Willow is a kind of plant with ecological amplitude, which has wide adaptability to the environment. Like light, wet and cold, it is a medium-sized wet tree species. However, some species are also more drought-tolerant and salt-tolerant, can grow in places with poor ecological conditions, and grow better in plain areas with excellent site conditions.
The average life span is 20 ~ 30 years, and a few varieties can reach 100 years or more. The annual growth period is long, with early germination and late defoliation, and individual tree species in the south are evergreen trees.
Extended data
Salicaceae plants are well known and loved by people of all ethnic groups because of their strong ecological adaptability, fast growth, easy reproduction, short rotation period, easy management and wide use.
At present, the focus of international utilization of this tree has shifted from producing wood to transforming nature and beautifying the environment. Among them, Salix has been widely studied in the world because of its high biomass per unit area, unique absorption of greenhouse gases and high development value.
In Inner Mongolia, Salicaceae plants, as mountain forest vegetation, swamp vegetation, shrub vegetation and sand vegetation, play an important role in forest belt and forest grassland belt. Among them, most species of Salix are the main components of riparian shrubs in forest and grassland areas, and a large area of riparian species has been formed in the northern Daxinganling Mountains in this area.
