摘要：为了解花榈木林冠下造林效果，以1年生花榈木实生苗在不同坡向、坡位的杉木林下进行造林，调查了花榈木生长量，结果表明，1年生花榈木苗木成活率高，生长良好，不同坡向、坡位的林分环境因子存在差异，但在1个生长季节内对花榈木苗木成活和生长的影响没有规律性，需要进行长期观测与研究。

Abstract： One-year old Ormosia henryi Prain seedlings were planted under Cunninghamia laceolata plantations at different slope direction and slope position to understand the afforestation effect according to growth indicators. The results showed that the seedlings had a high survival rate and good growth， and the stand environmental factors were different in different slope direction and slope position. However， the effects on the survival and growth of seedlings during a production season are irregular， this means that a long-term observation and research are needed.

花榈木主要分布在我国长江以南的安徽、浙江、贵州、江西、湖北等地区，是我国二级保护植物[1]，野生资源少，且分布零散。（剩余3703字）
