植物地下部分的研究与地上部分相比一直较为薄弱，这主要归因于有效研究方法的相对缺乏以及新技术、新手段应用的滞后。概要介绍了植物地下生物量的主要测定方法：挖掘收获法、钻土芯法、内生长土芯法、根冠比法、同位素法、元素平衡法等，并对各个方法的优缺点进行了简单评述。介绍了微根窗法、地面穿透雷达法、核磁共振成像法、X－光根系扫描分析系统等新技术、新方法，对实际操作中不同方法的选择提出了自己的观点。 |

The understanding on the belowground part of plants is much less explicit than that on the aboveground because available methods are relatively scarce and some new methods are not effectively used. Common-used methods, including excavation methods, monolith methods, auger methods, ingrowth cores methods, root/shoot ratio methods, isotopes methods, element balance methods, were respectively introduced and evaluated. New techniques in studies on belowground including minirhizotron, ground-penetrating radar, nuclear magnetic resonance imaging, X-ray scanning root analysis system were introduced. |
