Reasonable trimming. After freezing, remove the frozen and non-shedding leaves in time to avoid further absorption of water and increase frost damage. Do not cut off the frozen and dried branches immediately. It should be cut shortly after the spring and death of the buds. Strengthen management and restore the canopy as soon as possible.
Add fertilizer and expand the hole to change the soil in time.
In the spring, fertilization can be carried out early, with organic fertilizer as the main factor, and the amount of fertilizer should be increased appropriately to promote the shoots, and after the new shoots are spread, 1-2 root dressings are carried out. For fruit trees whose roots are still normal after freezing, deep trenches can be dug between plants or rows, and weeds, turf soil, fire-burned soil, cake fertilizer, etc. can be layered to promote new roots.
Protect the branches and pay attention to pest control.
The frozen fruit trees are weak, and they are susceptible to daily burning and infection with resin. The branches should be painted with lime paddles, and the pests and diseases should be sprayed in time to ensure the healthy growth of shoots and leaves, and the ability to restore results as soon as possible.
