美国农业部集约化农业研究室设计了一种能自供能量且高度节水的新型温室。这种温室的顶棚是双层的,两层之间的间隔除了保暖隔热和透气以外,还可以把农作物蒸发的水加以过滤,只排除干燥的废气,其冷凝水顺着收集槽流下汇集起来,加上营养物质可循环使用,其用水 The USDA Intensive Agriculture Research Laboratory has designed a new type of greenhouse that is self-sufficient in energy and highly water-saving. The roof of this greenhouse is double-decked, with the exception of thermal insulation and ventilation between the two layers, which filters the water evaporated by the crops and removes only the dry exhaust gases, condensing water flowing down the catch basin , Plus nutrients can be recycled, its water
