红杉是普遍分布于四川省高山林区的一种速生树种,材质坚实耐久,强度较大,是建筑、枕木、矿柱、车辆、造船等的优良用材。过去,由于对红杉的性能缺乏了解,一直认为不能采用水运流送,因而未能充分地进行采伐利用,在一定程度上浪费了国家的森林资源。为了更好地贯彻合理采伐、合理利用,大力发展木材生产,在批林整风、批林批孔运动的推动下,开展了群众性的科学实验活动。从1973年3月开始,在川西米亚罗、丹巴一一四场党岭,马尔康种检站等地进行了红杉原木漂浮试验,通过多次测定,基本摸清了红杉原木漂浮的规律,解除了红杉不能水运的禁令。
Sequoia is a kind of fast-growing tree widely distributed in the mountainous area of Sichuan Province. It is solid, durable and strong in strength. It is an excellent material for construction, sleepers, pillar, vehicle and shipbuilding. In the past, due to a lack of understanding of the properties of Sequoia, it has been considered that water transport can not be used and therefore inadequate harvesting and utilization have been wasted and to a certain extent, the country’s forest resources have been wasted. In order to better carry out reasonable harvesting, make rational use of and vigorously develop timber production, the mass scientific experiment activities have been carried out under the impetus of the campaign of rectifying forests and criticizing forests and holes. From March 1973 onwards, in the western Sichuan Miyaluo, Danba one hundred and four Dangling, Malcolm inspection station and other places of the redwood wood floating test, through several determinations, basically find out Sequoia logs floating Law, the lifting of Sequoia can not water ban.
