Early prevention and early management For vegetable fields that can be cultivated, when low temperature, snowfall, freezing or cold currents arrive, the soil can be cultivated next to the vegetable roots through field tillage to effectively loosen the soil, prevent frostbite of the root system, promote root growth and ensure root vitality. Before the cold wave or rain and snow, you can use plastic film, non-woven fabric or sunshade nets to cover and prevent the cold; after the cold wave, continue to strengthen the cover to delay the freezing and thawing process, and prevent the vegetables from freezing damage. In winter, the groundwater level is high. In rainy and snowy weather, the soil humidity increases. Vegetables in the field, especially open-field vegetables, are prone to retting, dead seedlings, and rotten vegetables. Clean the ditch in time to prevent strong plants in the field. Before the arrival of cold currents, rain and snow, the leaves can be sprayed with chitin, alginic acid and other complete nutrient foliar fertilizers and plant-derived growth regulators. After the snow disaster, we must strengthen the Vegetable management, clear snow in the fields in time, and clear away Ditch, drainage, cultivating, reduce soil moisture and reduce the occurrence of waterlogging. For some fields with low-lying terrain, long ridges, and poor drainage, waist ditches must be added to drain and drain the soil. For heat preservation and antifreeze vegetables, non-woven fabrics, old plastic films, straw curtains, sunshade nets, etc. can be used to cover and keep warm at night to prevent freezing damage. Plastic film covering and heat preservation should be covered by a small arch shed. Non-woven fabric covering and heat preservation should adopt floating surface covering method. Reasonable fertilization and appropriate topdressing of phosphorus and potassium fertilizers, 0.2% potassium dihydrogen phosphate can be sprayed on the leaves to improve the cold resistance of plants and promote crops to resume growth as soon as possible. Before and after rain and snow, the vegetables that can be harvested on the market should be harvested in time to reduce losses.
