- 摘要:
- 以黔灵山冬青不同时段的插穗为试材,采用完全随机区组设计,研究了在全光照自动喷雾条件下不同浓度的IBA钾盐溶液、NAA钾盐溶液、荷尔蒙顿粉状剂处理对其扦插生根效果的影响。结果表明:9月采的枝条生根效果最好;与对照相比,生根剂处理能显著提高插穗的生根率、平均根数和平均根长。IBA-K液体1000 mg/L 快蘸20 s可极显著提高插穗生根数和平均根长。5000 mg/L IBA-K液体与荷尔蒙顿2号混合使用生根率最高,高达69%。
- Abstract:
- Taking cuttings of Ilex qianlingshanensis C.J.Tseng as test materials,used completely randomized block design,the effect of cutting propagation with different concentrations of IBAK solution NAAK solution and hormones on the rooting were studied in automatic spray condition.The results showed that September was the best cutting time;compared with the control,the rooting agent could significantly increase the rooting rate,root number and root length.A 20 s quick dip in 1000 mg/Lof IBA-K for rooting cuttings could significantly increase the root number and root length.The cutting rate of cuttings treated with 1000 mg/L of IBA-K mixing with Hormone 2 was the highest of which was up to 69%.-
