农用薄膜是用途广泛的塑料保护膜,经常被用来覆盖在土壤表层或应用于温室大棚中。有了农用薄膜的保护,土壤内部温度得以提高,土壤中的营养成分得以维护,野草生长速度得以抑制,种子发芽率得以保证。此外,农用薄膜还能有效地保护农作物免受太阳紫外线的辐射。根据用途的不同,农用薄膜主要可分为以下三大类:棚膜、地膜及饲草膜。目前,市面上农用薄膜主要以PE、PVC、EVOH(聚乙烯醇)等为原料。其中,LLDPE和LDPE薄膜在整个农用薄膜市场中占据大的份额。知名市场调研机构Researchand Markets日前发
Agricultural film is a versatile plastic protective film, often used to cover the surface of the soil or in greenhouses. With the protection of agricultural film, the internal temperature of the soil can be increased, the nutrients in the soil can be maintained, the growth rate of weeds can be suppressed, and the seed germination rate can be guaranteed. In addition, agricultural films can also effectively protect crops from the sun’s ultraviolet radiation. According to different uses, agricultural film can be divided into the following three categories: film, film and forage film. At present, the market mainly agricultural film PE, PVC, EVOH (polyvinyl alcohol) as raw material. Among them, LLDPE and LDPE film in the entire agricultural film market occupies a large share.
