摘 要:选择12种日光温室覆盖棚膜,在周年覆盖过程中,对不同薄膜透光性、升温保温性、耐候性及低温季节的防雾流滴性进行测试和综合比较。结果表明:PVC膜的多项主要性能指标优于其他参试薄膜,最适合北方高寒地区越冬周年生产,其次是多功能E-VA膜和PE膜,而普通的EVA膜和PE膜不适于高寒地区日光温室越冬生产。Twelve kinds of plastic films of solar greenhouse were used for selection in this experiment. As covering on the greenhouse in the whole year, their light penetration,temperature increasing and preservation, climate endurance and prevention from mist and water drops were compared. The results showed that the PVC film was better than other films joining the experiment in most of the indices of important properties, and therefore it is the most suitable one to be used in the over winter whole year production in the cold northern region. The next better ones are the muhifunctional EVA film and PE film, but the common EVA film and PE film do not suit the deep cold region production.
