Remedies for frozen vegetables
Due to the influence of strong cold air or cold waves, winter vegetables are prone to low-temperature and freezing damage and affect the economic income of vegetable farmers. Here are some remedial measures after freezing: First, slowly warming. After the shed vegetables are frozen, they should not be warmed up quickly. The release of winds should be strengthened so that the temperature of the sheds can be slowly increased. The frozen tissues can gradually absorb the water lost due to freezing and promote the revival of the cells and reduce the death of the tissues. Second, shade sun. For vegetables that have been frozen, pay attention to shading and avoid direct sunlight, so as to avoid dehydration and shrinkage of frozen tissue. Generally covered at high temperatures at noon. Other times can be partially covered so that the shed maintains a suitable temperature and humidity environment. When the frozen tissue is rejuvenated, the shade can be gradually reduced. Third, chase fast-effective fertilizer. After the frozen vegetables are recovered from the slow seedlings, the available nitrogen fertilizer and phosphorus and potassium fertilizers can be topdressed in time to promote the growth of the vegetable plants, and then sprayed with 2% urea solution or 0.2% potassium dihydrogen phosphate solution. Fourth, artificial water spray. The sprayer can be used to spray water, increase the air humidity in the shed, stabilize the temperature in the shed, and allow the frozen tissue to recover its water. Fifth, irrigation insulation. Winter vegetables are mostly caused by water shortage due to freezing injury. Because the specific heat of water is higher than that of air and the heat dissipation is slow, sufficient water can be poured before freezing or the weather can be filled with enough water in winter to prevent freezing. The irrigation of horse water or watering of the frozen vegetables can increase the heat capacity of the soil and prevent the ground temperature from continuing to fall and reduce the freezing damage. After watering, pouring enough water, watering or watering, grasp the favorable period when temperature rises, and loosen soil to keep warm. Six, pruning. After being frozen, timely cut off the young shoots that have been frozen to death. Even if the seedlings of the pepper seedlings are frozen, the side branches can be germinated well. Take one of the strong branches to replace the main stem and cut off the remaining side branches. Fresh pruned celery after pruning in the open field can also germinate new leaves. Seventh, grab the seed and rush to broadcast. In order to reduce economic losses, cold-resistant spinach, Chinese cabbage, radish vegetables, and lettuce can be planted after the weather warms up. It is best to rush in the middle and small sheds, early emergence, early growth. Eight, prevention and pest control. After the plants are frozen, the pests and insects can easily enter the house. Sprinkle some protective agents and pest control insecticides in time.
