雨树在广州南沙地区的生长表现及应用前景

针对雨树在南沙地区的引种栽植及其6年中生长发育情况表现，对其在南沙的生长适应性进行了比较系统的研究。结果表明：广州因南沙每年出现低温寒潮，雨树在南沙地区的生长是以每年重发新枝的形式进行。每年春季的萌芽发生在前一年未受到伤害的枝条上，以此增加生长量；株形明显比新加坡当地种植的差，甚至成为长不大的苗木，很难体现雨树的“速生”特点，不能形成理想树冠。为此，雨树在广州地区引种、推广和应用，必须慎重。

The Growth Performance and the Potential Application of Albizia saman in Nansha Area, Guangzhou

Based on the simadon of the introduction of Albizia saman in the Nansha area and its performance in recent years, this paper studies the growth of its adaptability in Nansha systematically.The results show that,because the subtropical marine climate influence, Nansha will be appeared every year the low temperature cold wave. The growth of Albizia saman is in the form of growing new branches. Every year spring germinates association president, in the preceding year has not received the injury on the branch, increases the growth quantity by this.The shape of the plants significantly worse than the new ones planted in Singapore, or even these plants never grow up after many years. It is difficult to reflect the rapid growth character of Albizia saman, and can not form an ideal crown.
