对青果期两年生西洋参１４Ｃ同化产物分配及根活力的测定表明，两年生西洋参于移栽前切除部分主根，后续生长中，参株发育正常，侧根及须根系发育良好，主根缩短；果期叶面喷施ＡＢＴ增产灵，能促进同化产物向根部转移，提高根系活力，尤其是提高侧根根系活力。可以认为，在培植短枝西洋参过程中，移栽前切除部分主根是一简便而有效的主要措施，而适时施用ＡＢＴ增产灵是必要的配套技术。
The results of 14C assimilation product distribution and root vigor of two-year-old American ginseng showed that two-year-old American ginseng was excised some main roots before transplanting. During the subsequent growth, the plantlets developed normally, the lateral roots and fibrous roots developed well and the main roots shortened. Surface spraying ABT Zeng Ling, can promote the transfer of assimilation products to the roots, improve root activity, especially to improve root activity of lateral roots. It can be considered that in the process of cultivating American ginseng, the removal of part of the main root before transplanting is a simple and effective main measure, and timely administration of ABT is the necessary supporting technology.
