摘要
用95％H2SO4浸鹤望兰种子（1：10体积比混合）3－5min，能有效地除去种皮表层蜡质，疏松种皮，不损伤种子，缩短萌芽时间。1NNaOH处理效果次之。95％乙醇洗脱无明显效果。幼苗移栽前适当处理（代森锌700倍+0．02mg／LNAA浸泡1h）能有效地抵御病害，提高幼苗成活率。栽培基质以透水保湿多肥的酸性土最好。此外，遮阳（60％～80％）是幼苗安全越夏的重要条件。
Dipping the seeds of Strelitzia reginae into solution of 95% H2SO4 (1/10 volume of the seeds) for 3-5 minutes gave the best result to accelerate germination, which softened foe seed coat, removed the surface wax easily without causing the seed damage. The treatment with the solution of IN NaOH take the second. place, but the treatment with 95% alcohol was not so effective on the germination. When the seedlings were treated with a combination of Zineb with 700 times diluted solution and 0. 02 mg/L NAA for one hour before being transplanted. They effectively resisted diseases and had a higher survival rate. A fertille medium with permeable acid soil is also necessary for the seedling growth A shading of 60%-80% is an important condition for the seedlings to survive in the hot summer days.
