This invention provides a multifunctional, breathable tree grate, comprising a first grate body and a second grate body, which are spliced ​​together. A circular through-hole is located at the center of the spliced ​​first and second grate bodies. Multiple ventilation holes are formed on both the first and second grate bodies, evenly distributed circumferentially along the circular through-hole. A rotatable support mechanism is provided on the top surface of both the first and second grate bodies. These two support mechanisms work together to support the tree trunk, keeping it vertical. The support mechanism has a self-locking function. In this invention, the support components can support the sidewalls of the tree trunk, thus preventing it from tipping over. Workers can accurately and promptly locate a fallen tree trunk by combining positioning information and the trunk's tilting status, then straighten it back to an upright position, ensuring the tree can grow normally.
