The seedlings and weak seedlings grown in greenhouses are poor in cold protection and can be covered with a layer of sheds on the vegetable larvae. Double protection can effectively prevent freeze damage to the seedlings. Cover grass curtains. Straw stalks are woven into the straw and covered at night (rolling up the straw in the daytime), which can slow down the heat in the shed, block the frost, and protect the shed film. Irrigation before frost can increase soil and air temperature in the shed. Because the heat capacity of the water is relatively large, even if the temperature outside the shed is in cold winter, the seedlings of fruits and vegetables within the shed can grow normally. If the area of ​​the greenhouse is small, hot water can be placed in the shed before the cold wave arrives, and the water vapor will be slowly distributed, so that the temperature inside the shed will rise and play an anti-freeze effect. When the weather forecast is frosty, smoke can be expelled from the shed outside the night to increase the temperature around the shed and the temperature inside the shed can also increase.
