摘要
由于江苏地区常绿木兰科观赏树种缺乏,急需引种该类树种满足绿化需要,为此,从江西林业站引种4种木兰科常绿树种(乐东拟单性木兰Parakmeria lotungensis,红花木莲Manglietia insignis,乳源木莲Manglietiayuyuanensis,乐昌含笑Michelia chapensis)的种子,在南京郊区进行引种育苗试验,观察种子发芽特性,4种树种在大田条件下苗期发育基本正常,对4种树种的苗期物候特性、生长规律和抗寒性作出统计分析,认为经适当的养护管理,在南京郊区以及亚热带丘陵地区及相关区域可以进行大田育苗。
In order to resolve the problem that Magnoliaceae evergreen trees lack in landscaping, so we have done the experiment that four evergreen species of Magnoliaceae family have been introduced from forestry seed experimental stand of Jiangxi. Through the experiment we have researched seed＇s germination characteristics and growth regulations of seedling and cold resistance in emergence stage of seedling. We also draw the conclusion that under the proper nurture condition, these seeds can germinate on the fields seedling growth normally.
