科学选择棚(室)薄膜是设施蔬菜栽培获得优质高产高效的关键环节之一。生产上常用的棚膜种类可分为:耐老化无滴膜、耐老化有滴膜、多功能复合膜以及紫光膜等。 1、耐老化流滴膜 包括聚氯乙烯棚膜和聚乙烯耐老化流滴膜。薄膜透光性好、棚(室)内气温、地温高,水滴可沿薄膜内表面呈水膜状流下,棚(室)内湿度小,可减轻各种病害的发生和蔓延,可用于日光温室
Shed (room) film science is one of the key aspects of high-quality, high-yield and high-efficiency cultivation of vegetables in facilities. Production of greenhouse film types can be divided into: anti-aging drip film, anti-aging dripping film, multi-functional composite film and purple film. 1, anti-aging flow drop film, including PVC shed film and polyethylene anti-aging flow drop film. Film translucency, greenhouse (room) temperature, high ground temperature, the water droplets can be film along the inner surface of the film flow down, shed (room) humidity is small, can reduce the occurrence and spread of various diseases can be used in solar greenhouse
