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%;不同遮光度间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。 In this paper, the preservation rate of seedlings and the growth of seedlings in one-year field planting of Phoebe bournei were studied under four shading treatments (ie full light, 40% shading, 60% shading and 70% shading). The results showed that: The rate of seedling increased with the increase of shading degree. The seedling preservation rate was the highest (83.9%) when the shading degree was 70%, while it was only 42.2% when it was full light. The seedling height The difference of diameter growth was extremely significant. The effect of sowing seedlings was the best under the condition of 60% shading.
