During the growing season, they are short-cut and cut-and-pruned, artificially causing wounds. In the case of medium-temperature and high-humidity environment, the wounds are prone to gelation. By adjusting the trimming period, the growing period is trimmed to hibernation pruning. Although winter pruning also has wounds, due to lower temperatures and dry air, there is little leakage of glue.
