摘要
对我国引种栽培的紫檀属树种进行了系统调查 ,结果表明 :我国已引入紫檀属 8个树种 ,其中有6个种生长比较好 ,能正常开花结实。紫檀属树种引种于我国热带、南亚热带地区的红壤、砖红壤、沿海冲积土和沙壤上 ,大多数表现出较强的适应性 ,生长良好 ,能耐 0℃以上的短暂低温 ,抗 1 0级以下台风 ;而且生长迅速 ,在良好栽培条件下 ,中幼龄林木年均胸径生长量可达 2cm以上。紫檀属树种开始形成心材的年龄因树种而异 ,檀香紫檀、印度紫檀为 1 5～ 2 0年 ,古巴紫檀为 7年 ,马拉巴紫檀为 4年。紫檀属树种作为特类珍贵用材树种和园林绿化树种 ,在我国具有广阔的发展前景 ,建议各级政府立项开展种质资源的系统引进以及相关研究与推广工作。
Introduction and cultivation situation of Pterocarpus species was recently investigated in China. To date, six species of this genus have been proved to flower and fruit with good growth performance, from which it was demonstrated that Pterocarpus species are suitable to grow in sites such as red soil, latosol, coastal fluvisol and sandy soil with resistance to short period low temperature above 0℃, typhoon of below 10 class. In young or middle aged plantations at good sites, they grew more than two centimeters of diameter at breast height per year. The age of heartwood formation is different with species, for P. santalinus and P. indicus is normally fifteen to twenty years, while for P . sp. and P. marsupium is seven and four years, respectively. Pterocarpus species are of good perspectives for specific valuable timber production, and ornament or greening purpose planting program, thus sufficient introduction of their germplasm resources is recommended as well as relevant research on them for large scale development of Pterocarpus plantations.
