分析了不需要完全挖出根就能测定一级侧根长度,主根及其侧根的总长度,根系向土表投影的方法。这个方法是建立在研究树种根的结构规律的基础上的。
The method of measuring the length of the primary root, the total length of the primary root and its lateral root, and the root system projecting to the soil surface without the need of completely digging out the root is analyzed. This method is based on the study of the structural rules of tree roots.
