大棚的前脸处及大棚拱度变化最大的地方，压膜绳、钢丝与棚膜产生摩擦，造成棚膜损坏，想过很多办法解决这一问题，可效果都不理想。

Shed before the face of the shed and camber change is the biggest, pressure film rope, steel wire and the films friction, causing damage of films, thought of many ways to solve this problem, but that effect is not ideal.

根据我协会专家多年的建棚经验，通过两种方法可以解决压膜绳与钢丝接触磨破棚膜的现象。

Based on the years of experience of the building of the foundation of my association, we can solve the phenomenon of grinding the film of the diaphragm by using two methods.

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。

Method a, pressure on membrane cord sets of plastic hose, the main purpose is to increase the contact area pressure membrane rope and the films, film rope and films friction, reduce pressure to reduce the breakage of the films. In the place where the arch is large, the pressure line may also be exposed to the steel wire on the ceiling, which will be worn by a small piece of cloth on the wire.

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 2: rope of bamboo density increase pressure membrane, farmers can be set in the pressure membrane rope place setting spacing of 10 centimeters or so between two bamboo poles, and then pressure membrane rope between two bamboo poles, thus limits the range of pressure film rope, at the same time can also avoid the rope with wire on the tent will shed film membrane worn out. But notice that the bamboo poles on either side of the membrane have to be polished, otherwise the bamboo slug will be worn out. To use a thick bamboo shed, if the installation after squeeze film rope, rope pressure membrane will not press films on steel wire, films torn chances will be greatly reduced, farmers can squeeze film rope can be installed directly.
