- 摘要:
- 以多年生流苏树桩、2 a生流苏实生苗、2 a生金叶女贞、2 a生大叶黄杨为砧木，选择营养充足带顶芽、营养充足不带顶芽、营养充足但芽眼不饱满3种接穗(III)，在4、6、8月份分别进行桂花嫁接试验，研究了不同砧木、接穗、嫁接时间对桂花嫁接成活率的影响。结果表明：选用与接穗具有较强亲和力的、生长活跃的2 a生流苏实生苗作为砧木，嫁接成活率最高；无论有无顶芽，只要是芽眼饱满的接穗，嫁接成活率都很高，但嫁接成功后，由于桂花新枝的顶端生长能力较为明显，因此营养充足并带有顶芽的接穗，生长更为迅速；嫁接最适宜的时间是在每年4月份左右，此时正处于桂花的萌发期，环境温度有利于形成层的旺盛分裂和伤口的愈合，此时进行嫁接成活率较高。
- Abstract:
- Taking perennial tassel tree stump,two years old tassel seedlings,two years old ligustrum and two years old euonymus as rootstocks，selecting three species of scion:nutritional adequacy with bud,nutritional adequacy with no bud and nutritional adequacy but no plump bud，the grafting test was conducted in April,June and August，the effect of different rootstock，scion，grafting time on the grafting survival rate were studied.The results showed that the highest survival rate of grafting appeared when we chosed two years old ligustrum that it was strong affinity with the scion and active growth.The grafting survival rate was very high when the bud was plump.The scion that nutritional adequacy with bud grows faster after the grafting because the new top growth ability was more obvious.The most suitable time of grafting was in April each year because it was in the germination period of Osmanthus fragrans and environment temperature favors the formation of layers of vigorous division and wound healing.
