How many varieties of poplar are there, and what are the common varieties?

Poplar is a common and familiar nursery stock for everyone. It is tall and majestic, grows rapidly, can windproof and fix sand, and can also absorb exhaust gas, making it a tree species planted for afforestation and protection in many regions. But poplars shed catkins, which seriously affects people's travel and health, so in recent years many areas have been cutting down poplars. Below, let us learn together about the time when poplar catkins drift, the price, and the varieties.

1. What are the common varieties of poplar

1. Black poplar. The bark is dark gray, the buds are long ovate, the flowering period is April to May, and the fruiting period is June. Naturally, it mostly grows on riverbanks, river bends, and coastal sand dunes. Black poplar is cold-resistant, light-loving, not tolerant of saline-alkali soil, and not tolerant of drought. It is distributed in northern China and North Asia and other places.

2. Bigleaf poplar. The bark cracks in flakes and is rough. Its leaf shape is the largest among poplars, and the tip is usually acuminate. It mostly grows in low mountain plains with deep soil layers and abundant rainfall, and usually exists in shrub form.

3. White poplar. This variety of poplar has dense green leaves and naturally spreading branches. It is dioecious, and in spring the inflorescences open before the leaves. The most famous feature of white poplar is that the trunk is very straight.

4. Cathay poplar. It is a common variety in northern China. The bark is grayish green when young and grayish white when old. The petiole is cylindrical. It blooms from March to May and fruits from May to July. Its main producing areas are Liaoning, North China, Northwest China, Sichuan and other provinces in China.

5. Euphrates poplar. It is one of the rare tree species in nature. Its leaves are broad and fragrant, and its wood is slender and soft. It has the characteristics of drought tolerance and waterlogging tolerance. Euphrates poplar can reach an age of 200 years. Because it mostly grows in desert areas, in order to adapt to the arid environment, its leaves are very unique: the leaves on young trees and tender branches are narrow and long like willow, while the leaves on old tree branches are round and smooth like poplar.

6. Italian poplar. It has the characteristics of rapid growth and a straight trunk. Italian poplar can mature in ten years and has very high economic value. It can be planted on both sides of roads and used as a street tree. After ten years, it can be thinned and replanted, combining timber use with windproofing and sand fixation.

2. When do poplar catkins drift

The time when poplar catkins drift differs by region. In the Beijing area, it generally drifts from April 15 to around May 15, lasting one month. Different varieties have different catkin drifting times. The order of drifting is Chinese white poplar, willow and other poplars, such as Simon poplar, Canadian poplar, etc. In fact, catkins are non-toxic, but after these catkins come into contact with some decaying animals and plants, they carry a large amount of bacteria. When the wind blows them everywhere, if people do not wear masks, it is easy to inhale the catkins into the body. In addition, some people are allergic to catkins, so catkins are quite harmful to people. This is also why many areas are cutting down poplars.

3. How much does one poplar cost

The price of willow is related to its variety, height, meter diameter, ground diameter, crown width, etc. At present, silver poplar in Dongfeng County, Liaoyuan City, Jilin Province, with a height of more than 5 m, meter diameter of 6-8 cm, and ground diameter of 8-10 cm, costs 150 yuan/tree; silver poplar in Xiangfang District, Harbin City, Heilongjiang Province, with a meter diameter of more than 20 cm, costs 100 yuan/tree; silver poplar in Junan County, Linyi City, Shandong Province, with a height of more than 5 m, crown width of more than 3 m, ground diameter of more than 20 cm, and meter diameter of more than 20 cm, costs 2000 yuan/tree; black-white poplar in Baiyin District, Baiyin City, Gansu Province, costs 120 yuan/tree.
