摘　　要：毛红椿是楝科香椿属植物,其生长迅速,树干通直,素有"中国桃花心木"之称,是珍贵的用材树种,具有很高的经济价值和开发前景。通过不同遮荫处理对毛红椿幼苗生长影响的研究,结果表明:不同遮荫处理间毛红椿幼苗苗高和地径差异显著,适度的遮荫可以促进毛红椿幼苗的生长,说明毛红椿幼苗期有一定的耐荫性;遮荫可以明显提高毛红椿幼苗根系平均直径、小根长度、粗根长度、小根表面积和粗根表面积。Toona ciliata var. pubescens is a fast growing tree species with straight trunk, belonging to genus Toona, family Meliaceae. It is a valuable tree species, and has high economic values and developing foreground. Effects of shading on growth of T. ciliata vat. pubescens seedlings were studied and the results showed that there was significant difference of seedling height and ground diameter among different shading methods. And shading accelerated the seedling growth, this indicated that the tree species had shade tolerance, Shading was benefit for average root diameter, fine root length, thick root length, superficial area of fine roots, and superficial area of thick roots.
