１．３倍左右，总产量提高４０％以上，具有良好的经济效益与社会效益．
Underground heat exchange solar greenhouse buried in the ground 50cm below the pipeline, solar energy can be used to save the way to improve early spring and late autumn plastic greenhouse temperature and ground temperature, and promote premature and delayed production of vegetables. From 1987 to 1988, we carried out the cultivation of vegetables such as tomato and peppers in underground heat exchange solar greenhouse. The early spring harvest period was about 7 days earlier than the control greenhouse, the early yield increased about 1.3 times and the total output increased by 40% or more, with good The economic and social benefits.
