半硬枝这个术语在(美)哈特曼等的著作中曾经提到,我们借以特指树木基本停止顶端生长,而叶柄尚未产生离层时期采集的插条。既不同于在生长期采集的半木质化的软枝,也不同于在休眠期采集的硬枝。我国江淮一带群众育苗就有所应用,我省的毛白杨以及花椒扦插试验所用材料,实际上也是半硬枝。近年,我们又用若干针阔叶树种的半硬枝插条扦插繁殖,也都取得良好的结果。但是,对于这种材料的性质,尤其是扦插技术还需要深入的研究。这是笔者撰写本文和大家共同探讨的目的。
The term semi-hardwood was mentioned in the work of Hartman et al., In which we specifically refer to trees that essentially halt the growth of the top, while the petiole has not yet produced the cuttings collected during the delamination. It is different from the semi-lignified soft branches collected during the growing season and the harvested branches during the dormant period. China’s JAC area has been applied to the mass nursery, the province of white poplar and pepper cutting test materials used, in fact, is also a semi-hard branches. In recent years, we have also used several softwood species of semi-hardwood cutting propagation, but also achieved good results. However, the nature of this material, in particular cutting technology needs further study. This is the author to write this article and we discuss the purpose.
