First, slowly warming up. After the shed vegetables are frozen, the shed can not be warmed quickly. The venting should be strengthened to make the shed temperature rise slowly, so that the frozen tissue gradually absorbs the water lost by freezing, promotes cell reactivation, and reduces tissue death.
Second, spray a new high-fat film. A new high-fat film can be sprayed with a sprayer to increase the humidity of the air in the shed, stabilize the temperature inside the shed, and restore the vitality of the frozen tissue.
Third, pruning. After being frozen, cut off the tender leaves of the frozen shoots in time. Even if the seedlings are frozen, the pepper seedlings can also germinate the side branches, take one of the strong branches instead of the main stem, and cut off the remaining side branches. After the pruning of the frozen celery in the open field, new leaves can also be germinated.
Fourth, improve disease resistance. After the plants are frozen, the pests and diseases are easily taken in. The plant cell immune factors should be sprayed in time to enhance the plant's stress resistance, and the viral DNA can be broken and apoptotic. Strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote positive energy ecological growth of plants.
