看完别的文章后困扰我的问题

看了下球落地的问题

请问下什么叫落地  怎么落地啊

是把三角给砍了一点不留吗  留的话会有什么害处啊

```````````````````````````````````````````````````````````````````

还是说将三角用土全部埋起来   让土接触到接蕙的球球   那样的话  三角会自然脱落或枯萎的吗     球接触到土的情况下会发根的吗（下面的三角会影响它的自发根吗）

```````````````````````````````````````````````````````````````````

    还有就是如果要把木芯拔了是要拔得很干净  还是可以留那么一小部分（因为我喜欢用

刀割的  感觉割的不是很干净啊）
