白玉兰(Magnolia denudata Desr)为落叶乔木,枝叶繁茂,树形美观,花色银白,气味芳香,是一个珍贵用材和观赏树种。在浏阳县大围山区,多零星分布于海拔600～1000米的溪谷两旁。因受山区小气候、地形和森林环境等因子影响,只开花难结果。1980～1982年,我场进行了白玉兰截干分蘖育苗试验,获得了良好的成效。三年中截干分蘖50蔸,得幼苗154株,成活率达98%,平均苗高0.55米,平均根径0.51厘米,与同年育的实生苗相比,高
Magnolia denudata Desr is a deciduous tree, lush foliage, beautiful tree, white color, aroma, is a precious timber and ornamental tree species. In Liuyang County Dawei mountainous area, mostly sporadically distributed at 600-1000 meters above sea level on both sides of the valley. Due to mountain microclimate, terrain and forest environment and other factors, only flowering difficult results. From 1980 to 1982, we carried out the experiment of transplanting and tillering Magnolia grandiflora on tillering seedlings, and achieved good results. Truncated tillering in three years 50 蔸, 154 seedlings have been obtained, the survival rate of 98%, the average seedling height of 0.55 meters, the average root diameter of 0.51 cm, compared with the same age seedlings, high
