刺楸(Kolopanax setemlobus koidz)是五加科,刺楸属,落叶乔木。在我国分布较广,长白山林区主要分布在山腹中下部排水良好湿润肥沃的土地上,常与多种阔叶树混生。因为刺楸材质坚实、致密,纹理美观,有光泽,耐磨擦,可供建筑、车辆、造船、乐器和家具等用。树皮和嫩枝可入药,种子含油率38％,是一个经济价值较高、适应性强、生长较快的优良树种。由于刺楸种子育苗难度较大,多年来只采不育,到目前为止其数量越来越少,如不及时采取有效措施加以繁殖和保护,将有绝迹的危险。为此人工培育刺楸就显得更加重要了。现将靖宇县国营苗圃、珲春森林经营局关于刺楸无性繁殖技术经验,综合报告如下。
Catalpa (Kolopanax setemlobus koidz) is a five-family, Congo, deciduous trees. Widely distributed in our country, Changbai Mountain forest areas are mainly distributed in the lower part of the mountains in the drainage of good wet fertile land, often mixed with a variety of broad-leaved trees. Because Katy material is solid, dense, beautiful texture, shiny, abrasion-resistant, for construction, vehicles, shipbuilding, musical instruments and furniture use. Bark and twigs can be used as medicine, seed oil content of 38%, is a high economic value, adaptability, rapid growth of fine tree species. As Catalpa bungei seeds are more difficult to seed, it has only been infertile for many years. So far the number of its population has become less and less. If it does not take effective measures to breed and protect in time, it will be in danger of extinction. Artificial cultivation of Katsura for this purpose is even more important. Now Jingyu County State Nursery, Hunchun forest management on the Catalpa bungei asexual breeding technology experience, a comprehensive report is as follows.
