长江流域各省,常因低温造成越冬花卉大量死亡。我们设计了一个不需加温的简易温室,冬季室温稳定保持在10℃以上,培养的紫罗兰,扶桑等生长旺盛、枝叶繁茂。这种简易温室,用材少、造价低,便于普及推广。温室选在背风向阳,地下水位低的地方,宽4米长7米,先在两边挖掘出50厘米深的沟,再按花盆大小,由两边向中央挖成梯坎,最低处为走廊。在上部盖成屋顶,房顶双层,层间相距20厘米,各加盖一层薄膜,上层薄膜需粘结成
Provinces in the Yangtze River Basin, often due to low temperatures caused a large number of overwintering flowers died. We designed a simple greenhouse without warming, stable at room temperature in winter to maintain above 10 ℃, the cultivation of violets, hibiscus and other vigorous growth, lush foliage. This simple greenhouse, with less timber, low cost, easy to popularize. Greenhouses in the leeward sunny, low groundwater table, 4 meters wide and 7 meters long, first excavated on both sides of 50 cm deep groove, then press the flower pot size, dug into the ridge from both sides of the central ridge, the lowest corridor. In the upper cover into a roof, roof double, 20 cm apart from the layers, each stamped with a thin film, the upper film to be bonded
