For strawberries in greenhouse, special attention should be paid to anti-cold and anti-freezing work, new high-fat film should be sprayed in time to keep warm and frostproof; the film should be tightly sealed, pay attention to prevent strong wind from breaking, and straw curtains can be covered at night; if possible, a small shed can be built in the shed, double-layer thermal insulation protection.

two。 Loosen the soil and weed. The strawberry field must be loosened and weeded before overwintering in order to avoid winning glory, fertilizer and water between weeds and strawberries.
