杜松(Juniperus rigida Sieb.etZucc.)属柏科刺柏属,又名刚桧、崩松、棒松,新疆群众称刺柏.杜松为亚乔木,高约10米,四季常青,树形美观,树冠塔形或圆柱形,小枝下垂,叶条形.它喜光,耐干早、寒冷和瘠薄,生长较快,木材坚硬,纹理致密,耐腐性强,可供建筑、制作工艺品和家具用,常作庭院观赏树,也是荒山造林的先锋树种.杜松在国内主要分布于东北、内蒙、山西、河北等省,国外在苏联也有分布.为了丰富新疆城市绿化树种,我们从内蒙引进杜松种子,于1979年在本所苗圃和阜康林场三宫苗圃育苗.在本所育出的苗1981年定植,1983年秋测定,5年生平均树高1.04米(当年高生长44厘米),冠幅33厘米,地径1.93厘米.现将杜松的育苗技术介绍于下:
Juniperus rigida Sieb.etZucc. Belongs to the genus Cypress, also known as just cypress, ape, pine, Xinjiang people said Juniper. Juniper tree is about 10 meters high, evergreen, tree Its shape is exquisite, the crown is tower or cylindrical, the branch is drooping, the leaf strip shape.It likes light, dries early, cold and barren, grows fast, the wood is hard, the texture is compact, the decay resistance is strong, Furniture, ornamental trees often used for the courtyard, but also the pioneers of barren hills afforestation Juniper is mainly distributed in the Northeast China, Inner Mongolia, Shanxi, Hebei and other provinces, foreign countries are also distributed in the Soviet Union.In order to enrich the urban greening tree species in Xinjiang, we introduced from Inner Mongolia Juniper seeds were raised in Sannong Nursery of Nursery and Fukang Forestry Center in 1979. The nursery plants bred in this year were planted in 1981 and measured in the autumn of 1983 with an average tree height of 1.04 meters (44 centimeters high in the current year) Crown 33 cm, 1.93 cm in diameter now Juniper seedling technology introduced in the next:
