摘　　要：通过对红松人工林进行截顶和修枝2种修剪试验，研究不同修剪方式对红松生长量的影响，结果表明：密度适中的林分截顶后能促进林木直径的生长，试验区比对照区提高了30.8%；适当的修枝（修去枯死枝和下层1~2轮活枝）不仅可以提高林木的质量，还可以提高林木直径的生长量。Through top cutting and pruning on Pinus koraiensis plantation,effects of two kinds of pruning methods on growth of Pinus koraiensis were studied.Result shows that the growth of diameter of forest trees were promoted after top cutting with moderate density and the test area increase by 30.8% than that of the control area;proper pruning （prune the dead branches and 1-2 round living branches in the lower part）can not only improve the quality of trees,but also increase the growth of trees in diameter.
