刺楸为落时乔木,在我国分布广泛,少有病虫害及气象灾害,干形通直园满,树形美观,纹理优美,刨削后有光泽,干燥后不甚收缩,抗腐力强,用途广泛,特别是高档家具的良材。既是珍贵的用材树种,又是美化环境的观赏树种。由于其根株有萌蘖性,也是良好的水土保持树种。用它和红松、红皮云杉等针叶树混交,有利于针叶树的速生丰产,是我省重点保护的树种之一。但由于过去遭到严重的滥伐,成片的径级较大的已属罕见,散生木也不多见。如不及时采取有效措施加以繁殖,则将来恐有绝迹的危险。所以研究刺楸的育苗造林技术,是当前一项重要任务。现将有关研究刺楸的技术资料综述如下: Catalpa bungei is the arbor tree when it falls, widely distributed in our country, with few pests and diseases, meteorological disasters, dry and straight garden, beautiful tree, beautiful texture, glossy after gouging, less shrinkage after drying, Wide range of uses, especially high-end furniture, good material. Both precious timber species, but also beautify the environment ornamental species. Because of its rooting sprouting, is also a good soil and water conservation tree species. Use it and pine, red spruce and other conifer mixed, is conducive to coniferous fast-growing, is one of the province’s key species of protection. However, due to the serious deforestation suffered in the past, it is rare for large-scale films to be formed, and loose wood is rare. If not promptly take effective measures to breed, then there may be no danger of extinction. Therefore, the study of Catalpa bungei nursery afforestation technology, is an important task. The relevant information on the study of Katsura now summarized as follows:
