微薄塑料薄膜是一种厚度为普通塑料薄膜1/5～1/6的聚乙烯透明薄膜,目前长沙、北京、旅大、哈尔滨、无锡等地都已批量生产,一般厚度为0.015～0.02毫米。这种薄膜过去多用于旱地作物的地面复盖栽培,近年来也逐渐用于早稻育秧,可平铺也可支架复盖,效果和使用技术与普通塑料薄膜大体相仿。根据各地实践,用微膜育秧比普通的薄膜育秧有较多的优点。首先是,可以降低育秧成本。据江苏省高邮、泰州、吴县、宝应、
The thin plastic film is a kind of polyethylene transparent film whose thickness is 1/5 ~ 1/6 of common plastic film. At present, Changsha, Beijing, Luda, Harbin, Wuxi and other places have been mass-produced. The general thickness is 0.015 ~ 0.02mm. In the past, this kind of film was mostly used for the ground cover cultivation of dryland crops. In recent years, it has also been gradually used for rice seedling cultivation. It can be tiled or scaffold covered. Its effect and use technique are similar to ordinary plastic film. According to local practice, using micro-film seedling than ordinary film seedling has more advantages. The first is to reduce the cost of raising seedlings.
