First of all, the tree species are different.
1, hazelnut tree
Hazelnut tree, also known as hazelnut, is one of the four largest dried fruits in the world (walnuts, almonds, hazelnuts and cashews). Belongs to betulaceae and Corylus.
2. Cyclobalanopsis glabra
Chinese name Quercus, alias Quercus, Quercus, Cyclobalanopsis, Golden Rooster, Poirot, etc. It belongs to FAGACEAE and Quercus.
Second, the morphological characteristics are different.
1, hazelnut tree
Height1-7m, gray bark, dark gray branches, hairless, yellowish brown branchlets, densely pubescent, sparsely villous, without or with spiny glands. The outline of the leaf is rectangular or broadly obovate, with a length of 4-13cm and a width of 2.5-10cm. The top of the leaf is concave or truncated, with a triangular tip in the center and a heart-shaped base, sometimes with unequal sides. The edge has irregular double serrations, and the upper part is shallow and hairless. The lower part is sparsely pubescent when young, and then only sparsely pubescent along the veins.
2. Cyclobalanopsis glabra
Up to 25 meters high, the bark is dark grayish brown and deep in the longitudinal direction. Branchlets stout, grooved, densely covered with gray-yellow stellate villi. Buds are broadly ovate and densely yellow-brown tomentose. Leaf blade obovate or long obovate, length 10-30cm, width 6-20cm. The blade tip is short and blunt, the leaf surface is dark green, the base is auriculate, the leaf margin is wavy or coarsely serrated, it is hairy when it is young, and it gradually falls off, and the back of the leaf is densely covered with grayish brown stellate fluff.
Third, the growth distribution is different.
1, hazelnut tree
Born in shady thickets in mountainous areas at an altitude of 200- 1000m, it has strong cold tolerance and likes humid climate. It likes light, and sufficient light can promote its growth, development and fruit.
Distributed in China (Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, Anhui, etc.). , cultivated in Shandong and Jiangsu), Turkey, Italy, Spain, the United States, North Korea, Japan, Russia, Eastern Siberia and the Far East, and eastern Mongolia.
2. Cyclobalanopsis glabra
It is a strong positive tree species, which is light-loving, drought-tolerant and barren-tolerant. It is suitable to grow in sandy loam with good drainage, but not in calcareous soil, saline-alkali land and low humidity and waterlogging area. Most mountainous areas in northern China are located on sunny slopes below 500 meters above sea level. Deep-rooted tree species have strong germination and tillering ability, long life, strong wind resistance, fire resistance and smoke resistance, but their growth rate is slow.
Mainly produced in northern China, Henan, Hebei, Shandong, Yunnan, Shanxi and other provinces are more common, Liaoning, Shaanxi, Hunan, Sichuan and other provinces are also distributed; The oak forest distributed in Wei Zi, Xiangcheng County is one of the best preserved oak forests at present. Korea and Japan are also distributed.
