红松原生于我国东北地区,主要分布在东径126°以东,北纬41°以北的地区,树干高大挺直,木材轻软,不易挠裂,耐腐朽,抗压力强,是优良的建筑、交通、矿山、机械和国防工业用材,也是我国珍贵的用材树种之一。但是红松能不能在我省生长,长期以来还是一个没有解决的问题。1973年以来,我们在地理位置、气候条件与东北比较接近的宽城县都山林场进行了红松引种育苗试验,播种三次,用种2400多斤,育苗3.05亩。除1973年第一次播种的一亩红松因种子处理不当未成苗外,1974年播种的1.08亩和1976年播种的0.97亩,均出苗
Korean pine was born in northeast China, mainly distributed in the east of 126 ° east, latitude 41 ° north of the area, tall and straight trunk, light and soft wood, not easy to scratch, corrosion resistance, strong pressure, is a good building , Transportation, mining, machinery and defense industry timber, but also one of China’s precious timber species. However, pine can grow in our province, for a long time or an unsolved problem. Since 1973, we have conducted seedling trial of Pinus koraiensis in Dushan Forest Farm of Kacheng County, which is close to the northeast in geography and climatic conditions. We sowed seedlings for three times with 2,400 kilos of seeds and 3.05 mu of seedlings. Except for the first seedlings planted in 1973 due to improper treatment of seedless seedlings, 1.08 mu of sown in 1974 and 0.97 mu of sown in 1976 were all emerged
