开展忍冬科观赏植物雪果(Symphoricarpos sinensis)温室硬枝扦插繁育技术研究,探讨扦插时间、扦插部位、插穗处理方法及扦插基质对生根率及生根数量、根系长度的影响,得出以下结论:最佳扦插时间为秋季(10月),最佳扦插部位为1年生枝条下部,插穗最佳处理方法为清水浸泡30 min,最佳扦插基质为东北泥炭+净沙(1∶2)的混合基质。
The research on the hardwood cutting propagation of Symphoricarpos sinensis in the greenhouse was carried out. The effects of cutting time, cuttings, cuttings treatment and cutting medium on the rooting rate, rooting number and root length were discussed. The conclusions were as follows: The best cutting time was in autumn (October), and the best cuttings were in the lower part of 1-year-old branches. The optimum treatment of cuttings was immersion in clear water for 30 min, and the best cutting substrate was mixed matrix of peat + net sand (1: 2) in Northeast China.
