“帚状”欧洲鹅耳枥(Carpinus betula ‘Fastigiata’)为欧洲鹅耳枥选出的优良园艺品种,具有枝条稠密、向上生长的特性,树型呈塔形或柱形,耐修剪,可修剪成屏状绿篱作档风绿墙作空间分割,欧洲园林中应用普遍。本研究首次对国外引进的“帚状”欧洲鹅耳枥采用无喷雾接触套袋自保湿系统进行了半硬枝扦插繁殖研究,结果表明:IBA快蘸溶液处理能够显著提高“帚状”欧洲鹅耳枥插穗的生根率(p<0.01),其中以0.8%浓度处理效果最好,插穗生根率最大达100%,平均根数与根长也接近最大。由此获得该树种优化繁殖技术,为在国内进一步的推广应用奠定了基础。
“Broom ” Carpinus betula ’Fastigiata’ is an excellent horticultural variety selected for European hornbeam with a densely populated, upwardly growing tree with a tower or column shape, Can be trimmed into a screen-like hedge for the file wind green space for spatial segmentation, the European landscape in general. In this study, the semi-hard cutting propagation of “broom ” and European hornbeam introduced by foreign countries for the first time was studied. The results showed that: IBA fast dip solution treatment can significantly improve the The rooting rate of European hornbeam (p <0.01), of which 0.8% concentration treatment effect is the best, the rooting rate of cuttings up to 100%, the average number of roots and root length is also close to the maximum. The optimal breeding technology of the species was obtained, which laid the foundation for further popularization and application in China.
