During the cold winter months, we often see garden workers painting trees with a white coat of paint. It's not just for the sake of aesthetics, but for more important reasons. So, why whitewash the tree?
First of all, whitening the tree can play a role in heat insulation. In winter, when the temperature plummets, the tree's cellular activity decreases and respiration weakens. At this time, painting the trees with white paint can effectively reflect the sunlight and reduce the absorption of sunlight by the trunk, thereby reducing the temperature of the trunk and slowing down the heat loss of the tree. This protects the trees from low temperatures and ensures that they overwinter safely.
Secondly, whitewashing can play a role in the prevention and control of pests and diseases. During the dormant period of the tree, some germs and pests can hide in the cracks of the trunk. Whitening trees can effectively seal these cracks and prevent the invasion of germs and pests. At the same time, the chemical components in white paint can play a role in sterilization and insecticide, and further protect the health of trees.
In addition, whitewashing can also play a role in preventing sunburn. In summer, strong sunlight hits the trees directly, causing the bark to increase in temperature and water evaporation, causing sunburn. Whitening trees can effectively reflect sunlight and reduce the increase in bark temperature, thereby reducing the incidence of sunburn.
Finally, whitewashing can also play a role in beautifying the environment. The white trunks and green leaves complement each other, making the whole city more tidy and beautiful.
To sum up, whitewashing trees is a scientific and effective method of tree maintenance. It can not only protect trees from low temperatures, pests and diseases, but also beautify the environment and make our city more livable and beautiful. Therefore, we should pay attention to tree maintenance and scientific tree management to make our city better and healthier.
