After a few frosts on strawberry, before the outside temperature drops to -7°C, it is necessary to cover the cold warmth in time to make it safe in winter in the field. Cold and warm methods are provided with wind barriers, cover grass, buried soil and pressure manure. In the densely planted strawberry garden, wind barriers can be provided every 10-15 meters, and the corn stalks can be used as wind barrier materials with a height of 2.5 meters. In strawberry gardens with wide banded colonization or wide banded colonization, stalks of straw can be used to cover the cold, with a thickness of 8-10 cm. The newly planted strawberry garden can also be covered with cold and the soil thickness is generally 2-3 cm. However, if the lines are too narrow or the soil is too viscous, it is not appropriate to use a pressure soil method to keep it warm. After the thawing of the soil in the following year, the cover was uncovered for early spring management.
