杉木是我国南方主要用材树种,生长快,干形直,材质好,用途广。据南方九个省区不完全统计,共有杉木林5630万亩,木材蓄积量23150万立方米。建国以来,特别是无产阶级文化大革命以来,我国南方各省区都在积极营造杉木速生丰产林,高产典型不断涌现,如湖南会同11亩6年生杉木林每亩蓄积量4.3立方米,贵州锦屏5亩8年生杉木林,每亩蓄积量13立方米;同时,大面积用材林基地,也在逐步形成,如湖南株石杉木林基地就达40万亩,湖北广济杉木林基地也达12万亩,集中连片,而且到处出现“种杉如种田,管杉如管棉”的大好局面。我省发展杉木历史虽不长,但由于各级党委重视,广大干群积极努力,全省现有杉木林已经超过25万亩。苏南地区千亩、万亩以上杉木林基地正在不断出现,苏北赣榆和沿海阜宁,试种杉木,也获成功,长势喜人,为加速实现我省地方用材自给,有了良好的开端。
Cunninghamia lanceolata is the main timber species in southern China, growing fast, dry straight, good material, wide use. According to incomplete statistics of nine southern provinces and autonomous regions, a total of 56.3 million Chinese fir forest, 231.5 million cubic meters of timber stock. Since the founding of the People’s Republic of China, especially since the Great Proletarian Cultural Revolution, all the southern provinces and autonomous regions in our country are actively creating fast-growing Chinese fir plantations. High-yielding typical examples are constantly emerging. For example, 11 cubic meters of 6-year- Mu 8-year-old fir forest, volume per acre 13 cubic meters; the same time, a large area with timber base, is also gradually formed, such as Hunan Zhu Shi fir forest base reached 40 million mu, Hubei Guangji Chinese fir forest base also reached 12 million mu , Concentrated contiguous, and everywhere, “such as planting fir, fir tube tube cotton” a good situation. Although the history of the development of fir in our province is not long, due to the importance attached by party committees at all levels and the active efforts of the majority of cadres, the existing cedar forest in the province has exceeded 250,000 mu. In the south of Jiangsu Province, more than ten thousand mu of Chinese fir forest base is emerging constantly. In Gansu of northern Jiangsu and Funing along the coast, Chinese fir plantation has also been succeeded and developed. In order to speed up the self-supply of local timber in our province, it has a good beginning .
