采用正交试验设计，研究遮阳、施肥对小省藤苗期生长的影响，结果表明，（1）遮阳和施肥的交互作用对小省藤地径和苗高有一定的影响，但影响不显著；（2）在因素主次方面，遮阳度（A）对地径、苗高的影响最大，施肥[尿素（C）]次之，而施肥[过磷酸钙（B）]对地径、苗高生长均有抑制作用；（3）综合各因素水平对小省藤苗生长指标的影响，确定的最佳组合为A2 B1 C2，即75﹪的遮阳度、施用20 g尿素、不施用过磷酸钙组合。

The effect of shade and fertilizer on Calamus gracilis were analyzed by orthogonal experiment.The re-sults showed that the interaction of shading and fertilization have some impacts on seedling height and ground diam-eter of Calamus gracilis, but not significant; Shade was the key positive factor, urea was the secondary positive factor, and calcium superphosphate was negative factor.The best combination of all these factors was A2 B1 C2 , namely shade with 75 %, urea with 20 g and without calcium superphosphate.
