There is no omission in the windproof room

When the windy weather is encountered, the ventilation outlet of the greenhouse must be shut tightly so that the cold air will not be directly blown into the shed from the air vent to damage the seedlings. When using a three-wheeled rope room, pay attention to the rope inside the shed. Outside the shed, the shed must be kept firmly fixed. If the soiled bag is not firmly pressed, the grass shed on the shed can be placed under the bleeder outlet. It was scratched and affected the growth of vegetables in the shed.

The film should also be well protected. If windy weather is known ahead of time, when installing the roller blinds in the booth, when the grass is pulled in the daytime, the film can be rolled into the grasshopper. This prevents the film from being swayed by the wind. For sheds without security shutters, after the drafting is done during the daytime, the film can be rolled up and compacted with sandbags and other coverings to prevent it from being blown by the wind. After laying grass in the evening, be sure to cover the membrane and press the membrane well.

In addition, in the booth where the shutter is not installed, in the evening, when the grass is placed, care must be taken to prevent the grasshopper from being blown by the wind. A few households can cooperate with the grasshoppers, a shed can be placed on the grass, and a shed is fixed in the middle. Hey, the next one is fixed. When installing the shutter room, the vegetable farmers should pay special attention to the wind direction, and pay attention to pressing the bricks and mortar on both sides of the greenhouse.
