泡桐是原产我国的著名速生树种,在一般立地条件下,10年生平均单株材积0.4—0.5立方米。目前大量栽植泡桐的地区,主要集中在华北黄淮平原,而对更适合泡桐生长的广大南方,仍未引起足够的重视。影响南方泡桐发展的原因是多方面的,其中一种说法,认为泡桐是个温带树种(也有称北方树种),不宜在南方发展。应该指出:上述看法不符合泡桐属植物的特性。泡桐不是温带树种,而属于热带、亚热带树种。为此,本文特就泡桐的区系成分问题进行探讨。 Paulownia is a famous Chinese fast-growing tree species, in general site conditions, 10-year-old average single plant volume 0.4-0.5 cubic meters. At present, a large number of areas planted Paulownia, mainly concentrated in North China Huang-Huai Plain, and more suitable for the growth of Paulownia in the vast southern China, has not yet attracted enough attention. There are many reasons that affect the development of S. paulownia. One of the reasons is that P. paulownis is a temperate species (also called northern species) and should not be developed in the south. It should be pointed out: This view does not meet the characteristics of the genus Paulownia. Paulownia is not a temperate species, which belongs to tropical and subtropical species. To this end, this article on the Paulownia floristic composition of the issue.
