摘要
针对生产中北美冬青扦插繁殖生根率低的问题,以引进的北美冬青品种‘奥斯特’(Oosterwijk)为试材,在武汉地区就不同生根激素处理、扦插时间、插条选择等对北美冬青硬枝扦插的影响进行初步研究。试验结果表明,武汉地区在进行北美冬青扦插繁殖时,宜在秋季剪取北美冬青健壮硬枝,选其基部到中部的枝条部分作穗条,扦插时用911生根快蘸粉剂1进行根部快蘸后再扦插,可以保证80%以上的生根率。试验研究结果为北美冬青在华中地区的推广发展提供参考。
Aimed at the problems of the low rooting rates of Ilex verticillata when propagated by cuttings m the actual production, we conducted preliminary studies on the effects of different rooting hormone treatments, different cutting time, choice of cuttings, etc. on the rooting rates of the hardwood cuttings, using the introduced elite cuhivar ＇Oosterwijk＇ as the experimental material in Wuhan area. The results showed that the cutting measures, including cutting propagation in the autumn, choosing the basal to the central part of strong hardwood branches as the cuttings and quickly dipping the cuttings into the first powder of ＂911＂ rooting powder before cutting propagation could guarantee that the rooting rates were above 80%. The experimental results provided the reference for the promotion of Ilex verticillata in central China.
