摘要 [目的]探索衡陽地区蓝莓绿枝扦插越冬育苗技术,为蓝莓绿枝扦插育苗提供技术支撑。[方法]通过设置生根粉400倍液(2500mg/L)喷洒苗床、生根粉600倍液(1667mg/L)喷洒苗床、萘乙酸1000倍液(1000mg/L)喷洒苗床3种不同的育苗处理方法,对密斯帝、杜克、奥尼尔、雷戈西4个蓝莓品种的绿枝扦插越冬育苗技术进行研究。[结果]同一蓝莓品种采用不同育苗处理的成活率差异不大;同一育苗处理不同蓝莓品种的成活率差异较大,奥尼尔成活率最高,密斯帝次之,雷戈西再次之,杜克最低。4个蓝莓品种在秋冬季绿枝扦插后,叶片慢慢凋落,扦插成活苗翌年3月初开始萌发新芽,同一蓝莓品种不同育苗处理的扦插苗株高差异不大;同一育苗处理不同蓝莓品种的扦插苗株高差异较大,奥尼尔株高最大,雷戈西次之,密斯帝再次之,杜克最小。扦插300d以上,4个蓝莓品种扦插苗平均根数和平均根长均以生根粉400倍液(2500mg/L)喷洒苗床最好,生根粉600倍液(1667mg/L)喷洒苗床次之,萘乙酸1000倍液(1000mg/L)喷洒苗床再次之;从同一育苗处理来看,扦插苗平均根数和平均根长均以奥尼尔最好,雷戈西次之,密斯帝再次之,杜克最差。[结论]4个蓝莓品种在衡阳地区进行越冬扦插育苗是可行的,其关键是利用生根粉或相关激素进行育苗处理,注意保温保湿并防病害侵染,使插条能够安全越冬。
