樟子松(Pinus sylvestris var.mon-gorica)主要分布在我国大兴安岭和内蒙与黑龙江交界的呼伦贝尔草原,为常绿高大乔木,树高可达20余米,干形通直,自然整枝良好,耐寒、耐干旱、耐瘠薄,能够在平均气温0 ℃以下、绝对最低气温-40—-50℃、有永冻层的地区生长,且生长比较迅速.樟子松于1966年引入新疆,生长良好,1978年结实,种子千粒重为7.2克.我们于1981年开始研究樟子松的育苗问题.研究表明,樟子松于平原地区育苗效果最好.设在乌鲁木齐市六道湾林业试验站的试验地,五年共生产出三年生出圃苗22万株,供应了全疆各地.现将樟子松平原地区育苗技术简介于下.
Pinus sylvestris var. Mon-gorica is mainly distributed in the Hulunbuir steppe of Daxinganling, Inner Mongolia and Heilongjiang at the junction of Inner Mongolia and Heilongjiang. It is a tall evergreen tree with a height of more than 20 meters. , Tolerant to drought and barren, it can grow in areas with permafrost with an average minimum temperature below 0 ℃ and absolute minimum temperature of -40 ℃ to 50 ℃, and its growth is relatively rapid .Smongolsia was introduced into Xinjiang in 1966 and grows well, In 1978, seed thousand grain weight of 7.2 grams .We started in 1981 study Pinus sylvestris nursery problems .Studies show that Pinus sylvestris seedlings in the plains of the best breeding effect .In UrumqiLiudaowan forestry experimental station test site, Five years produced a total of 220,000 nursery stock three years gave birth to all parts of Xinjiang. Now Pinus sylvestris plains area breeding technology in the next.
