Apple should be promptly remedied by frost damage
First, for all apple trees with frozen trunks and complete roots, the ground can be sawed off. From March to April of the following year, we grafted again using splicing or subcutaneous grafting. If the trunk of the sapling is chilled, the saplings can be re-emerged, leaving a robust sprout and reculturing the tree.
Second, if the tree trunks account for more than half of the apple trees, they are bridged on the frozen side. Serious damage must be re-grafted.
Third, the lighter damaged apple trees, before germination, spray 100 times more effective rot against rot. After germination, the dead bark was scraped off and coated with 843 rehabilitant or rot star liquid. During the apple tree growth period, the branches are sterilized by treating rot disease agents such as 9281 and tebuconazole for two weeks. 7 to 10 days after the leaf is sprayed, a small amount of urea is sprayed with vital acid and sprayed 4 to 5 times. In the pruning, in addition to cutting off the frozen dead sticks, the wound should be reduced as much as possible, and the principle of light shearing should be used to slowly put part of the shoots and retract the extended branches to extract the Wang branch.
Fourth, the apple bud victim, the top bud, side buds were all frozen, to increase the amount of fertilizer, timely water supply, promote budding, bud germination, re-cultivation Zhizu.
