1960至1692年间,对帽几山地区红松人工幼林(3.5.10年)进行了物候期及定期生长量的调查(树高、根径)、目的是要研究红松幼林的年生长周期,了解年生长周期与气象因子的相互关系,寻找提高幼林生长量的途径。对调查与观察的数据进行分析研究,发现红松幼林的高和根径等年生长可以分别配合成三次抛物线与五次抛物线公式。但这仅是对红松幼林的年生长规律的初步探讨,极不成熟,正理成交,仅供研究上述问题时的参考。
From 1960 to 1692, Pinus koraiensis artificial young forests (3.10 years) were surveyed for phenology and periodical growth (tree height and root diameter) in order to study the annual growth cycle of young Korean pine forests, Understand the relationship between the annual growth cycle and meteorological factors and find ways to improve the growth of young forest. The data of investigation and observation are analyzed and studied. It is found that the annual growth such as height and root diameter of Korean pine can be combined into cubic parabola and quintic parabola respectively. However, this is only a preliminary study of the annual growth pattern of young Korean pine. It is extremely immature and is being dealt with properly. It is only a reference for the study of the above issues.
