红松(Pinus Koraiensis Sieb.Zncc.)是东北地区主要树种之一。红松分权虽然影响树高、材积和形数生长,但未改变立木相关生长因子之间的固有规律。由于红松分杈降低了材种质要,影响使用价值,所以在培育红松用材林时应采取技术措施,防止早期结实和过早分杈。研究结果表明,红松分杈是有规律性。分权个数为2~n(n为分杈次数),分杈与树木年龄、胸径及立地条件有密切关系最后为红松分叉立木提出新的树干解析方法,为测树工作者提供参考依据。
Pinus Koraiensis Sieb.Zncc. Is one of the major tree species in the Northeast. Although the impact of pine plantation on the tree height, volume and shape growth, it did not change the inherent law between plant growth-related growth factors. As the Korean pine bifurcation reduces the material quality, affecting the use value, so the cultivation of Korean pine woods should take technical measures to prevent the early strong and premature bifurcation. The results show that the Korean pine bifurcation is regular. The number of decentralization is 2 ~ n (n is the number of bifurcation). The bifurcation is closely related to the tree age, DBH and site conditions. Finally, a new method of tree trunk analysis is proposed for bifurcation of Pinus koraiensis in accordance with.
