After entering the winter and the spring of the next year, the temperature difference between day and night is large. By whitening, you can reflect the sun and ultraviolet rays in the daytime, reduce the temperature difference between the day and night of the trunk and avoid freezing damage. White-painted trees tend to delay the germination and flowering of trees because of the slower temperature accumulation at the base of the trunk, which can avoid frost damage caused by “cold springâ€. 6, to prevent sunburn. After the trunk is painted white, the daytime sunlight and ultraviolet rays can be reflected out, which can effectively reduce the occurrence of sunburn hazards.
