【摘要】 定植两年的幼树稳定成活后,在第3年跟踪29块10M×10M样地幼树各器官的生长情况,发现不同植株在不同月份的生长具有极显著的差异,各器官生长具有不同的相关性。树高生长与地径、总叶量、平均叶量、平均枝条大小、平均枝长等极显著相关,与分枝数负显著相关。不同植株的不同器官对树高的回归特征不同,种群中地径、总叶量对树高的回归系数较大,而分枝数对树高的回归系数最小,为-0.029。更多还原

【Abstract】 Two years after plantation,the growth of different organs of the young trees of Cercidiphyllum japonicum in 29 samples(10 m×10m) was observed in the 3th year.The result showed that the growth of different individuals in different months was significantly different,and the correlation among the growth of the different organs was different.There are significant positive correlation between the height and the ground diameter,total leaf amount,average leaf amount,average branch diameter and the average branch length,whereas the height and the number of branches was markedly negative correlated.The regression characters between the height and the different organs were different.更多还原
