意味

ポプラ（楊樹）

One of the most common trees in northern China, planted extensively along roads, in parks, and on farmland windbreaks. Poplars are fast-growing and used for timber, paper pulp, and environmental protection. In spring, female poplar trees release abundant white cotton-like seed fluff (杨絮 — poplar catkins/fluff) that floats through the air, a familiar and often complained-about feature of Beijing springs.

例文
