Cephalotaxus mannii Hook. f. is a raw material resources of new medicine used for anti-cancer (leukaemia), which was found in 1970's in China. The natural resources of the plant is now being less and less. Protecting and establishing this raw medicinal resources base become more and more important. An investigation on the early growth performance of a 14-year-old plantation of C. mannii under un-extensive management was carried out at Jianfengling Forest Region, Hainan Province of China. It was showed that the mean annual increment (m.a.i.) was 0.42 cm in DBH, 0.39 m in tree height, 0.72m3 in volume (o.b.v.) and the total aboveground biomass (TAGB) was 7.678t/ha, the net production (excluding tree litter) was 0.548 t/ha/a with 833 individuals per ha in tree density. Although the stand productivity was low, the economic value of the medicine was high up to 800 thousand Yuan(RMB) per ha according to the harringtonine and homo-harringtonine in the bark biomass and their market price in 1989. Finally, the cultivating prospect of C. mannii also been discussed in this paper.

通过对海南粗榧早期生长特性的研究,表明该树种属中等生长速度类型。14年生幼林(833株/ha)年平均胸径生长量0.42 cm,树高0.39 m,材积0.72 m~3/ha,地上部分总生物量为7.678 t/ha,净生产力为0.548 t/ha·a。尽管生产力水平较低,但其经济价值很可观,桉树皮生物量中含的三尖杉酯碱和高三尖杉酯碱的价格计算,其药用价值近80万元/ha。若适当增大种植密度,并进行集约经营管理,提高生产力水平,在短轮伐期经营方式下,其经济价值可望能提高6倍以上。
