棚架材料表面要光滑大棚薄膜破裂的主要原因是搭架大棚用的材料竹竿、铁丝、铝丝等硬而尖将薄膜戳破。因此,搭架材料一定要做到表面光滑,将竿尖、竹节削光磨平。扎架要选用麻绳、线绳等柔软材料。拼缝莫太窄大棚薄膜都是由若干窄幅薄膜拼接而成的,在拼接时要增大粘接面积,提高粘接强度。若拼缝太窄,粘接面积小,用力拉扯时就会造成脱缝。用线压住薄膜建大棚盖上薄膜后,应立即用压膜线压住。一般每隔1~2个棚架
Scaffolding material surface should be smooth Greenhouse film rupture is the main reason for scaffolding material bamboo pole, wire, aluminum wire and other hard and pointed film burst. Therefore, the scaffolding material must be smooth, the tip of bamboo, bamboo polished polished. Tie rack to choose hemp rope, rope and other soft materials. Patchwork is too narrow plastic shed film is spliced by a number of narrow-width film made in the splicing to increase the bonding area, improve bonding strength. If the patchwork is too narrow, the bonding area is small, when pulling hard, it will cause the seam. With the line pressure to build a film covered greenhouse film, the film should be immediately pressed line pressure. Generally every 1 to 2 scaffolding
