The cherry blossoms in Alishan suffer from heavenly dog nest disease.

"without proper treatment, the Alishan cherry blossoms may disappear in a few years." Liu Dongqi, an assistant professor in the horticulture department of Chung Hsing University, said that Yoshino Sakura in Alishan has contracted Sakura's nest disease, which cannot be cured, but it can still be saved. As long as we try to strengthen the root system of cherry blossoms, Yoshino Sakura can bloom again.

According to Taiwan media reports, Alishan cherry blossoms attract a large number of people to enjoy the cherry blossoms every year, among which Yoshimi Yoshino Sakura is even named the "king of cherry blossoms", and the beautiful cherry posture makes many tourists linger.

Nian Yoshino Sakura gradually died of Tian Dou nest disease.

However, the Yoshino Sakura in Alishan has withered in recent years, and the Forestry Bureau has asked experts to prevent and cure it. Every year, the Forestry Bureau has spent millions of yuan on rescue, but the situation has not improved. The Forestry Bureau is going to plant an additional 1,000 Yoshino Sakura trees to remedy it.

Liu Dongqi, an assistant professor in the horticulture department of Chung Hsing University, was licensed as a "tree doctor" in Japan. He went to Alishan many times to enjoy cherry trees and found that the flowers were getting worse and worse. Further research found that Yoshino Sakura in Alishan, like those in Japan, is infected with Tiangou nest disease. Because Yoshino Sakura is a single tree species and propagates by cutting, the disease will be passed from generation to generation.

The Forestry Bureau looked for experts to go up the mountain to treat the disease, and removed the trunk where Yoshino Sakura was infected with germs, burned it with fire and covered it with sawdust. Liu Dongqi said that this method treats the symptoms but not the root causes, and the germs are still in the cherry trees and have not been used abroad for a long time.

He said that celestial dog nest disease is not a terminal disease. At present, most of the root growth of Yoshino cherry in Alishan has been damaged, including laying gravel under grass bricks to block root respiration, and tourists watching cherry trees too close to cheap treads, causing the soil to harden. As long as you try to strengthen the root system of cherry blossoms, you can make Yoshino cherry blossoms blossom again.

His method is to insert two bamboo tubes about one meter deep into the ground in the root growth direction of the sick cherry tree, hollow the bamboo tube, put organic fertilizer, cover it with a fine net, and let the water flow down naturally, so that the roots can reabsorb nutrients and water, and the whole plant will come back to life.

Xie Shangda, deputy director of the Chiayi Forest Management Office of the Forestry Bureau, said that Liu Dongqi's method will first find a site to test, and it will be carried out throughout the region with good results.
