隔行固定钢丝压膜方式
Film pressing method of interlaced fixed steel wire
这是目前多数拱棚采取的压膜方式。隔行固定即使用压膜竹竿对棚膜进行固定时，每隔一根主骨架固定一行，然后使用钢丝压膜。有的菜农可能会在拱棚顶端间隔的这一行主骨架上额外附加两根短竹竿进行固定。这种固定方式的优势是用于固定的压膜竹竿相对较少，对棚膜的破坏面积较小，最大程度的保护了棚膜。同时提高了棚室光照。
This is the film pressing method adopted by most arch shed at present. When interlacing, even when the film is fixed by a bamboo rod, one row is fixed by every other main skeleton, and then the film is pressed by steel wire. Some vegetable farmers may attach two short bamboo poles to the main skeleton at the top of the arch. The advantage of this fixing method is that the bamboo poles used for fixing film are relatively small, the damage area of the film is small, and the film is protected to the greatest extent. At the same time, the illumination of the shed was improved.

Using the characteristics of poor extension of steel wire, the greenhouse film was firmly fixed. It compensates for the fluctuation of shed membrane caused by interlaced fixation. The disadvantage is that the friction between the steel wire and the skeleton at the edge of the arch shed when the steel wire is tensioned will cause damage to the shed film, and the framework of the shed room will be more prominent when the shed film is compacted, otherwise it will pose a threat to the shed fil
