采用短穗根接和短穗扦插 ,研究了杉木无性快繁技术 ,结果表明 ,此技术是可行和有效的 ,可提高繁殖系数 3～ 4倍。短穗根接绑带、不绑带均可。 3～ 5cm带顶芽短穗扦插与常规穗条扦插比较 ,其主要生长指标无差异 ,可用于生产性育苗。不带顶芽段不论是短穗根接还是短穗扦插 ,苗木质量均差于带顶芽段 ,并均需进行除萌 ,可在选优、建圃初期应用 ,以扩大繁殖系数。短穗扦插必须细致整地、适当早插、保湿、精细管理 Using short-spike root and short-spike cuttings, asexual propagation of Chinese fir was studied. The results showed that this technique was feasible and effective, and the multiplication coefficient could be increased by 3 ~ 4 times. Short ears then take the strap, not strap can be. Compared with the conventional cuttings of 3 ~ 5cm cuttings with short buds of top buds, the main growth indexes were the same and could be used for productive nursery. Without the terminal bud segment Whether short stalk or short cuttings, the quality of seedlings are worse than the top bud segment, and are required for the addition of adorable, can be selected, the initial application of nursery to expand the breeding coefficient. Short cuttings must be meticulously planted, appropriate early insertion, moisturizing, fine management
