Covering materials can be used *** crop stalks, leaves, soft grass, decomposed horse manure, finely broken ring loam, etc. If you use soil to cover the cold, you should first cover a small amount of grass and then cover the soil to avoid damage to strawberry seedlings when the soil is removed in spring. The thickness of the covering is determined by the local weather conditions and the insulation performance of the covering material, and the thickness is generally 3 to 5 cm. Covering method Covering is done in two times. After pouring the frozen water, dry it slightly, and cover a part of the material first. After a few days, when the temperature does not rise again, cover it completely. Set up wind barriers to prevent cold In densely planted strawberry gardens with stable snow, wind barriers can be erected to prevent cold without ground cover. Wind barriers are set every 10 to 15 meters, and materials such as sorghum stalks, corn stalks, and reed mats can be used. The barrier height is 2~2.5 meters. If conditions permit, use materials such as cold-proof cloth and color steel tiles to set up wind barriers around the garden, and the effect is also very good. The cover removal period is generally divided into two after the beginning of thawing in the spring of the following year. For the first time, when the average temperature is higher than 0℃, remove the thawed cover. In the case of excessive rain and snow in winter, it must be removed in time to promote the thawing of the lower layer, which is conducive to sunlight and raises the ground temperature. The second time is when the strawberry is about to germinate. Do not remove the cold protection too late to avoid damage to the new stem. Use mulch film to cover the strawberry after pouring the frozen water with the mulch film, and then cover it in the direction of the border when the surface is slightly dry and flat. Tighten the mulch film when mulching, spread it flat so that the mulch film is close to the border surface, press tightly around the film, and cover the middle with a small mound to prevent the wind from blowing through the film, and then cover it. Or in areas with snow, it is better to cover strawberries with 10 cm thick wheat straw, thatch, straw and other materials and then cover with plastic film than to cover with mulch and then with mulch.

Strawberries enter dormancy in winter. Due to the shallow root system of strawberry, it can only tolerate a low temperature of -8°C and a temperature of -10°C for a short time in winter. If the temperature drops again, freezing damage will occur. In severe cases, the plant will die, resulting in a decline in economic benefits. Therefore, we must take good measures to protect strawberries from overwintering and cold. In the north, cover and heat preservation methods are used to prevent cold and moisture, which is beneficial to the growth of strawberries. However, if the mulching effect is not good, it will show late budding, weak growth, and significantly lower yield.
