采用楠木撒播与条播及遮荫与不遮荫的育苗对比试验,结果表明:楠木苗木生长可分为出苗期、幼苗期、速生期和生长后期4个阶段。出苗期,从3月上旬~4月上旬;幼苗期,从4月上旬~6月上旬;速生期,从6月上旬~10月上旬;生长后期,从10月中旬~12月中旬。不同播种方式对苗木出苗率有一定影响,条播出苗率高于撒播;对苗木高和地径生长影响不大,方差分析均未达到显著差异。遮荫对苗木生长有较大影响,苗高,遮荫为不遮荫的109.3%;地径,遮荫为不遮荫的104.4%,方差分析均达到极显著差异,楠木育苗需要遮荫。
採用楠木撒播與條播及遮蔭與不遮蔭的育苗對比試驗,結果錶明:楠木苗木生長可分為齣苗期、幼苗期、速生期和生長後期4箇階段。齣苗期,從3月上旬~4月上旬;幼苗期,從4月上旬~6月上旬;速生期,從6月上旬~10月上旬;生長後期,從10月中旬~12月中旬。不同播種方式對苗木齣苗率有一定影響,條播齣苗率高于撒播;對苗木高和地徑生長影響不大,方差分析均未達到顯著差異。遮蔭對苗木生長有較大影響,苗高,遮蔭為不遮蔭的109.3%;地徑,遮蔭為不遮蔭的104.4%,方差分析均達到極顯著差異,楠木育苗需要遮蔭。

Contrast experiments of broadcasting and line drilling,sunshading and non-sunshading seedling of Phoebe bournei were made,the results showed that the seedlings growth of Ph.bournei can be divided into four stages as follows: emergence stage,seedling stage,fast-growing period and later growing stage.Emergence stage was from early march to early April;Seedling stage was from early April to early June;Fast-growing period was from early June to early October;Later growing stage was from middle of October to middle of December.Different ways of seedling had certain influence on germination rate,germination rate of line drilling was higher than that of broadcasting,and they had not great influence on growth of seedling height and ground diameter,variance analysis was not significant differences.Sunshading has great influence on seedlings height growth,seedlings height with sunshading was 109.3% of non-sunshading,and ground diameter was 104.4%.Variance analysis was all has significant differences,so seedling of Ph.bournei should be took sunshading.
