油松系常绿针叶大乔木,是我国华北、西北、和东北南部地区营造用材林和水土保持林的一个重要树种。耐干旱瘠薄,在微酸性土、中性土及钙质黄土上均能生长。幼苗生长较慢,4—5年后渐快,10—20年间高生长最快,30—50年间直径生长最快。幼小喜阴,长大喜光。深根性,抗风力强。木材坚韧,抗压力大,耐腐性强,可供建筑、农具、矿柱、枕木、电杆等用,大树能采割松脂,枝条是很好的烧柴。在我省的乐都、互助、化隆、尖扎等县有天然分布。西宁市湟水林场1964年营造的人工林,至1975年平均树高3米。近年我省己将油松列为浅山地区主要造林树种之一。为了尽快发展这一树种,75年和76年我们在大通县半沟大队(浅山)旱地和水地共育
Pinus tabulaeformis is a evergreen coniferous tree, which is one of the important tree species for timber plantation and water and soil conservation in North China, Northwest China and South East China. Arid barren infertile, in slightly acidic soil, neutral soil and calcareous loess can grow. Seedlings grow slowly, 4-5 years later, the fastest growth in 10-20 years, 30-50 years, the fastest diameter growth. Young hi yin, grow up hi light. Deep-rooted, strong wind resistance. Timber tough, anti-stress, corrosion resistance, for construction, tools, pillars, sleepers, poles and so on, the tree can cut loose resin, branches are good firewood. In our province, Lidu, mutual aid, Hualong, Jianzha and other counties have a natural distribution. Xining Lushui Forest Farm in 1964 to create a plantation, to 1975 the average tree height of 3 meters. In recent years, our province has Pinus tabulaeformis as one of the main afforestation species in shallow mountains. In order to develop this species as soon as possible, in 75 and 76 years we were in Datang County half ditch brigade (shallow mountain) dry land and water
