红松人工幼龄林调控技术的研究

Study on the Regulation and Control Technique of Korean Pine Young Stands

皆伐迹地红松人工幼龄林的透光抚育，应实行上重下轻的综合透光抚育。均匀保留上层阔叶树和带状保留上层阔叶树，这2种抚育方式都是可行的。保留上层阔叶树500株/hm2]或略高于此较为适宜。伐去全部上层阔叶树和不伐上层阔叶树都不利于人工林的培育。

The light-felling of Korean pine young stands on clear cutting block should carry out the synthetic light-felling of cutting more in upper layers and fewer in lower layers. Evenly reserving broad-leaved trees in upper layer and reserving broad-leaved trees in upper layer in strip are all applicable. Reserving broad-leaved trees in upper layer for 500 individuals per hacter or a little over 500 individuals is suitable. Cutting all the broad-leaved trees in upper layer and cutting no broad-leaved trees are not benificial to the cultivation of artificial forests.
