促进根系发达具备发达的根系是苗木出圃后成活的关键。在育苗过程中，各种繁殖苗形成的根系简单、稀疏，有效根系少。可通过适当移植，促进侧根、须根的生长，加大根茎比，使起苗时不易伤根，栽植时成活率髙。显著的例子是，从山区 直接移栽10多年生、高2~3^的油松、白皮松大苗，由于没有经过移植，与苗木基地培养的经过3~4次移植断根的同规格苗木相比，根系不发达，根量少，在绿化中使用时成活率明显偏低.树势恢复缓慢。

实现树冠丰满丰满的树冠是园林苗木提供遮阴、发挥美化功能的先决条件。 苗木基地生产中，株行距的大小直接影响树冠的发育。落叶树栽植过密，会造成骨干枝发 育受阻，出现偏冠现象；常绿树栽植过密，会出现下部和内膛枝叶枯死，影响树形美 观。因此，根据苗木的生长特点，适时调整栽植密度，恰当地进行移植，才能培育出 枝条发育匀称、树冠圆润整齐的优质苗木。同时，在移植过程中，可对根系与树冠进 行必要的合理修剪.人为调节地上与地下部分生长的平衡，为生产规格整齐、枝叶繁 茂的优质苗木提供保证。
