泡桐在浙江境内天然分布广泛,是优良的速生树种。近几年来泡桐已逐渐成为主要造林树种而广为种植。但各地实践说明,泡桐定栽后的生长很不平衡。这固然与立地条件选择、造林质量及抚育管理水平有密切关系,但物种混杂、没有选用优良物种亦是主要原因之一。为提供泡桐种植中物种选择的依据,我们从1978年起对泡桐各主要物种在本地区的生长情况进行了研究,现将试验结果分析讨论如下。
Paulownia in Zhejiang Province is widely distributed in nature, is an excellent fast-growing tree species. Paulownia in recent years has gradually become the main afforestation species and widely planted. However, practice shows that around the world, Paulownia planted growth is very uneven. Although this is closely related to site selection, afforestation quality and tending and management level, it is one of the main reasons why species are mixed and no good species is selected. In order to provide the basis for species selection in Paulownia planting, we have studied the growth of each Paulownia species in our region since 1978. The results of the analysis are discussed below.
