①在棚面多加强在压膜绳的密度和方向，提前关闭防风口，检查棚膜的张弛度。

In the shed surface strengthen in the density and direction of pressing rope, closing anti air, check the relaxation of the film.

②风口使用摩擦力较大的放风绳或增加放风绳的密度就能取得很好的防风效果。因为春季风大，放风口被吹合，导致棚内温度过高，会影响蔬菜生长。所以应增加防风绳的密度。

The use of air leaked larger or increase the density of rope friction can be leaked rope get wind effect is very good. Because the spring wind is blowing, the air discharging port, resulting in temperature is too high, will affect the growth of vegetables. Therefore, the density of windbreak rope should be increased.

同时放风绳最好使用摩擦力较大的宽布条为好，因为这种布条在打活结固定棚膜时，绳子的摩擦力较大，活结不容易被大风吹松，导致放风绳松开，使放风口闭合。而对于使用尼龙绳作为防风绳的，因为这种绳的摩擦力较小，则要适当增加尼龙放风绳的密度，并将其固定好，以防风口被风吹合。

At the same time. It is best to use wide cloth rope friction larger as well, because this kind of cloth in fixed film tied in a slipknot, rope friction is large, not easy to slipknot was blown loose, resulting in leaked rope is loosened, the outlet is closed. But for the use of nylon rope as the wind rope, because less friction this rope, nylon rope is appropriate to increase the density of air, and fixed, to prevent the air blown together.

③同时还要注意在大风天气时随时进行检查，防止放风绳松动，风口闭合。

At the same time, but also pay attention to check at any time in windy weather, to prevent leaked rope loosening, outlet closure.
