I like light, but I don't like cute. Cold-resistant, no frostbite at MINUS 40 degrees. The climate is drought-tolerant, but not hot and humid, and the southern cultivation is prone to pests and diseases, and the trunk is often shrub-like. Weak alkaline soil, soil with salt content below 0.4%, grows poorly in cohesive soil. Deep roots, developed roots, strong soil-fixing ability and strong tillering ability. Strong wind resistance and pest resistance. The service life is over 90 years. Poplar's temperament is civilian, but it is the richest. She can be used as firewood, furniture, purlin and farm tools. Like the yellow land where she grew up, it is unpretentious. In some people's eyes, she will almost forget her existence. But for the barren yellow land, she is a brave person. Throughout the year, she stayed and decorated, which reduced the poverty and loneliness of the yellow land and increased the vividness and beauty, because her roots have been integrated with the yellow land. Poplar did not expect to transplant and migrate, even if her fallen branches and leaves were corroded by soil, it would add some nutrients and vitality to this yellow land. Under the thick loess, the immortal life of poplar is surging, and the yellow land is crisp and green.
Another name for poplar bark (Tang herbal medicine): poplar bark (Fang).
