新疆光热资源丰富,但早春和晚秋常有霜冻危害,无霜期160天左右。因春秋两季热量不足,限制了作物生长和产量的提高。为了探索一种省工、节能、成本低、效果好的防寒保温设施,经过几年的试验、对比观察,设计出组合式球面充气塑料薄膜拱棚。 1.结构设计 组合式球面充气塑料薄膜拱棚是将两层塑料薄膜,按一定规格(可根据棚架的大小而
Xinjiang is rich in light and heat resources, but frost damage often occurs in early spring and late autumn, and frost-free period is about 160 days. Due to lack of heat in both spring and autumn, crop growth and yield increase are limited. In order to explore a saving workers, energy saving, low cost, good cold insulation facilities, after several years of experiments, comparative observation, designed composite spherical inflatable plastic film arch shed. 1. Structural Design Composite spherical inflatable plastic film arch shed plastic film is two layers, according to a certain specification (according to the size of the scaffolding
