The remedy of cucumber after freezing
1. Irrigation insulation. Irrigation can increase the heat capacity of the soil, prevent ground temperature from declining, and stabilize the near-surface atmospheric temperature, which is conducive to the steady rise of temperature and the recovery of frozen tissue. 2. Exhale cooling. After the cucumber is frozen, it cannot be heated immediately by closing the canopy, and only the air is allowed to cool down, so that the temperature in the shed can rise slowly, and the frozen tissue can be prevented from necrosis when the temperature suddenly rises. 3. Artificial water spray. The water spray can increase the air humidity in the shed, stabilize the temperature of the shed, and prevent the water escaping from the frozen tissue from evaporating, which promotes the water absorption of the tissue. 4. Cut away dead branches. The frozen stems and leaves are cut off in time to prevent tissue damage and induce disease. 5. Shelter shade. Covering the shed in the shed can prevent the frozen cucumbers from being exposed to direct sunlight and dehydration of the frozen tissue. 6. Make up fertilizer material. After the thawing of the frozen plants, the quick-acting fertilizers should be chased and sprayed with 2% urea solution or 0.2% potassium dihydrogen sulfate solution. 7. Disease prevention and pest control. After the plants are frozen, the pests and insects can easily take advantage of them, and some protective agents and insecticides should be sprayed in time.
