以青钱柳1年生幼苗为对象，研究光照和施肥对其复叶性状、气孔特征和叶片解剖结构的影响。结果表明，光照及光照和施肥2因子的交互作用对叶片性状和解剖结构各指标有显著或极显著影响，施肥仅对叶片厚度有显著影响；全光照下青钱柳叶面积最小，叶片较厚，栅栏组织和海绵组织排列紧密，叶片气孔小而密；光照强度减弱使叶片面积增加，叶片变薄，比叶质量下降，气孔密度减小，气孔变长变宽；全光照下，复叶面积、复叶干质量和比叶质量随施肥量增加而增加，叶片厚度也有一定的增加。中等光照下施肥20 g/株处理的复叶面积和复叶干质量最大，说明中等光照且适量施肥是青钱柳幼苗生长的最佳条件。

One-year Cyclocarya paliurus seedling was selected as material to analyze the effects of light intensi-ty and fertilization on compound leaf traits,stomata characteristics and anatomical structure.The results showed that shading and interaction of shading and fertilization significantly affected all indices.However fertilization had only significant effect on leaf thickness.Without shading,the leaf area was smaller,but was thicker.In addition, the palisade tissue and spongy tissue of the leaf were compact under 100% sunlight condition,and the leaf had smaller and denser stomata.As the light intensity decreased,leaf area increased,and leaf thickness,leaf mass per area (LMA)and stomata density decreased.Accordingly,the stomata became longer and wider.Under 100%sunlight condition,fertilization resulted in the increase of the leaf area,leaf weight,LMA and leaf thickness.The greatest leaf area and weight were achieved in intermediate shading and 20.0 g/plant fertilizer.It was suggested that intermediate shading and fertilization was the optimal condition for the growth of C.paliurus seedlings.
