采用遮光网探讨不同遮光度对白木香种子萌发和幼苗生长的影响。结果表明：遮光度75％、50％条件下，白木香种子萌发时间最早，萌发率达到80％以上；自然光（ CK）条件下，萌发率最低，萌发时间最迟。不同遮光度对白木香幼苗生长有极显著影响，遮光度75％、50％条件下，白木香幼苗存活率较高，生长较迅速；遮光度90％条件下，白木香幼苗存活率最高，但生长较差；自然光（ CK）条件下，白木香幼苗存活率低，生长慢。说明在白木香育苗过程中，适当的遮光能够促进白木香种子的萌发和苗木的生长。

Using the shading net to probe into the different shading degrees on the effects of seed germination and seedling growth of Aquilaria sinensis( Lour.) Glg.The results showed that seed germination in the earliest time,germination rate reached more than 80%on the 75%,50%of shading degrees;under the natural light (CK),germination rate was the lowest and germination time was the latest.Different shading degrees of seedling growth of A.sinensis had significantly effects,on the shading degree is 75% and 50%, seedling survival rate was higher,and growth was rapid;in the shading degree 90%,seedling survival rate was the highest,but poor growth;and under the natural light ( CK) ,seedling survival rate is low,slow growth.These instruct that appropriate shading can pro-mote seed germination and seedling growth in the breeding process of A.sinensis.
