阔叶低产林择伐改造林冠下人工更新红松林,通过择改后再进行幼林抚育,更新后7～9年进行透光抚育和适时伐除上层保留木,可以形成以红松为主的稳定的阔叶红松林。并推导出了适时伐除上层木的时间公式为:T=19.6729-0.4448D-0.0077N。
Broad-leaved low-yielding forest selective cutting transformation artificial regeneration of the Korean pine forest, through the re-election after the young forest tending, 7 to 9 years after the renewal of light transmission and timely removal of the upper retaining wood can be formed mainly to the stability of red pine Broad-leaved Korean pine forest. The time formula of timely cutting upper layer wood was derived as follows: T = 19.6729-0.4448D-0.0077N.
