How should winter greenhouse strawberries be managed to overwinter successfully?
In winter, greenhouse strawberries must be protected against the cold so the plants can overwinter successfully, preventing the plants from freezing to death and affecting yield.
1. Do a good job of freeze protection and insulation. For greenhouse strawberries, special attention must be paid to cold resistance and freeze protection, and New High Lipid Film should be sprayed in time for insulation and freeze protection; the film should be tied tightly and sealed firmly, taking care to prevent strong winds from tearing it, and straw curtains, etc. can be added at night; where conditions allow, a small tunnel can be built inside the greenhouse for double-layer insulation and protection.
2. Loosen the soil and remove weeds. Before overwintering, the strawberry plot must be loosened and weeded to avoid weeds competing with strawberries for light, fertilizer and water.
3. Strengthen field management of overwintering crops. Strawberries have relatively high water requirements, the soil should be kept moist at all times, and watering should be done in time during drought. Spray Caiguo Zhuangdiling at the appropriate time to enhance pollen fertilization quality, strengthen the cyclic fruit-setting rate, and promote fruit development. Strawberries are also not tolerant of waterlogging, so when the soil becomes waterlogged during rainy weather, drainage should be carried out in time.
4. Winter cold protection. Strawberries have relatively strong cold tolerance, but they fear cold wind. After watering the freezing water, wheat straw, rice straw, grass bags, leaves, film, etc. can be spread over them, and further spraying of Hushu Dajiangjun can provide insulation and freeze protection, protecting the flower buds through winter from freeze damage.
5. Timely prevention and control of pests and diseases. Strawberry diseases include viral disease, yellows, gray mold, bud blight, powdery mildew, snake eye disease, etc. They should be prevented in time according to plant protection requirements. Targeted pesticides can be sprayed together with a 800-fold dilution of New High Lipid Film to enhance pesticide efficacy, improve the utilization rate of the active ingredients, and consolidate the control effect.
