"10 cm, 6 cm, 2 cm, five years of tracking, the hole narrowed and shortened year by year, I really didn't expect our restoration work to allow the tree to achieve self-healing wounds. This is the deputy head of the landscaping team of Qingshan District, Wuhan City, Jiang Nian, who saw the Dafa Tong restored in 2019, and now the trunk hole has almost completely healed, and he can't help but sigh with heartfelt emotion.
Jiang Nian showed the reporter a number of pictures of big trees tracking and observing, one of which was planted in front of the bus station of Jiansi Road and Bajia, and four photos taken in different years recorded the process of its self-growth after the restoration of the tree hole skin. "After five years of growth, the wound is now very small, and now in order to allow the wound to completely heal itself, we re-turned the tree tray in the spring, applied nitrogen fertilizer and organic fertilizer, and scraped the skin around the wound with a knife again, using the spring germination period to promote the inward growth of the wound with external force. When Jiang Nian followed the Dafa Tong in April 2024, he once again prescribed a "beauty plan" for this Dafa Tong.
According to reports, most of the trees on the street in Qingshan District are more than 50 years old, and due to urban construction and rainwater erosion, the trunk of Dafa tung trees has been damaged and rotted hollow. In addition to the control of borer-boring pests, it is also necessary to carry out fine repairs to these tree holes. From late autumn to April of the following year, the tree grows slowly after entering the dormant period, which is the best time to repair the tree hole.
Jiang Nian believes that the restoration of large trees is like modern people doing "medical beauty", shallow medical beauty is only a temporary beauty, and the most effective "medical beauty" is to promote the regeneration of inner cells, so that plants can rejuvenate their vitality. The restoration of big trees is by no means an overnight effort, it takes a long time, as a gardener should continue to use scientific and effective management methods, so that they can rejuvenate themselves and become the "witnesses" of the city's historical changes.
