在高寒地区冬季种植蔬菜过去都是用玻璃温室,塑料薄膜、胶片搭盖的温室也只能在春、夏、秋季用,不适合冬季种植蔬莱。为了解决这个问题,海拉尔皮革厂五七农场技术人员潘长杰经过反复多次实验,终于搞成了塑料板材温室。通过对比试验,用聚丙乙稀板材代替玻璃搭盖温室,不仅解决了玻璃短缺问题,而且有以下五个优点: 一、塑料板材温室在同样的条件下比玻璃温室的温度高5℃至7℃。二、损失小,成本低。由于玻
In the alpine region in the winter planting vegetables are used glass greenhouse, plastic film, film covered greenhouse can only be used in spring, summer and autumn, not suitable for winter planting vegetables. In order to solve this problem, Pan Changjie, a technician from May 7 Farm in Hailaer Tannery, has finally become a greenhouse of plastic sheet after repeated experiments. Through the comparative test, polypropylene sheet instead of glass to cover the greenhouse, not only solved the problem of glass shortage, but also has the following five advantages: First, the plastic sheet greenhouse under the same conditions than the glass greenhouse temperature 5 ℃ to 7 ℃ . Second, the loss of small, low cost. Due to glass
