| 摘 要： | 从泡桐冠幅、冠长、叶面积等方面研究了泡桐的树冠生育规律,分析了树冠结构对胸径、主干高度和材积生长的影响。结果表明,影响泡桐胸径连年生长量的主导因子是冠幅连年生长量;影响主干高度连年生长量的主导因子是冠长连年生长量;影响材积连年生长量的主导因子是单株总叶面积。造林密度和人工接干能影响泡桐树冠的生长发育,从而可相应地影响主干的生长。

| Abstract: | In this paper growing and development of paulownia crown is studied in c-rown diameter,crown length and leaf area.The relations between them and thegrowth of D.B.H.,height of stem,and volume are analysed.The results showthat:(1).D(growth of D.B.H.)depends mainly on Cw(growth ofdiameter of crown).(2).The main factor affect ing H(growth of heightof stem)is L(growth of crown length).(3).There is a direct relationbetween v(volumetric gain)and A(leaf area of a tree).(4).Growing anddeveloPment of crown can be affected by density of plantation and artificialincreasing height of stem which can influence the growth of stem timberindirectly. |
