求翻译：如果挖掘过程中根系不在同一个平面内，以某一较长水平根和垂直主根组成的平面为剖视面，把其它根系投影到该平面最终以二维平面来表达根系的空间形态。是什么意思？

Excavation within the root not in the same plane, the plane consisting of a long horizontal roots and vertical taproot cutaway surface, the other root projection to the plane and the final two-dimensional plane to express the spatial form of the root.

If in the excavation process the root system in the identical plane, take some long horizontal root and the vertical main root composition plane as a sectional plane, projects other root systems to this plane finally expresses by the two-dimensional surface the root system the spatial shape.

If the root is not in the same plane in the mining process, a long horizontal and vertical plane is composed of main root sectional plane, projected onto the plane eventually to other root root space of expression to a two-dimensional plane.
