What kind of tree is Cyclobalanopsis?

Cyclobalanopsis Tree Name: Cyclobalanopsis Quercus

Scientific name: Cyclobalanopsis glauca. ) oster. ;

Other names: mahogany, Castanopsis fargesii, flowering treetops, paulownia and Quercus variabilis.

Family: Fagaceae.

Genus: Quercus

Distribution of origin

It is a subtropical tree species and one of the most widely distributed tree species in China. South Korea, Japan and India are also distributed. Deciduous, evergreen and broad-leaved mixed forests in the north and south subtropics of the Yangtze River (major cities: Nanjing, Yangzhou, Zhenjiang, Nantong, Changzhou, Wuxi, Suzhou, Hefei, Wuhu, Anqing, Huainan, Xiangfan and Shiyan) and evergreen and deciduous broad-leaved forests in the middle subtropics (major cities: Wuhan, Shashi, Huangshi, Yichang, Nanchang, Jingdezhen, Jiujiang and Ji 'an)

morphological character

Evergreen trees, yellow-green May flowers, unisexual flowers, male inflorescences, slender drooping. Nuts are oval or ovoid, born in cup-shaped shells and mature in 10.

Growth habit

The sensitivity to climatic conditions is due to the change of the ratio of chlorophyll and anthocyanin contained in leaves. After a long drought, just before the rain, chlorophyll synthesis was blocked in hot and muggy days, which made anthocyanins dominant in leaves and the leaves gradually turned red. People in some places know from their usual observation of the green bar trees that when the leaves turn red, it will rain heavily in this area in a day or two. After the rain, the leaves are dark green. According to this information, farmers predict the weather and arrange farm work. Neutral and fond of light, slightly resistant to lateral shade when young. I like to grow on slightly alkaline or neutral limestone soil and grow well on acidic soil. Roots are deep and main roots, drought-tolerant, and can grow in rocky mountainous areas. Strong germination, germination can be used for renewal.

Evergreen trees of FAGACEAE, up to 20 meters high. Leaves alternate, leathery at the top of branches, ovoid, obovate-elliptic, short and sharp at the top, wide wedge-shaped at the base of leaves, and teeth above the middle of leaves. Female flowers have several axillary branches and leaves. The shell bucket is bowl-shaped with a diameter of about1cm; Nut ellipsoid, length 1.2- 1.7 cm, diameter 1 cm.

Except Yunnan and other provinces, it is widely distributed in the south of the Yangtze River. Rich in resources.

Wood is hard and corrosion-resistant, and is generally used to make railway sleepers, as well as furniture and utensils. [Edit this paragraph] Version 2 Qinggang Tree, also known as Cyclobalanopsis glauca, is called "Meteorological Tree" because its leaves will change with the weather.

Qinggang Tree is a subtropical tree species, which is common in southern China. It is sensitive to climatic conditions, because the ratio of chlorophyll and anthocyanin in leaves has changed. After a long drought, just before the rain, chlorophyll synthesis was blocked in hot and muggy days, which made anthocyanins dominant in leaves and the leaves gradually turned red.

Farmers in some places have learned from their usual observation of the green bar trees that when the leaves turn red, there will be heavy rain in this area for a day or two, and after the rain clears, the leaves turn dark green. According to this information, farmers predict the weather and arrange farm work.

There is a "meteorological tree" that can "predict" the drought and flood situation in Anhui Province and the county. This tree is more than 10 meters high. Its trunk can only be surrounded by three children holding hands, and its crown covers more than 100 square meters of ground. It is said that this tree has been growing for more than 400 years. After years of observation, it has been found that according to the time of germination and the density of leaves, we can know whether it was a drought or a flood. For example, trees germinate in front of Grain Rain, and the buds are leafy, so there is more rain this year; Sprouting on time, sparse and dense leaves, the weather is generally good this year; Grain Rain will germinate later, with few and thin leaves, so it will be dry this year. 1934, this tree sprouted after Grain Rain, and there was a severe drought that year. 1954 This tree germinates early and its leaves are flourishing. That year, there was a flood in the local area. Some locals regard this tree as a "sacred tree". Why can this tree predict the drought and flood of that year? Although after investigation, we haven't found a really convincing reason.
