摘要(Abstract)：

大叶藻(Zostera marina L.)是全球分布最广泛的海草之一,曾在山东半岛沿海有广泛分布。然而,自1980年代开始,受自然因素和人类活动的影响,大叶藻场严重衰退,导致黄海近岸海洋生态系统恶化,渔业资源锐减。本研究以中国黄海海域(山东半岛)大叶藻为研究对象,研究不同温度、春化作用时间对大叶藻种子萌发和不同播种深度对种子成苗率的影响,进行了幼苗培育,研制开发幼苗移栽装置和技术。结果表明:春化处理温度对大叶藻种子萌发率具有显著影响(p<0.01),4℃春化处理50d的大叶藻种子萌发率最高,平均达55.3%;埋植深度对大叶藻种子萌发率和幼苗成苗率有影响,埋植深度0.5~2.5cm时大叶藻幼苗的出苗率相似,但显著高于埋植深度3~4.5cm的成苗率(p<0.01)。依据这些研究结果,成功培育大叶藻苗7.6万株,生长110d,平均幼苗长度达16.3cm,最大长度达22cm;研制了育苗杯大叶藻苗移栽装置,实现了从水面高效栽植大叶藻幼苗。
