白皮松等级划分
在苗木行业，经常说一级国槐，二级白蜡，这些树一级指的是干直，帽圆为标准。而遇到白皮松就很难说清一级二级三级是什么标准，今天我就根据在“红绿园林白皮松基地”的工作经验为大家说说白皮松等级如何划分。
1，精品白皮松
是指白皮松冠副非常大，数值接近白皮松的高度，比如要求2.5米高,2米的冠幅,用眼睛看接近球型,树枝密度很密,站这边看不到另外一面,如下图就是精品白皮松.这种必须留足够大的株距,才能保证如此大的冠幅,土地利用率较低,树价较高.

2, 一级白皮松
一级白皮松,指的是白皮松接近自然生长,树高和冠副比例接近2:1,远看塔型,落地冠,密度中上.如下图:

3, 二级白皮松
二级白皮松是指塔型,冠幅相对较小,高度和冠副比小于2:1,树枝较分散,密度较低,可以看到明显的树干,经常吧有点脱脚的也划入二级,如下图.

4,三级白皮松有点不像标准的塔型了,不多说,直接上图吧,
5, 比这更次的我们称这为“占地苗”，可以说就不讲树型了，
