摘要：近几年，我局普遍采用此项技术，樟子松造林的成活率及保存率有了大幅度提高。樟子松容器大苗极适合自然条件恶劣地区进行造林。近几年随着国家防风固沙工程的大规模开展，樟子松容器苗的需求量大幅度增加。不论是防风固沙用苗还是绿化用苗，都需要大苗，培育樟子松容器大苗已经成为大兴安岭地区苗农的主要收入来源，下面就樟子松容器大苗的培育技术加以探讨。

Abstract: in recent years, my bureau adopted this technique, Scotch Pine Afforestation Survival rate and preserving rate has been greatly improved. Container seedlings of Pinus sylvestris is very suitable for areas with adverse natural conditions for afforestation. In recent years along with the national large-scale development of windbreak and sand-fixation engineering, container seedlings of Pinus sylvestris var. demand increases substantially. Whether the windbreak and sand fixation with seedlings or green with seedlings, seedling cultivation of Pinus sylvestris var. need, seedlings in Greater Khingan Range has become Miao Nong ''s main source of income, the Pinus sylvestris container seedlings cultivation technology of.

Key words: Pinus sylvestris container seedling cultivation; technology;

樟子松亦称海拉尔松，为松科松属的常绿乔木树种。樟子松适应性强，耐干旱、耐瘠薄，既是干旱、瘠薄地区造林的先锋树种，又是培育用材林和园林绿化用树的重要树种。 樟子松又叫蒙古赤松，是欧洲赤松的地理变种，系松科松属，高大常绿乔木。樟子松材质轻软，纹理直，强度大，易加工，是建筑、家具、车船、桩木、电杆等良材；立木可割取松脂；树皮含单宁，可提制栲胶；针叶可提制芳香油。樟子松树干通直，冠型优美，四季常青，对二氧化硫等有毒气体具有一定的抵抗能力，而且适应性强，耐严寒、干旱、耐贫瘠，零下40 ℃低温生长正常，抗逆性强。因此，樟子松不但是城镇周边绿化的理想树种而且也是我国北方寒冷山地、沙地及草原上的用材林、防护林的优良树种。

1 容器苗培育中存在的问题

利用容器培育造林苗木是最近几年才推广扩大的，在这几年的栽培管理当中，存在以下几方面问题。……
