When people must leave the shed, the next day, the film must be lifted outside the shed to open the film and open the shed in time. Conditions can be increased by heating facilities such as infrared lamps.
(3) Appropriate irrigation in the shed and spraying of the topdressing fertilizer. When strong cold air arrives, proper irrigation and spraying of phosphorus and potassium fertilizers in the shed enhance the cold-resistance of the plants and reduce freezing damage.
