Conditions can be increased by heating facilities such as infrared lamps.

(3) Appropriate irrigation and spraying of the top dressing outside the shed. 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.

3, Qinggou drainage, prevention and control of stagnant water within the strawberry greenhouse.

In addition, fruit growers in various parts of the country have to shake the snow on the tree before the snow is frozen (frozen) and shake the snow. The snow can be shaken.
