作者通过红松伐根断面圆盘年轻的检查,证明红松的生态类型,是属于耐阴性的。红松既属于耐阴性树种,它的耐阴数字,必经过实践的测光方法才能测得。作者于1958年在东北红松林区(小兴安岭的带岭及长白山林区)对于红松更新苗木进行测光研究。关于测光仪器选有两种:一为德国制造的鲁克司光度计,一为格劳开尔测光器。两种仪器配合使用,在12个红松林型内对于林冠下各年龄的红松更新幼苗和幼树进行实测,测得126株红松幼苗和幼树的相对最小耐阴性及相应的高生
The author through the Korean pine cuttings disc section of the young check to prove the ecological type of Korean pine, is a negative-tolerant. Red pine is both negative-tolerant species, its shade-tolerant figures, will be measured by the practice of the metering method. The author in 1958 in the northeast korean pine area (Xiaoxing’anling Belt and Changbai Mountain Forest) for korean pine regeneration photometry study. There are two types of metering devices available: a Luke luminometer made in Germany and a Grugell photometer. Two kinds of instruments used in the 12 Korean pine forest type under the canopy under the age of the Korean pine seedlings and young trees were measured to measure the relative density of 126 Korean pine seedlings and saplings of the corresponding minimum and corresponding high
