在众多植物中,竹子的生长速度是最快的。竹子是多年生的常绿植物,它的地下茎(俗称竹鞭)既能贮藏和输送养分,又有很强的繁殖能力。它是横着长的,和地上的竹子一样有节,节上长着许多根须和芽。这些茎节上的芽,在出土之前已储存了各种生长必需的养分。到了春天天气转暖时,就会向上升出地面,外面包着笋壳, Among many plants, bamboo grows fastest. Bamboo is a perennial evergreen plant, its underground stem (commonly known as bamboo whip) can both store and transport nutrients, but also a strong breeding ability. It is long and horizontal, like the bamboo on the earth, with many roots and buds. Buds on these stems have stored a variety of nutrients necessary for growth before they were unearthed. When the weather gets warmer in spring, it will rise out of the ground and cover the shell with bamboo shoots.
