金叶国槐嫁接技术及园林应用

Grafting Techniques of Sophora japonica f.flavi-rameus and Its Application in Gardens

介绍了以国槐为砧木的嫁接方法培育金叶国槐新苗,分为砧木培育、嫁接、嫁接后管理3个部分,具体阐释了砧木培育过程中的采种、播种、砧木大苗培育过程;嫁接过程中的嫁接时间、接穗采集与处理、砧木处理,以及插皮接和芽接的嫁接方法;嫁接后的管理重点,即检查成活情况与解除绑扎物,抹芽、摘心、整形,水肥管理以及病虫害防治。在此基础上进一步分析了金叶国槐在园林中的应用,指出其应遵循生物学特性和美学原则,适当采取孤植、丛植、片植、列植的方式,也可以与其他树种进行综合配置,以求实现出色的景观效果。

The method of cultivating seedlings of Sophora japonica f.flavi-rameus on the basis of rootstocks of Sophora japonica Linn.was introduced in this study,mainly including rootstock cultivation,grafting and post-grafting management,specifically,seed collecting,sowing,and large seedlings breeding in the cultivation of rootstocks;grafting time,scion collection and treatment,rootstock treatment,as well as techniques of stump grafting and bud grafting;focuses of post-grafting management,such as checking the survival rate and untying colligations,bud picking,pinching,topiary work,water and fertilization management,disease and pest control.Then the application of Sophora japonica f.flavi-rameus in gardens was analyzed,and it was proposed that biological characteristics and aesthetic principles should be followed,proper planting patterns should be applied,such as isolated planting,group planting,mass planting,linear planting and so on,moreover,it could also be combined with other plant species to create outstanding landscape effects.
