开发利用地热资源,修建地热温室,既能为市场提供大量优质淡季鲜菜,保证市场供应,又能节省能源,降低蔬菜生产成本,提高经济效益和社会效益。我们于1986～1988年对东汤地热温室的性能进行了测试。结果表明: 1.铺设地温管效果 提高了地温。地温管上部,距地温管越近,增温效果越显蓍。铺设6道地温管比 Development and utilization of geothermal resources, the construction of geothermal greenhouse, both for the market to provide a large number of quality fresh vegetables off the market to ensure market supply, but also save energy, reduce vegetable production costs, improve economic and social benefits. We tested the performance of Dong Tang geothermal greenhouse from 1986 to 1988. The results show that: 1. The effect of laying geotextile increases the ground temperature. The upper part of the geothermal pipe, the closer to the ground pipe, the more obvious warming effect. Laying 6 to warm pipe ratio
