用嫁接繁殖的桂花苗木,栽植成活率低,而表现最突出的是嫁接部位不牢固,接口自然分离或受风吹、人为摆动等均能使砧、穗脱离死亡。通过多年的栽培试验,使桂花嫁接苗的栽植成活率保持在90%以上。其操作要点如下:首先,嫁接时接口要低,接活后,除进行通常的管理外,应在接穗第一次抽梢停止后,第二次抽梢前进行“培土育新根”,即
With the grafted sweet-scented osmanthus seedlings, planting survival rate is low, but the most prominent performance is the grafting site is not solid, the interface of natural separation or by the wind, artificial swing can make the anvil, spike from death. Through years of cultivation experiments, the survival rate of the osmanthus grafted seedlings maintained at 90%. The operating points are as follows: First of all, when grafting the interface is low, then live, in addition to the usual management, should scion the first stop after the shoot, the second shoot before the “training soil new roots”
