| 摘 要： | 本文研究了4个遮光处理（即全光照、遮光度40％、遮光度60％和遮光度70％）下闽楠一年生大田播种育苗苗木保存率以及苗木生长情况．结果表明：闽楠幼苗苗木保存率随遮光度的递增而增加；遮光度为70％的处理下，苗木保存率最高，达到了83．9％，而全光照时则反之．仅有42．2％；不同遮光度问闽楠幼苗苗高和地径生长差异均极显著；60％遮光度下闽楠大田播种育苗效果最佳。

| Abstract: | In the research, four shading treatments were set, including the treatments with shading degrees at 0, 40%, 60% and 70%, in order to explore storage rate and seedling growth of annual Phoebe bournei. The results showed that the storage rate is growing upon shading degree. In the research, for example, storage rate reached the peak with the shading degree at 70%, and only 42.2% with shading degree at 0. In addition, seedling height and ground diameter showed extremely significant differences among treatments, and the treatment with shading degree at 60% was the best. |
