我们在1975年的乡土树种调查中,发现一种生长快、材质好的优良用材树种,当地群众叫毛椿,经鉴定为楝科香椿属的红楝子(Toona Sureni)。红楝子又名红椿,与香椿外形非常相似,其主要区别是:前者小叶全缘,全身无香味,子房有毛,蒴果表面有稀疏白色毛孔,种子两端有翅;后者小叶有锯齿,叶、皮有香味,子房无毛,蒴果表面光滑,种子上端有翅。据在我县与大庸、永顺等地调查观察和群众反映,过去红楝子资源比较丰富,但由于它的主干圆满通直,材质坚韧轻软,不翘裂,能耐腐,出材率高等特点,遭到了强度砍伐利用,到现在只分布在交通不便、人烟稀少的山区,散生于山腰、山麓、湾漕、沟谷、溪边和屋前屋后。红楝子是中性偏阴的树种,一般分布在阴坡、半阴坡山腰以下,阳坡山麓和湾漕、沟谷,溪边的杂木林中,常与楠木、
In our native tree species survey in 1975, we found a good growing timber material with good quality. The local people, Mao Chun, were identified as Toona Sureni from Toadstool. Toona sinensis, also known as red toon, toon and toon appearance is very similar, the main difference is: the former lobular entire, whole body without fragrance, ovary hairy, capsule surface with sparse white pores, the ends of the wings winged; Serrated teeth, leaves, skin aroma, ovary glabrous, capsule surface smooth, winged upper seeds. According to the investigation and observation by the masses in Dayong County, Yongshun County and other places, the past few years ago, the resources of Toona were abundant. However, due to the fact that its main trunk was straight and straight, the material was light and soft, not cracked and decay resistant. Higher characteristics, has been the intensity of deforestation, and now only distributed in the traffic inconvenience, sparsely populated mountain areas, scattered in the mountainside, foothills, bay waters, valleys, streams and front of the house. Toona sinensis is a neutral shade trees, generally distributed in the shady slopes, semi-shady hillside below the sunny foothills and bay troughs, valleys, stream side of the mixed wood, often with Phoebe,
