First, postponing the pruning period due to freezing of the trees in the early spring after the temperature rises, the frozen branches will continue to dry down, at the same time, the spring shoots than the unfrozen years later, it should be budding in the spring, live and death boundaries clearly Prune, short cut dry branches, and make a cut after the spring shoots. For the wounds, especially the big wounds, they should be scraped and shaved, and the protection must be strengthened to promote healing. The disadvantage of pruning prematurely by frozen trees is that too many wounds can easily cause infection, and that after cutting, the frozen and dry parts will continue to expand downward and aggravate injuries. After sprouting and cutting, the buds will sprout at the cutting point, which will absorb water and nutrients from the buds and send water and nutrients upward to the branches. This will prevent the cuttings from falling to death.
Second, early removal of frozen dead leaves of frozen citrus fruit trees, dead leaves, because the petiole did not come off the layer and still hung on the tree, if not removed will continue to absorb water and increase damage.
Third, the new hair shoots should try to retain even the dense shoots, should also be pulled through the tie, so that a reasonable position, not cut off, with new shoots, new leaves to play photosynthesis efficiency, accumulation of nutrients, to facilitate the tree Recovery of potential.
Fourth, cut or saw the victim's wound wounds, especially large wounds, to be flattened, coated with wax protection, promote healing as soon as possible, trunk and backbone sticks to white, spray, to prevent sunburn, resin disease and anthrax The occurrence of the disease. If the wound is wrapped with a thin film, it should be released at the time of budding so that the bud can be normally smoked.
