短枝西洋参培植技术的研究

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，能促进同产产物向根部转移，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。

CULTIVATED METHOD OF SHORT ROOT AMERICAN GINSENG ( Panax quinqueflium )

The distribution rate of 14 C assimilated material and root vitality of two years old American ginseng at green seed stage were measured.An exploratory research was made by cutting part of main root and spraying ABT on leaves of American ginseng.The results show that with cutting part of main root out before transplant and then sticking them in the seedbed, the plant develop and grow normally and the lateral and fibrous roots grow well. Spraying ABT on leaves of the plant at seed forming stage accelerate the transfer of assimilated material to the root and enhance the root vitality,especially the lateral root vitality.It is considered that cutting part of main root out is major method and spraying ABT on leaves is a supplementary measurement.
