优良观赏树种绣球荚蒾硬枝扦插繁育技术研究

Study on Hardwood Cutting Propagation Technology of Viburnum macrocephalum, an Excellent Ornamental Tree Species

摘要: 为增加青海省绿化树种的品种，本文对引种驯化表现良好的绣球荚蒾进行扦插繁育技术研究。通过正交试验设计，探究扦插基质、扦插时间、采穗部位3个影响因素对扦插生根率、株高、生根数量的影响，并筛选出最优组合。结果显示：9月份采集一年生枝条，中部制成插穗，在国产泥炭土中扦插，平均扦插成活率能达到60%以上，是可推广的繁育方式。

Abstract: In this paper, in order to increase the variety of greening tree species in Qinghai province, the cutting propagation technology of Viburnum macrocephalum with good introduction and domestication was studied. Through orthogonal experimental design, the influence of three factors, cutting substrate, cutting time and cutting position, on cutting rooting rate, plant height and rooting number was explored, and the optimal combination was screened out. The results showed that in September, the annual branches were made into cuttings in the middle, and the average survival rate of cuttings in domestic peat soil could reach more than 60%, which was a breeding method that could be popularized.
