Why should trees be painted with lime?

1, sterilize, prevent bacterial infection and accelerate wound healing. 2, insecticidal, insect-proof. * * * Overwintering eggs and moths in bark. Pests generally prefer black and dirty places to white and clean places. 3. Prevent freezing injury and sunburn, and avoid freezing injury in early spring. It is convenient to walk at night. When trees are painted white, they will reflect light. Pedestrians can see the road more clearly at night.

In winter, the temperature is very low at night, and it is exposed to sunlight during the day. The temperature rises and the trunk is easy to crack. After applying limewater, 40%~70% of sunlight can be reflected, and the temperature of the trunk is not much different between day and night, so it is not easy to crack. It can also beautify and give people a very neat feeling.

Trees such as Sophora japonica, Ulmus pumila, Lagerstroemia indica, Albizia Albizia, Populus euphratica, Lu 'an, Willow, Cherry Blossom, Michelia, etc. can be painted mainly, while other trees with less pests and diseases such as Metasequoia glyptostroboides, Ginkgo biloba and Ailanthus altissima can be painted without pests and diseases.

After wearing a white dress made of limewater, the trunk can reflect 10% sunlight back. In this way, the heat absorption is reduced, the trunk will not be frozen and cracked due to the huge temperature difference between day and night, and it also has the function of sterilization and insect prevention. Unique scenery in the city.
