本主主要从选择圃地、做床、播种、田间管理、防寒等技术环节入手总结樟子松沙地育苗技术。樟子松为欧洲赤松的地理变种,在我国自然分布于内蒙西部及黑龙江大兴安岭海拔300-900米地区,西起莫尔道嘎、金河、根河到呼玛一线,以北多成片状纯林,以南多与落叶松、白桦混生。呼盟达来湖和海拉尔一线以东沙地有樟子松林,程岛状分布,小兴安岭也有分布。该树种适应性强,喜光、耐寒、抗旱,幼苗不耐荫。深根性,对土壤要求不严,但在沼泽地,积水地生长不良。喜酸性土壤。樟子松人工林在“三北”地区均有分布,尤其在沙区长势良好。
The main start from the choice of nursery, bed, sowing, field management, cold and other technical aspects to sum up Pinus sylvatica Sand seedling technology. Pinus sylvestris var.mongolica is a geographical variation in China. It is naturally distributed in western Inner Mongolia and Daxinganling of Heilongjiang Province in China. The area is 300-900 meters above sea level in the west of Mozambique. Pure forest, south of Larix, birch mixed. Huyuntanda Lake and Hailar to the east of the sand have Pinus sylvestris, Cheng Island-like distribution, there are also distributed Xiaoxinganling. The tree adaptability, hi light, cold, drought, seedling shade. Deep-rooted, lax requirements of the soil, but in wetlands, stagnant water. Hi acidic soil. Pinus sylvestris plantations in the “Three North ” area are distributed, especially in the sand growing good.
