渗水塑料薄膜
Abstract:
本发明公开了一种渗水塑料薄膜,由两层塑料薄膜组成,一层薄,一层厚,每层塑料薄膜上,每平方米开400－800个直径为3－5毫米的孔,两层粘贴,粘贴线为十字交叉矩形,孔为错位排列,厚层膜为渗水塑料薄膜的正面,用做大棚和地膜使用时,雨水会自动从薄膜孔中向下流淌,天晴太阳照射下,地表水蒸汽会使两层薄膜贴紧,保持住地表的水分。本发明适用于我国北部、西部干旱缺水地区的种草植树,可提高植物的成活率。
Abstract(English):

The permeable plastic film consists of two, one thin and ond thick, layers of plastic film with 400-800 holes in 3-5 mm diameter per square meter area. Two layers of film are crossed and adhered withthe thick layer is outside one. When the permeable plastic film is used in green house and as mulching film rain water will flor downwards through the holes in rainy day, and the two layers are made to close each other by the vapor from the surface of soil to maintain moisture is sunny day.
