在日光温室的建造和利用过程中,我们对天窗通风口进行了改造,在作物大行中采取了挖沟垫草技术。现介绍给大家。 一、天窗风口固定形式的改进 日光温室的天窗应设在建筑物的最高处,有利于排放湿热空气,在冷凉季节一般只用天窗通风换气,所以天窗开放得特别多。前几年最常用的方法是“开膛破肚”通风法,即在大棚顶上纵向开一道长缝,缝的长短宽窄及开放时间随当时的温湿度灵活掌握。这种方法使用起来很方便,但它有一个致命的缺点,就是当做风口的那部分棚膜由于上下拉来拉去,影响到整个大棚容易松动,一旦刮起大风,棚膜上下抖动,很容易
In the solar greenhouse construction and utilization process, we have modified the skylight vents, trenching and paddling technology in the big crop of plants. Now introduced to everyone. First, the fixed form of the roof window tuyere Sunroof greenhouse sunroof should be located in the highest point of the building, is conducive to the discharge of hot and humid air in the cold season generally only use the skylight ventilation, so the skylight was particularly open. A few years ago the most commonly used method is “broken belly” ventilation method, that is, in the roof to open a longitudinal longitudinal slit, the length of the slit width and opening time flexible with the prevailing temperature and humidity control. This method is very easy to use, but it has a fatal flaw, that is, as part of the vents of the film due to pull up and down to pull, affecting the entire shed easily loose, once the wind blowing, the film shaking up and down, it is easy
