Classification of common poplar varieties

1. Black poplar: black poplar is a tree with a height of 30 meters and a broad oval crown. The bark is dark gray and the trenches are cracked when old. Branchlets orbicular, yellowish, glabrous. Buds long ovate, sticky, reddish brown, flower bud apex curved outward. The flowering period is from April to May and the fruiting period is June. Natural growth in the river bank, river bay, less in the coastal sand dunes, often in ribbons or forests. It is cold-resistant, light-loving, saline-alkali intolerant and drought-intolerant. It grows well on alluvial sandy soil and is distributed in North China and North Asia.

2. Populus tomentosa: Populus tomentosa is a deciduous tree with a height of more than 20 meters and a DBH of 0.5 meters. He takes the middle and lower reaches of the Yellow River as the suitable area, and is mostly born in areas with deep soil layer and abundant rainfall in the low mountain plain, usually in the form of shrub. Bark flaky dehiscent, rough. Buds conical, slightly gelatinous, glabrous. Like plenty of rain, rain and heat in the same season. The leaf shape of this species is the largest in the genus Populus, and the apex is usually acuminate and easy to identify.

3. White poplar: White poplar is a general name of the genus Populus of the family Populus. It is native to the Northern Hemisphere. Other plants of the genus Poplar are distributed higher in the north. They are famous for their leaves swaying in the breeze and very straight trunk. Because of the rapid division, more growth into a forest, rare single plant, which is very beneficial to the natural landscape. The bark is gray-green smooth, naturally branched, with dense green leaves, turning bright yellow, dioecious, and the first leaves of the catkin open in spring.

4. Green poplar: Populus tomentosa is a common tree species in northern China. Populus tomentosa is a deciduous tree with a height of up to 30 meters. Crown broadly ovate, bark grayish green when young, smooth, gray-white when old, shallowly longitudinally lobed. Petiole Terete, glabrous. The capsule is ovoid, flowering from March to May and fruiting from May to July. Produced in Liaoning, North China, Northwest China, Sichuan and other provinces, born in valleys, river banks and shady slope foothills.

5. Populus euphratica: Populus euphratica is a deciduous medium-sized natural tree, up to 1.5 meters in diameter, slender and soft wood, broad and fragrant leaves. Resistant to drought and waterlogging, and tenacious in life, it is one of the rare tree species in nature. Populus euphratica can be up to 200 years old, the trunk is straight, 10 to 15 meters high, sparse shrub wood. The leaves are peculiar, because they grow in extremely arid desert areas, in order to adapt to the dry environment, the leaves on the twigs of young trees are as narrow as willow, while the leaves on the old branches of big trees are as round as poplar.
