| 摘 要： | 通过引进实生苗开展栽植试验,并观测和分析苗木成活率、基径、树高和叶片净光合速率,研究了紫檀与柚木在干热河谷区的生长适应性。结果表明：紫檀可能较为适应干热河谷的气候条件,栽植早期通过人工抚育和肥料管理,可望达到较好效果;柚木的适应性较差,生长受限,人工栽植措施还有待进一步研究。

| Abstract: | In order to assess the growth adaptability of rosewood and teak in dry-hot valley regions, seedlings from Guangdong province were planted, the growth parameters such as survival percentage, basal diameter, tree height and net photosynthetic rate were determined, and the relative data were analyzed. The results showed that rosewood might adapt to the climate in dry-hot valley regions, which was possible to perform better if artificial tending and fertilizer management were applied in early planting stage. Teak worked badly in dry-hot valley regions contrarily, whose growth was limited, and its reasonable planting measures needed to be explored. |
