树干涂白是指树干刷了一层白色的液体，能把10%的阳光反射回去

吸热减少,不会因昼夜温差巨大而冻裂，还有杀菌和防虫的作用

基于三维扫描及大数据，通过雾化喷涂及智能机械臂技术的整合，

提高行道树的护理效率，改善目前行道树护理落后粗放的现状。

The white coating of the trunk means that the trunk is brushed with a layer of white liquid, which can reflect 10% of the sunlight back to reduce heat absorption. It will not freeze and crack due to the large temperature difference between day and night. Through the integration of atomization spraying and intelligent robotic arm technology, the care efficiency of street trees is improved, and the current situation of backward and extensive street tree care is improved.
