The so-called shed is to put all the sheds on the shed as if they were at night, but it is not set up during the day. It is only half a meter high in front of the face, letting the sun shine in, so that the leeks can grow slowly and grow slowly. At one point, just when the soil is opened, the leeks can grow to more than 20 centimeters in height. When they have the ability to withstand cold, they can lift the plastic film on the shed and wind the curtains as soon as possible. However, this sudden strong wind blew the grass curtains down, some straw curtains crossed each other, and some were blown directly under the sheds, which caused great trouble for management.
First of all, looking at the weather forecast every day, as soon as there is a windy and snowy forecast, the curtains are rolled up in advance. The curtains that are rolled up stand on the roof and the wind can't wipe the big bundle of curtains. In addition, the second layer of plastic film that has been prepared for a long time (wrapped on a straw curtain in winter and also used in snow) is pulled down in advance, and the wind is blocked by the plastic film. The grass curtain under the plastic film will be Safe and sound.
Therefore, to remind the sauerkraut growers that in the spring windy season, we must be prepared to reduce unnecessary troubles.
