在天然红松母树林内进行透光抚育,既可保持森林环境,又可将生长衰退林木清除利用。但广泛运用这种作业方式,不仅缺乏实施经验,而且象采伐强度、采伐木的选择标准、采伐的最佳间隔期等技术问题还未解决。为此,我们从1973年起,有计划地进行了透光抚育试验。研究的初步结果如下。 In the natural Korean pine tree light through tending, can maintain the forest environment, but also the growth and decline of trees removed. However, the widespread application of this mode of operation not only lacks experience in implementation, but also technical issues such as harvesting intensity, selection criteria for harvesting logs, and the optimal interval of harvesting have not yet been resolved. For this reason, we have carried out the tempering tending experiment since 1973. The preliminary results of the study are as follows.
