金叶白蜡不同嫁接方法、接穗粗度与解绑时间对成活率的影响

Effect of Scion Diameter and Unbinding Time on Survival Rate of Fraxinus Aureus with Different Grafting Methods

以大叶白蜡作砧木,采用插皮接的方法观察地接和高接2种不同嫁接方、不同粗度的硬枝接穗和不同解绑时间,对金叶白蜡成活率的影响。结果表明:高接和地接2种不同嫁接方法中,地接的发芽率、成活率和保存率均高于高接的;5种不同粗度的接穗嫁接中,以0.8 cm粗的接穗嫁接效果最好,高接嫁接后第30 d解袋,接穗的成活率最高可达94%,地接的嫁接后第25 d解袋,接穗的成活率最高,但各时间段的成活率之间无显著差(P>0.5)。

Using Fraxinus macrophyllus as rootstock,the effects of two different grafting methods,ground grafting and high grafting,hard branch scions with different thicknesses and different debinding time,on the survival rate of Fraxinus macrophyllus were observed.The results showed that among the two different grafting methods of high grafting and ground grafting,the germination rate,survival rate and preservation rate of ground grafting were higher than those of high grafting.Among the five kinds of scion grafting with different thicknesses,the grafting effect of 0.8 cm thick scion is the best.The survival rate of scion can reach 94% at the 30th day after high grafting,and the survival rate of scion is the highest at the 25th day after ground grafting,but there is no significant difference between the survival rates of each time period(p<0.5).
