摘　　要：本试验通过对北五味子长枝不同节位雌花率调查分析，确定长枝适宜的剪留长度为剪留8个节：并对不同长枝留量植株的平均单株产量进行调查分析，确定长枝适宜的剪留量为11-15。采用3年生根蘖植株进行平茬更新修剪，并将此两项修剪指标应用到修剪过程中，并对其生长势与同年生实生苗为对照，结果表明，根蘖苗的平茬更新修剪对植株生长势的影响效果明显优于常规修剪。In this test, average female flowers rate per jiont of Schisandra chinensis Baill is investigated to ascertion that the remaining length is 8 jionts. Average production per plant of Schisandra chinensis Baill remaining different quantity of long branch is investigated and analyzed to ascertion that the remaining quantity is iI to 15. This two former indexes are applied to the update stump pruning of 3-year-old tiller plants in the next year comparing with same-year-old seedlings at the side of circumstance of growth. The result shows that the influence of the update stump pruning on the circumstance of growth is superior to conventional pruning.
