回复 4# 雪莽一苗
搜到一篇关于根接的技术性文章：http://www.hainsroses.com/propagating/root%20grafting.html
看得不是很懂请高手翻译，不过里面似乎提到根接的目的是帮助接穗成长（和一般嫁接一样），然后促使接穗成熟生出自己的根
初步推断应该覆土超过接根接部位
其他资料先贴一下，有兴趣的同学可以一起研究下根接，我只是想知道根接和一般嫁接相比而言究竟有什么优点。

第四としては根接ぎである。適当な台木が得難いときに行われているが、根接ぎは増殖のためより、栽培樹の樹勢回復の目的で行われる場合のほうが一般的である。

The only time nurse grafting makes sense is when you eventually want the scion to root in. Many fruit trees including citrus, grape vines and even roses are grafted or budded for a specific reason. The understock may impart a degree of dwarfness, disease or nematode resistance or a superior root system. You don't want the scion on its own roots. In the case of budding, the crew is kept busy in the Summer time with no special facilities required. Many trees result from one budstick.
Nurse grafting is labor intensive and requires a longer production period. It is only practiced when there is simply no other alternative.

Because hybrid fruit trees do not produce an offspring that is also hybrid, the most popular method of reproducing hybrid fruit trees is through cuttings. But some cuttings will not root on their own. In this case, horticulturalists will graft roots onto the cutting so that it will survive until it can grow its own roots. The resulting sapling is then planted with the graft below the soil line. Eventually, the grafted roots die, and the tree's own roots take over the job of nurturing the tree. This type of grafting is known as root grafting or nurse grafting. This is a popular method for grafting apple trees.
另贴一篇介绍嫁接技术的文章，图文并茂我觉得很不错，但里面没有提到根接：http://www.ces.ncsu.edu/depts/hort/hil/ag396.html |
