摘要
为研究蜡梅在秋冬季嫁接的关键技术,本研究以蜡梅的不同品种为试材,研究了不同嫁接时期、不同砧木树龄、不同接穗部位对蜡梅嫁接成活率的影响。结果表明,在秋冬季,9月下旬的嫁接成活率显著高于10月中旬、10月下旬和11月中旬;随着时间的推移,蜡梅的嫁接成活率呈逐渐下降的趋势;不同接穗部位对蜡梅嫁接成活率的影响无明显的规律;以多年生实生苗作砧木的嫁接成活率(56.03%)显著高于一年生实生苗(21.41%)。本研究为蜡梅在秋冬季的生产繁殖与引种扩繁提供技术指导。
Taking different varieties of wintersweet(Chmonanthus praecox) as test materials, the influence of different grafting times, stock ages, and scion positions on the survival percentage of wintersweet grafting were studied, in order to study the key techniques of wintersweet grafting in autumn and winter. The results showed that in autumn and winter, the grafting survival percentage of wintersweet in late-september was significantly higher than that of mid-october, late-october, and mid-november;with the passage of time, the survival percentage of wintersweet grafting showed a gradual downward trend;there is no obvious regularity of the effect of the different scion positions on the survival percentage of wintersweet grafting in autumn and winter;the survival percentage of grafting with perennial seedlings as rootstocks(56.03%) was significantly higher than that of annual seedlings(21.14%).This research provides technical guidance for the production, reproduction, introduction and expanding of wintersweet in autumn and winter.
