Warning of strong wind to greenhouse leek growers

At 1: 00 a.m. on October 20, a strong wind blew up in Hujiatuo Town, Laoting County, and the wind speed did not slow down until seven or eight o'clock that evening. As a result, many greenhouses, including leek sheds, were blown away, and the plastic films of more than a dozen greenhouses in our village were blown away, causing varying degrees of losses to vegetable farmers, and also sounding the alarm for all aspects of the management of leek sheds. Here, I have summed up the following experiences of Fangfeng for reference.

First, the plastic film of the leek shed should not be too economical.

This time, the scraped leek shed is mostly caused by the lack of enough plastic film to cover the shelves. Even if the earth is pressed around, when the strong wind comes, the plastic film shakes up and down, swaying for a long time, no matter where there is a leak, the whole shed of plastic film will be lifted instantly, and human strength is simply irresistible. So, what is the surplus of the plastic film in the shed? According to this lesson, it is found that there is a surplus plastic film of more than 40 centimeters outside the shed and added enough soil, and the plastic film at both ends of the shed has a surplus of more than 50 centimeters to press enough soil, which is safer.

Second, the edge of the shed had better be trenched and buried with plastic film.

Bury the plastic film in the ditch, the plastic film in the ditch will form a U-shaped, more soil, strong resistance to the wind. Many greenhouses that have not been scraped are trenched and buried.

The iron bar joint tied to the shed must not be screwed on the outside of the scaffolding

In general, the shed structure is connected by iron bars, and the interface screws of the iron bars had better be screwed on the inside of the cement pile or bamboo pole, so that they can not come into contact with the plastic film. Once the screwing comes into contact with the plastic film, not only the wind will grind the hole, that is, after the plastic film is compacted, the strong extrusion pressure will also make the plastic film outlet. If the buckle is facing outward, it is necessary to twist the buckle flat again, so that the contact surface with the plastic film is not too protruding, and then wrap it up with thicker old clothing cloth, so that it is better to touch the fulcrum that does not bulge with your hands, so as to avoid stabbing the film.
