竹类植物属禾本科的竹亚科,常绿乔木或灌木。芦竹属禾本科的禾亚科,多年生草本。竹类植物主要生长在热带、亚热带地区,也有少数属、种生长在温带甚至亚寒带地方。生长快、产量高、用途广、收益大。一次造林成林,即可连年采伐利用。一般竹子造林五——十年后,就可年年砍伐利用。一棵粗十几厘米、高二十几米的毛竹,从出笋到成竹只要两个月左右的时间,经过四到六年的加固生长就可砍伐,如作为纤维造纸原料,当年就能利用。生长好的竹林,每亩年产竹材三、四千斤,即约为1.5—2.0立方米竹材实积,超过一般速生林生长量的1—2倍。竹子的收缩最小,割裂性、弹性和韧性 Bamboo plants are grassy bamboo subfamily, evergreen trees or shrubs. Arundo donax Gramineae subfamily, perennial herb. Bamboo plants mainly grow in the tropics, subtropics, there are a few genera, species grow in temperate or even subtropical zone. Fast growth, high yield, wide use, big income. Once afforestation into forest, logging can be used year after year. General bamboo afforestation five - ten years later, you can cut annual use. A rough ten centimeters, twenty meters high bamboo, from bamboo shoots into bamboo as long as two months or so, after four to six years of solidification growth can be cut, as raw materials for fiber paper, then you can use . Growth of good bamboo, bamboo yield per mu, three or four kilograms, that is about 1.5-2.0 cubic meters of bamboo plot, more than 1-2 times the growth rate of general fast-growing forest. Bamboo contraction of the smallest, fragmentation, flexibility and toughness
