菜农新建大棚或改造大棚，采用了新的压膜方法
当前新建大棚棚面骨架采用的多是镀锌钢管焊接或一体液压而成，俗称钢筋铁骨。而菜农在安装前，一般会在钢管上端焊接一块W型的连接件，安装时把钢管的连接件直接卡槽到后砌柱子上，最后再用铁丝加以捆绑固定。确实，这样做，能保持钢架最大的稳定性，但是却暴露出一个缺陷，在上膜时，容易划损薄膜，缩减薄膜的使用寿命。同时，为了防风，还得重新设置压膜绳，非常麻烦。
At present, the framework of the newly-built shed surface is mostly made of galvanized steel pipe by welding or integrated hydraulic pressure, commonly known as steel ribs. Before the installation, the vegetable farmers usually weld a W-shaped connector on the upper end of the steel pipe. During the installation, the connector of the steel pipe is directly clamped on the post, and then tied and fixed with iron wire. Indeed, this can maintain the maximum stability of the steel frame, but it exposes a defect. When the film is applied, it is easy to scratch the film and reduce the service life of the film. At the same time, in order to prevent wind, it is also necessary to reset the film pressing rope, which is very troublesome.
不少菜农新建大棚或改造大棚，采用了新的压膜方法，那就是直接应用卡槽杆。这种卡槽杆不仅对薄膜保护不少，而且完全替代压膜绳，效果不错。
Many vegetable farmers have adopted a new method of pressing film, that is, directly using the card slot pole. The utility model not only protects the film, but also completely replaces the film pressing rope with good effect.
