摘要 以金边瑞香为试验材料,采用正交试验方法,研究了不同浓度IAA、IBA、NAA及扦插基质花泥、海绵、珍珠岩对金边瑞香水培扦插成活及生根的影响。结果表明,生根剂种类、生根剂浓度及扦插基质对金边瑞香扦插成活及根长有显著影响,对生根数量影响差异不显著。生根剂采用IBA处理平均成活率达80.00 %,1 000 mg/L的生根剂处理平均成活率达80.55%,花泥扦插处理平均成活率达89.33%。6号组合IBA+1 000 mg/L+花泥扦插成活率为94.00%,明显高于其他组合(P<0.05),达到了提高扦插成活率的目的,值得应用推广。

Abstract Using the orthogonal experimental design method, the effects of different concentrations of IAA, IBA, NAA, as well as cutting medium such as floral foam, sponge and perlite on the cutting survival and rooting of Daphne odora var.marginata Mak were studied.The results showed that: the type of rooting agent, the concentration of rooting agent and the cutting substrate had significant effects on the survival and root length of Daphne odora, but there was no significant difference in the number of roots.The average survival rate of rooting agent treated with IBA was 80.00%, the average survival rate of rooting agent treatment with a concentration of 1 000 mg/L was 80.55%, and the average survival rate of floral foam cutting treatment was 89.33%.The survival rate of No.6 combination IBA+1 000 mg/L+floral foam cuttings was 94.00%, which was significantly higher than other combinations (P<0.05).It achieved the purpose of improving the cutting survival rate and was worthy of application and promotion.

花卉水培属于无土栽培的一种,是20世纪60年代世界农业“绿色革命”以后,迎来的一场新的“种植革命”[1]。花卉水培是新一代高科技农业项目,通过对普通的植物、花卉进行人工驯化,使花卉能在水中长期生长。水培花卉上部分花香满室,下部分栽培缸鱼儿畅游,具卫生、环保和节省人工劳动的特点,也被称为“懒人花卉”[2]。此外水培花卉还具有很多其他优点,如:观赏性非常强,可同时赏花、观根和赏鱼;其次水培绿色环保,易于管理,约1个月换一次水和营养液就能维持植物生长[3]。水培花卉平时均在静水水池中养护,待出售时才装入透明水培容器内。……
