永定县珍稀树种造林试验研究

通过对小叶桢楠（Phoebe microphylla）、柚木（Tectona grandis）、降香黄檀（Dalbergia odorifera）、沉香（Aquilaria agallocha）和檀香（Santalum album）5种珍稀保护树种进行造林试验,调查栽植1年后各树种的生长情况和成活率。结果表明：小叶桢楠、柚木的树高生长量和成活率较高,且对立地条件要求不高,可在永定县进行推广栽植;沉香和降香黄檀的树高生长量和成活率较低,对立地条件要求较高,畏寒怕冻,应控制其栽植规模;檀香在造林试验中未见成活,不适于在永定县推广栽植。

Afforestation Experiments of Rare Species in Yongding County

Experiments of five species of rare and protected trees （Phoebe microphylla ,Tectona grandis ,Dalbergia odorifera ,Aquilaria agallocha ＆amp; Santalum album） were conducted to investigate the growth ＆amp; survival rate of each species after one year .Result shows that ：Phoebe microphylla ＆amp; Tectona grandis ,which have less demanding on site conditions ,have higher height grow th ＆amp; survival rate ,and should be popularized in Yonding County .A qui-laria agallocha ＆amp; Dalbergiaodorifera ,which have more demanding on site conditions ,have lower height growth ＆amp;survival rate ,afraid of cold chills ,should be controlled the size of their planting ;Santalum album are not survived in the afforestation experiments and are not suitable to promote in Yongding County .
