Remedial measures after shed vegetables are frozen

　　 1. Irrigation and heat preservation: Irrigation can increase the heat capacity of the soil, prevent the low temperature from falling, and stabilize the near-surface atmospheric temperature, which is conducive to the steady rise of temperature and the recovery of the frozen tissue.

 

　　 2 , wind and cooling: After the shed vegetables are frozen, they can not immediately close the shed to heat up, only the wind can be cooled, so that the temperature in the shed slowly rises, avoiding the steep rise of the frozen tissue.

 

　　 3 , artificial water spray: water spray can increase the air temperature in the shed, stabilize the shed temperature, and inhibit the evaporation of water from the frozen tissue, and promote tissue water absorption.

 

　　 4 , cut off the dead branches: timely cut off the frozen stems and leaves, in order to avoid tissue mildew lesions, induced disease.

 

　　 5 , set up a shed: cover the shed in the shed to prevent the frozen vegetables from being exposed to direct sunlight, so that the frozen tissue loses water.

 

　　 6. Replenishing fertilizer: After manual planting, the fertilizer should be applied and sprayed with 2% urea solution or 0.2% potassium dihydrogen phosphate solution.

 

　　 7. Pest control: After the plants are frozen, the pests and diseases are easily taken in. The protective agents or agents for preventing and treating diseases should be sprayed in time.
