毛竹也叫楠竹、江南竹、孟宗竹、猫头竹,是我国竹类中分布最广、经济价值最大的一种。产于我国南方广东、安徽、浙江、福建、湖南、江西等省。毛竹竹秆粗,坚韧轻强,竹材富有裂性、弹性和韧性,顺纹抗拉和抗压强度是杉木的三倍,相当于钢材的二分之一至五分之一。在建筑工程中的许多方面,毛竹不仅可以代替木材,而且优于木材。近年来,随着祖国社会主义建设的突飞猛进,毛竹的工程用途愈来愈多。毛竹纤维长是造纸的好原料。毛竹是我国最重要的用材树种之一。毛竹生长快,成林早,从竹笋出土到砍伐利用不过5—6年,比一般速生树种成材期限至少提早15—20年,这对于我国社会主义建设有重大的意义。芮城县一九六五年修建黄河铁桥时用毛竹三万多根,仅打井一项每年要用毛竹三千多根,都是从南方调运来。在毛主席革命路线指引下,该县人民破除迷信、解放思想,以敢想敢干的革命精神,进行南竹北移试验。芮城县引种毛竹试验成功,不仅给毛竹栽培扩大了北移的范围,给我省增添了新的速生树种,而且对省内十五年基本实现木材自给亦具有现实的意义。毛主席教导我们:“推广优良品种。”为加快我省绿化步伐,各地应像芮城县那样,积极引种、培育,优良的新树种。
Bamboo is also called bamboo, southern bamboo, Mengzong bamboo, owl bamboo, bamboo is the most widely distributed in our country, the largest economic value of a. Produced in southern China’s Guangdong, Anhui, Zhejiang, Fujian, Hunan, Jiangxi and other provinces. Bamboo bamboo thick, tough and light, rich in bamboo crack, elasticity and toughness, parallel grain tensile and compressive strength is three times fir, equivalent to one-half to one-fifth of steel. In many aspects of construction, bamboo can not only replace wood but also wood. In recent years, with the rapid development of socialist construction in the motherland, the project uses more and more bamboo. Bamboo fiber length is a good raw material for papermaking. Bamboo is one of the most important timber species in our country. Phyllostachys grow fast, early forest, unearthed from bamboo shoots to use but 5-6 years, than the average fast-growing tree species maturity at least 15-20 years, which is of great significance for China’s socialist construction. Ruicheng County built the Yellow River Iron Bridge in 1965 with more than 30,000 bamboos, and only used more than 3,000 bamboos each year, all from the south. Under the guidance of Chairman Mao’s revolutionary line, the county’s people, breaking superstitions, emancipating their minds and experimenting with the revolutionary spirit of daring to think and doing, conducted a trial in the north. Ruicheng County, the successful introduction of bamboo test, not only to the bamboo cultivation expanded the scope of the north move to our province to add a new species of fast-growing trees, and the basic domestic fifteen years to achieve self-sufficiency timber also has practical significance. Chairman Mao taught us: “Promoting fine varieties.” To speed up the pace of afforestation in our province, we should actively introduce, nurture and fine new tree species throughout Ruicheng County.
