方法一，在压膜绳上套塑料软管，这样做的主要目的是增加压膜绳与棚膜的接触面积，减小压膜绳与棚膜摩擦力，从而大大降低棚膜的破损。在拱度大的地方，压膜绳还可能与大棚上的钢丝接触，将棚膜磨破，可在此处钢丝上缠一块小布条。

A method, in the film on the rope set of plastic hose, the purpose of doing this is to increase the contact area of the film and film pressing rope, the rope and the friction film film decreases, thereby greatly reducing the damage of films. In the arch of the place, may also contact with the steel wire rope are shed, the film can be worn, where wire wrap a piece of cloth.

方法二：增加压膜绳处的竹竿密度，菜农可以在设置压膜绳的地方设置间距10厘米左右的两根竹竿，然后将压膜绳压在两根竹竿之间，这样就限制了压膜绳的活动范围，同时也能避免压膜绳与棚上的钢丝将棚膜磨破。但是要注意，压膜绳两侧的竹竿上的竹节必须打磨平滑，不然竹节也会将棚膜磨破。对于使用较粗竹竿的大棚，如果安装压膜绳后，压膜绳不会将棚膜压到钢丝上，棚膜磨破的几率就会大大降低，菜农可以直接安装压膜绳即可。

Method two: to increase the density of bamboo laminated rope, two pole farmers can be set in place of film pressing rope spacing of about 10 cm, and then squeeze pressure in the rope between two poles, thus limiting the film pressing rope range of activities, but also can avoid the wire rope and the film studio films will be worn. But note that film on both sides of the bamboo bamboo rope must be polished smooth, or bamboo will film at. For the use of thick bamboo shed, if you install the film pressing rope, rope will not be pressed to squeeze film wire, film worn probability will be greatly reduced, farmers can be installed directly to film pressing rope.
