摘　　要：为保证日光温室作物在寒冷季节正常生长,在日光温室中设置了燃池-地中热交换系统,该系统将燃池和地中热交换系统结合起来,以达到提高温室内土壤温度和气温的目的。初步研究表明,在地面以下0.35 m沿温室长度方向3个测点土壤平均温度分别为15.5℃、15.6℃、15.5℃,土壤温度分布均匀,较参考点平均温度分别提高1.9℃、2.0℃、1.9℃;沿温室跨度方向3个测点土壤平均温度分别为15.2℃、15.6℃、14.7℃,分别较对应参考点平均温度提高2.7℃、2.0℃、3.7℃;温室内平均气温为21.4℃,较参考点平均气温提高2.6℃,室内外温差达到34.0℃。使用燃池-地中热交换加热系统,对提高温室内土壤温度、气温均具有较好的效果。In order to raise soil temperature and air temperature in solar greenhouse ,fire-pit and underground heating exchange system which connected the fire-pit with underground heating exchange system were designed. The average temperatures of three different test points of soil（350 mm below the earth surface） in length of solar greenhouse are basically uniform, which are 15.5℃, 15.6℃ and 15.5℃, increasing by 1.9℃, 2.0℃ and 1.9℃, respectively, in width of solar greenhouse, which are 15.2℃, 15.6℃ and 14.7℃, increasing by 2.7℃, 2.0℃ and 3.7℃. The average temperature in the solar greenhouse reaches 21.4℃ with the increase of 2.6℃ the temperature difference between inside and outside reaches 34.0℃. The results show that, during the winter seasons, using the fire-pit and underground heating exchange system has better efficiency to raise the soil temperature and the air temperature.
