沙棘抹芽再扦插技术研究
- 文献标志码:
- A
- 摘要:
- 为促进扦插时产生的抹芽的再利用,避免优质种质资源的浪费,本文通过对不同品种的抹芽进行再扦插试验,探讨了抹芽插穗长度与扦插成活的关系,以及生长调节剂对成活率及生根量的影响,同时对移栽后移栽成活率、越冬成活率进行了调查统计。结果表明:品种间试验显示,‘深秋红’及‘雄株’因树势好、抗逆性强表现最优,成活率达90%以上;同时在抹芽再扦插中,以5~7 cm插穗为最优长度,3~5 cm表现适中,而2~3 cm表现不明显;同品种、同长度的抹芽插穗,在双吉尔-GGR绿色植物生长调节剂作用下,GGR对5~7 cm及3~5 cm生根率达90%以上,而ABT对各长度影响未达到90%,因此GGR生根剂成活率和生根量明显高于ABT生根粉处理。
