bamboo

作者:互联网

Bamboos are a diverse group of evergreen perennial flowering plants in the grass family. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement.

竹子是禾本科多年生常绿开花植物的一个多样化类群。竹子和其他禾本科植物一样,茎的节间区域通常是中空的,横截面上的维管束分散在整个茎中,而不是呈圆柱形排列。

Bamboos include some of the fastest-growing plants in the world. Certain species of bamboo can grow 910 mm (36 in) within a 24-hour period, at a rate of almost 40 mm an hour. Giant bamboos are the largest members of the grass family.

Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo, like wood, is a natural composite material with a high strength-to-weight ratio useful for structures. Bamboo's strength-to-weight ratio is similar to timber, and its strength is generally similar to a strong softwood or hardwood timber.

Most bamboo species are native to warm and moist tropical and to warm temperate climates. However, many species are found in diverse climates, ranging from hot tropical regions to cool mountainous regions and highland cloud forests.

Bamboo forest = 竹林。culm = (竹、芦、草等的)茎,秆。

Unlike all trees, individual bamboo culms emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During this time, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens.

与所有树木不同,竹竿在三到四个月的一个生长季内,以全直径从地面上长出,并长到全高。在这段时间里,每一个新梢垂直生长成一个秆,直到达到成熟高度的大部分时才分枝。然后,分支从节点延伸出来,并出现叶状突起。第二年,每根茎秆的果肉壁慢慢变硬。

Bamboo shoots or bamboo sprouts are the edible shoots of many bamboo species. They are used as vegetables in numerous Asian dishes and broths. They are sold in various processed shapes, and are available in fresh, dried, and canned versions.

竹笋或竹笋是许多竹类的食用笋。它们被用作许多亚洲菜肴和肉汤中的蔬菜。它们以各种加工形状出售,有新鲜的、干燥的和罐装的。玉兰片是由新鲜的冬笋或者春笋,经过加工而制成的干制品,由于它的干制品的外形和色泽都很像玉兰花的花瓣而得名。
