David Robson says planting the root ball this way will improve growth.

罗宾逊表示，通过这个方式种植后将加速植物生长。

With a newly planted tree, the roots have not yet spread out from the root ball.

对于一棵新种植的树，它的根尚未从根球中散开。

So maybe butterfly it first and then measure how tall your root ball is. Then dig your hole.

所以，先将根系切瓣，然后测量一下高度，然后再挖坑。

But you do have to remember by butterflying, you are cutting down the overall height of that root ball.

但是你必须记住，通过切瓣降低了球根系的整体高度。

So his advice is to pull the plant out of the container, then cut the bottom half of the root ball into four parts.

所以，他建议将植物从容器中取出来，将底下一半的球状根系切成四部分。

If you dig individual holes, prepare a hole that is 2 to 3 times as wide as the root ball but only as deep as the root ball.

若你挖一个单独的坑的话，直径必须要是根系的2 ~ 3倍宽，但是深度只要和根系差不多就可以了。

The basic principle is though three root ball screw control platform, by the measurement of nozzle, three motor to adjustable height accordingly, easily implemented leveling!

其基本原理就是平台通过三根滚珠丝杠控制，上面对应三个电机，经过喷头测量，三个电机相应调节高度，很轻松实现了调平。

And so notice that when you are at speeds above that that you are exclusively in domain two and your terminal speed is proportional to the square root of the radius of the ball bearings.

应当注意的是，当,速度大的时候，是在,区域2中，终端速度和,这些滚珠的,√r成比例。
