一、建简易温室 根据地形因地制宜建单坡式或弓型式塑料棚温室。单坡式采用座北朝南,南北宽5—6米、北墙高3米、南墙0.3米,两头山墙呈斜角形,在东山墙留门,西山墙留通风换气孔(直径40厘米)。弓型式:采用南北长、东西宽5—6米,形如蔬菜大棚,但必需盖双层顶,内层用耐低温、透光好、保温好的无滴水薄膜,外层用夜晚散热高的聚乙烯薄膜作双层棚
First, the construction of simple greenhouse according to the terrain according to local conditions to build a single slope or bow-type plastic shed greenhouse. The single-slope adopts the south facing south, 5-6 meters wide from north to south, 3 meters high on the north wall and 0.3 meters on the south wall. The two gables are beveled at the east wall, leaving ventilation holes (40 cm in diameter) . Bow type: North-South long, east-west width of 5-6 meters, shaped like a vegetable greenhouse, but must cover the double top, the inner with low temperature, good light transmission, good insulation without dripping film, the outer layer with high night cooling Polyethylene film for double shed
