How to remedy seedlings after freezing
Once the green seedlings have been frozen, they should promptly take scientific measures to remediate the tree as soon as possible to restore vigor and reduce losses.
Plants that cause defoliation due to frost damage must be removed from the leaves in time to reduce the water consumption of the tree. After freezing, the cold-resistant ability of the tree is further reduced, branches are prone to sunburn, and measures such as the protection of trunks and soil cover should be done in time to reduce the harm of freezing damage.
Freezing damage to lighter plants, pruning can take the short side of the branch to update the main, in the bud before, in order to promote the new slightly. At the same time, it is necessary to apply fertilizer in time, apply thin fertilizers, use nitrogen fertilizer, or spray. 0.2% to 0.3% potassium dihydrogen phosphate mixture.
Plants with severe frost damage occur at appropriate levels according to the degree of frost damage. The branches are frozen, the reaction is slow, and the boundary with unfrozen branches is not easy to distinguish in a short period of time. Therefore, it should not be a big cut, so it is better to cut the dead parts in the early spring buds. Trimmed wounds should be coated with a protective agent or animal oil.
Dead trees should be cleared in time. After the frost damage, the wood and dead wood in the forest increase, which provides favorable environmental conditions for the development of the stem pests. Therefore, after the freezing disaster, the dead wood and its branches in the forest should be promptly cleaned.
