Arborvitae trees are produced in southern Inner Mongolia, Jilin, Liaoning, Hebei, Shanxi, Shandong, Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi, Henan, Shaanxi, Gansu, Sichuan, Yunnan, Guizhou, Hubei, and Hunan , northern Guangdong and northern Guangxi and other provinces and regions. It is cultivated in Deqing, Dazi and other places in Tibet.
The vertical distribution reaches 250 meters above sea level in Jilin, 1000-1200 meters in Hebei, Shandong, Shanxi and other places, 1500 meters in Henan, Shaanxi and other places, and 3300 meters in central and northwest Yunnan. There are natural forests in the valleys of Xinglong in Hebei, the Taihang Mountains in Shanxi, the Wei River Basin north of the Qinling Mountains in Shaanxi, and the Lancang River Basin in Yunnan. Afforestation is mostly used in carboniferous mountains, sunny slopes and plains north of the Huaihe River and North China.
It is also distributed in North Korea.
Extended information
Arborvitae prefers light, is slightly shade-tolerant when young, has strong adaptability, and is not strict on soil requirements. It can thrive in acidic, neutral, calcareous and lightly saline-alkali soils. All can grow. It is resistant to drought and barrenness, has strong germination ability, medium cold tolerance, strong sunlight resistance, high temperature resistance, and shallow rooting. It is only distributed below an altitude of 900m in Shandong, and grows well below an altitude of 400m. Wind resistance is weak.
Arborvitae is both cultivated and wild. It likes to grow in moist, fertile and well-drained calcareous soil. It is cold-resistant, drought-resistant, and salt-alkali resistant. It can grow on flat land or cliffs. On dry and ridge-poor mountains, it grows slowly and the plants are thin and weak.
It has shallow roots, but well-developed lateral roots, strong germination, resistance to pruning, long life, resistance to smoke, dust, sulfur dioxide, hydrogen chloride and other harmful gases. It is widely distributed and is one of the most commonly used ornamental trees in China.
Arborvitae can adapt to cold climates. However, in some years in this area (Yanshan County, Yunnan Province), seedlings have been drained to a certain extent. They have strong drought resistance, loose soil requirements, strong salt-alkali resistance, and can adapt to growth even with a salt content of about 0.2%. .
