1、拼缝莫太窄

1, the spelling is too narrow

大棚薄膜都是由若干窄幅薄膜拼接而成的，在拼接时要增大粘结面积，提高粘结强度。若拼缝太窄，粘结面积小，用力拉扯时就会造成脱缝。

The film is made of a series of narrow films, which will increase the bond area and increase the bonding strength. If the seam is too narrow, the bonding area is small, and the tension will cause the parting.

2、用线压住薄膜

Use wire to press the film

建大棚盖上薄膜后，应立即用压膜线压住。一般每隔1~2个棚架拉一道压膜线，线的松紧要适度，同时在迎风一面设立简易防风障。否则，既薄又轻的大棚薄膜在冬季大风的袭击下很容易被吹破，甚至被大风卷起。

After the film is built, it should be pressed under the pressure membrane immediately. In general, every one to two pieces of shallows are pulled together with a membrane line, which is moderately elastic, while creating a simple anti-wind barrier in the windward. Otherwise, the thin, light canopy films can easily be blown apart in the winter wind, even rolled up by the wind.

3、薄膜破损及时修补

3, film damage is repaired in time

薄膜在使用和保存过程中容易破损，使用中破损可采用临时修补方法，方法有三：

The film is easy to break in the use and preservation process.

一是水补法，把破损处擦洗干净，剪一块比破损地方稍大的无破洞的薄膜，蘸上水贴在破洞上，排净两膜间的空气，按平即可。

Is a water filling method, scrub the affected area is clean and cut a little older than my broken place no hole in the thin film, dipped in water on the hole, clean the air between the two membranes, according to the flat.

二是纸补法，农膜轻度破损，用纸片蘸水后趁湿贴在破损处，一般可使用10天左右。

The second is the paper patch, the agricultural film is mild, and the paper is dipped in the water and then applied to the broken area, which can be used for about 10 days.

三是糊补法，用白面加水做糨糊，再加入相当于干面粉重量1/3的红搪，稍微加热后即可用来补膜。

The third is the paste method, the paste is made with white flour and water, and then the red honing is equivalent to a third of the weight of dry flour.
