以乔木银桦(Grevillea robusta)为砧木,地被银桦(Grevillea baueri)为接穗嫁接可形成垂枝银桦,为园林绿化提供新奇的景观树种。4个参试的地被银桦品种在春、夏季嫁接容易成活。接穗保存时间和接穗留芽方式是嫁接成活的关键因子,接穗保存时间以随采随接成活率最高,低温条件下保存3d穗条失去活力,接穗留芽方式以腋芽生长<10cm,保留全部腋芽最好,成活率达61.3%。砧木嫁接口高度100cm时,有利于新芽生长。
With Grevillea robusta as the rootstock and grafted by Grevillea baueri as a scion, weeping silver birch can provide a novel landscape tree species for landscaping. 4 test sites are silver birch varieties in the spring and summer grafting easy to survive. Scion preservation and scion retention were the key factors of grafting survival. The survival time of scion was the highest with random access, and the storage of 3d spike was lost vitality under low temperature. Best, survival rate of 61.3%. Rootstock grafting interface height of 100cm, is conducive to the growth of new shoots.
